Patient transfer: design and development of a ceiling track hoist

Abstract [en]

Providing assistive devices for disabled and elderly people in order to simplify their lives and increase their independence is an important task in today’s care sector. RoMedic AB is a complete supplier of patient transfer devices but would like to increase their competitiveness on the ceiling track hoist market by the development of a new ceiling track hoist that should be stronger, faster and include more features than existing solutions. The project can be divided into 4 stages: starting with the design space exploration (DSE) stage were the actual needs for all important stakeholders were identified and by various methods translated into requirement specifications. After the DSE stage, the concept design stage were carried out where different concepts were developed and evaluated in order to find the most competitive solution. This led to the detail design stage where the chosen concept was realized and manufacturing specifications for all parts of the system were developed. In the last step, a fully functional, full scale prototype was built, tested and evaluated. Hence, the project resulted in a prototype along with complete CAD data and manufacturing specifications. In comparison to RoMedic AB’s existing comparable ceiling track hoist, the team developed a more powerful hoist which is capable of lifting 25% more at up to a 200% faster lifting speed. This was achieved while keeping the size, weight and cost of the hoist at a similar level as the comparable solution and was possible due to, among other things, the design of a brand new drive train. Beside these performance factors, a number of innovative features have been developed and the project will continue throughout 2010 with further evaluation and development of the hoist, with the goal to release the product to the market in the close future.
