Why Machines That Bend Are Better

  • Compliant mechanisms have lots of advantages over traditional devices. SimpliSafe is awesome security. It's really effective, easy to use, and the price is great. Check out SimpliSafe here: https://simplisafe.com/veritasium I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell: https://www.compliantmechanisms.byu.edu At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms. What I learned about compliant mechanisms I summarize in the 8 P's of compliant mechanisms: 1. Part count (reduced by having flexible parts instead of springs, hinges) 2. Productions processes (many, new, different enabled by compliant designs) 3. Price (reduced by fewer parts and different production processes) 4. Precise Motion (no backlash, less wear, friction) 5. Performance (no outgassing, doesn't require lubricant) 6. Proportions (reduced through different production processes) 7. Portability (lightweight due to simpler, reduced part count designs) 8. Predictability (devices are reliable over a long period of time) Special thanks to Patreon supporters: Donal Botkin, James M Nicholson, Michael Krugman, Nathan Hansen, Ron Neal, Stan Presolski, Terrance Shepherd Animation by Alan Chamberlain

    Mechanical systems can be much more reliable than electronic ones. I wouldn't be surprised if nuclear bombs have many mechanical devices in them.
    I heard of a missile that used a spring-wound gyroscope instead of motor driven. It didn't use a battery that could go bad or need to be replaced. It only needed to run for a minute or so, so using mechanical energy made since. It could be stored for years without worrying about replacing the battery.

    super foward thinking applied materials science.. wonder what happens when i stick my finger in that there
    but anyway i thought the problem wasnt 'how can we get flexible materials into things/ how can flexible material work for us' but ' how can we make flexible materials reliable and what engineering and material science is required to produce the material that can do this and withstand and tolerate it'

    Its great to see people are starting to use flexibility as an advantage in designs (even though I personally never use it). My concern is that when using flexible materials in designs like the WMD activation device, you would have to really see how long thin pieces of whatever material they would use can last without input for years. From my experiences, when things are just sitting out, events in a temperature controlled room, they're going to degrade, plastics especially.

    I'm not trying to sound like an ass but that switch test is definitely flawed. Sure you can take a freshly molded/printed plastic switch and it works as he said over a million times without breaking, but that was also in an environmentally controlled room. I would like to see how well it works after going through heating and cold cycles, in different humid environments, and after just sitting for extended periods of time. If it can do all those better than traditional switches then you've got yourself a good design.
