Welcome to the PF. :smile:In summary, this individual has been working on a way to create an actuator that emulates muscles, and has been getting sidetracked by other ideas. They hope that their article will be interesting to readers.

TL;DR Summary
Hi all.

To begin, we all know that in a typical cylinder for example, the pressurized area inside the barrel far exceeds the axial. Actually, once the stroke of a cylinder exceeds 1/4 the diameter, the radial (wasted) forces equal the linear ('used') forces generated.
Subsequently, I had the idea to keep cylinder ends stationary, and to find some ways to expand the cylinder wall so to speak.

I have done some preliminary work in this area, and in looking at what happens to the volume of fluid itself reveals quite a few incredible things, and opens up a very large rabbit hole in actuator design, pump design, even to propulsion & combustion chambers & the like.

Anyway, I began an article for a cylinder that emulates a muscle (as I see them functioning anyway), but this change in paradigm sent me on too many tangents.

Subsequently, please bear in mind the article is unfinished (is Pt 1), and is an incomplete rough draft. It's also just in wordpad, a simple program on a simple computer. please forgive any errors in presentation.

I hope you find the concepts as interesting as I did. This article is free issue.

be well all, happy designing :)

lol, it ends up a simple 'wordpad' file isn't supported. If you would like a copy of a preliminary article, please message me or tell me how to get around this haha

Welcome to the PF. :smile:

For right now, your thread is in the Moderation Que awaiting approval. We need to see the file before we can decide if this is a valid thread start or not (we don't allow personal theory development here, but if it's just a question about the efficiency of a different sort of mechanism, we may be able to allow it).

Please use a free PDF writer (like PrimoPDF) to print your WordPad file as a PDF and attach it to a reply here. I'll have a look to see what we can do.

Thanks.

Just one preliminary comment: "Wasted forces" isn't a thing. A force against an object that doesn't move just does nothing in a hydraulic system. It doesn't matter.
 

1. What is the hydraulic/pneumatic paradigm shift?

The hydraulic/pneumatic paradigm shift refers to the transition from using traditional hydraulic systems to more advanced pneumatic systems in various industries such as manufacturing, construction, and transportation. This shift is driven by the need for more efficient, lightweight, and eco-friendly technologies.

2. What are the main differences between hydraulic and pneumatic systems?

Hydraulic systems use fluids, typically oil, to transmit power and control machinery. Pneumatic systems, on the other hand, use compressed air to achieve the same functions. Pneumatic systems are generally more lightweight, require less maintenance, and have faster response times compared to hydraulic systems.

3. What are the benefits of the hydraulic/pneumatic paradigm shift?

The shift from hydraulic to pneumatic systems offers several benefits, including increased efficiency, reduced maintenance costs, improved precision and control, and reduced environmental impact. Pneumatic systems also have a higher power-to-weight ratio, making them ideal for applications that require quick movements or high forces.

4. What industries are most affected by the hydraulic/pneumatic paradigm shift?

The hydraulic/pneumatic paradigm shift is primarily affecting industries that rely heavily on heavy machinery and equipment, such as construction, manufacturing, agriculture, and transportation. However, the shift towards pneumatic systems is also being seen in other industries, such as healthcare, where precision and control are crucial.

5. What challenges are associated with the hydraulic/pneumatic paradigm shift?

One of the main challenges of the hydraulic/pneumatic paradigm shift is the initial cost of transitioning from traditional hydraulic systems to pneumatic systems. This can be a significant investment for some industries. Additionally, some industries may face challenges in finding skilled workers who are knowledgeable about pneumatic systems. However, the long-term benefits of the shift make it a worthwhile investment for many industries.
