| Summary: | 碩士 === 國立臺北科技大學 === 創新設計研究所 === 94 === In the era of knowledge economy, converting the experiences and technologies of product development into preservable and reusable knowledge can increase the worldwide competitive advantage of an enterprise. However, the design experiences in the mental models of designers are tacit knowledge, which can become explicit knowledge for further applications through systematic methods. The procedure of product development usually starts from determining suitable components that will carry into the product to realize the product function, according to the specification of it. And then, the shape of the product will be designed based on the component placement. Therefore, the components and their placement of the product are the key element of product development. In this research, an approach has been developed to extract the design knowledge from designers’ experience. By the proposed approach, design features can be created in the model of the component with the CAD environment. While design project proceeds, the design feature will be transferred into the relative part of the product automatically. And the geometry of design feature can be modified more flexibly and easily. The design features can be divided into three types: ”Additional feature” is to add material to the part of the product; ”Removed feature” is the removed area from the part; ”Space-limited feature” means to keep an empty space for assembly or product operation space. A practical design project has been implemented to demonstrate the usefulness and effectives of the proposed method. A database will be built and shared with the others, while the design knowledge will be accumulated constantly through product development cycles.
