摘要
矛盾矩阵和理想度都是TRIZ理论中非常重要的概念。一般地,理想度被定义为有用功能与有害功能的比值,但是对于功能的定义与划分并不一致。论文借用矛盾矩阵中的48个工程参数对功能进行了新的界定,给出了技术系统理想度的判定公式,结合双环拱形分体式立体轿厢旋转立体车库的设计进行了具体的说明。为了便于合理评价技术系统,文中比较了理想度、性价比和价值。
Contradictory matrix and Ideality are the important concepts of TRIZ. Ideality is generally defined as the specific value of useful function and harmful function. However the definition and classification of function is not definite. This paper redefines function using the 48 engineering parameters of contradictory matrix, and provides the formula of calculating ideality. Then it gives the specific example to explain the new method of defining ideality. In or- der to facilitate the reasonable evaluation system, this paper compared the three different of the ideality, performance- to-price ratio, and the value.
