- Abstract
Today the assembly sequence for the products is often carried out manually and its definition, typically, is very expensive, not guaranteeing optimal solutions. Coming up with an efficient assembly sequence is the essential step to improve process productivity and reduces the time and costs related to assembly machines and equipment. The issue related to the assembly sequence of a product depends on the total number of the its components. In particular, the number of the possible sequences can be obtained through the calculus of the factorial of the number of the product components. This work presents an automatic approach intended to define assembly sequences, based on the information regard the contacts and the interferences existing among the components, which is obtained by the assembly CAD model of the product. The level of the information required by this approach allows its implementation at early stages of design, as soon as the layout of the conceptual solution of the product is defined, independently by the method used to model the CAD assembly. The procedure proposed is focused to obtain a reduced number of assembly sequences, guaranteeing that there is at least one feasible assembly sequence among them. The procedure is oriented to iteratively identify independent and important subassemblies into the CAD assembly, then merge them to specific assembling nodes and generate sequences until the whole product is analyzed. After a brief review of current methodologies developed for assembly planning, in this paper, the automated procedure for assembly sequence generation is explained and applied on an example, obtaining feasible solutions. © 2012 Springer-Verlag. more...

- Abstract
Solar cars are known for their energy efficiency, and different races are designed to measure their performance under certain conditions. For these races, in addition to an efficient vehicle, a competition strategy is required to define the optimal speed, with the objective of finishing the race in the shortest possible time using the energy available. Two heuristic optimization methods are implemented to solve this problem, a convergence and performance comparison of both methods is presented. A computational model of the race is developed, including energy input, consumption and storage systems. Based on this model, the different optimization methods are tested on the optimization of the World Solar Challenge 2015 race strategy under two different environmental conditions. A suitable method for solar car racing strategy is developed with the vehicle specifications taken as an independent input to permit the simulation of different solar or electric vehicles. more...

- Abstract
The shape of a wind turbine blade plays a critical role in the efficiency and robustness of energy production. In particular, the Wavy Leading Edge is a morphology that can be implemented in the blades to improve the operating range in unsteady conditions. The best performance is achieved by fine-tuning the blade geometry to the specific context. An aerodynamic exploration of these kinds of morphologies implies generating and evaluating design iterations. Accordingly, this work presents the development of the generative tool Albatros Create ®. Through interactive visualization, infographics, and centralized parameterization, its goal is to support the geometrical definition of the aerodynamic surfaces of horizontal-axis turbines with or without a wavy leading edge. New airfoil profiles can be created, and 3D models of the rotors designed can be automatically generated. The software was implemented in the design of two rotors which were then recreated in a benchmarking analysis with four other softwares. None of the four managed to generate the smooth surfaces in fully-editable models that were achieved with Albatros Create. This work aims at empowering the research community with a user-friendly tool for exploring rotor designs through virtual prototypes. This can help to integrate further the design, modeling, and optimization stages, addressing a wider audience and facilitating the implementation of Wavy Leading Edge morphologies. © 2020, Springer-Verlag France SAS, part of Springer Nature. more...

- Abstract
Decision-making activities affect to a larger extent the quality, cost, time and success of a product. However, there are fewer alternatives when it comes to supporting in aesthetic evaluation during the product design stages. Therefore, is proposed a Crowdsourcing Augmented Reality Environment (CARE) that use the user's mobile devices for getting the feedback from the evaluation of products using a Semantic Differential (SD) that consider the user's context-light interaction in real time. Finally, two products were evaluated using CARE vs. the real products under different lighting and surrounding conditions. Obtaining a similar measure of products aesthetic perception between CARE and the real product, with slight variations. Additionally, an evaluation pattern among users was recognizable in the same context with slight variations using different lighting setup, that was similarly recreated with CARE. © 2018 Elsevier B.V. more...

