摘要: 针对经典TRIZ理论工具解决复杂产品中多冲突问题具有的局限性,强势思维一般理论(General theory of powerful thinking,OTSM)主要解决复杂跨学科创新性问题并进行一般化的表达,但没有明确给出消除多冲突及寻求最优解决路径的一般方法。通过对复杂产品构建问题流网,从中选取关键问题,进而转化成冲突网,然后对其中的关键冲突进行判别并转化成参数网,应用TRIZ工具进行冲突解决并提出解决方案,提出了关键问题的判别方法和关键冲突网到参数网的转化规则,给出了问题流网、冲突网及参数网的构建过程,最终建立了面向复杂产品的问题流网络构建与求解过程模型。以工程机械900吨架桥机作为实例进行创新设计,验证了该过程模型的有效性。

Abstract: Against the limitations of the classical TRIZ theory tool to solve multi-conflict problems in complex products, OTSM theory (general theory of powerful thinking) mainly deals with complex interdisciplinary innovative problems and gives generalized expressions, but without clearly providing the general ways to eliminate multiple contradictions and search for the optimal solution path. Based on the construction of the problem flow net for complex products, key problems are selected from it, and further transformed into the conflict net, and then the key conflicts are discriminated and transformed into the parameter net. Meanwhile, TRIZ tool is applied to resolve the conflicts and put forward solutions, and the discriminative approach for key problems and the transformation rule from key conflict net to parameter net are proposed. Then the construction processes of problem net, conflict net and parameter net are provided. Finally, the problem flow net complex-product-oriented and the solving process model are established. Moreover, the 900T bridge erecting machine for construction machinery is taken as an example to conduct innovative design, having verified the validity of the process model.

Key words: bridge erecting machine, multi-contradiction, OTSM, problem flow network, TRIZ
