Problems solved by technology

Based on the above, a very simple physical simulation experiment device for a sink was designed in the early stage. It is composed of a PVC test frame for placing electrodes and a wooden board with guide grooves. The PVC test frame is pulled by hand, and the accuracy and reliability of the measurement are very poor.
