面向新产品概念设计优化的裁剪方法研究

摘要

A method of analyzing and solving problems in TRIZ theory,and trimming can simplify the structure of the system,reduce the cost,effectively optimize the system problems,and improve the efficiency of innovation.In order to optimize design process of new product concept and improve the quality of products,the thought of trimming was brought into the process of new product concept design process,one extended failure prediction (AFD-2) was used to determine the trimming key issues of new product concept design optimization.Then based on the key trimming problem in the system,the functional model was built and the trimming elements was determined the process model of trimming innovation design oriented was contructed to new product concept optimization.The trimming example of bridge machine concept design verifies the rationality of this method.%裁剪作为TRIZ理论中分析、解决问题的方法,其可简化系统结构、降低成本;同时可以有效优化系统问题,提高创新效率.为优化新产品概念设计方案、提高产品质量,应用扩展的失效预测(AFD-2)方法确定面向新产品概念设计优化的裁剪关键问题,基于所确定的裁剪关键问题辅助建立系统功能模型,进而确定裁剪元件,对系统进行裁剪,构建了面向新产品概念设计优化的裁剪创新设计过程模型.最后通过架桥机的裁剪实例验证了此方法的合理性.
