摘　　要：针对牛奶厂人工搅拌不均匀、不充分的问题,应用TRIZ(theory of inventive problem solving)理论对整个储奶罐系统进行创新性设计。通过分析组件间相互作用,得出人工使用铁耙搅拌牛奶作用不足的结论;针对搅拌装置在工作时因高度不同而弯曲程度不同,运用物理矛盾分析,结合时间分离中的发明原理——动态特性,设计出一种电机驱动式、可伸缩的柔性机构。运用solidworks三维软件搭建具体的打耙机构模型,通过试验验证柔性臂工作的可行性。试验结果表明,该柔性臂能完成压缩、伸长、弯曲、扭转等姿态,可实现较大范围的搅拌。The TRIZ（theory of inventive problem solving）helped to solve the innovative design of the entire tank system.Through the analysis of the interaction between components,the conclusion was drawn that the use of artificially stirred iron ladles to agitate milk was insufficient.Using physical contradiction analysis,according to the degree of bending of the stirring device due to different heights during operation the dynamic characteristics A motor-driven,retractable and flexible mechanism was designed.The solid works of threedimensional software was used to build a specific snoring mechanism model,and the feasibility of the flexible arm work was verified through experiments.The test results showed that the flexible arm could complete the compression,elongation,bending,twisting and other gestures,and achieve a wider range of agitation.
