I had that on my wish list order from Lindsay Publications before they went under.
This is close to what I've been trying to invent for a long time. They need one more feature, and it would be perfect:Speaking of gears, this video popped up in my YouTube suggestions the other day.
Pretty cool technology, actually.
Damn, that's friggen brilliant man!This is close to what I've been trying to invent for a long time. They need one more feature, and it would be perfect:
As the input torque increases, automatically reduce the gear ratio. As such, it would be a fully automatic continuously adjustable transmission capable of maintaining constant torque on the drive motor regardless of load. That would be super neat.
The idea came from peddling my bike. I hate switching gears -- and the associated ratcheting sound and discontinuous pedal motion (and the trial and error of quickly finding the most comfortable gear).Damn, that's friggen brilliant man!
I had a similar (though way less inspired) idea to incorporate one of those conical variable transmission gears to a bike for that very same reason. But that adjustment for torque idea never crossed my mind. And even though it would require adding some electronics to something like a bicycle it would be well worth it, I think. Just imagine how much easier it would be to transition from downhill to uphill. Plus the little servo could probably be powered directly by the rider's pedal stroke.The idea came from peddling my bike. I hate switching gears -- and the associated ratcheting sound and discontinuous pedal motion (and the trial and error of quickly finding the most comfortable gear).
My vision was that one could adjust the torque at which one wished to pedal, and the transmission would automatically and continuously adjust to maintain that torque -- with the associated pedaling rate increasing or decreasing smoothly as inclination and/or road/trail surfaces change.
No! I want it to be purely mechanical and passive.And even though it would require adding some electronics....
Oh, well yeah, that would be awesome. It's kind of hard for me to visualize just how exactly that would work though. I'll see if I can find some videos on that sort of thing and maybe I can understand what you mean a little better. Either way, it's a good idea.No! I want it to be purely mechanical and passive.
Back to the video: if he can add a spring loaded actuator to the adjustment ring, with a lever that moves as a function of torque, this would be a perfect solution.
It's not something I would strive to patent. But I cannot see why an adaption that is bicycle compatible would be outright rejected by the USPTO, especially if the adaptation is unique wrt prior art.Unfortunately that probably also means you were beat to the patent office.
