Design of folding mechanism of camping stroller based on extension innovation method and TRIZ theory

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.
