Connection of the prosthetic work-arm. The toolkit was designed to fit this joint.
Example of a fork attached to a prosthetic arm, without the toolkit. As shown in the picture, it is difficult for patients to use these fixed tools. The toolkit solves this problem.

Design of a Co-Creation Toolkit for the Prototyping of Prosthetic Arm Extensions

4 Industrial Design - Master Thesis in association with Ghent's University Hospital and Howest

Design of a modular, open-ended and digitally produced toolkit for the co-creation and prototyping of low-tech prosthetic arm extensions. The designed kit changes the current design process occupational therapists apply with their amputee patients. Thanks to the kit, a co-creation is encouraged and enhanced, as it allows them to easily prototype, test and iterate different assistive, custom-made tools for the patients. Afterwards, the assembled prototypes can easily be reproduced by an experienced craftsman in a more durable material. The testing kit sustains amputee patients in the search of their custom assistive prosthetic extension, to test what they really need and which tools are really useful for them (dimensions, positioning, different tools, etc.). Thanks to digital production, the kit can be shared, adapted and reproduced worldwide.
