Method and application based on extension and TRIZ theory for disassembly structure design

Design for Disassembly(DFD),which is one of the main content and key technology of green design is an effective means to ensure product structure to be easy to assembly,disassembly and maintain.Further more,DFD is an inevitable choice to make the reusable parts of waste products be fully and effectively recovered reused so as to save resources energy,and protect the environment.To achieve product disassembly design,a new disassembly design method based on theory of extension and theory of inventive problem solving(TRIZ)was put forward,in which relationship element of product is firstly determined by base-element theory of TRIZ.And then the contradiction is obtained in product disassembly design by matter-element transformation.In addition the contradiction matrix of TRIZ is applied to solve the problem,achieve the goals of design.Finally,the validity and efficiency of the method is rectified through experiments.
