Even if patented, thanks for sharing your work. The inspiration for other engineering students is invaluable, I can already start to explore flexures like this but using centrifugal phenomena and or thermal expansion as actuation mechanisms for more autonomous operation or different environmental conditions, and cite your work as a source of inspiration/data.
Every time someone says "our patented", I hear "please appreciate our ability to sue you should you want to use this". So, is this a step to prevent patent trolls from causing damage, or a means to make money?
@@SaurabhMhatre0pretty sure this has been done in many variations. you might want to double check your prior art due diligence so you dont get counter sued for infringement and failure to achieve Freedom To Operate.
WOW, this is amazing. I love it. It reminds me of AI. It's full of potential for anyone to use, cheap, and waiting for millions of problems waiting to be solved by anyone. ❤
Impregnated and/or sputtered with copper and this could be used to focus the magnetic field of a toroidal coil in situ. 🤔 Very cool compliant design! 👍
Pushing op idea to the limit.. can you make a motor or generator or transformer out of this? I imagine many more thin strands, and maybe a few of these stacked or weaved together. Wonder what electronic applications this could unlock, especially if miniaturized to MEMS levels...
@@AGI-Bingo I like where you're going with this! ✌️ It would allow for quick tuning of coil geometry and layout, and stacking multiples in a parallel or series based on your needs.
@@orpheuscreativeco9236 yea i was gonna mention tuning the geometry to effect the electromagnetic properties, but not sure what the effects would be, so waited for someone else to bring it up haha I also proposed some ideas in other comments, hope to get a reply from them, For example making it oval, to make a pop-up instant tent, and adding lockable creases so it can be folded when flat for extra compactness
@@orpheuscreativeco9236 I have recently seen companies like PCBway putting tiny magnetic array generators on tiny boards. Is this the kind of application you are talking about?
Very interesting ideas guys, I'll love to use these kind of structures as EM brakes. A copper flexure could deploy due to the centrifugal force of high RPMs changing its orientation with respect of a permanent magnet's B. Or a vent actuated by the thermal buckling of the material.
Если каждую половинку можно сделать из множества сборных сегментов, то возможно изготовление каркаса для быстровозводимых сооружений и зданий, типа вигвам, палатка, юрта, чум. Возведение каркаса одним движением. При чрезвычайных ситуациях очень полезно иметь такие сооружения и для активного отдыха тоже подойдёт.👍
That's correct ! For large scale structures fabricating it out of a single sheet is limiting hence it can be looked at as a kit of parts. I surely plan to look at the emergency shelter application - have been very inspired by Buckminster Fullers 'dome being transported by a helicopter' image !
Cool to see this idea being played with at larger scales, but this certainly isn't new. I remember seeing these kind of flextures in paper craft books and Australian Geographic stores in toys 15-20 years ago.
It is surprising that some of the content of this video was included under the name of several normally well regarded institutions, - several claimed possible mechanisms involving interpenetrating surfaces somehow folding flat 'thorough' each other and illustrated by computer generated renders - make the whole thing reminiscent of an hastily contrived end report of an uncompleted undergraduate assignment.
How can it work as a turbine if the twinned blade surfaces are twisted in opposite chiral directions? Love that you used grasshopper in rhino. My favourite
Great point. I surely havent gone in depth at all but it will need some development . I agree right now in the render the two sets of opposite fins are similar but for that application one set could be biased to have more surface area , lightness etc as compared to the other. The other could just be frames without a surface so as to offer no resistance to the wind. Rhino + Grasshopper made my life so much easier !!!!
The turbines are so awesome!! And also the half wall at 3:50 didnt see the flat version of it, can you please show it. Also do you think you could make a shape like an igloo? Where theres ceiling structure above, but a door or even a wide open arc like a cave , similar to the half curved wall, but bigger and with overhead ❤
The half wall for now is just a render but it can be made using different diameter fins connected together. Think of a polar array of fins where all the fins are not same but have different (global) diameters
This is so awesome ❤ I'm guessing you could make this out of a material that can be cured.. for example the table example, make it with a uv resin, and make it hardened, remove tabs, give it glass like qualities, incredible
Oh wait... It's complient.. meaning already Ridgid and under tension/compression haha my bad. But the idea still stands.. somehow (maybe with heat) relax the tension, without deforming somehow, and reform it solid. I think I'm just interested in making the final object super solid, even if it's a one-way process. 3:07 I noticed you put some weight on the table with your hands and it easily deformed.. So I wonder how you can start with the complient mech, but end up with a glass-like hard object which will not deform. I think uv resin might be awesome for this , Thanks and All the best!
Exactly , I am pursuing that direction too :). And that's correct - the table in the video isn't as stable as it should be . For now it was just a scaled up version of the small mechanism. I have made some changes in the smaller models which increase the stability quite a bit which I soon plan to implement in Table 2.0.
Flexures are cool, but IRL, every part that I encountered that used flexing as a mechanism, eventually failed due to fatigue. It's Usually the first thing to go.
Those designs were not optimized for lifetime. If you do not exceed conservative elastic limits then some materials will last almost for ever. A snap action 'Microswitch' can be made with incredibly long mechanical lifetimes. Many other examples of long life flextures like truck leaf springs. Even a metal retractable tape measure has very long life absent abuse.
Haha.. I know exactly what you mean . This was vet inspired by Origami, Kirigami and Active- Bending principles. I didnt have a pop-up book when I was a kid but do have a bunch of them now :) . 'Elements of Pop-Up' is my favorite one !
Very interesting. A use perhaps in kinetic art forms which is an interest of mine at the moment. As for patenting,,, good luck with that as it is in essence “origami”.
The vast majority of use case examples almost completely failed at the function that was being demonstrated. (ie a lamp shade that doesn't shade the lamp)
You are correct . Its not a finished ready to use product yet . I covered a 'breadth' of speculative applications it can be used for and I am currently going in depth to see which of these make more sense than the others and what kind of changes / developments are needed for the same.

