"The phrase is sometimes used without derision, when a person's activities might be perceived as merely reinventing the wheel, when they actually possess additional value. For example, "reinventing the wheel" is an important tool in the instruction of complex ideas. Rather than providing students simply with a list of known facts and techniques and expecting them to incorporate these ideas perfectly and rapidly, the instructor instead will build up the material anew, leaving the student to work out those key steps which embody the reasoning characteristic of the field." -wikipedia bro
I like to think a HCDE student spent her entire winter quarter designing a bottle cage and 3D printing it. She got an A- on the project then took it over to Recycled Cycles and got $5 store credit for it. The next day I picked it up and took a photo then chucked it back in the bucket and bought two Profile Design cages in pristine condition for less than half the price of her big project.
