From the perspective of intellectual property, the idea of invention and creation is also your own intellectual property. You can apply for a patent. The current patent system does not require you to apply for a patent in kind, as long as it is feasible in theory. With a patent, it means that the country has given you certification and recognition, and you have the opportunity to find cooperation, sponsorship and funds with your own ideas. Now there have been many achievements, and the operating agencies are ready to do the same.
Therefore, the premise of realizing the idea is that you have to prove that it can be realized, at least in theory, and you have to protect it before cooperating, otherwise, even if the idea is feasible, it will be used by others.
