A large umbrella has good rain-proof effect, but it is easy to avoid blowing and difficult to support. How to use conflict resolution matrix TRIZ to solve this problem?

First, define your problem as a technical contradiction with 39 engineering parameters, and then use the conflict matrix to find the applicable innovation principle. If these principles can be used to solve these technical contradictions, you can apply for one or more patents for secondary inventions. If you can find the physical contradiction from the core of these technical contradictions and solve it, you can apply for a higher-level invention patent.

TRIZ theory is the navigator of thinking, and it can't directly provide solutions. If someone uses TRIZ theory to solve your problem, he will apply for a patent. Do you like the ending?
