Product optimization design method combined with extenics based on TRIZ

Abstract

A product optimization and design method combined with extenics based on TRIZ comprises: A) analyzing product to find out the technical conflict or un-technical conflict which obstacles the product technical performance; B) if the conflict which obstacles the product technical performance is a technical conflict, using the TRIZ conflict matrix to obtain a preliminary scheme to solve the technical conflict; C) entering an extenics diverging tree process, using the diverging tree method to obtain a diverged schemes set (shown on right); D) entering the diverged schemes converging process, that is, performing extenics goodness estimation to the diverging schemes set obtained in the step C) by the goodness grading method to obtain a goodness sequence about the diverged schemes, selecting the scheme with the highest goodness value as the optimal preferred scheme, and entering into policy making and implementing step; B) if the conflict which obstacles the product technical performance is an un-technical conflict, entering the step C) directly, and finally entering the step D). The invention can be widely used in the development and design of various industrial products.

Description

technical field [0001] The invention relates to a product optimization design method based on the combination of TRIZ and extenics. T&E method for short, including TRIZ contradiction analysis matrix, which is used to solve the technical contradictions hindering product innovation; extension tree method, which is used to obtain multiple divergent innovation solutions; superiority evaluation method, which is used to obtain the final optimal solution. Background technique [0002] TRIZ theory is the Russian synonym of TIPS (Theory of Inventive Problem Solving). It was a Soviet inventor G Altshuller who analyzed and studied more than 400,000 patents, and in 1946 proposed an innovative principle solution called TRIZ. The most important thing in TRIZ is to establish a corresponding relationship between the contradictions of these engineering parameters and the invention principles according to the 40 invention principles with universal application and the 39 general engineering p...

Problems solved by technology

[0006] If the TRIZ method is used alone, it can solve the technical contradictions that hinder product innovation and optimization, and obtain the product innovation optimization plan; if the extenics method is used alone, it can solve the technical contradictions of products caused by non-technical problems, although both can solve product optimization. However, since the TRIZ method and the Extenics method have different focuses on guiding innovation, it is inevitable that product design and manufacturing optimization will not be comprehensive, which will affect the final product optimization results and lead to various quality or humanized use problems of the product.
