Can a piece of equipment apply for an invention patent with the same function as others, but completely different in structure and principle?

1, function 100% are all the same, but the structure and principle are different, so you can apply for a patent. Because the function of 100% is the same, it is not the basis for judging the creativity of the invention.

2. If the structure and principle of the invention in 9 1 are different from those in 78, and it will not bring technical enlightenment to the technicians in this field, then the invention is creative and will not be deemed invalid.
