Abstract TRIZ theory utilizes 40 inventive principles to solve contradiction and its inventive principles have universality. To guide electrical creative design, on the basis of summarizing electrical design regulation, a great deal of design examples are sieved according to the later 20 inventive principles of the 40 TRIZ inventive principles. It enriches the engineering design database of inventive principles in TRIZ and offers inventive principle references on solving contradiction in electrical design for designers.

电气设计中的发明原理分类研究——发明原理之No.21至No.40
TRIZ理论用40条发明原理来解决冲突，其发明原理具有普遍性。为指导电气创新设计，在总结电气设计规律的基础上，对大量设计实例进行筛选，将部分典型实例按TRIZ 40条发明原理的后20条原理进行分类，进一步丰富了TRIZ中发明原理的工程设计实例库，并为解决电气设计中的冲突问题提供发明原理参考。
