基于发明问题解决理论的系统设计方法应用

Application of systematic design approach based on theory of inventive problem solving

针对从发明问题解决理论(TRIZ)解场中选择较优解困难,而系统化设计方法的创新原理解产生过程具有随机性的特点,通过在TRIZ中引入系统设计方法,提出一种将两者在方案设计解场精简阶段进行集成的创新设计过程模型,实现了系统化设计方法对TRIZ解场的精简,优化了解的获取;同时TRIZ作为一种方便快捷获得解场的手段弥补了系统设计方法过程中解场的产生缺乏有效工具的缺陷.以汽车油箱贮量测定仪传感器设计原理解场的提出与精简为例,表明了该过程具有良好的可操作性、方法工具组合的灵活性,以及考虑产品后续设计的系统性等优点.

The theory of inventive problem solving（TRIZ） is hard to choose better solutions, and the systematic approach has a little randomicity on the generation phase of creative solutions. A new idea was presented by using the method of selecting solution variants in systematic approach on dealing with solution sets of TRIZ, and an integrative innovation design process model was proposed. Then TRIZ and systematic approach can complement each other. From the system viewpoint, solutions were obtained faster and easier, and the systematic approach decreased the amount of solution sets of TRIZ in order to make the designing decision accurately and efficiently. The process of solution sets selection on designing fuel gauge was taken as an example. The process has good maneuverability and flexibility of methods and tools, and considers the systematicness for following phases of designing process etc.