- Abstract
Concentrating Photo Voltaic (CPV) systems maximize energy harvested from the sun with multi-junction solar cells of less area, reducing related implementation costs and reaching energy production thresholds up to 38,9 %. Nowadays, CPV systems are generally implemented in solar energy farms in a permanent location, however, these systems could be used in other dynamic contexts, such as vehicles or portable devices. In this way, mechanical and geometrical parameters related to manipulation, transportation and installation should be carefully considered at the design stage. Besides, each condition of use presents different variables affecting these parameters. In all, there is not an established architecture for these systems, opening up the possibility of radically changing their use, geometry and components. Therefore, a concept of a methodical process for designing of CPV systems is proposed in order to predict their behavior in terms of implementation and energy production. This might allow the development of robust concepts that can be adapted to different context of use as required, providing an itinerant character and thus extending the field of implementation of these systems beyond a static use. The relevant variables for the use of CPV systems are determined through experimentation considering the implementation of Fresnel lenses as light concentrators. This allows generating a structured design guide composed of different methods of measurement, selection and development. The methodical process is based on a perspective of functional modules considering needs, technical aspects and particular usage conditions of each design and it would provide appropriate guidelines in each circumstance. more...

- Abstract
For about 5 years, production of automobiles equipped with head-up display (HUD) systems has continuously grown and this trend will remain for at least three years more from 2014 [7, 19]. Therefore, looking for clarifying how to orientate future efforts in developing these systems, a systematic analysis approach has been implemented for identifying best design practises, common characteristics, gaps, implementation trends and research topics on automotive HUD systems. The proposed approach is conducted on two areas, firstly exploring the current scientific literature to find the most relevant research topics and understanding how these are evolving. Secondly, a competitive intelligence analysis was conducted compiling patents related to automotive HUD systems. This analysis was specially oriented towards determining, currently and in the near future, basic product design implementation trends in automotive HUD systems. Finally, the results obtained from both scientific and technological points of view were compared and commented, looking for determining common, converging or diverging, evolution parameters in automotive HUD systems. In this way, the results exposed the distraction as an outstanding research topic for these systems, becoming even more crucial if they are mixed with augmented reality projections, advanced driver assistance systems (ADAS) or infotainment systems. © 2016, Springer-Verlag France. more...

- Abstract
Nowadays, engineering programs with Problem Based Learning methodologies, develop functional prototypes for demonstration purposes. Most of these ideas, many of them promising, are left behind once the academic term is over. Only a slight percentage of them are followed by an industrialization process, which is not formalized and it is based on third-party experiences. Even if well-known product design methodologies include some methods and activities oriented to evolve the product along its life cycle, they are not suitable for academic projects or they leave out some aspects of the local context. This has been an unexploited area, with high potential as there is no transcendence with academic projects; especially after all the time, effort, and creativity employed into a potentially profitable idea. In this way, the authors propose a methodology intended to allow the transition from academic functional prototype to a product ready to be industrialized according to the capabilities of the local context. Emerging economies, where industrial capabilities may be limited. The development of the methodology has been applied in a case study of an individual electric vehicle. This vehicle was developed with students and researchers within the Design Engineering Research Group (GRID) and it is intended to transport the persons responsible to distribute mail, and packages internally in the University campus. The object of such a case is to study the feasibility to promote this vehicle from functional prototype to a product ready to be industrialized under local industrial constraints. © 2015, Springer-Verlag France. more...

- Abstract
In Colombia, air pollution problem is mainly caused by land transport, with a considerable number of internal combustion engine vehicles, and a motorcycles segment preference, electric vehicles emerge as an innovative solution to this problem. However, the country is not ready to adopt this technology on a large scale. In this way, this document proposes the development of the Quality Function Deployment (QFD) methodology in order to define and categorize Engineering Characteristics (EC) of an electric hybridization kit for motorcycles in the Colombian context. The proposed kit is oriented to the Street\sport segment, with an engine displacement between 111 c.c and 135 c.c. Besides, a technical and competitive analysis of the kit, with direct competitors in the Colombian context, based on the requirements provided by a multidisciplinary group of engineers and potential users is presented. Finally, the results obtained from the methodology implementation are classified according to the PDS categories proposed by Pugh for a further stage of product design. © 2018 Institution of Engineering and Technology.

