Abstract: To support product design knowledge resuse, the model of product form design knowledge was proposed to decompose cases and reuse the design knowledge. According to three stages in users'product cognition, aesthetic impression, semantic judgment and symbol association, product form innovation types were classified into formal aesthetics, utilization method and fashion. Based on taxonomy and the design & innovation process of form, the framework models corresponding to innovation design were constructed to extract and reuse the form innovation design knowledge. The model was applied in the product case database, which could help the designers to search and reuse cases so as to realize the user-centered product development. The effectiveness of the database was finally verified.

Key words: industrial design, users cognition, product form, innovation design, design knowledge
