    Nice video.
    I look forward to the integration of bimetallic and NiTinol materials for temperature and electric actuation.

    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?

    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 !

    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.

      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.

    • @AGI-Bingo
      @AGI-Bingo 2 місяці тому +1

      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.

      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.

    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 🙏

    • @SaurabhMhatre0
      @SaurabhMhatre0  2 місяці тому +2

      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.
