Abstract: To satisfy diversified product requirements and deal with the problem of a wide range of product portfolio generated in design process of industrial design, an ontology-based approach of product family design DNA in industrial design was proposed. The concepts of industrial design ontology and product family design DNA were studied. The product family ontology knowledge of industrial design, the inheritance and variation rules of product family design DNA, research flow and key technologies were analyzed. The product family ontology knowledge representation model, and the inheritance and variation of product family design DNA model were put forward. Taken the glasses form design as an example, the ontology-based glasses product family DNA configuration model and a three-dimension computer-aided design system software of glasses form were set up. Based on the system, the glasses design could be accomplished efficiently, users'perceptual image and form could be mapped, and the ontology-based product family design DNA theory in industrial design was also tested.
