How Flexible Machines Could Save The World

Compliant mechanisms have plenty of advantages over conventional devices. SimpliSafe is terrific security. It is truly successful, simple to use, and the cost is good. Check out SimpliSafe here:

I visited the Compliant Mechanisms Research group at Brigham Young University and talked to Professor Larry Howell:

At the above link, you can download 3D-print files to make some of the items in the video clip, 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 (lessened by having lithe parts rather than springs, hinges)
2. Productions processes (many, new, different enabled by compliant designs)
3. Price (lessened by fewer parts and different production processes)
4. Precise Motion (no backlash, less wear, friction)
5. Performance (no outgassing, does not require lube)
6. Proportions (diminished through different production processes)
7. Portability (lightweight on account of simpler, diminished part count designs)
8. Predictability (devices are trustworthy over a long period of time)

  1. A nail clipper made from a compliant mechanism. The future is near.

  2. Dude, what is up with this collar of yours? =)

  3. Who are these shy lads to the left at 1:36 ?

  4. Great! Now make a mechanism that will stop mah penis from getting caught in mah bicycle chain

  5. Oh yeah good idea let’s make more plastic that will save the world guys

  6. Kinda expected comments theorizing about “possible ways of hacking this safety mechanism” and other people yelling at them: “don’t give out ideas to terrorists”, and so on.

  7. It terrifying to know that new clear weapon can go off acidently.

  8. Like the video, just hate the cult involvement

  9. “Brigham Young” University, so that’s why the guy is so nice… 😂
    Where are the golden plates at professor??

  10. 4:15 epic Yoda laugh.
