I work in an R&D lab of a Swiss watchmaking company, and I can tell you that compliant mechanisms are currently by far the hottest topic in research for mechanical watches.

This spring has been recently replaced by Zentih using the compliant mechanism etched on a silicon wafer, in their new watch called the Zenith Defy Lab. This breakthrough could actually mean mechanical watches could become more accurate than their quartz counterparts once again, all thanks to the compliant mechanisms

This is amazing. As a mechanical engineering student, we are learning all the ways to prevent bending and shear, whilst you guys are taking advantage of it to make advanced mechanisms.

That's because the headline is not even true. If you are trying to design a CNC router, then bending is to be avoided at almost all cost, otherwise your machine will only do three things: 1) destroy your workpiece, 2) destroy your tools and 3) destroy itself. If you don't understand why, then you still have a lot to learn, "mechanical engineering student". Engineers who are designing bridges and railways and pipelines, however, have learned centuries ago that compliance against thermal stress, etc. is absolutely required to prevent failure. You just don't know what you don't know.

@@farrel_ra Most machine tools are made for highly rigid tooling processes. If the tool is allowed to move in the direction in which it "bites", then we get a destructive positive mechanical feedback where the machine gets deflected ever farther into the wrong direction. The way to counteract that is with rigidity and mass. "Soft" machining can be done, of course and it's highly useful. That's how optical manufacturing processes work, for instance. Grinding and polishing can produce near atomic precision with machines that are all but precise and are completely floppy at the scale of the final precision. I find that absolutely fascinating in its own right. A stone mason is, if you want, also a "soft manufacturing process". He constantly compares the shape of the stone he has with the shape he wants. The tradeoff is time... soft processes take much longer than a rigid process. So yeah, there are plenty of applications, but one has to chose wisely.

@@lepidoptera9337 I do not have any type of engineering education, but from what I remember in high school physics, is the use of compound material in things like bows for their compactness and good force multiplying. It depends on the use case. I remember we had tent-like structures on our school fields for shade. One was made by hollow steel pipes, one was made by the bamboo and ropes (very common in my country), when a sudden stronm hit. The steel pipe tent did not suffer damage, but was blown away and the joints suffered damage. The bamboo tent swayed a lit bit, but did not collapse. The bamboo itself suffered no noticeable damage. My teacher had a thing about teaching us things after whatever failed after torrential storms (common in my area) and, he loved to point out all the coconut trees still standings, compared to some of the some thick sturdy trees uprooted or damaged.

Amazing video! I love the innovations insanely smart people come up with!!

Im simply baffled - it is elegant, simple and beautiful in function and design and with extreme performance.

I used a chainsaw quite a bit and let me tell you I would've been saved a few headaches if the clutch had been a single compliant mechanism instead of the mess of metal and springs that it is. That is an amazing practical application for this.

I agree with similar comments that this topic intrigued me like no other. It is almost like modeling an exoskeleton but in a future modernistic manner. This seems like future tech that is so cool that it has come back in time for us mere mortals to marvel over.

This is incredibly cool, and ALSO what a nice and charming guy Professor Howell is!

The clutch is actually a centrifugal clutch, exactly like the ones in the chainsaw, but the one in chainsaw have 2 or 3 springs, and those springs break all the time. So these parts would be much more efficient since they’re made out of one piece. Nice!

@davidgutierrez8297

Those springs means it is easy and cheap to replace. If it's all one piece, you will have to throw it all away for a single failure. Anybody who has used bending plastic hinges knows that absolutely suck. Ask any guy who regularly uses toolboxes. The good stuff has metal hinges.

I love the way they were peeking in the room.

