Strange washbasin in Zhangjiajie, China

When I went to Zhangjiajie in China Solicitation of Zhangjiajie in ChinaI was also impressed, but the hotel I stayed in was very cold and the washbasin was unusual.

I tried to fill the sink with water to wash my face, but there was no button to block the drain. Isn't there usually something like a drain button on the front of the sink?

There is no drain button, how do I close the drain?




Press the drain button to close it and press it again to open it. In other words, the opening and closing of the drain hole was designed with a toggle-type interaction design.

It was the first bathroom sink drain I saw.

I finally got water to wash my face, and my wife asked me how to drain the water. It seems that my wife also saw that the drain button was missing. So I'm proud to show you how to block the drain.

However, when I tried to drain the water after washing my face, a problem arose.

To drain the water, you have to press the drain again as mentioned before. However, the sink is full of dirty (?) water after washing, and you have to put your hands in the water.

It would be nice to have something like a wooden stick by my side, but there was none, so I ended up putting my hand in the water to drain the water, then turning it on again to wash my hands.

The toggle method is an interaction design element that can be used when one has two modes, such as on/off. For example, an electrical switch that turns on a light in a room, or a checkbox in Windows or a webpage.

By the way, it is true that the toggle-type interaction used for the washbasin of the hotel we stayed in in Zhangjiajie, China was used for two modes of adding and draining water, but the situation where the button is pressed was not taken into account. The situation when pressing the button to drain the water is that you have to press the button by putting your hand in the already used water.

The interaction design element called toggle also has different uses depending on the situation. Again, a contextualized interaction design pattern language seems to be useful.
