Abstract: The method of building knowledge map for industrial design process is proposed to organize the industrial design knowledge, which can add innovations of product concept design. By the investigation on the industrial design process, the design process descriptive model with different abstract granularity levels is established, which forms the frame of knowledge map. Based on the concepts system of knowledge node, the structure of input and output are defined. The design knowledge can be acquired, saved and reused in the uniform by the operation of combination, decomposition, derivation, insertion and trim. On the one hand, knowledge can be organized by knowledge map with the operation procedure, which can reduce the chaos of knowledge complexity, distraction and obscurity, and help to make the design decisions and ideas. On the other hand, visible knowledge map can be adapted to some kinds of design projects, and integrated with the design knowledge scenario information of condition, object, procedure, cause and effect, which can reduce the blindness of design activities with single knowledge area. An application case is introduced to prove the method.
