I 产品造型创新设计的可行性理论模型建立与分析 Abstract The 21st century is a century of innovation. The innovation of product form design is popular in the scope of industrial design. But seldom people research on the methods and evaluation of the innovation of design as well on the methods and evaluation of the innovation of the product form design. The innovation of product form design deal with the innovation of the appearance of the product. This paper analysis the innovative methods of the product form design on the basis of study on the TRIZ innovation theory. Moreover a comprehensive and feasible innovation model system is established. First, the concept of the feasible theory model of the innovative design of the product form is brought forward. And analysis the relationship of the feasible theory model and the innovative design of the product form on the basis of the relationship between the material and the field in the TRIZ theory. On the basis of conflicts solution theory this paper brings forward the three basic conflicts in the product form innovative design. With bination of the very three basic conflict theoretical models, a more objective analysis system has been established. This paper finally has verified the feasibility of the theoretical mode with a essful digital product as the example.
