While maladaptive consumption and its consequences are well known, the management and regulation of such consumption is fraught with numerous issues related to definition, locus of responsibility, and potential modes of intervention. The present article provides a review of the conceptual, methodological, and policy issues surrounding maladaptive consumption. The authors suggest that marketing has an important and unique role in the design of products and regulation intended to address maladaptive consumption. Questions for future research and public policy are identified and discussed. [ABSTRACT FROM AUTHOR]

Traditional culture handicraft products have reflected to the culture and heritage of the region from which they originate. These products are typically unique, exhibiting the artisan's skill and creativity. Ensuring consistent quality can be difficult due to the handmade nature of products that leading to variability that might not meet consumer expectations and successful in the market. For it successful, innovation is always referred and considered for business success and survive in the global as well as competitiveness in the marketplace. Through innovation in traditional culture handicraft product development can lead to a new breath and sustainable in the market. In modern uses, an integrating with the modern design elements able to create the products appeal to contemporary tastes. However, the development a new innovative traditional culture handicraft product always lacks innovation strategy. Hence, the research aims to develop a new framework that integrate the design value related culture and aesthetic elements toward marketability. In this research, it was specifically evaluated the traditional culture handicraft product in Linxia, Gansu Province as a case study. To provide the background and critical issue, the comprehensive literature review was conducted with emphasis on design value, culture, and aesthetic of Linxia traditional culture handicraft products. Furthermore, the empirical investigation also conducted involved with the design experts and experienced product users through Sampling Product Analysis of Brick Carving of Linxia attempt to recognise the valuable product elements. The result found and recognised twenty-nine (29) design value related culture and aesthetic elements that significantly contribute toward marketability of Linxia traditional culture handicraft products. In addition, a new framework namely Design Value Product Culture Aesthetic (DVPCA) was developed as become a guidance for designers and craft practitioners in the development of a new Linxia traditional culture handicraft product in Hetaomin toward marketability.

Preterm infants born before 34 weeks of gestation often face respiratory challenges and may require resuscitation with an endotracheal tube and ventilator support. Unplanned extubation is a common problem for such infants, affecting their care and outcomes. This quasi-experimental study compared the incidence of unplanned extubation, stability of vital signs and oxygen saturation between a control group (n = 24) receiving routine care in a neonatal intensive care unit and an experimental group (n = 24) receiving routine care along with the use of the Endotracheal Tube Adjustable Stabilizing Set, developed by the researchers. The latter set comprises an endotracheal tube-holding cap, head-locked pillows, and an oxygen meter. Data were analyzed using descriptive statistics, t-tests, chi-square tests, and Fisher's exact tests. Results show that the control group had an average tracheal tube insertion time of 78.94 hours, while the experimental group had an average of 39.35 hours. The incidence of unplanned extubation was 33.33% (8 cases) in the control group and 4.17% (1 case) in the experimental group. The unplanned extubation rate per 100 ventilator days was 4.41 times in the experimental group, significantly less than in the control group (23.84 times). The experimental group also exhibited significantly more time spent on vital signs and oxygen saturation within normal limits than the control group. In conclusion, using the Endotracheal Tube Adjustable Stabilizing Set in neonatal care can improve patient outcomes by reducing the incidence of unplanned extubation and stabilizing vital signs. This set has passed patentability evaluation for product design and enhances neonatal care by stabilizing endotracheal tubes, reducing slippage, and helping nurses provide more effective care. However, further testing in different settings with larger sample sizes and an equal average tracheal tube insertion time between the two groups is recommended to validate these findings.

Abstract The design stage of a product plays a critical role in determining its sustainability. Key product attributes—such as reliability, durability, reusability, repairability, design for remanufacturing, recyclability, and end-of-life considerations—are established during this stage, influencing the product’s overall environmental impact. Circular product design (CPD) is a design philosophy that fosters economic growth while reducing negative environmental impact across the product’s entire life cycle. This study aims to identify circular product design strategies (CPDS) for the apparel industry, a sector known for its significant carbon footprint. Twelve CPDS are identified in this study, categorized into five dimensions of circular economy (CE): narrowing, slowing, closing, reintegrating, and technology, using the fuzzy Delphi method (FDM) with inputs from a panel of twenty-three experts. Furthermore, causal interrelationships and a prioritized list of these strategies are determined using the fuzzy decision-making trial and evaluation laboratory (DEMATEL) technique. Of the twelve strategies, five are part of the causal group, while the remainder are in the effect group. The top three causal CPDS are Design standardization, Design with responsible materials, and Design for redesign and remanufacturing. Conversely, the CPDS under the ‘effect’ group with least impact includes Multifunctional product design, Artificial intelligence in design forecasting, and Computer-aided product design. This study offers valuable managerial insights for decision-makers and designers in the apparel industry, guiding the implementing of CE practices throughout the apparel supply chain.

