3D Knowledge Design System in Product Design

The purpose of the research, driven by shortening of product development cycle and increasing number of new product developments, is to capture design process, knowledge, know-how standardization, knowledge build-up, and to create a system, which enables an inexperienced designer to design a product above acceptance level, in short development cycle. For this purpose, (1) Visualization Analysis was done to define design processes, which are now a tacit knowledge of experienced designer, and to develop a development process based on logical chain of each process, (2) Design know-how, needed for each design process, were defined for inexperienced designers to comprehend and complete their tasks, and (3) defined design process and design know-how from each process was integrated with 3-Dimensional CAD to establish 3D Knowledge Design System. The system has been applied on design of Shock Absorber for cars, for verification. As result from using the system, 92% of 599 processes were able to be completed by young designers. Moreover, young designers were able to complete the design, without any support from skilled designer, and reduce 66.7% of the design time compared with design time without the system.
