Sonar toilet clog analysis

To determine the exact nature of the clog, to allow more optimal unclogging, I propose to use sonar.

This could be integrated into the toilet, or an add-on device (or even a portable device, which would be more cost-effective for janitors).

It uses either transducers coupled to the porcelain of the toilet to transmit sonar pulses into the toilet and detect the reflections, similar to how frustrated total internal reflection touchscreens work with light, or a transducer that you stick into the water/soggy toilet paper. The return signals are processed using DSP, and the shape of the clog is displayed on a screen.

This provides feedback to the unclogger, so it/they can optimize the unclogging technique for the characteristics of the individual clog.
