In order to improve the efficiency of the dispenser several design changes were implemented. One of the design change is the pumping mechanism in order to reduce friction and reduce wear on the tubing. In the newer design instead of having the gears squeez the tubes to pump the fluid, the gears will be used to pump fluid directly into a tube going into the valve. Another design change is implementing a battery compartment which is more water resistant. Since in the previous design some water used to leak into the compartment. A new valve mechanism is implemented to prevent fluid leakage after dispensing. Lastly, the motion sensor was changed to infrared light sensor for better sensitivity and controlled flow.