Abstract Background To ensure the acceptability and effectiveness of potential Multipurpose Prevention Technologies (MPTs), understanding user needs, and preferences are crucial to inform the design of MPTs. This article aims to explore the perceptions towards potential MPT use and to explore the needs of multiple stakeholders in India within their social and behavioural contexts. Methods A qualitative multicentric study was conducted in three Indian states—Maharashtra, Karnataka, and Tamil Nadu. The study involved a total of 222 interviews: 77 in-depth interviews with women, including those from the general population, HIV-positive women, and street and brothel-based Female Sex Workers (FSWs); 84 in-depth interviews with men and 61 key informant interviews were conducted. Three focus group discussions were conducted with FSWs. Interviews explored perceptions of the potential MPTs, needs, and factors that may potentially affect their use and adherence. Interviews and FGDs were transcribed and translated verbatim. Thematic analysis approach was used to analyse the data in NVivo version 8. Result The following themes highlight the need and preferences among women for the potential MPT product: 1) Overall perceptions about new MPT, 2) People at high risk need long acting products, 3) Condom versus new MPT: potential of MPT, 4) Women empowerment through MPTs 5) Secrecy and confidentiality 6) Non-stigmatising MPT product positioning. Conclusion Several stakeholders in this study expressed their need for new MPTs, but concerns regarding confidentiality, privacy, stigma and, adherence were identified. Besides efficacy, characteristics such as the size, packaging, formulation, and texture of MPTs, should be taken into account when designing the MPT products, also considering the needs of women, specially, female sex workers.

Abstract Introduction The use of oral anticancer medications has become more prevalent in cancer therapy. This is particularly the case in the management of advanced non-small cell lung cancer (NSCLC). However, when the treatment delivery interaction between the patient and the healthcare provider is removed, the risk of non-adherence increases. Insights into patient preferences can allow drug product formulation scientists to design more patient-centric medications that may promote an increase in adherence which, in turn, may lead to more beneficial health outcomes. Methods We conducted an advisory board with patients with NSCLC in the United Kingdom to elicit and understand preferences for drug product attributes related to appearance, instructions, and modality. The advisory board was preceded by a quantitative preference survey that included three object-case best–worst scaling exercises and was followed by administering the same survey to a broader group of patients to confirm the results. Results Patients strongly prefer once-daily dosing over more frequent dosing, regardless of the number of pills because taking tablets or capsules multiple times each day can disrupt daily activities. In addition, patients place high importance on surface smoothness because a rough surface implies decreased swallowability. Finally, food restrictions involving directions regarding taking medication with or without food represent difficulties for patients with cancer. Results of the follow-up survey confirmed these results. Conclusions Drug developers should attempt to limit the dosing of these medications to once-daily regimens, avoid surface roughness, and develop formulations that can be taken without regard to the timing of meals to the greatest extent possible.

Conceptual design is a pivotal stage of new product development. The function-behaviour-structure framework is adopted in this stage to help designers search design space and generate conceptual solutions iteratively. Computer-aided methods developed within this framework will yield significant insight into facilitating the cognitive activities of designers. In order to solve the mapping process from behaviours to structures which is a typical constraint satisfaction problem, a cerebellar operant conditioning-inspired constraint satisfaction approach is proposed in this paper. The design constraints-driven operant conditioning and its regulation mechanism by the cerebellum are analysed for the first time. Proposition logic is applied to transfer the constraint satisfaction problem into a propositional satisfiability problem while an undirected graph is utilised to model design space. Inspired by the modularised cerebellar structure, a modularised constraint satisfaction neural network is constructed to determine the satisfiability of design problems. Conceptual solutions can be generated by clustering the embedding of nodes in this network. The proposed approach imitates the design constraint-driven operant conditioning to narrow down design space without assigning specific values to design components. It reduces design iterations and avoids combinatorial explosions during conceptual design. [ABSTRACT FROM AUTHOR]

Visual marketing communications consist of two components: (1) semantic content (e.g., headings, images, copy) that communicates a brand's positioning, benefits, and personality and (2) visual design (e.g., font selection, image size, the organization of the content) that encourages inferences about brand claims. The authors investigate how visual design can be used to encourage inferences that support brand claims and improve brand performance. They find that brands with a utilitarian positioning perform better when the visual design of their marketing communications encourages structured perceptions, whereas brands with a hedonic positioning perform better when the visual design of their marketing communications encourages unstructured perceptions. In both cases, (un)structured perceptions encourage inferences that reinforce brand claims and, consequently, improve brand performance. This research offers actionable insights into how marketing communication specialists can coordinate logo design, product design, package design, visual merchandising, and retail environments to reinforce brand claims.

