文摘为解决现有儿童乘车约束系统的使用率低和误用率高等问题,基于用户需求对集成式儿童安全座椅进行创新设计。基于层次分析法(Analytic Hierarchy Process,AHP)进行用户需求研究,搭建基于文献和用户访谈的集成式儿童安全座椅用户需求层次模型,并计算出各项用户需求要素的权重和排序,确定设计过程中有待解决的重点问题。基于质量功能展开法(Quality Function Deployment,QFD)构建反映用户需求与设计要素关联性的质量屋模型,计算出设计要素的综合权重和排序。基于TRIZ理论,结合设计需求权重,对设计要素实现过程中存在的矛盾冲突进行分析,并根据质量屋模型提出集成式儿童安全座椅创新设计方案。
