'Polymagnet' anti-gravity seats, beds and neck braces

Author: @robdubois

Description of Idea:
I have a spinal cord injury which leaves me in pain with any bumps or jarring to my head. My condition is not treatable. Gravity is my enemy. Can we develop anti-gravity neck-braces, car seats, and beds using polymagnets - http://www.polymagnet.com/polymagnets/ ?

I would like to use a polymagnet anti-gravity seat in my car and with my mobility scooter. Typical cars and mobility scooters are too painful for me. I would also like to have an anti-gravity polymagnet bed or mattress or blanket which allows me to ‘float’ to alleviate pain while sleeping. An anti-gravity neck brace would help me while walking. I wish to develop a neck brace that supports the head at the cheekbones, not below the jawbone. That would allow for talking, eating, and drinking while wearing the brace, while extending the time which the device can be worn.

If we can develop an anti-gravity polymagnet seat, it can be sold to truckers, travelers, and anyone wishing a smoother ride in their vehicles. If we can develop anti-gravity polymagnet beds, they could be sold to hospitals, care homes, mobility recovery facilities, and homes for seniors.

I have a specialized mobility scooter, but it’s too jarring as is. I would like to see about modifying my scooter for my needs.

Is anyone experienced with polymagnets?

I think this is a REALLY great idea. I did some reading into Polymagnets, really interesting.

I imagine the ‘spring’ characteristic of a programmed magnet could be used as a ‘magnetic shock absorber’ integrated into a seat cushion. - https://vimeo.com/107166551

I am not sure as to the working force of these magnets, but I have reached out to the company to see what they can supply.

Here is some information form the Polymagnet vendors:

Spring Polymagnets are the most difficult to justify because there are many effective spring designs, configurations & materials. Other Polymagnet functions don’t viable alternatives.

Here are characteristics of Spring Polymagnets:

  • They offer high repulsive forces only at small gaps (0-2mm)
    • Conventional Neo magnets offer much larger ranges with lower spring constants
  • They are brittle & can crack easily if impacted
  • They must be mechanically aligned to prevent them from moving side to side & attaching to an opposite polarity region.
  • Neodymium magnets & therefore Polymagnets are rather expensive because you need a matching set of mechanically aligned magnets
    • The cost would be in the range of $0.75 to $5.00 per square inch
  • Polymagnet are useful if you need a custom & precise spring curve with very small displacement (0 – 2mm travel)

If you are still interested in their unique capabilities, then you should order some eval samples to conduct feasibility tests - https://catalog.polymagnet.com/polymagnet-products/spring.html & https://polarstarmagnetics.com/spring/

So I think a magnetic (non mechanical) solution is still viable just perhaps with conventional magnets.
