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:

    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)

    This was one of the most interesting episodes that you've ever made!

  • If you thought this was interesting, look up the subject of human factors. If you want a specific category to peruse, try ergonomics.

    I was thinking the whole time how I'd like to 3D print some of this stuff and then he's like "here you can print these and PLA". Awesome.
