Where the matrix suggests it
The classic contradiction matrix suggests Composite materials in 95 of its 1,248 filled cells. Most often for these conflicts:
- Improving Area of stationary object worsens Strength
- Improving Area of stationary object worsens Ease of manufacture
- Improving Strength worsens Weight of stationary object
- Improving Shape worsens Reliability
- Improving Stability of the object's composition worsens Object-generated harmful factors
- Improving Strength worsens Area of stationary object
- Improving Strength worsens Ease of operation
- Improving Duration of action by stationary object worsens Length of stationary object
