Product architecture is a method to translate the physical element of the functional requirement within the product system and describe the connection between these physical elements. Physical element will be interpreted through parts, component or subassemblies. Method of product architecture is an effective way in determined the conceptual design because it is not only considered the way of the product to be designed but it also focused on how the product will be made, used and even maintaining the product. This paper presents the methodology of the design and development of mini hydrogen cell for petrol powered internal combustion engine through the product architecture method. This method is applied based on the four stages of the product concept development process which is product element, product cluster, product geometry and the morphological chart. From this method, the best option of the concept is selected.

Companies worldwide are striving to reduce the costs of their products to impact their bottom line profitability. When it comes to improving profits, there are in two choices: sell more or cut the cost of what is currently being sold. Given the depressed economy of the last several years, the “sell more” option, in many cases, has been taken off the table. As a result, cost cutting is often the most effective path. One of the industrial challenges is to search for the shorten product development and lower manufacturing cost especially in the early stage of designing the product. Knowledge-based system is used to assist the industry when the expert is not available and to keep the expertise within the company. The application of knowledge-based system will enable the standardization and accuracy of the assembly process. For this purpose, a knowledge-based design for assemble system is developed to assist the industry to plan the assembly process of the vehicle seat.