Non-advertising-based mobile apps face several critical challenges when trying to monetize their free services—among them, the choice of pricing strategies (hard landing vs. soft landing; i.e., a "pay or churn" paywall vs. continuing to offer limited free services to existing users after monetization) and aspects of product design (whether to provide exclusive secondary offerings to paying users). The authors implemented a large-scale randomized field experiment with an app firm to test the causal effects of such pricing and product design strategies. Results show that both soft landing and exclusive secondary offerings decrease existing app users' willingness to subscribe, but there is a positive interaction between these two strategies on subscriptions. The authors propose a theoretical framework, discuss potential mechanisms that might be at play, and conduct robustness checks to rule out several alternative explanations. A customer survey by the firm and an experiment on Prolific provide further support for the theoretical mechanism. To assess generalizability, the authors conducted a second field experiment and obtained consistent results. They also report the results from the actual implementation of the best-performing strategy by the firm. This research provides guidance on possible theoretical underpinnings of users' responses and important managerial implications for app monetization. [ABSTRACT FROM AUTHOR]

This paper develops a theory that generates an equilibrium relationship between product complexity, transparency, and trust in firms. Complexity, transparency, and the evolution of trust are all endogenous, and equilibrium transparency is nonmonotonic. The least-trusted firms choose the lowest product complexity, remain opaque, and substitute ex ante third-party verification for information disclosure and trust. Firms with an intermediate level of trust choose an intermediate level of complexity and transparency through disclosure, with more trusted firms choosing greater complexity and lower transparency. The most-trusted firms choose maximum complexity while remaining opaque, eschewing both verification and disclosure. [ABSTRACT FROM AUTHOR]

A contemporary business challenge for bundling theory is the distribution of digital content such as media, entertainment, software, and other information goods. Consumers can use a number of devices to interact with software, online services, music, video, news, and other forms of digital content. For instance, Netflix videos and Kindle ebooks, initially accessed only on television sets and computers, respectively, are now also consumed on smartphones and tablets. Print products are now distributed and consumed both in print and digitally. Firms offer product line designs that include prices for single device access as also bundle discounts for multi-device access, so that consumers can choose a device or even multiple devices. This paper provides guidelines regarding such multi-device product line design and pricing. A starting point is to note that there are many ways to practice bundling, from offering prices for single-device consumption as well as a bundle discount (mixed bundling), to forcing multi-device prices (pure bundling), and designs in between (partial bundling). Picking the best design, and associated prices, is a complex problem due to how single-device demand functions relate to multi-device demand. Recognizing that some dual-device purchases can occur even when there is no bundle discount, the paper develops intuition around the net gain or loss incurred from giving a bundle discount to entice single-device access buyers to dual sales. One surprising finding is that inducing dual sales through bundle discounts can be profitable even when intent to consume multiple times is quite weak, because in this case dual sales would not occur organically. Less surprisingly, such inducement is also profitable when multi-consumption intent is strong, and least attractive when the intent is moderate. When one of the devices is an emerging one or has weak own demand in the short term, then it can be useful to offer a partial bundle, tying sales for the stronger device into a bundle comprising access to both devices. When device valuations are such that consumers generally agree on the rank-ordering of the devices (e.g., if a location-based app offers greater value on a smartphone than on a tablet), then it is best to employ some type of bundling, unless the intent for multi-device consumption is proportionally lower among low-value consumers than for high-value consumers.

Ming-style furniture patterns hold significant cultural importance within traditional Chinese heritage. Despite being frequently integrated into modern Chinese product design, a comprehensive scientific investigation into the psychological framework governing people's appreciation of these patterns has been lacking. Therefore, this article employs structural equation modeling analysis to delve into the aesthetic structure of Ming-style furniture patterns. The results found that: (1) Emotion, as the dependent variable, is influenced by perceptual and cognitive factors, with familiarity being the most crucial influencing indicator. (2) The model proposed in this article exhibited no variations across age and gender groups, but did demonstrate differences based on individual expertise. These research findings not only bridge the void in empirical studies on the aesthetics of Chinese traditional patterns but also establish a theoretical foundation for enhancing the decorative impact of traditional patterns in product design.

How do consumers react to products assembled from existing components? Nine studies in both the lab and the field demonstrate that consumers evaluate products as more creative and more appealing when they consist of components that originally served entirely different functions. When consumers realize that the intended functionality of a component is not fixed, but versatile, they experience an aha! moment, which in turn enhances perceived product creativity and product appeal. This research bridges engineering and consumer research providing theoretical contributions to the product design and creativity literature. The findings of this research have substantive implications for designing sustainable products, especially for product upcycling, the process of transforming old or used components into new products.

Collaboration between firms and product users has been widely practiced to enhance the efficiency and quality of product development. We consider a collaborative product improvement setting where a sponsoring firm and product users jointly create or promote product design ideas through firm-sponsored online user innovation communities (FOUICs). Using a differential-game framework, we study a benchmark case in which product users involved in FOUICs are homogeneous in their innovative contribution capacities and propensities. We then incorporate users' heterogeneity such that product users are distinguished into lead users and common users. Our analytical result shows that the equilibrium effort levels and utilities of both the sponsoring firm and product users may increase or decrease with a change in the output elasticities of product design ideas or in the cost elasticities of the effort levels. Moreover, lead users' equilibrium effort level and utility are more sensitive to the elasticity parameters of product users' effort than those of common users, and lead users obtain a higher total incentive reward than that of common users. Last, we compare the benchmark model and the extended model to identify the condition under which one model outperforms the other one for both the sponsoring firm and product users.

