Think you got it wrong. Its not they can't revent the wheel. But they use it to say its just a repeat of something that is already there.
But to answer how many types of wheel like gear wheel , axle wheel serving different purposes .. and there is also air wheel in hoovercrafts ,
The phrase "reinvent the wheel" is an idiom that means to waste time trying to do something that has already been done. It can also mean to try to solve a problem that has already been solved.
