Conceptual Design of a Multifunctional Aquatic Crutch for People with Reduced Mobility

Many people with mobility problems rely on the use of crutches for a safer access to bathing activities in pools or beaches. However, the number of models of crutches designed for aquatic environment currently existing in market is scarce, and at the same time all models are quite alike. This article describes a conceptual design of a multifunctional aquatic crutch, designed to allow a dual use: on the one hand, it provides stability and support in the process of entry and exit of water, and on the other hand, it serves as a support float while performing therapeutic exercises or enjoying the bath. User Centred Design approach and benchmarking techniques were used to create the new crutch model and to compare existing models, respectively. Then, Solidworks® 2020 software was used for design purposes, while CES EduPack® 2010 was the software used for selecting the manufacturing materials. The final design equals and even improves the features of the rest of products currently present on the market, in terms of resistance to both corrosion and UV radiation, as well as creep, breakage and fatigue.
