Design Clamping Device of Milling Fixture Base on Contradiction Matrix

摘要

TRIZ is one of the most important tool for innovative design. But the theory that how to use the tools of TRIZ to solve problems isn't mature. So, this paper puts forward a method, which introduces how to use contradiction matrix to solve problems that we meet when we design products. Firstly, we should make sure ideal final result (IFR) of products and find the problems of the products by the IFR, then compare the problems with engineering parameters and be sure deteriorative engineering parameters of the products. Secondly, find technical contradictions of the products by proposing conventional methods which we can use to deal with the problem obviously. Thirdly, seek contradiction matrix table and find the inventive principles according to the technical contradictions. Finally, translate the inventive principles to specific design ideas. In the end, this paper use design of clamping device in milling fixture as an example.
