A Mechanism for Toilet Seat Sanitation

Students of Indian Institute of Technology, Madras Arvind Pujari and his team members Shashwat Jain, D V S S S Kushal Kumar Reddy, Subham Kumar Sahana and Tanay Garg won the GYTI award appreciation for developing a A Mechanism for Toilet Seat Sanitation.

A simple, purely mechanical device is developed to ensure the sanitation and cleaning of the toilet seat by the push of a foot pedal which can be implemented as an add-on to the existing toilet structure. The mechanism consists of three parts. a) A Lifting Mechanism: A foot pedal lifts the seat, as seen in dustbin lids. b) A Spraying Mechanism: When the seat reaches its apex position, a nozzle is automatically pressed, spraying a sanitizing liquid onto the seat. There are four such nozzles, thus ensuring that the entire seat is sterilized. c) A Wiping Mechanism: The wiper is a rod attached with a removable sponge, located at the back end of the seat, so that it does not encumber the user. When the foot pedal is pressed, the seat is lifted and the wiper is lifted along with the seat until it reaches the front edge, thus cleaning the seat of any dirt or water left by the previous user. Then the spray heads attached to the lid of the seats are pressed and spray a sanitizing liquid on the seat. The spray is uniformly spread and wiped across the seat, by the wiper, thus completely sterilizing it. There are many advantages of this mechanism over currently implemented methods (such as disposable seat covers, sanitary wipes, sanitary sprays and UV light). Thus, this device provides a low cost (the device will cost less that 1000 to manufacture and set up), user friendly, touch free and electricity free method of sanitizing and cleaning the toilet seat by the simple push of a foot pedal.
