DESIGN NAME: UNAwheel Mini
PRIMARY FUNCTION: Wheelchair Power Addon
INSPIRATION: Independence and freedom of movement are the most desirable features that physically challenged people look for in mobility devices. Manual wheelchairs are lightweight and maneuverable, but it is difficult to drive more than 5 km, using your own hands. Electric wheelchair drives itself, but it is super heavy, hard to carry and to travel with. UNAwheel Mini is a wheelchair power add-on with a whole new concept. It provides freedom of movement with unprecedented lightness.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: UNAwheel Mini is a category-defining product. It uniquely combines a sleek minimalistic design with advanced electric motor and lightweight patented structure. Precise maneuverability, soft suspension, airless tire and powerful motor make driving through city streets, shops and parks comfortable and not exhausting and painful for hands and shoulders. Simply fitting UNAwheel Mini to a manual wheelchair converts it into a power-assisted one, so it brings more enjoyment, mobility and independence.
OPERATION / FLOW / INTERACTION: Connect UNAwheel Mini to any manual wheelchair in 30 seconds and enjoy the freedom of movement on electric power.
PROJECT DURATION AND LOCATION: The project started in April 2016 in Moscow, Russia and finished in August 2018 in Singapore, Singapore, and was exhibited in Rehacare Expo in September 2018, Dusseldorf, Germany.

RESEARCH ABSTRACT: During research period we have tested manual and electric wheelchairs as well as all power add-ons available on the market. About 50% of people on wheelchairs have problems with hands and can't operate with gadgets heavier than 6-8 kg.
We also learned that an average range on a manual wheelchair is just about 2 km/day, for electric wheelchair range triples to 5-6 km/day. It is obvious that electric power brings more freedom and independence.
We came up with the idea to make the lightest power add-on possible with the most advanced technologies.
CHALLENGE: 1. To achieve weight that is acceptable for a person in a wheelchair (less than 8kg).
2. To make connection to a wheelchair in less than 30 sec.
3. Make device compatible with 90% of wheelchairs on the market worldwide.
4. Make driving possible even with weak hands.
