摘　　要：针对卡车座椅高调锁止装置档位间距过大的问题,首先应用IFR原理分析高调锁止装置存在的必要性,然后应用系统功能分析及裁剪、因果分析等TRIZ工具,深入的理解问题产生的根本原因,并运用冲突分析、物-场分析、进化分析等TRIZ工具,形成了13个方案。最终对所得方案进行评价,根据实际需求选择了用气撑调节并锁止、用气缸调节并锁止、复制限位孔及限位销等三个方案,优化了锁止装置,在保证强度的同时,减小了档位间距。Aiming at a spacing issue of truck seat height adjuster,firstly IFR is applied to analyze the necessary of the truck seat height adjuster locking system.Secondly,Analyze and Cut System,and Cause-Effect Chain are used to expose the function of the system and the root cause of the issue.And then Conflict Analysis,Object Field and Evolution Analysis are used to get thirteen optimized proposals.Eventually,according to the requirements three proposals are confirmed.As a result,the optimized locking system by applying TRIZ tools performs well both at strength and spacing.
