I have an idea of invention, how to realize it?

The idea itself can be applied for invention, but in the process of putting your idea into practice, there are often a series of new and better ideas that your idea has not involved. If you apply for an invention without authorization, your creativity will become worthless. So it's best to make the real thing yourself, make sure it's feasible, and then apply for an invention patent and find someone to cooperate in production.