- Abstract
Computer tools usage has became one of the major trends in humanity and product design processes are not stranger to this situation. That is the reason why different computer tools (hardware and software) have been developed in order to support design tasks, enabling design processes to achieve more innovative solutions by offering more time to creativity. Nevertheless, the quantity and variety of available tools bring a high level of complexity and their articulation becomes an important need to be tackled, aiming to integrate hardware and software applications onto a single platform. This article describes the development of a collaborative design environment supported by the usage of computer tools for product design processes. The proposed model is based on the integration of different commercial hardware into a single platform. It is meant to support product design meetings of collocated design teams in a work station where all team members can interact with design concepts in a synchronous way. After the construction of a first functional solution, a redesign process was conducted to develop a platform where key aspects such as functionality, aesthetics and ergonomics were considered. Finally, the proposed solution is not only intended to perform as a stand-alone platform, but also as a networked workstation that will allow distributed design processes. © 2014 Published by Elsevier B.V. more...

- Abstract
Photovoltaic (PV) applications such as in the architectural, automotive, and aerospace industries face design contradictions because they are expected to produce a lot of energy but are constrained by available area, surface shape, incident irradiance, shadows, and other aspects that have a negative influence on the energy produced by the solar panel. Solar competition vehicles are some of these challenging PVapplications. The design of such solar arrays needs to consider efficiency evaluation in order to optimize space; it is difficult not to install solar modules in areas impacted by shadows. A design procedure for a solar array configuration based on shadow analysis for competition vehicles is presented. The principle is that shadows in moving objects can be simulated, since the vehicle, the earth and the sun are are moving in semipredictable patterns, thus net energy collection can be forecast. The case study presented is the solar array design of a vehicle that participated in the World Solar Challenge 2013. The obtained results illustrate how the employment of the procedure gives insights on important aspects to consider and also delivers qualitative and quantitative information for decision making. In addition, the experience in competition highlights some issues to be considered, modified, or improved in further vehicle designs. © 2015 Society of Photo-Optical Instrumentation Engineers. more...

- Abstract
Wind turbine selection is a critical engineering problem in the overall cost-effectiveness of a wind project. With the wide spreading and democratization of wind energy technologies, non-expert stakeholders are being faced with the challenge of selecting among very different wind turbines. As a comprehensive indicator, the cost of energy can serve as a guide, but reportedly misleading publicity and commonly unavailable information render its calculation more inaccessible and less reliable. Accordingly, this work proposes a method to compare wind turbines, on the basis of the cost of energy, from only nominal specifications and a standard characterization of the local wind conditions. For this endeavor, it was identified that two key variables are not usually available at a preliminary stage: the total efficiency and a feasible hub height. Through a systematic statistical analysis of the trends in a constructed dataset of 176 turbines, it was possible to establish regression models for the estimation of both variables. These models were tested in a validation set and their estimations were found to correctly characterize the central trend of the data without significant deviations. The uncertainty related to the use of both models was addressed by analyzing the 95% Prediction Intervals and the stochastic rank dominance. The established statistical models were then used as the core of the proposed selection method. When the available information is limited or not trustworthy, the steps of the method can be followed as an approach to estimate the cost of energy of a given horizontal axis wind turbine in a given location. © 2018 Elsevier Ltd more...

- Abstract
This work presents an analysis about how the performance of silicon photovoltaic cells is influenced by the use of epoxy resin as encapsulation material with flat roughness. The effect of encapsulation on current at maximum power of mono-crystalline cell was tested indoor in a solar simulator bench at 1000 w/m and AM1.5G. The results show that implementation of flat roughness layer onto cell surface reduces the maximum current inducing on average 2.7% less power with respect to a cell before any encapsulation. The losses of power and, in consequence, the less production of energy are explained by resin light absorption, reflection and partially neutralization of non-reflective coating. © The Authors, published by EDP Sciences, 2017. more...

