摘　　要：针对营地手推车现有折叠方式效率较低、产品笨重等问题,综合利用多种折叠方式以解决现有问题。首先对现有营地手推车的折叠结构进行分析,确定待解决问题,其次依据基元理论创建问题模型,利用TRIZ理论查询并确定解决相应问题的发明原理,再进行拓展分析和可拓变换,得到解决方案,最终借助优度评价选择最优方案。通过营地手推车的实例设计,实现对其折叠时间、折叠流程以及轻量化的目标问题优化,证明可拓分析与TRIZ中发明问题解决原理相结合能够提高解决效率,为以后产品创新和筛选方案提供参考。Aiming at the problems of low folding efficiency and clumsiness in the existing folding methods of camping stroller,various folding methods were comprehensively employed to address them.First,based on the analysis of the folding structure of the existing camping stroller,the problem to be solved were identified.Second,a problem model was established based on the primitive theory,and the TRIZ theory was adopted to query and determine the invention problem solving principle to solve the corresponding problem,and expand it with extension.The transformation was analyzed and extended to obtain a solution,and finally the best solution was selected with the help of superiority evaluation.Through the example design of the camping stroller,the optimization was realized in terms of its folding time,folding process,and lightweight target problems,and it was proved that the combination of extension analysis and the invention problem solving principle in TRIZ can improve the problem solving efficiency and provide reference for future product innovation and screening solutions.
