Abstract: Determination of specification for product development is useful, as it includes an overview of product-related information. However, it is not an easy thing, especially for new and innovative product. In the view of designer as the subject who has never made the product, he needs to work closely with the manufacturer so that the concept can be designed to become a feasible product. In addition, in order to reduce product design life cycle and minimize design errors, the designer needs to communicate and collaborate with the manufacturer. This research proposes a design specification based on the paradigm of Concurrent Engineering (CE) from Collaborative Product Development (CPD) strategy in the development of a new ergonomically designed Short Wheel Base (SWB) Recumbent Bicycle. This collaborative process involved an expert from bicycle practitioner which already had experience in building custom bicycle. The result of this study is a frame set design of the bicycle which considers human anthropometry and the detail list of its components. Beside of that, the process of collaboration with practitioners bicycle produces 37% change in the components used and 3 changes in shape of design SWB Recumbent Bicycle.

Abstract: Due to the product complexity and time constraint, it is common to conduct a collaborative design process to consider design requirements concurrently from the product lifecycle. However, such multi-disciplinary integration process may lead to potential design conflicts which has to be further resolved as the development continues. In this research, we propose a novel analytic model by combining the concepts of Ideal Final Result (IFR) and Trends analysis in TRIZ theory to systematically find the possible design contradictions from a top-down approach. The IFR is used to represent the integration of the developing product requirements which are requested from the collaborative team members. We then apply Trends analysis to compare the current state of existing product and the IFR state of the developing product. Therefore after comparison we will transform the differences into 39 engineering parameters defined in TRIZ to acquire possible design contradictions among components. The contributions of this methodology not only derive design conflicts systematically, but also help designers jump out of their psychological inertia and perform the design process with IFR to achieve distinct innovation.

Abstract: Collaborative product design is a multiple criteria group decision making process bringing different and often controversial points of view together to create a solution among stakeholders. Collaborative design possesses more perspectives than any single person possesses because stakeholders have different perspectives. This work is based on new decision approach that includes creating shared understanding among various stakeholders, contextualizing design criteria and perspectives, and creating a multiple perspective and multiple criteria decision approach, our initial effort has focused on incorporating perspectives into design process. We then provide the approach to find the optimal design decisions for consideration of stakeholders’ perspectives. By analyzing the relationships between stakeholders’ perspectives and preferences of design criteria, multi-criteria decision making approach considering the stakeholders’ perspectives can be used to monitor and control the collaborative design process.

Abstract: Collaborative product design is a complex and time-consuming process whereby geographically distributed designers from different disciplines cooperate and collaborate. Well-studied collaborative product design system reduces development time and creates better products. This paper discusses the characteristics of collaborative product design based on multi-agent technology to minimize the development time, cost and risk. In particular, the proposed agents can provide the interaction spaces for coordinating the individual design activities. Furthermore, the mechanism of intercommunications between agents is discussed. This research work constitutes initial effort towards optimization of process of collaborative product design. Future effort will focus on the software implementation of the theory presented in this paper.
