Product Innovation Design Method Based on Case Reasoning

In order to coordinate the product innovation design method and the market economy benefit, it is necessary fully inherited the advantages of similar products. According to the product innovation design theory of evolution, and the thought of case-based reasoning and cognitive psychology, it is analyzed product case information based on the theory of CBR; it is summed up the model of mechanical and electronic products innovation design method synthetically. It is presented the practical method of modeling innovative design of mechanical and electronic products and computer aided technology. It contains the innovation questions, the solving process of industrial design framework and context reasoning model. Taking the CNC machine tool as the object, the model from the situation and three aspects of knowledge expression, is build a preliminary case based on computer aided industrial design system, and it is applied to the design practice. The actual show that the method is in conformity with the world's innovation
