Bachelor Assignment

The goal of this project was to conduct a comprehensive risk analysis of J58s manual stand-up wheelchair, Ezer 1.0, in accordance with international safety standards for medical products and manual wheelchairs, and to apply a design engineering approach to mitigate the most severe hazard.

The analysis phase revealed that the most critical hazard during use of the wheelchair, was the risk of users forgetting to attach the chest belt when activating the standing position. Multiple medical reports involving similar wheelchairs, had shown this issue to result in severe injury.

To address this, a safety mechanism was designed and integrated into the chest belt buckle, preventing the user from activating the standing mechanism if the belt is not secured. This design solution successfully mitigated the identified risk.
