TRIZ For Dummies Quotes

“Two types of contradiction exist – technical and physical: A Technical Contradiction is when, as you improve something, something else gets worse. You start with a solution but when you put it into practice, you find a downside. For example, you make a car safer by using lots more material but it makes the car heavier. A Physical Contradiction is when you want opposites of the same thing, like an umbrella needing to be both big and small.”