While design thinking has gained popularity in product innovation, scholars argue that design thinking can also trigger and sustain organizational innovation. This study investigates the adoption of design thinking in the Design+Innovation unit at PepsiCo. It reveals nine design thinking practices that enable organizational innovation: valorizing personal attitudes and desires, engaging stakeholders in the design discourse, leveraging the design unit as an agent of change, fostering abductive reasoning, empowering decision making through prototypes, crafting proof points, absorbing external viewpoints, searching for co-conspirators, and aligning personal and organizational purposes.

Purpose: The accuracy of heart rate measured with a wrist photoplethysmography monitor can be influenced by the tightening of the wristband, movement of arms, or kinetics of the signal (eg, steady-state exercise vs on- and off-transients). To test these hypotheses, photoplethysmographic and electrocardiographic (ECG) signals were compared. Methods: Thirty participants (50% female) randomly performed two 13′ sequences (3′ rest, 5′ submaximal-intensity exercise, and 5′ passive recovery) on a motorized treadmill and a bicycle ergometer. Heart rate was measured concomitantly with a 10-lead ECG, a chest-strap monitor, and 2 wrist photoplethysmography monitors (Polar Unite) with different tightening (free vs imposed at the maximum tolerable). Results: The level of association (r) and coefficient of variation (CV; ie, the error of measurement) of the Polar Unite versus the 10-lead ECG is affected by the tightness of the wristband (normal vs high; r =.83 and.96, CV = 16.1 and 8.1% for the treadmill, respectively; r =.71 and.97, CV = 20.3% and 6.2% for the bicycle, respectively) by the phase of the signal (transition vs steady state; r =.90 and.97, CV = 9.0% and 7.6% for the treadmill, respectively; r =.93 and.99, CV = 7.5% and 3.1% for the bicycle, respectively) and movement of arms (treadmill vs bicycle; r =.90 and.93, CV = 9.0% and 7.5% during the transition phase, respectively; r =.97 and.99, CV = 7.6% and 3.1% during the steady-state phase, respectively). Conclusion: The accuracy of heart rate measured with a wrist photoplethysmography monitor is affected by the tightness of the wristband and the phase of the signal. A high tightening is required when high accuracy is expected. [ABSTRACT FROM AUTHOR]

Abstract This study focuses on the design and preparation of a thin-walled plastic chair, and its mechanical properties were investigated by high load, cyclic load and drop impact. The finite element method (FEM) was employed to accurately evaluate the chair’s safety under these forces. Additionally, the effects of important structural parameters on the loading process in different states were investigated. Furthermore, a solid plastic chair prototype was created for experimental analysis. The findings revealed that increasing the thickness of the key structural parameters enhanced the safety properties of the chair under various load conditions. Optimal results were obtained when both dimensions were set to 5 mm. The deformation errors in FEM, experimental strength analysis, fatigue analysis, and drop impact analysis were measured at 3.7%, 3.6%, and 11.7%, respectively. Similarly, the stress errors were determined to be 5.9%, 5.2%, and 6.5%. These results suggest that the structural design of the chair demonstrates excellent reliability. Studying the crucial structural parameters of a plastic chair can provide valuable insights for the scientific design and safety evaluation of thin-walled furniture.

Recently, with climate deterioration and environmental pollution, consumers are becoming more and more aware of the use of sustainable energy. In particular, the demand for electric vehicles that use sustainable energy is also increasing. In addition, due to the simple driving principle of pure electric vehicles, many electric vehicles developed by electronics companies are continuously being launched. Electric vehicles not only use renewable energy to protect the environment but also save on various usage expenses, so they are expected to become the main products in the mobile travel equipment market in the future. This study aims to explore the impact of product design dimensions on electric vehicle (EV) purchase intentions, provide a theoretical basis for companies’ differentiation strategies, and reflect the impact of product design on purchase intention. This study uses Davis’s TAM combined with environmental awareness (EA) for analysis; an online survey was conducted on Chinese (n = 468) and Korean (n = 409) consumers, both male and female, aged 20–60 years and above. We found that, for Chinese consumers, the aesthetic and symbolic dimensions do not affect perceived usefulness and perceived ease of use, but they do affect environmental awareness, while the functional dimension affects not only perceived ease of use and usefulness but also environmental awareness. For Korean consumers, the aesthetic, functional, and symbolic dimensions all affect perceived ease of use and environmental awareness, but perceived usefulness is only affected by aesthetics and environmental awareness. Through simulation analysis, the results show that perceived ease of use, usefulness, and environmental awareness all directly affect purchase intentions. Perceived ease of use and environmental awareness are particularly important for Chinese consumers, while Korean consumers pay more attention to the test drive experience and environmental awareness. The results show that electric vehicle manufacturers should develop new technologies for the Chinese market to attract consumers, while in the Korean market, they should improve perceived usefulness through test drives and pay attention to environmental awareness. Specific statistical data show that both Chinese and Korean consumers assign importance to the impact of environmental awareness on purchase intention, proving the importance of environmental awareness. The results of this study will be of great reference value to electric vehicle manufacturers, policymakers, and consumer behavior researchers, helping them to better understand the role of product design in improving the market acceptance of electric vehicles.

