A Product Concept Method for Industrial Design based on Basic-element model

Taking basic element model as a breakthrough perspective for Conceptual Design, ways to merge Extenics into industrial design are studied. A clear conception method was proposed in terms of divergent thinking-guided methods, constructed by three points, Special features, Special magnitude, and Special rules. "The multifunction chairs" were used to illustrate the Special rules application. This paper describes a new perspective for the analysis of the creative ideas. Formalized model, different from the past art theory researching, it was verified the effectiveness, practicality and innovativeness.
