In developing Setsuden-mushi, which operates without power during its standby, the most important thing I wanted the prototype making company to understand was how to procure the initial electric energy to power on a connected device such as a fax machine, and how to use it for power switching.

It's easy.

The line current normally used to ring the bell is used to start up the power-on circuit of the Setsuden-mushi. It takes much less than a second, and the power-on circuit of the Setsuden-mushi starts up with much less power than the amount of power consumption to keep ringing the bell over and over again. Of course, once the power-on circuit is up, it uses the electricity of the telephone line user (company). With this logic, we realized that we can turn on the fax machine and other connected devices with zero power consumption of Setsuden-mushi during their standby.

“We don't like amateurs, because we never know what they will think or say," must have been the thought of the employees of the prototype design company I asked to develop the second prototype of Setsuden-mushi.

Experts in their field try to find the best way to do things within the scope of their existing knowledge and solutions. This is not a bad thing, and it has been very helpful in improving products. However, it is often necessary to break out of the norm and break away from the norm in order to develop new products.