The furniture industry is one of the industrial sectors that has a potential market in Indonesia. This industry requires a lot of wood raw materials but is faced with a wood legality verification system that limits raw materials. Industrial players still need to start using waste as raw materials, which will reduce the use of primary raw materials. The circular economy concept can be applied to waste treatment. This study aims to design a pump-gallon product made from waste, considering the relatively high level of gallon container consumption. With this design, it is hoped to utilize waste into economically valuable products while reducing the environmental impact it causes. The product design process uses an integrated QFD-TRIZ method combined with circular economy principles. QFD functions to determine consumer desires and make technical responses, while TRIZ resolves contradictions in technical responses. The circular economy attribute is used as a reference in making gallon pump products from wood waste. After the design process is complete, it is followed by an economic feasibility analysis using the cost-benefit ratio. The result of this research is the design of multifunctional and modular products for gallon pumps. The gallon storage is designed to store not only gallons but also a small table for placing dirty glass and a drawer at the bottom that can be used to keep the glass or other items. There is a detachable system between the upper and lower components, making it easier to repair and use. At the bottom, they mounted castor wheels to facilitate product movement. Designing products made from waste will increase the income of furniture SMEs. In addition, it is expected that this will overcome waste management problems and shortages of raw materials experienced by furniture SMEs. Future research can utilize powder and smaller pieces of wood.

Interpreting and incorporating machine learning technology from a human perspective helps define the role of product designers in the era of artificial intelligence. With this background, this study developed a 7-week design course about machine learning-based product design. Subsequently, in Fall 2023, a class with seven undergraduate students from different majors was held on the subject of “home camera.” The design process consisted of (a) user research and need definition based on machine learning understanding and (b) machine learning-based interaction design development using a coding platform. The course was designed to explore the role of designers who implement human-centered design planning and prototypes considering machine learning tools. In addition, the course provided a basis for suggesting the direction of design education methods given emerging AI technology. The essence of design education is not merely about efficiency; rather, it is about nurturing designers’ ability to think critically and use tools to cultivate innovation.

Biodegradable heart occluder uses a biodegradable medical polymer material to replace or completely replace the metal material. After completing the repair function of the heart defect, the device is gradually degraded and safely absorbed by the human tissue. So it may minimize the risk of long-term complications that traditional metal heart occluder causing in the body after implantation. Based on the quality management concept of the entire lifecycle of medical device, this article briefly introduces design and development, as well as the product realization of biodegradable heart occluder. It analyzes the main risk points in design and production, and corresponding suggestions have been put forward. These suggestions are combined with the medical device good manufacturing practice and the appendix of implantable medical equipment to provide a reference for regulators and industry professionals.

Abstract User requirements serve as the primary reference content in product design. The effective capture of crucial user requirements, followed by the development of a product technical solution aligned with these requirements, stands as a pivotal approach to enhancing design efficiency. In order to explore the problem of generating and decision-making of product technical solutions in the case of complex user demands, this study constructs a user requirements driven product optimization design model, which is used to complete the generation and decision-making of product design solutions in a more reasonable way. The model unfolds across three key stages: Firstly, a user requirements importance ranking system is crafted leveraging Kano Model and Pairwise Analysis. Next, employing the Functional Analysis System Techniques (FAST) theory and the Quality Function Deployment (QFD) theory, user requirements undergo transformation into technical solutions. Finally, these technical solutions are amalgamated into diverse technical combinations, with decisions facilitated by a game theory model to yield the optimal overall design solution. The new optimal design model reduces the influence of subjectivity and ambiguity in the process of user requirements analysis, increases the reliability of the transformation of user requirements into technical solutions, and improves the efficiency of the generation and decision-making of product design solutions under multiobjective situations. The model proposed in this study is exemplified through the development of a medicated bath water heater. Results indicate that the technical solution derived from the model surpasses similar products in terms of user satisfaction, thereby validating its feasibility.

Design for assembly (DFA) is a common engineering technique aiming to reduce assembly costs, increase productivity, and reduce parts cost and material flow. Traditional DFA methods are based on CAD modelling and analysis using specific algorithms comprising the DFA rules. However, such traditional approaches lack of practicality and capability to consider the assembly know-how of designers and manufacturers. In order to overcome some of the limitations of current DFA methods, in this paper a new DFA system based on a haptic-enabled virtual reality approach is proposed. The proposed system, named haptic-enabled VR design for assembly (HVR-DFA), is able not only to simulate the product assembly and collisions among parts, but also to evaluate the product design and assemblability, and to automatically generate assembly planning data from the virtual assembly task execution. Consequently, the user can interactively assess DFA rules and part interferences during the virtual assembly execution. To evaluate the feasibility of the system, a case study corresponding to the assembly of a mechanical component is presented and analysed. The results have demonstrated that the proposed system is an effective DFA tool and more practical than the traditional methods. Moreover, it benefits from the know-how of the assembly experts.

