If you really wanted to do this, I reckon the way would be to have one set of magnets on the moving shaft and another set surrounding it, so the the repulsion tends to keep the shaft centered. Then you make the shaft surround taper towards the top, so that the further the pole is pushed in, the closer together the magnets are forced. You should be able to achieve any force curve desired with this setup by making the taper non-linear.
- harshreality 8y agoJust use current designs which, I would think, mechanically constrain the pogo stick except in one direction. Replace spring with powerful magnet (pair), and make sure there's a stop pin or something similar to keep the magnetic pogo stick from disassembling itself. I think you're making things too difficult and expensive if you're trying to magnetically suspend and stabilize the pogo stick in multiple/all directions. Also, magnetic radial stabilization would be stable only in a rough sense. The pogo stick handle would still wobble and be disturbingly/unexpectedly unsteady. I think for pogo sticks you'd really want a mechanically confined, piston-like design. You could still have magnetic stops on both extremes.
- dTal 8y agoAlthough it's an interesting idea, I didn't mean to suggest only using the magnets to center it - I was merely clarifying the geometry. Another advantage of my design is that it allows (requires, in fact) one to use many small magnets in place of a few large ones, which is safer and easier to engineer. But as for expense - I think that once you decide to replace springs with magnets in a pogo stick, you have left the path of economy anyway and might as well go for broke.
