Drain cover for women's sake

Why is he thinking about women? The reason is that men don't wear high heels. Haha. A girl in a high heel definitely walks around a sewer with a floor drain. Because he's afraid the lid will eat their heels. Yan-Ting Chen & Hsin Yeh came up with this clever idea, just turn the direction of the leak lid a little bit, which is quite thoughtful, because it can not only prevent the heel from entering, but also effectively block the volume of garbage that should not enter, so that the sewer is always unblocked. The idea is just a little bit different. This design was also the winner of the 2010IF Concept Design Award.