Additive Manufacturing has significantly impacted circular design, expanding the opportunities for designing new artifacts following circular economy principles, e.g., using secondary raw materials. Small-format 3D printing has reached a broader audience of stakeholders, including end-users, when dealing with filament feedstocks from plastic and biomass waste. However, using large-format extrusion-based additive manufacturing with recycled feedstocks remains challenging, resulting in limited applications and awareness among practitioners. This work analyzes the most relevant product applications using large-format material extrusion additive manufacturing with recycled plastics and biomass waste feedstocks. It reviews the case studies from 2010 to mid-2024 dealing with new materials and applications from academic research and practical contexts. The applications were analyzed to outline the current situation and trends for large-format 3D printing with recycled plastics- and biomass-based feedstocks, focusing on secondary raw materials, manufacturability, impact on product aesthetics, application fields, and products. Despite more consolidated sectors, new technical applications using granulate feedstock systems, e.g., transportation, are emerging. Academic research studies new secondary raw materials and distributed practices through large-format 3D printing. Practitioners are exploiting different approaches to design products, optimizing building times, costs, and material usage through different manufacturing strategies, strengthening the product identity by highlighting circularity. Spreading specific expertise could enlarge the range of application sectors and products, as well as foster real-world collaborations and scaling-up. Thanks to this work, new synergies between the research and practical contexts can be encouraged for new circular economy practices, detecting and exploring new scraps, material categories, or Additive Manufacturing processes in the future.

As a part of the service industry, product design practitioners should possess an understanding of the multifaceted factors and solutions that contribute to delivering exceptional service quality. However, related research on the service quality factors and solutions for China's ceramic product design industry is still an important research gap. In view of this, an integrated approach based on multi-criteria decision making (MCDM), combining the fuzzy analytic hierarchy process (FAHP) and the measurement of alternatives and ranking according to compromise solution (MARCOS), was proposed in this research to analyse and evaluate the service quality factors and solutions for China's ceramic product design industry. Initially, the FAHP method determined the significance of the service quality dimensions and indicators. Subsequently, the MARCOS method ranked the alternatives based on their performance against these criteria. This research focuses on the growing subject of service quality in China's ceramic product design industry. The proposed model identifies essential service quality factors and solutions for China's ceramic product design industry. The findings of this study may assist ceramic product design practitioners in China in making strategic decisions to provide excellent service quality. [ABSTRACT FROM AUTHOR]

Background: This study aims to evaluate the efficacy of an oxygen scavenging mask device in reducing local oxygen concentrations from nasal cannula ventilation compared to a standard open facial surgical field. Methods: This is a controlled experiment using a custom-fabricated silicone midfacial oxygen scavenging device, SimMan airway management trainer manikin (Laerdal Medical, Stavanger, Norway), handheld oxygen detector (Forensics Detectors, Los Angeles, United States) and oxygen from a Datex Ohmeda Aisys Carestation anesthesia unit (GE HealthCare, Chicago, United States). Oxygen concentrations were measured at 18 facial landmarks (Fig. 1) with nasal cannula flow of 2, 4, and 6 L/min of 100% FiO2 in both masked and unmasked conditions (Fig. 2). Results: The mean oxygen concentration in the facial surgical field was 20.95% with the scavenger mask and 24.8% without (P < 0.001; two-tailed paired t-test). The unmasked condition was associated with suprathreshold oxygen concentration levels at 13 of 18 facial landmarks (Table 1). The device significantly reduced local oxygen concentration at 16 of 18 facial landmarks (Table 1). The device provided safe oxygen concentration levels at all three flow rates, and measured oxygen concentrations directly correlated with oxygen flow rate in the unmasked condition (Table 2). Conclusions: An oxygen scavenger mask device reduced local oxygen concentrations from nasal cannula ventilation to below the 23% fire threshold in the entire facial surgical field external to the mask in these experiments. The device may reduce intraoperative fire risk in patients that require supplementary oxygen during surgery. [ABSTRACT FROM AUTHOR]

Noninvasive respiratory support delivered through a face mask has become a cornerstone treatment for adults and children with acute or chronic respiratory failure. However, an imperfect mask fit by using commercially available interfaces is frequently encountered, which may result in patient discomfort and treatment inefficiency or failure. To overcome this challenge, over the past decade, increasing attention has been given to the development of personalized face masks, which are custom-made to address the specific facial dimensions of an individual patient. With this scoping review, we aim to provide a comprehensive overview of the current advances and gaps in knowledge with regard to the personalization masks for CPAP and NIV. We performed a systematic search of the literature and identified and summarized a total of 23 studies. Most studies included were involved in the development of nasal masks. Studies that targeted adult respiratory care mainly focused on chronic (home) ventilation and included some clinical testing in a relevant subject population. In contrast, pediatric studies focused mostly on respiratory support in the acute setting, whereas testing was limited to bench or case studies only. Most studies were positive with regard to the performance (ie, comfort, level of air leak, and mask pressure applied to the skin) of personalized masks in bench testing or in human, healthy or patient, subjects. Advances in the field of 3-dimensional scanning and soft material printing were identified, but important gaps in knowledge remain. In particular, more insight into cushion materials, headgear design, clinical feasibility, and cost-effectiveness is needed before definite recommendations can be made with regard to implementation of large-scale clinical programs that personalize noninvasive respiratory support masks for adults and children.

