In this paper, we design application specific mechanisms and control systems to test and deduce the lifetime of custom-designed hinges and batteries. These hinges and batteries are critical components of prototypes for a patented smart toilet seat. The work done here was used to improve the existing design and to identify a replacement cycle for these seat components. The target audience for this smart seat is airports and venues with large crowds. The smart seat has a cleaning solution that is contained within the seat in a cartridge, which can be easily replaced by facilities. The seat includes a motion sensor, battery, and slow hinges inside of it. This seat employs a slow hinge which reduces the impact of repetitive opening and closing of the seat. The hinge lifetime was tested and to this end a specific mechanism was designed. In this test, time required for opening seat, closing seat, and total number of opening/closing cycles the seat underwent was recorded. Also, in another experiment, the lifetime of the battery powering the pumping mechanism was tested until failure, where the battery voltage fell below a specific value and could no longer pump the cleaning solution out of the ports. Finally, the results for each experiment were compared for different samples and analyzed. |
