Concept While getting older and degenerating, the elders probably can’t move their arm easily. Therefore, it is often uncomfortable and inconvenient while they trying to take off their outer garments such as coats or shirts alone. For this situation, we design a clip which bases on the rotary operation for helping the elders to take off their clothes. And thismight give the elders more independence without getting help from others. In mechanism, we use two circles with different axle centers making the clip be tight after being rotated.
