reinvented the wheel

Solved something solved

Reinvented the wheel means wasted effort creating something that already exists in adequate form.

The phrase is almost always critical: We don't need to reinvent the wheel—just use the existing template.

Someone who reinvents the wheel ignores available solutions to solve a problem that's already been solved.

Occasionally used positively when genuine innovation improves on the original.
