On the Safety of Workers During Corona – Part 2

The Corona pandemic is still spreading around the world. Some countries could contain the virus, while it still spreads in others. Other countries are experiencing a “second wave”, which is bigger than the first wave. One of the potential ways to get infected is at work. Hence, I would like to write about ways to reduce the risk of infection at work. This is the second post on workplace safety during Corona. After this, another post will look at how Corona influenced logistics around the world. As before, I am an engineer and not a virologist. Hence, all virus-related information is only to the best of my knowledge. Use this information at your own risk. I still hope that it helps you to provide a safe environment for your people!

On the Safety of Workers During Corona – Part 1

The world is suffering from a pandemic. SARS-CoV-2, better known as the coronavirus, is killing people all over the world and damaging the economy. One major topic (among many) is how to keep workers safe during the pandemic. Hence, I would like to provide my thoughts on this topic.

Please note, this is not a guideline to solve all your virus-related manufacturing problems. The current situation is causing headaches for most manufacturing companies, and these headaches are hard to avoid. Second, I am an engineer and not a virologist. Hence, all virus-related information is only to the best of my knowledge. But, come to think of it, so is my engineering knowledge too. Use this information at your own risk. The recommendations here are based on the common recommendations to avoid infection, with a view on how they can be applied on the shop floor. This is the first out of two posts on worker safety during the pandemic, followed by a post of the influence of corona on logistics.

Design for X

In my last couple of posts I looked at design for manufacturing and assembly DFMA. However, there is more out there. Often, they are grouped as Design for X, where X could be anything related to the product life cycle, including development, production, shipping, servicing, use, disposal, and many more. There seems to be a large number of more-or-less well-known terms that are used somewhere. Many of them claim to be essential, but not all are. If you try to do them all, you will never get the design done. Focus on the ones that are most promising for your case. After all, all designs are designed for something, usually a trade-off of functionality versus cost. This is sometimes also known as design to cost.

Design for Assembly Questions – Part 2

Design for assembly (DFA) is a large part of design for assembly and manufacturing (DFMA). In my last post I looked at how to improve fastener design and usage as well as reduce the part count. In this post I will look at reducing the number of variants, secondary processes, and making handling easier. This post continues my previous post with questions that can be asked in design for assembly.

Design for Assembly Questions – Part 1

Assembly LineIn my last posts I discussed basics and workshop preparation for design for manufacturing and assembly (DFMA), as well as the questions for design for manufacturing (DFM). The juiciest part, however, is the options for design for assembly (DFA). This post starts with the specific questions to ask for design for assembly. However, there are so many options that I won’t be able to fit them into one blog post, and this will continue in subsequent posts. Anyway, let me show you how to do design for assembly.

Design for Manufacturing Questions

After two post on the basics and workshop structure, I can finally start to go into the details of which questions to ask for design for manufacturing (DFM). In subsequent posts I will have more questions on design for assembly (DFA), which can of course be combined into design for manufacturing and assembly (DFMA).  I will also have a brief refresher on creativity techniques. Let’s start asking questions!

Design for Manufacturing and Assembly Workshop Preparation

Design for manufacturing (DFM) and design for assembly (DFA) or its combination, design for manufacturing and assembly (DFMA), as well as its many design for X variants are a way to improve a design beyond its mere functionality. In my last post I gave you a basic introduction. This post will look at the prerequisites for organizing a design for X workshop. Subsequent posts will look at the different questions you can ask to further design for manufacturing and assembly.
