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.
@@iPlayDotaReligiously 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.

Larry was my Masters Thesis advisor--he is one of the great people I have known in my life. Compliant mechanisms are very cool. Thank you for posting this video-love your channel. For any who have not seen it, you should check out the Nova episode "The Origami Revolution"--which covers more BYU Compliant Mechanisms research--with origami.
@Nathan Masters , very curious, do you guys take inspiration from biological mechanisms (i.e biomimicry)? Seems like there would be plenty of those in nature.
I saw "the most cited book on compliant mechanisms" and thought... hmmm, this seems familiar, where have i heard this exact phrase before. Now i remember it was from building mini-nerf guns
Dr. Howell is an amazing Professor and a great guy. I was lucky enough to take his compliant mechanisms class. I'd highly recommend reading his book and learning about how to design compliant mechanisms using pseudo-rigid-body models. That's when your mind will really be blown! To think that we can take complex mechanical systems and make them compliant using a simple formula is what is really quite amazing. Great video!
Complaint mechanisms sounds more like a government employee training program (yes I know it was a typo, but this is the internet, one does not simply walk by an interesting typo).
@Ryan I spent years in schooling and most of that time, I was self taught and extremely inventive getting around the stupidity of so-called teachers. However, a rare handful in my 28 yrs of formal education I met educators such as this man. They were inspiring and could clearly explain their subject(s). I am truly happy for you that you too have had the pleasure of experiencing learning from someone who enjoys investigating, discovering, inventing, creating and learning and then sharing all of this with others.

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.
@@veritasium I found the clutch to be intresting version of something that I've already seen before: The clutch in a top fuel dragster. The switches were very cool, that they can be made at such microscopic scales!
Not saying that this isn't cool as hell, but does it really bring that much innovation to the centrifugal clutch that scooters and chainsaws already use? It seems it would be lighter for sure and maybe have cheaper (?) manufacturing costs, but other than that I don't think it would benefit them that much. Still a good take on an established technology.
Lighter weight, better reliability, reduced wear, longer component life and cheaper to boot, Rotax have been using them in their Go Kart engine for a while now, made the old style clutch completely obsolete.
man i really pity people who find this channel boring or uninteresting, i find insulting those who find it a disservice like i have seen lately. 10M views AND 11M subscribers... undeniable legend
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
Haha I was thinking to myself "if compliant designs are so good, why aren't they used everywhere?". Turns out they *are* used everywhere and I'm just unobservant :)
@@skulleeman Yes They are omnipresent. They are most widely used in disposable food containers to single use clamps used in IV lines. Please keep a close eye on everyday objects and you are bound to find them everywhere!
@@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.
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!
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.
@@davidgutierrez8297 Good thing that the design isn't actually meant to be used for plastics, but metals, am I right? The plastic shown is only for demonstration purposes.
Centrifugal clutches has inner shoes made out of friction material for reason: steel shoes and steel drum I suspect would have nice sparks flying all over...
@@davidgutierrez8297 1: injection molded plastic toolboxes use different plastics than this and arent stress tested for over a million uses by firms dedicated to compliant mechanisms 2: he literally showed a metal one right after saying "this ones plastic so its just a model" 3: its a single, relatively small, extruded piece of metal, they showed a picture of it installed on a chainsaw and its just smacked on the outside, itd be the cheapest and easiest thing and to replace it you literally replace exactly one piece of metal, instead of buying and replacing multiple components.
Before I retired in 2009, I was talking with an associate in our testing lab that had worked on the safety and arming mechanisms on a particular nuke, in the conversation I asked about the high order of electronics that must be in those devices, to the contrary he said very simple mechanics and simple electric devices are used to keep reliability high.
I started printing the bistable switch as soon as he mentioned a link to the files, before the video even finished. I'll have haptics soon enough :D edit: just got it off the printer. holy crap it's incredibly satisfying!
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.
I wish you asked the guy more interesting questions. Like whether heat generated by the action is greater than in traditional mechanical hinges (which is super important), or how "a million cycles" compares with industry standards. Because the important thing is to compare, not to just say "uuugh, it's possible!".
And on a switch for example (especially with plastic) doing tests consecutively is going to warm up the plastic and actually make it significantly easier on the product being switched. How many flips would it last under normal circumstances?
This is pretty cool, makes sense for some applications. My major concern would be stress and fatigue issues, of which they are obviously aware, and for which they have done some testing.
A video about 3D printable nanomachines is, somehow, focused on nuclear weapons and sponsored by home security. It's both exciting and very terrifying.
Flexible machines are definitely something that I'm finding really fascinating to follow being developed (alongside any space-related tech...because... *space* ) ! I love the idea of rethinking old views on ideas and revisiting them in the modern world and finding they have way more applications than was previously thought! Moral of the story: *always save your work, people!* 🙌😅
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.
Yeah, cos EVERYONE in Utah MUST wear a suit. Haha. He was probably asked to wear it because he was at BYU, owned by the Church of Jesus Christ of Latter-day Saints, he was asked to adhere to a dress code. None of the students would've been in suits. It's a professional courtesy, imo.
He got away easy as they didn't require him to lose the beard. For an employees not shaving and having long hair is a no-no, maybe other rules apply for visitors.
as a Utahn, here's my take on the first couple seconds of the video: Utah! People working together Utah! What a great place to be. Blessed from Heaven above. It's the land that we love. This is the place! Utah! With its mountains and valleys. Utah! With its canyons and streams. You can go anywhere. But there's none that compare. This is the place! It was Brigham Young who led the pioneers across the plains. They suffered with the trials they had to face. With faith they kept on going till they reached the Great Salt Lake Here they heard the words, "This is the place!" Utah! With its focus on family, Utah! Helps each child to succeed. People care how they live. Each has so much to give. This is the place! Utah! With its pioneer spirit. Utah! What a great legacy! Blessed from Heaven above. It's the land that we love. This is the place Utah! Utah! Utah! This is the place! I definitely wrote this all by myself. I didn't copy and paste it from the first set of lyrics I found.
I have no idea what professors are like at other schools, but I couldn't help but think when he said that, "such a typical BYU professor thing to say..." :D.
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.
@rollout the battle rapper , I wondered if that was what you meant. ( comment and address below by xyz ), I also thought this is pretty unselfish to share knowledge which in turn we also would share
@rollout the battle rapper , I thought that was what you meant ( comment by Johan E.g. ) and I am not surprised that this Man is sharing information with others, to HELP the world bend " together.
Those fatigue tests are so cool, but I always wonder what the margin for error is, since actual use a lot different from the conditions in a fatigue test in terms of intervals between uses and heat/friction accumulation
I'd think the biggest and most problematic difference between fatigue tests and actual use might be forces acting in unintended directions. But they might have taken that into account.
And what about all kind of environemental exposures? like atmospheric chemicals, UVs. I would guess that for such thin flexible area to maintain their properties, they would need to also maintain their perfect molecular structure over time. Isolate the part from its harmful environement might be the bigger trouble.@@Geerice
Robert Szasz Good example. I've been re-using the same Tic Tac container since the mid-1980s and typically consume around 3 boxes per day. (Fresh ones of course, I only re-use the box!) You get about 38 Tic Tacs in each box, so I reckon I've opened and closed 'Old Faithful' around 1.25 million times. That's the great thing about Tic Tacks. 🤓
How cool is that! Actually most materials recover very fast from bending force, where you don't have fatigue or plastic deformation involved. The trick is to design for instance a tool where you can control the direction of the forces involved. If the tool is used as it supposed to be used it can almost last forever. Design and control the forces to work in the right direction and then make sure the design is used correctly. Nice...
I can't believe I have never heard of these before, it's genius! This is just like when I learned about Soft Robotics all over again, but this has immediate and direct applications everywhere in life!
Haha, as a production engineer. Bendy Wizard: You can injection mold it. Me: Oooo, nice. Bendy Wizard: You could even extrude it and chop it. Me: OOOOOOOO

