The TV programs I often watch include “0655” and “2355”. The content varies from day to day, but “Pokayoke” is sometimes introduced. “Pokayoke” is a mechanism or device installed in a production line, for example, in a factory to prevent work mistakes (from Wikipedia). “Pokayoke”, a solution to make people notice their mistakes and thus to prevent “Poka”, accidental, small mistakes, may be famous as one of the basic concepts of Toyota Production System. It seems to be sometimes called “Poka-Yoke” even outside Japan.
In the program, one “Pokayoke” was introduced. When cleaning the inside of a large tank, you will go inside with a deck brush, you can prevent forgetting to take out the deck brush by connecting a string to the deck brush and keeping the string out of the tank. With such a little ingenuity, you can prevent big mistakes.
If you search for “Pokayoke” on J-PlatPat, 34 patents and utility models and 10 trademarks will be found. Mistakes are common in any job, not just in the factory production line. I also want to do my daily work while devising with “Pokayoke”. (Syszo)
