Table 9.1 Thirty-nine Parameters

1. Weight of moving object 21. Power
2. Weight of nonmoving object 22. Waste of energy

3. Length of moving object 23. Waste of substance
4. Length of nonmoving object 24. Loss of information
5. Area of moving object 25. Waste of time

6. Area of nonmoving object 26. Amount of substance
7. Volume of moving object 27. Reliability
8. Volume of nonmoving object 28. Accuracy of measurement

9. Speed 29. Accuracy of manufacturing
10. Force 30. Harmful factors acting on object
11. Tension, pressure 31. Harmful side effects

12. Shape 32. Manufacturability

will be raised to a whole new level. TRIZ developed many tools for elim-
ination of technical contradictions.

Physical Contradiction
A physical contradiction is a situation where a subject or an object has to be
in a mutually exclusive physical state. A physical contradiction has the
typical pattern: To perform function F , the element must have property P,