- Abstract
In most of the surrounding discrete products, style plays a very important role. Specifically, color has a great impact in the visual perception, and its meaning can vary depending on the context where the product is located. Anyway, there are not dedicated applications devoted to support designers during this activity of color selection in the conceptual stage of the product design process. In this way, this paper presents the development and evaluation of a software platform that allows the user to choose a scheme of colors of a product concept using a Natural User Interface (NUI) in a 3D scanned context. In addition, the NUI was validated and evaluated with a case study oriented to compare the scheme of colors, for a conceptual product, selected by product designers, an expert panel and the target user in order to prove that this interface can enhance the process of color selection during the concept stage of the product design process, with regards to a traditional selection process with images and user profile. © 2015, Springer-Verlag France. more...

- Abstract
The use of mobile devices inside vehicles while driving is generating an imminent safety risk. Due to this situation, one of the most relevant solutions is the Head-Up Display (HUD) system, which displays information about the system, status, and aids of the vehicle and a little data of the in-vehicle entertainment in the driver’s field of view during the driving activity. In fact, it is important to establish some guidelines or parameters to design HUD interfaces, since the automakers do not disclose their guidelines for the overall design of these interfaces. The main approach of this article is to propose a methodology for the design of automotive HUD interfaces, considering information from the ADAS, IVIS and external devices that meet the current needs of drivers. A validation of the methodology was made with product design engineers and computer engineers. It was concluded that predominantly in the designs the classification of information depending on the level of importance is clear. In this case, driving information is the most relevant in the whole design. An important aspect concerning the implementation of HUD devices is that this technology has more relevance in automotive interior design looking for a perfect balance between the primary task, driving, and the secondary task, multitasking activities on nomadic devices. © The author; licensee Universidad Nacional de Colombia. more...

- Abstract
The design of a battery pack commonly deals with high performance goals and challenging constraints in terms of cost, volume or weight. One of the most crucial variables to maximise is the nominal energy, which depends on the number of discrete battery cells that can be allocated and their individual technical specifications. This work proposes a systematic method to optimise the nominal energy of a constrained battery pack from the perspective of the series-parallel topology. A mathematical and graphical characterisation is presented on how the main battery's variables are related to a topology bounded to discretisation procedures. It was theoretically found that the effects of rounding the values of the topology may lead to a considerable loss of potential nominal energy, a risk that increases linearly with the number of series. The behaviour of the battery is assessed under nominal conditions and under the event of a cell failure. The theoretical analysis suggests that the detrimental effects due to an open-circuit increase as the number of series increases, while it is the opposite in the case of a shorted cell. The method is satisfactorily implemented in the development of two different battery packs for solar competition cars with limiting regulations. The candidate topologies outperformed the nominal energy of topologies defined without the method in up to 5%. It was also found that selecting an energy-maximising topology is not always the most convenient choice, because other variables may be of interest and are dependent on the topology as well. The method is of great use to guide the topology definition process in early theoretical stages, which is usually a compromise between allocating as much cells as possible within constraints, and approaching other performance goals such as a given nominal voltage or capacity.

- Abstract
The use of Augmented Reality (AR) to support assembly tasks has been an area of interest from its origins in the 90s. Since then, the benefits that this technology could bring to assembly-related tasks have been shown. And, although several advances have been done in different areas such as software, hardware, and human interaction, there are still some problems that have not allowed AR to expand and reach its full potential. Thereby, authors propose a real-time vibrotactile guidance method based on the Gestalt continuity principle and developed a Haptic Augmented Reality application with a low-cost configuration to evaluate the support of the proposed method in assembly tasks. Thus, it potentially overcomes the existing visual issues of AR allowing the user to focus on the task and avoid over-reliance into the technology. The proposed system recognizes the different parts and sub-assemblies, generates the instructions to perform the assembly based on the target position and rotation of each part and verifies the assembly. Additionally, a test was conducted to guide the user in positioning a part, obtaining a high accuracy of rotation and location placement. Also, different functions of the application were tested and the results are suitable for supporting the user guidance. © 2019, Springer-Verlag France SAS, part of Springer Nature. more...

