Construction and Application of Product Fast Conceptual Design Knowledge Base Based on Configuration Flow Graph

Abstract

Complex and diverse product information and rapidly-iterated market competition context are common in the current product design areas. The rapid concept design of products is becoming a major challenge for product designers and enterprise R&D departments. Utilizing the design knowledge of 100 common products selected in the market, this study divides and realizes structured storage by function in the form of CFG matrix by introducing standard functions, components and flow lexicon. For application of matrix library, this paper proposes a template CFG search method based on similarity calculation to assist designers in implementing rapid conceptual design. Bicycle is exampled to verify the practicality of the constructed matrix library and the effectiveness of the proposed method.
