Caring 38-year-old Chinese inventor Chen Gongke has created a hands-free automatic hair-washing and drying machine for people who cannot manage to wash and dry their hair themselves. He came up with the idea after seeing his paralyzed late grandmother struggling with day-to-day personal care. It has taken Chen nearly 16 years of trying to come up with the perfect design (which he has now patented). At present, the machine comprises of a control panel, two water tanks and a motorcycle helmet. Over time Chen hopes to create a machine which can be bought in stores. Take a look!
