The invention could help with anything from personal care to hobbies and household chores and the end result should be an improvement in the quality of life and independence of disabled people.
Areas where a clever innovation could help include preparing a meal, eating and drinking; gardening, hobbies or leisure; tasks around the house; personal care; interacting and communication; memory or mood; dressing; shopping.
Disability Rights UK have jointly launched the contest with Irwin Mitchell, which is providing funding up to the value of £10,000 to contribute towards the development of a prototype of the winning entry.
The overall winner will also receive £500 in gift vouchers. The other age category winners will receive £150 in gift vouchers.
There are two age groups: 17 and under, and over 18. You will be able to download an application form from the Irwin Mitchell website.
To enter the Design for Life competition, you will need to describe the problem you are looking to overcome, and give a description of your invention or bright idea, with pictures if you wish.
Closing date for Design for life is December 1, and entries will be judged on the merits of the invention, rather than the quality of the submission.
Judges will be announced shortly, and details of the winner will be published in January.