What’re the chances of accessing an STL or model file? (Assuming 3D printing is a viable means given its not isotropic) I wanna build one to better understand the mechanism
If super big, this would make a greate dome! ❤ Also! Do you think you could make an oval shape??? This looks like it could be an Incredible Tent! Especially if it can folded when flat 🤯 Trying to imagine a print in-place flat lockable joints so that it can be folded x4, opened, and locked. I imagine a coin with a crease in the middle.. turning 90° to enable/disable foldind of the joint. =⦶= open, can fold =⦵= closed, cannot fold Like a map, open all the folds, lock all the joints, twist... Bam! A tent The joints need to be really good, flat, and durable, and with a color indication of opened joints to help close all quickly. Would love to know what you think, and especially if you think this can be oval 🙏 Awesome work!
Yes it can be oval shape. Based on the length (spiral) of the individual beams. And the coin -crease example is right on point - to make that a possibility. For the major part of the project I was always seeing that 'being able to cut this out of a flat sheet is an advantage' but I also know for certain (larger) scales other fabrication methods can be used. I have a prototype which I 3d printed which is a working mechanism right off the print bed. The 3d printing also allows for programmability of the 'cross-sections' of the beams which opens up a lot of opportunity.
I am yeat to compile some for 3d print . But here is a link to someone who had made a version some time back . - cults3d.com/en/3d-model/art/3d-flexible-kiriform-re3d
Wait if you can make turbines, you can make drone rotors... So the driving car example, could also be a flying drone.. can you tell your software to optimize for Lift ? Haha😅
The domain chart in 4:00 is really cool ❤ I can see you already you thought of most, would love to see a car/drone hybrid! And also investment into architecture especially Shelters and Tents. If you can get the coin creases down good and fold a big tent into a bag like a folded map, that would be something great to invest in ✨

I can imagine a sci-fi scene with someone from space throwing this down at it turning into a micro fusion glowing generator haha
would be a cool VFX animation
For the longest time I used to use the 'Jetsons' car as an analogy :p
The adult in me thinks this is an outstanding achievement. The child in me is just reminded of Homestuck.
It is also act as an emergency shock absorber that stays flat and deploys when needed

Given the right geometry and materials this could make a great universal soft griping tool for light duty on a robotic manipulator! Hmmm possibilities
Look up Nitinol stone extractors. I think combining the technologies might be even better.

If it was ultralight, it could make an interesting kite.
A 2-string kite that allowed deformation on demand could be cool.
It's a tent too
Nice 👌
Add a small hidden spring to the two layered one could make a cool ball 🏀 or game for kids