- Abstract
Commonly, ergonomic analysis of the products' assembly processes starts in the embodiment design phase, when the information of the parts and their interaction are clearly defined. This may imply iterations during the design process for making improvements associated with ergonomic issues. We asked whether it is possible to infer possible ergonomic issues related to the manual assembly process during product conceptualisation. So, we integrated an AR-based modelling tool, in which the user creates and places virtual parts over the context in a top-down design strategy using his/her hands as interface, with an Ergonomic Assessment Module for continuous evaluation of the user postures, movements and forces related to the created parts. In that way, the spectrum of the potential solutions during the conceptualisation phase, when the information about the problem is vague enough, can be delimited and the convergence to the near-optimal solution may be more effective. more...

- Abstract
Precise control of technical system variables in industrial processes and manned and unmanned missions is critical as their results should be achieved plenty. This takes place in Control Rooms (CR) where Operators make decisions based on the large amount of received data. This work proposes a method for weighting variables of a technical system based on their impact on the mission objectives. The relationships between variables and mission functions are defined using a Function to Data Matrix (FDM) in order to allow Operators to determine their criticality. The proposed method was applied for the mission control of the Racing Solar Vehicle Primavera1 which participated in the World Solar Challenge (WSC) 2013 in Australia. more...

- Abstract
The design process of an object, system or space must consider the physical, mental and psychological traits of its intended users. Moreover, the results of the design process are also defined by the attributes related to the context. However, current product design approaches does not offer a proper balance among the “human”, “artefact” and “context” dimensions. Consequently, a product design methodology that covers the overall Human-Artefact-Context system, from a cognitive and physical ergonomics point of view, is proposed. The generalization of the proposal is based on a synergic structure of User-Centered Design methodologies and ergonomic criteria that prevails throughout the product development stages. The latter ensures a better adaptation to specific context and user needs in a way that improves efficiency, security and consumer well-being. © 2015, Springer-Verlag France. more...

- Abstract
In the case of solar vehicles, since the primary necessity is to optimise the energy efficiency during motion, many efforts are addressed by designers in searching the perfect aerodynamics. It means, in particular, the minimization of the drag force at cruising speeds and an elaborated vehicle’s Computer-Aided Design (CAD) are the principal result of this activity. Despite, these efforts can be nullified by geometrical tolerances emerging from manufacturing. In this paper, the effects of tolerances introduced by composite manufacturing processes are investigated combining 3D scanning technology and Computational Fluid Dynamics (CFD). After the solar car manufacturing, a reverse engineering process is executed with the aim to scan the vehicle’s body and compare it to the initial theoretical design. Geometric deviations are found and their aerodynamic consequences are evaluated in terms of aerodynamic losses. © Springer International Publishing AG 2017. more...

- Abstract
The need for more flexible tools and reduction of time and cost has led to the implementation of augmented reality (AR) and virtual reality (VR) techniques in the product design and development process. Those techniques have already been used in the conceptual, manufacturing and assembly stages of product design instead of or in extension of the physical prototypes. Such virtual applications have demonstrated superior performance in assembly process design and evaluation of activities that present information about different assembly states in real time, thanks to their flexibility in manipulating and creating new working scenarios. Here, the development of an AR application, called PoliART, aimed at the visual evaluation of assembly sequences at early stages of design is presented. At an industrial level this allows collaborative work between designers and manufacturing engineers from the very beginning in order to consider assembly devices, times and resources, with a short implementation time and reduced costs. © 2016 Inderscience Enterprises Ltd. more...
