Principle 34. Rejecting and regenerating parts: You've used it and now you don't need it anymore. Time to discard it, right? But what does that really mean? What do you do with it? You could throw it away, restore it, or recycle it somehow. But whichever approach you use, you're going to need some system to handle all of this. And that's where TRIZ comes in. TRIZ is the next evolutionary step in creating an organized and systematic approach to problem-solving. With TRIZ, you can discard old parts and regenerate new ones more efficiently and effectively than ever before. So why wait? Get on the TRIZ bandwagon today!
