You'll have to speed it up, it's too slow for me to pay attention....and needs more volume

Uh-huh. Your "details" didn't seem to show much detail, anyway. On top of that, Sumitomo SM-Cyclo may already have discovered this.

That had audio? I did not hear anything at all. Not only that, there are more than one moving parts. I suspect the ceramic balls will wear out before this gets anywhere. The only part where it appeared to be doing anything was when the thing was moving a dial indicator. so the spinning ball is tied to a lead screw that moves the dial indicator?

It is not clear at all how this thing is supposed to work.

Well here's some feedback. I have both the Youtube and my computer volume all the way up and I can barely hear your video unless everything is absolutely quiet around me.

Any video presentation I can not hear or that is so loud its distorted with the volumes turned way down gets ignored.

I'd suggest you manufacture your own machines that incorporate your device. I just think its too specialized to create a bidding war and make you rich.

I'd find something other than a ball screw to compare it against. There is no practical, functional resemblance between the two.

It may have applications in precision adjustment of objects (Mirrors, surface plates, micrometer tables) but a ball screw it ain't. Lifting heavy objects .1 mm has already been done.

The problem with some patents is that they are more of a solution looking for a problem than a solution to an existing problem.

Also, remember that a patent does not assure a market for your invention.

Good luck.

What mechanism would you suggest comparing it to, if any?

TIA

What was your vision when you invented it?

I have "invented" many things over the years. I never created anything that was not intended to serve a useful purpose. I guess that means I am not an artist.

I've built things from metal coat hangers that served a functional/practical purpose. I did not attempt to patent them, but they worked.

Same with a patented item. I already knew what it needed to do and knew that no one else had ever done what I was attempting to do.

Are you making another ball screw?

If you truly invent something new, there should be nothing to which you can directly compare it.

A Trammel of Archimedes is also informally known as a bulls*** grinder. This might or might not be a useful parallel.

What is the invention worth when the description is already in wikipedia?

It is worth a patent.

Depending on the failure to perform competent patent searches.

And, the ability to perform competent patent searches. The result may well be the same.

Surely you know that patents do not assure a workable invention/device.

Just look up a few 1800s patents, and see the jokes. Today isn't necessarily much better.

So now we know what Mona Lisa was smiling about....

The concept is interesting and whilst a reduction gear is shown on Wikipedia, the use of a cam to drive linear motion I think is your patent claim. I would heed the comments made about the video and reduce the length to under a minute.

Converting rotary motion to small linear movement is better achieved by driving a threaded shaft (A) in a nut and having a smaller threaded shaft (B) inside (A). (B) having a slightly different pitch will move (B) the pitch difference per revolution. The bearing area is much larger than your concept.

This is much cheaper to manufacture and has been around for years.

This concept can be spread over a large area by using several identical units driven by a tooth belt.

Please forgive my flippant reply, but at first sight just reading your OP, I immediately thought it sounds like me on my bike.

Lots and lots of high speed rotary motion and very little linear motion.

But from the link your cycloid drive it looks impressive. Well done! Albeit, it was slow work watching it. Your on-line demo needs speeding up. Engineers contributing to CRA will see instantly what you are getting at.

But I have an uneasy feeling that you will have trouble getting a patent, and if you do get one, it will be difficult (costly) to enforce.
