Clean Hands / Public hand washing devic

Clean Hands
Clean Hands

The idea is to achieve a truly efficient way of hand washing in the context of local water shortage and poverty. The traditional way of hand washing requires users to have standardized hand washing behavior, which is spontaneous and not easy to supervise, and it is difficult to form habitual behavior in the user behavior model. At the same time, a lot of water is wasted every time washing hands. Therefore, the design not only uses the local low-cost materials, but also integrates the traditional Chinese mortise and tenon structure to realize the real low-cost and efficient hand washing behavior.
