Nowadays, public toilets use sensor auto-flush systems instead of manual flush systems, because using manual flush systems may be unhygienic (everyone touching the flush button/lever, contact with germs), and also due to the fact that some people may accidentally forget to (or purposely choose not to) flush the toilet after use. The implementation of sensor auto-flush systems solve these problems.

However, using the sensor auto-flush systems has its own set of problems as well. Due to the system being damaged, or not being able to detect the presence of users properly sometimes, this could lead to the toilet flushing when still being used. This could lead to wastage of water (continuous unnecessary flushing) and a possible unhygienic inconvenience (imagine the toilet water mixed with the end results of your last meal, splashing up against your rear end while you are peacefully doing your business ><)

Possible solution: a micro-switch/motion sensor pad within the toilet seat that activates the flushing, only after the user has sat down and stood up from the seat?
