| Summary: | 碩士 === 國立成功大學 === 工業設計學系 === 87 === In the conceptual design phrase, designers must transfer users'' requirements to some viewpoints and concepts of themselves. In this process, because the primary problems encountered may be very complex and cant not be solved immediately. So, some systematic design methods tell us to decompose the big problem into several small problems. And then figure out possible solutions through them.In product concepts, designers usually think by the functions of the product as the regards of design problems. So, some researchers mentioned about some ways to establish function structure and decompose functions. In other words, to find out design solutions, designers have their own ways decompose functions in design process.Design representation research occurred in order to understand the nature and origin of design fully. This thesis includes design object representation and design process representation, and this article aimed at the input and output information of conceptual design phrase and introduced a design representation toward problem decomposition.Functions and solution principles are defined by functional decomposition in this research. And Some rules are created to guide the design''s function decompose process. By this knowledge infrastructure, we hope to clarify the black box of the design activity and assist designers to configure functions and search solutions.
