| Product innovation is the survival and developing foundation of the corporation. Being the main part of enterprise innovation system, product innovation needs scientific theory and method. As the core of product innovation, conceptual design is paid more attention. TRIZ (Theory of Inventive Problem Solving)is a kind of very important theories in the conceptual design method. TRIZ is a theory about invention and concept. It is an integrated theory composed of all kinds of methods for solving technical problem and innovative development and arithmetic. It has provided a series of tools for engineering problems, such as inventive principles, separation principles, standard solutions and effects database.In this paper, the TRIZ theory and the application in product innovation is studied. The following works are covered:1. Based on analysis of the basic principles, general solution approach and process of TRIZ, the approach and method of product innovation using technology evolution, conflict resolve theories, effects database of TRIZ is studied.2. According to the simulation that we can't confirm the contradictions in the application of TRIZ theory, a new method for no-contradictions-product was put forward, furthermore, the innovation principle table of improvement for the specified engineering characteristics was introduced.3. Based on the computer aided-inventive design software TechOptimizer, an innovation process for no-contradiction product was put forward. It includes establishing the product basic functions module, putting forward the innovation concepts in use of ABC, expressing the innovation concepts, integrating the basic and innovation functions, evaluating and trimming the system models. At last, the concept design of the new product is generated.Finally, with an example the feasibility was proved, and a new problem solving method is provided for product design. |
