Study of product design DNA based on shape perception

To satisfy users´ diversified requirements, the concept of product design DNA was proposed and became a hot research topic in industrial design. In this experimental study an approach of shape perception is proposed to extract the product design DNA; the relation between shape perception and product design DNA is explored. Taken the gas-cooker´s shape design as an example, the novel approaches, cluster analysis and semantic differential (SD) method, were employed. Then four design elements (DNA) of designers´ shape perception are explored; the weight factors of these elements are obtained; thereby providing a certain methodology direction for the extraction of product design DNA and for the combination between designers´ shape perception and product design DNA in the product design.