Background: Medical-product companies often outsource research and manufacturing needs to contracting or partnering organizations but then must manage a challenging patchwork of regulatory activities. A standalone regulatory agreement could clarify the relationships and responsibilities between companies working jointly on a single regulated product. This study explored the need for and current use of standalone regulatory agreements. Methods: A survey instrument was developed using an implementation framework and disseminated to mid- to senior-level employees and consultants for sponsor and vendor companies in the medical products sector. Results: Of 294 respondents, about half, primarily from companies with more than 200 employees, were familiar with standalone regulatory agreements, and half of this subgroup had moved forward to implement them. Such agreements were considered beneficial to clarify regulatory roles and responsibilities, standardize regulatory expectations between the companies, and stimulate earlier discussion about joint regulatory strategies. However, the development of regulatory agreements appears challenged by the fact that such agreements are not required by regulatory agencies overseeing medical products and have no standardized templates, agency or industry guidance. Respondents whose organizations do not now use regulatory agreements either had not considered or did not see a need for a standalone agreement. Conclusions: Standalone regulatory agreements are becoming more common but are not yet implemented fully by most companies. Their usefulness and content appeared to depend upon the type of partner, the complexity of the relationship and the availability of internal expertise and support. [ABSTRACT FROM AUTHOR]

This paper presents an integrated approach for joint decision-making in reliable product design and resilient supply chain network design within a two-echelon capacitated network. Our methodology simultaneously addresses two crucial decisions faced by manufacturing industry by integrating the design processes of modular products and their supply chain networks, allowing for multiple production facilities and product variants. Through redundancy allocation, we optimize product reliability within production facilities while considering component sourcing from multiple suppliers. Our approach employs three resilience strategies—multi-sourcing, supplier fortification, and backup supplier contracting—to enhance supply chain resilience against disruptions. A case study solved using a genetic algorithm demonstrates the effectiveness of different resilience strategy combinations in achieving various levels of production resilience. This research offers insights into integrated decision-making for enhancing product reliability and supply chain resilience, thereby providing valuable guidance for industry practitioners. Furthermore, the sensitivity analysis highlights the framework's capability to minimize total costs by prioritizing resilient designs and strategically investing in resilience strategies as costs of production shortage increase. This analysis underscores the interconnected nature of product and supply chain network design decisions in mitigating disruptions and enhancing production resilience.

With the outbreak and continued spread of the COVID-19 pandemic, people's demand for daily disinfection products has increased rapidly, and its innovative design has received widespread attention. In this context, this study aims to propose a design methodology for home entrance disinfection devices based on AHP-FAST-FBS. Firstly, the design requirements of the home entrance disinfection device were collected and analyzed through in-depth interviews and the KJ method, and a hierarchical model of design demand indicators was constructed. Secondly, the Analytical Hierarchy Process (AHP) was employed to quantify these design demand indicators, and core design demands for home entrance disinfection devices were identified by weight calculations. On this basis, the Functional Analysis System Technique (FAST) method was combined to rationally transform the design demands into product functional indicators, constructing a functional system model for the home entrance disinfection device through systematic decomposition and categorization. Lastly, based on the Function-Behavior-Structure (FBS) theoretical model, the mapping of each function of the product to its structure was realized, the product structure modules were determined, and the comprehensive design and output of the innovative design scheme for the home entrance disinfection device were completed. The results of this study indicate that the design methodology combining AHP-FAST-FBS can effectively improve the scientific rigor and effectiveness of the home entrance disinfection device design, thereby generating an ideal product design scheme. This study provides systematic theoretical guidance and practical reference for designers of subsequent related disinfection products and also offers a new path for improving social health and safety.

Aims: To describe the development process of a device from the conception of the idea to the first contact with the commercial environment, and to demonstrate its practical application through an interdisciplinary collaboration between nursing and engineering for the design of a protective device for peripheral venous catheters. Background: Nurses are key agents for identifying unresolved needs or problems related to nursing care. To address these needs, creative ideation processes are often triggered among nurses to seek technological answers to these challenges. Results: The ten steps to develop a device are presented: (1) detecting an unsatisfied clinical need; (2) searching for preexisting marketed products; (3) searching for patents; (4) maintaining confidentiality throughout the process; (5) obtaining institutional support; (6) forming a multidisciplinary team; (7) developing the idea; (8) applying for a patent; (9) building the prototype; (10) marketing the device. This methodology was applied to design a protective device for peripheral venous catheters in hospitalized patients. Conclusions: Nurses can play a key role in the promotion of healthcare innovation in their field to improve procedures, thanks to their direct contact with patients, and by providing their insight on devices that can enhance patient care. The successful interdisciplinary collaboration between nurses and engineers can provide a response to relevant clinical problems such as the manipulation or removal of peripheral venous catheters. Implications for nursing and/or health policy: A hospital policy is required to encourage the participation of nurses in innovative actions. Furthermore, it is important to support nurse leaders who can play a pivotal role in incorporating creativity into work environments and empowering other nurses to innovatively address clinical issues. No patient or public contribution: This article describes the process for developing a health device. [ABSTRACT FROM AUTHOR]

