MANDY'S CHALLENGE

Mandy is a quadruple amputee with two prosthetic arms and legs. Mandy was a Need-Knower in both the 2016 and 2017 Makeathon with two unique challenges. Mandy’s challenge for TOM @ University is based around her wheelchair. Whenever she uses her wheelchair in the garden or out on a dirt road, her husband needs to clean all 6 wheels manually with a brush. For many permanent wheelchair users, this simple task would be made extremely difficult, especially without the appropriate support. Mandy would like to create a wheelchair docking station, akin to an automatic car wash, where you could roll in the wheelchair, have the wheels cleaned and then roll straight off again. 

THE SOLUTION

The device is designed to enable a motorised wheelchair to drive up onto the device and stop so that the centre drive wheels are located between the central drive rollers and the
smaller non-drive wheels of the wheelchair are located between the front and back rollers of the device. The user slowly drives backwards on the rollers, the drive wheels of the chair cause the central rollers to rotate; these are connected with sprockets and chain to the front and back rollers that transfer drive to the non-drive wheels of the chair. In this way the device uses the wheelchairs own power drive to rotate all wheels against both static and rotating brushes to clean the wheels of the wheelchair.
