Let’s assume a mechanic wants to repair a motorbike and disassembles it. Once the broken part is located, he needs to find out the part number for the reorder. But maybe the part is covered in dirt or has no imprinted number at all. Wouldn’t it be great to recognize the part by its shape?
A more sophisticated future version of the prototype could present the user with several products to choose from, in case the one linked to a certain shape has several variants (e.g. colors).
