ChairMate Evac Unit

Chair mate Evac Unit, PDG Ltd Design Consultancy, Derby, Nottingham, Industrial Product Design

When KTP UK were looking for a company to work on the production design of their ChairMate wheelchair evacuation unit, they selected PDG. Designed to enable wheelchair users to be evacuated down stairwells in their own chair in a controlled manner, the concept is innovative and potentially life saving.  Starting with an existing prototype, we re-engineered various areas of the unit to improve its performance and make production straightforward and consistent.  The handle fold/unfold and lift mechanism received particular attention.  The project met its goals and was successfully taken into production – a great example of functional product design.

  • Re-engineering of existing prototype using 3D CAD
  • Full 2D drawing pack for manufacture
  • Support to client during prototype build
  • Support during pre-production run
