This same design concept can be applied in the home to curtain chains, so that if a child should get tangled in one, tugging on it with a force greater than three kilograms (less than the weight of the average infant) the chain will detach, protecting them from accidental injury.
這個設想周到的設計也可以用在家中的窗簾拉繩上，幼兒若不小心被捲到，只要拉扯力量超過幼兒一般體重 3 公斤以上，就會自動斷掉，可以有效防止幼兒發生捲簾意外。
