Definition from http://www.triz40.com/aff_Principles_TRIZ.php

If it will be necessary to do an action with both harmful and useful effects, this action should be replaced with anti-actions to control harmful effects. • Buffer a solution to prevent harm from extremes of pH.

Create beforehand stresses in an object that will oppose known undesirable working stresses later on. • Pre-stress rebar before pouring concrete. • Masking anything before harmful exposure: Use a lead apron on parts of the body not being exposed to X-rays. Use masking tape to protect the part of an object not being painted

This principle is proposed to solve the following contradictions: 2/325/276/47/148/1410/310/711/1412/1513/1414/614/815/317/317/419/1420/222/227/329/232/3434/934/1436/3337/2538/15
