1. reinventing the wheel​Idiomatic expression
Wikipedia definition
2. Reinventing the wheel​To reinvent the wheel is to duplicate a basic method that has already previously been created or optimized by others. The inspiration for this idiomatic metaphor lies in the fact that the wheel is the archetype of human ingenuity, both by virtue of the added power and flexibility it affords its users, and also in the ancient origins which allow it to underlie much, if not all, of modern technology.
