Within lean, it stands for mechanical gadgets that improve your processes and conveyance systems, also known as karakuri kaizen. It originated with mechanical dolls in Japan, called karakuri ningyo. These dolls are first mentioned around 1500 years ago, but were most popular around 200 years ago.

Karakuri solutions have the advantage of moving load carriers automatically without having to use cost-intensive drive systems and additional sensors. The mechanical systems offer an intelligent solution for low-cost automation and are very low-maintenance, especially in direct comparison to technical systems.

What is Karakuri? The word Karakuri comes from Japan, combining the elements of “Kara” (mechanism) and “Kuri” (action). The essence of Karakuri lies in creating mechanisms that perform actions—no batteries, no wires, no software updates required. Think gears, pulleys, counterweights, and springs.

Karakuri puppets (からくり人形, karakuri ningyō) are traditional Japanese mechanized puppets or automata, made from the 17th century to the 19th century. The dolls' gestures provided a form of entertainment.

2017年10月10日 · Karakuri Kaizen is a mechanical device that generally improves work. The device uses only mechanical gadgetry, and shuns electric, hydraulic, or pneumatic power. It is also not controlled by a computer but rather by the design of the mechanics.

Karakuri uses mechanical advantage and kinetic energy to automate processes, significantly reducing the need for electrical energy and thereby crafting solutions that are not only cost-effective but also environmentally friendly. Efficiency: …

Karakuri means a Japanese traditional mechanical doll or miniature, or other mechanical device. In Chinese characters, karakuri is written as 絡繰, 機巧, or 機関, and in the old days, it was written as 唐繰.

2017年10月17日 · Karakuri is the art of creating machines without an external power source. After an introduction to the topic in my last post, I would like to show you some fundamental techniques for karakuri. I would like to pay particular attention to power management: Where do these machines get their power from, how do they store it, and where does it go?

2024年10月4日 · Karakuri kaizen is a lean manufacturing concept that comes from Japan, and its focus is on making simple, low-tech mechanical solutions to improve processes, without having to use electricity. Instead, these rely on basic physics principles, such as gravity, springs, gears, pulleys, and counterweights.

2010年3月16日 · Originally published in Japan, Karakuri is an introduction to the simple mechanisms, such as gears, cranks, cams, and levers, used to bring to life these amazing moving paper models or automata. Included are pull-out pages for you to use to construct your own moving models of the different types of gears.