This study analyzed collaborative invention projects by teams of lower-secondary (13–14-year-old) Finnish students. In invention projects, student teams design and make materially embodied collaborative inventions using traditional and digital fabrication technologies. This investigation focused on the student teams' knowledge creation processes by examining how they applied maker practices (i.e., design process, computer engineering, product design, and science practices) in their co-invention projects and the effects of teacher and peer support. In our investigations, we relied on video data and on-site observations, utilizing and further developing visual data analysis methods. Our findings assist in expanding the scope of computer-supported collaborative learning (CSCL) research toward sociomaterially mediated knowledge creation, revealing the open-ended, nonlinear, and self-organized flow of the co-invention projects that take place around digital devices. Our findings demonstrate the practice-based, knowledge-creating nature of these processes, where computer engineering, product design, and science are deeply entangled with design practices. Furthermore, embodied design practices of sketching, practical experimenting, and working with concrete materials were found to be of the essence to inspire and deepen knowledge creation and advancement of epistemic objects. Our findings also reveal how teachers and peer tutor students can support knowledge creation through co-invention. [ABSTRACT FROM AUTHOR]

As we strive to improve efficiency and minimise environmental impact in the construction industry, it is important to consider how these objectives impact the work and productivity of designers. This article presents a tool to assist designers in matching reclaimed building products with design intent. The demonstration is based on an actual design project of a two-storey public building made of reclaimed timber from disassembled barns. The algorithm's objective is to propose optimal matching in terms of a structure's environmental impact without overloading the user with additional work or excess information. The impact includes emissions embodied in material and related to the transportation from the donor site. The algorithm is integrated into the Grasshopper interface for easier use. All the inputs and objectives are quantitative and fully customisable. The user can still assess qualitative characteristics thanks to a graphical representation of the result. The demonstration shows how automation can simplify the design process with reclaimed elements, support traditional design workflows and enable improvements towards a more sustainable construction industry.

Redesigning existing parts is challenging without keen insights into capabilities afforded by AM and with the absence of systematic design methods for the early product design stage. Therefore, this study proposes a systematic design method to leverage fully AM design benefits for reconceptualizing product architecture, which leads to consolidate parts and simplify product architecture. The proposed design method consists of four steps to achieve the goal. First, a baseline product architecture should be identified as a starting point of reconceptualization. Second, candidates for reconceptualization are identified by design principles for AM. Third, AM design benefits are recommended by the developed knowledgebase and query language, which can replace functions of the candidates. AM design benefits are applied to reconceptualize existing part design and lead to more efficient product architectures. Lastly, the reconceptualized product architecture is evaluated. To demonstrate usefulness of the proposed method, a case study is performed on an electric motorcycle. [ABSTRACT FROM AUTHOR]

New gambling products have been developed over time as technology permits. For example, early mechanical slot machines were later replaced by electronic gaming machines (EGMs), which enabled a faster speed of play and more immersive experience. EGMs have in the decades since their invention become one of the main drivers of gambling expenditure worldwide and are one of the gambling products most strongly associated with harm. This literature review considers research relevant to a new subcategory of EGM, 'skill-based' EGMs, termed 'SGMs' here. SGMs can be highly varied in content, with some representing a minimal departure from EGMs, where the typical bonus round is replaced by some skill-based activity, such as a simple video game, which could increase the machine's appeal. Other SGMs feature more radical departures from conventional EGMs, such as multiplayer games using intellectual property from popular TV shows or video games. These skill-based elements could tap into common gambling fallacies such as the illusion of control, and therefore facilitate harmful engagement. SGMs could also be less harmful than current EGMs, if skill-based elements break the dissociative states associated with EGM gambling. The intellectual property used in SGMs may increase their appeal among people who generally do not gamble, and the skill-based elements could increase their interest among gamblers who predominately prefer skill-based gambling formats such as sports betting. The novelty and varied content of SGMs present many open questions, which research should aim to address in future. [ABSTRACT FROM AUTHOR]

This article examines the role of product design in improving the lives of individuals from povertystricken societies. Despite the perception of well-designed products being a privilege, it is essential to recognize the universal need for functional and purposeful products. As issues related to climate change and economic recession disproportionately affect lower-income communities, creative problem-solving can become an effective way to support them in overcoming these issues. Issues ranging from water scarcity to underdeveloped agriculture systems have been addressed through the introduction of new products into underprivileged communities. The impact of these products is evaluated based on user feedback and their effectiveness in improving users' lives. The outcome will identify the significance of the role of product design in improving the livelihood of poverty-stricken societies. This will benefit governmental and non-governmental organisations seeking effective solutions to support individuals in need and product designers who are interested in designing for humanitarian purposes. By highlighting successful instances where product design has positively impacted the lives of impoverished individuals, these organisations may be more inclined to collaborate with designers and provide the necessary funding for such initiatives.
