介绍了类比源设计与功能类比作用原理,从两者作用原理及发明问题求解理论(Theory of inventive problem solving,TRIZ)的相关性描述得到启发,提出基于TRIZ的类比源设计求解过程模型。首先,借助于所建立的产品功能结构模型,找出用户需求与产品各功能之间的关联性。其次,将用户需求权重值赋予相关的产品各分功能,从而得到产品功能相似度矩阵,再利用Matlab工具对该矩阵进行标准化,这有利于类比源设计与待设计问题之间相关性的定量化表示。最后,构建出一种基于TRIZ及功能类比的概念设计过程模型。以紫外光油烟净化机为例,对其功能类比源设计的功能相似度进行分析,并利用有效价值分析法对所获得的功能原理解方案进行评价,验证了所构建模型的正确性。
The principle of analogy source design and functional analogy is introduced, and inspired by the connection between analogy design principle and TRIZ tools, the source design of function analogy process model based on TRIZ is established. Firstly, the relationship between user requirements and each function is obtained using function structure model. The related product function is endowed with the weight value of user requirements, and the functional similarity matrix constructed is standardized by Matlab tools. So the quantitative correlation between the source design and design problems is represented in the matrix. Finally, the process model of conceptual design based on TRIZ and function analogy is established. Functional similarity of the UV fume purifying machine and functional analogy source design is analyzed. Moreover, the obtained functional principle solution is evaluated by effective value analysis to validate the correctness of the model.
