Apparently it’s not very easy for us to insert a plug into plug socket in the dark, so talented designer came up with the plug socket design concept: Donut. If you’re curious, let’s go on checking.
The Donut is a very practical socket design concept designed by three South Korean designers, including Suhyun Yoo, Eunah Kim and Jinwoo Chae. As we can see from the images, the traditional plug socket with two holes has been replaced by a unique socket. There is no any small hole but a ring-shaped “hole” on the socket. No doubt, you will never worry the two pins of your plug doesn’t align with ring-shaped “hole”, even in the dark. After the break, check out the images about the plug socket design concept.
