机械功能分类和功能设计模型

Mechanical function taxonomy and the function design model

在机械创新设计中 ,功能既是对产品的认识 ,又是创造的基础 ,功能描述需要兼容具体化和抽象化 .文中从机械功能设计本质特征出发 ,探讨了功能设计内涵和功能分类方法 ,将机械功能分为产品功能和基本机械功能两类 .从创造性思维模式出发 ,将功能设计过程分为功能辨识和功能抽象两个阶段 ,提出了基于机械功能分类的功能设计模型 .该模型既强调了功能设计的本质是对设计问题的认识 ,又符合设计者认识问题从具体到抽象的设计思维 。

In the mechanical creative design, by function is meant the understanding of the product as well as the basis of creation. Function description must have both concreteness and abstraction at the same time. Based on the character of the mechanical function design, this paper discusses the implication for function design and the method for function taxonomy, and divides mechanical function into product function and fundamental mechanical function. On the basis of the creative thinking pattern, the function design process is divided into function identification and function abstraction. Also a function design model based on function taxonomy is proposed, which emphasizes the fact that the character of function design is the understanding of the design problem, and makes it satisfy the needs of the design thinking pattern from concreteness to abstraction when a designer understands a design problem. Also it provides an implementation framework for CAD to support the function design.
