针对采煤机生产率方面的需求,把工程问题在功能层面上定位于螺旋滚筒,利用TRIZ组件模型、结构模型和功能关联模型分别表明机械结构组件构成、组件间的相互作用及组件间是有害作用还是有用作用。分析了工程问题形成的根本原因,利用TRIZ进行了原理方案求解,证明了TRIZ理论在求解工程问题上的有效性。 According to the demand of shearer productivity, the engineering problem is located on the spiral drum at the functional level. The use of the TRIZ component model, the structural model and the functional correlation model respectively indicate that the mechanical component components, the component interactions and the component components are harmful Still useful. The root causes of engineering problems are analyzed, the principle scheme is solved by using TRIZ, and the validity of TRIZ theory in solving engineering problems is proved.
