Lean and Industry 4.0

Industry 4.0 is one of the hot topics of modern manufacturing, although some (myself included) say that it is overrated. Lean is one of the older but also still important topics in manufacturing. In this post I would like to compare lean and Industry 4.0. What are the differences, what are the commonalities? Can they complement each other or do they conflict? Continue reading Lean and Industry 4.0

Karakuri Kaizen Examples

After an introduction and description of the fundamentals of karakuri kaizen,  here are some different karakuri kaizen examples for a wide variety of uses. Most of them are from the 480 exhibits at the the Karakuri Kaizen Exhibition 2017 in Nagoya, Japan; others are from the 2017 OPEXCON in Stuttgart, Germany. Here is my attempt of a structured overview, even though some of the points below may be overlapping. Continue reading Karakuri Kaizen Examples

Fundamentals of Karakuri Kaizen

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? I will also (very !) briefly talk about kinematics, and even some karakuri ideas that go beyond kinematics. My next post will have lots of examples, mostly from the Karakuri Kaizen Exhibition 2017 in Nagoya.

Introduction to Karakuri Kaizen

Karakuri NingyoRecently I visited the Karakuri Kaizen Exhibition 2017 in Nagoya. This was a very impressive exhibit, and I learned a lot about karakuri from the many different examples shown there by over one hundred exhibitors. Organized annually by the Japan Institute of Plant Maintenance, it is to my knowledge the biggest showcase of karakuri in the world. This was an exciting visit that I will process in a whole series of blog posts on karakuri (Fundamentals and Examples)

Karakuri is the use of mechanic gadgetry rather than electric, pneumatic, or hydraulic devices. Definitely no computers! Within lean, it stands for mechanical gadgets that improve your system. Time to look closer at what I learned from this karakuri exhibition. Continue reading Introduction to Karakuri Kaizen

Industry 4.0 – What Works, What Doesn’t

Industry 4.0 is (still) all the rage in manufacturing industry. I’ve already took A Critical Look at Industry 4.0. A lot of Industry 4.0 is hot air with a return on investment only far into the future. However, there are a few ideas that actually may work soon enough. In this post I would like to give my views of what works in Industry 4.0 and what doesn’t. Continue reading Industry 4.0 – What Works, What Doesn’t

Visit to Euromold for the Latest in 3D Printing

3D printed tower with internal staircaseThe next Euromold trade show in Frankfurt will be in a few weeks. While the show generally presents products related to moldmaking  and tooling, they also have a large section on 3D printing. This is a good time for me to talk about 3D printing and my last visit to Euromold last year. Continue reading Visit to Euromold for the Latest in 3D Printing
