conceived by london-based designer patrick hyland, ‘synergise’ is a mechanical system which allows wheelchair users to negotiate commonly faced issues; cambered surfaces. these affect propulsion as the wheelchair would veer towards the road by gravity. as the user has to brake on one side and propel on the other, the momentum is affected,where increased friction leads to a higher energy consumption.

all of these physical issues make the energy required to cover a certain distance twice as taxing compared to the energy used by able-bodied people travelling the same distance. ‘synergise’ allows wheelchair users to negotiate angled surfaces with reduced friction and increased efficiency over endurance with reduced risks of RSI (repetitive strain injury) to the user and its well-being.

  • this is simply brillant!
    is it a working prototype or is it a model?
    A video should be nice to look at.

    Thank you for you idea, hope you’ll put it in production!

  • I can’t belive it, I have just about the same sketches of that kind of wheelchairs from about year ago. Just putted that project on a side to improve the idea when I catch a time!
    This is just proof that a lot of people think similar when meeting the human needs.
    Congrats on your design!

  • Really? Who does all the work retracing and putting it back together? The handicapped person? You’re kidding are you not?

    NelsonDReyes Architect says:
  • Why would one want to retracing and putting it back together? Think again! You just have to do it once. Smart ass!

  • Brilliant

  • Looks intriguing BUT, it makes the chair a bit wider (2 to 3 inches?) and my chai barely fits through some of our home doors now. My seat is only 16 so I am on the small side. Anyone with narrow doors in the house cannot use it. Bummer. Mechanically it looks excellent. Am I correct that it push propels?

    Tetracyclone says:
  • Excellent and useful- I think it would sell very well. Considering extra width is very minor. If using that product rather than hand rims- and hand rims are an inch or two; you no longer need hand rims and are free to remove them. Doing that would subtract a few inches for this product. I use a wheelchair and my hand angle with standard rims is painful and difficult. This product is a “normal” relaxed angle- like mountain bike handlebars. Fascinating!

  • I like it.I think , this is a good idea