Love seeing advancements in technology and the human mind evolving

Practical examples of use of compliant mechanisms in everyday products 1. Every shampoo bottle uses a live hinge made by injection molding - very cheap, durable and assembly free. 2. Computer mouse buttons use flexures (those bendy things you see throughout the video). The microswitch inside it has a diaphragm flexure and the top casing flexes when you press on it to transmit the compressive force. Older mouse models had separate distinguishable buttons, now its all one piece. 3. Cable ties have a very small tooth with a flexure that engages a rack. You can often reuse cable ties by disengaging the tooth from the rack using a pin and pull out the rack while holding tooth off the rack with the pin. 4. All plastic components of every product you use has a snap fit for assembly - no requirement of fasteners. 5. Every book uses live hinges (crease where you bend) for opening and closing. 6. Some cheap click type ball point pen (e.g. Bic retractable pen) uses flexures to keep the extended pen nib in its position. 7. Tic tac box uses living hinge for the lid. 8. Volume rockers on your cell phone uses flexures instead of springs to bounce back 9. If you have a wind up pendulum clock, the pendulum is suspended by a flexure for avoiding friction caused by use of a pivot. 10. Snap fit locks for straps in duffle bags/backpacks etc. 11. Some shot microphone mounts uses flexures for vibration isolation. 12. Camera lens covers uses flexures for springs for holding the cover on the lens. 13. Disposable food containers, clamps for IV lines. 14. Paper clips. 15. Foldable plastic forks found in ready to eat noodles have a living hinge in the middle for folding. 16. Leaf springs in vehicle suspension (Thanks to Heartycoffee in the comments for suggestion). 17. Tweezers and forceps (Thanks to randal gibbons in the comments for suggestion) 18. Safety pins (Thanks to DrBrainSol in the comments for suggestion) 19. Accordion-style toilet plunger (Thanks to Gary Young in the comments for suggestion) p.s. I will add more to the list later. I love flexures and thank Derek for making a video on compliant mechanisms with Dr.Howell

@@PebblesChan Yes certain consumer products do have badly designed living hinges and I have had similar experience. However, a properly designed living hinge should last thousands of cycles if not more. They would fail prematurely if they are not designed properly, use of wrong type of plastic, if they are bent over their design limit/excessive force, if they are subject to extreme heat, or if they are subject to UV light(sunlight). Please do not get me wrong. I use them all the time. If you design, use them properly they are shown to last at least a million cycle as the Professor in the video claims. Even a 3D printed flexure lasts hundreds of cycles for me when I use them in my lab for my experimental setups. Often times they simplify design with no assembly required. They are indispensable in applications where you cannot use lubricants. for e.g. MEMS, certain medical devices.

Many are not properly designed and having machines cyclically repeating the same action does not emulate real life where there are substantial differences, variances and exposure to idiots. (No one can engineer against stupidity). I have a car window switch that comprises of the simplest possible machine essentially being just a rod of flexible plastic that pushes onto a copper leaf switch. Just with normal use the end shortens being unable to make the copper leaves to make contact. The biggest problem is that the replacement price of that switch is about $250. In the same vehicle there is a plastic combination stalk mechanism (its second) that now fails to invoke the fast wiper speed unless one deliberately over twists the switch and holds it there. The price for that is about $600. The original plastic combination stalk mechanism failed by not being able to invoke high beam. It's amazing that something that costs cents to make can cost so much as replacement parts. What I find most amazing is how pressed metal sheeting can outperform solid cast metal structural components.

Oh no.....it is blown.....tons of tiny intellectual bits are now floating around incoherently bumping around my room never to return to their natural state.

In the military we use a lot of carbiners [sic] and S clips and about 2007 they changed from using springs to bendy part to be a piece of steel with offset connection to the solid bit.

this pair of toungs is so cool, in its most compressed state it has a theoretical infinite force ratio, so it increases preassure and decreases motion the more compressed it is

This video was hella satisfying

Centrifugal Clutch on my old go cart (driven wheel) had a cylindrical aluminum housing. Driving through the woods one day, caught a branch in the chain sprocket. I surmised turning the wheel in reverse could free it, but more leverage if I could spin the clutch body & sprocket to release the branch. My bare thumb & fore-finger slid off the clutch housing with a sizzle, so fast that it didn’t hurt, but the white char endured for a while (no scar remained), but lesson learned.

Flexible machines and soft robotics also may have huge implication in the field of prosthetic limb and humanoid robots. Nature uses soft materials predominantly and stiff ones sparingly. So it would not only be more realistic, but from all these advantages shown in the video, can lead to effective solutions to problems. For example, letting a prosthetic hand have a firm grip on some irregular objects.

In 1968 I did research to try to put a machine, a molecular beam, on a glass slide, that could then be rotated to get three way velocity specification. The microchip etching needed had not yet been invented (I tried to use asphalt and HF). But there were mechanical components too. These kind of etchable devices could serve for controls. So far as I know, the device has never been made or researched. Maybe it's time to try again using these advanced mechanisms.
