Karakuri in Japanese, means moving something by an elaborate mechanism consisting of strings and coil springs like in a clock.
It has a long history in Japan; it is said that karakuri is described in a literature dating back approximately 1200 years.
Karakuri is characterized by the absence of a continuous power source. Like in a watch, you may compress a coil spring and then the mechanism works for a long time. A load is placed in the mechanism and it compress a spring and the mechanism starts working.
In the recent monodzukuri field (manufacturing), people’s eyes are on karakuri kaizen based on the traditional karakuri mechanisms, which elaborately incorporate movements by gravity or leverage, for instance. Karakuri mechanisms are simple and cost-effective. The simple mechanisms solve many problems in the workplace, in terms of quality, operability, and preventing failures.
