This is Folding-Plug. When folded, the folding plug will take up less space than traditional plug. Of course, it’s just one of the features of plug. If you’re curious, let’s go on checking.
Folding-Plug is an innovative and functional design concept designed by three designers: Huang Guanglei, Wei Min and Jiang Zhongbiao. As we can see from the images, the plug consists of a plug head and a plug board. When folded 90-degree, the plug board will attach to the wall outlet in order to save space, most importantly, the built-in switch will be on so that you can activate your device. When you lever it 90-degree perpendicular upwards, the circuit will get off in order to protect the connected device from the surge current and save power.
Unfortunately, Folding-Plug is still a design concept. We have no idea whether the practical design concept will become reality. Additionally, here is another wonderful plug themed design concept.
