SS19 – Smart Toilet

According to the information from the Food and Environmental Hygiene Department in 2019, there were over 8,400 complaints about public toilets in the past three years. The problem of public toilets usually comes from hygiene and smell. To solve these problems, we have designed and made a smart toilet system with 4 major functions: (1) We use A.l. to identify the shapes of poop and give advice to your health status based on the medical Bristol Classification of the Stool. As there is no relevant poop database available in the world, we made the poop samples by clay and paint. (2) We use the method of illuminating UV light to the toilet seat at a close distance. It kills the bacteria on the toilet seat and quickly clean it. (3) We use pedals with adjustable height with people of different heights. Kneeling at a large angle (such as 35 degrees) is a more comfortable gesture to excrete all poop quickly and easily. (4) We use an air pump which is under the toilet seat to take away the bad smell directly. No one knows you are pooping and the next toilet user feels good!
