A patent issued this week for an origami urinal designed to address the plight, lovingly illustrated, of the boy who is too short for a standard urinal.
The patent (8,117,681) describes a folding cardboard urinal that can be hooked onto the edge of an existing urinal to provide a lower target.
After use, it is tilted backward to empty its contents. The urinal is cleverly constructed out of a single sheet of cardboard. Until it is needed, it folds flat for convenient storage.