To think that we can take complex mechanical systems and make them compliant using a simple formula is what is really quite amazing. Great video!

This is just like when I learned about Soft Robotics all over again, but this has immediate and direct applications everywhere in life!
Not saying that this isn't cool as hell, but does it really bring that much innovation to the centrifugal clutch that scooters and chainsaws already use? It seems it would be lighter for sure and maybe have cheaper (?) manufacturing costs, but other than that I don't think it would benefit them that much. Still a good take on an established technology.
Lighter weight, better reliability, reduced wear, longer component life and cheaper to boot, Rotax have been using them in their Go Kart engine for a while now, made the old style clutch completely obsolete.

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
Haha I was thinking to myself "if compliant designs are so good, why aren't they used everywhere?". Turns out they *are* used everywhere and I'm just unobservant :)
@@skulleeman Yes They are omnipresent. They are most widely used in disposable food containers to single use clamps used in IV lines. Please keep a close eye on everyday objects and you are bound to find them everywhere!
Yes and many are crappy with the flexible hinges easily overstressed thus failing and breaking off.
@@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.
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!
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.
@@davidgutierrez8297 Good thing that the design isn't actually meant to be used for plastics, but metals, am I right? The plastic shown is only for demonstration purposes.

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.

For example, letting a prosthetic hand have a firm grip on some irregular objects.

dude so humble and chill but also shaping the future lol
this was nice and educational
Those fatigue tests are so cool, but I always wonder what the margin for error is, since actual use a lot different from the conditions in a fatigue test in terms of intervals between uses and heat/friction accumulation
Then actual use would last longer. I guess it's used for minimum rating, but you'd expect it to last much longer.
If you use those Switch 3 cycle a day (on/off) it would last 800+years, 15 a day 100+year, i Wonder performance of traditional switch
I'd think the biggest and most problematic difference between fatigue tests and actual use might be forces acting in unintended directions. But they might have taken that into account.
@Drew Kangaroo Okay, use it 14 times a day then
And what about all kind of environemental exposures? like atmospheric chemicals, UVs.
I would guess that for such thin flexible area to maintain their properties, they would need to also maintain their perfect molecular structure over time. Isolate the part from its harmful environement might be the bigger trouble.@@Geerice
It's hard to believe that thin plastic can hold up that long.....1M cycles?
Probably because friction is reduced, meaning less breakdown.
It's the wonders of Polypropylene!
"Plastic" is a very broad term. There are a lot of different kinds of plastics.
Think about the lid of a tictac container
Robert Szasz Good example. I've been re-using the same Tic Tac container since the mid-1980s and typically consume around 3 boxes per day. (Fresh ones of course, I only re-use the box!) You get about 38 Tic Tacs in each box, so I reckon I've opened and closed 'Old Faithful' around 1.25 million times. That's the great thing about Tic Tacks. 🤓

It’s very important to be flexible in your beliefs.
the only channel to have the sponsors at the end of the video and not in the middle making me want to stop watching the video
How cool is that! Actually most materials recover very fast from bending force, where you don't have fatigue or plastic deformation involved. The trick is to design for instance a tool where you can control the direction of the forces involved. If the tool is used as it supposed to be used it can almost last forever. Design and control the forces to work in the right direction and then make sure the design is used correctly. Nice...
I can't believe I have never heard of these before, it's genius!
