Incorporating Simplification and Solution Strategies of Multi-conflict Network in TRIZ and Extenics
In order to solve the problems of high functional complexity of product systems and te-dious conflict solving processes,the strategies for simplifying and solving multi-conflict networks were investigated herein.Firstly,the conflicts were described by using the extensible basic element models,and a multi-conflict network was constructed by using the causal analysis methods based on functional models.In order to identify key conflicts the techniques for order preference by similarity to ideal solution(TOPSIS)methods were applied to establish a comprehensive evaluation system from the perspectives of the topological characteristics of conflicts in the network and the degree of customer requirements.Secondly,a method for decomposing key sub-conflict networks was proposed to extract conflicts related to key conflicts and form sub-conflict networks.Finally,a set of rules for simplifying multi-conflict networks was proposed,which utilized extensible transformations to eliminate the rela-tionships between conflicts.The simplified sub-conflict networks were then integrated,and the TRIZ tool was used to solve the key conflicts,so as to put forward a strategy for simplifying and solving multi-conflict networks.The feasibility and effectiveness of this strategy were demonstrated through the analysis of an intelligent stair-climbing wheelchair as an example.
