Manufactura y pruebas de una silla de ruedas bipedestadora destinada a personas adultas con discapacidad física a nivel de paraplejia o con problemas de movilidad de uso en interiores para el grupo de investigación y estudios de bioingeniería de la Facultad de Mecánica ESPOCH

Abstract

The objective of this work was to build and test a standing wheelchair for adults with physical disabilities at the level of paraplegia, or mobility problems for indoor use. The manufacture was carried out considering the previous theoretical study carried out by Mario Herrera in which the mechanical design and its respective simulation for the validation of the results obtained stand out. Subsequently, the constructive feasibility was evaluated through the analysis of the design for manufacturing, some elements of the stander were restructured seeking to optimize the weight and reduce oversizing, the selection of the material was justified from the technical-financial and ergonomic point of view. In addition, applying the AISC-360-16 code, the welded joints were sized. Standard elements such as: actuators, wheels and elements of the electronic control system were also selected. Subsequently, the construction process was planned through tables, flowcharts and manufacturing process sheets were prepared. In the latter, important factors such as: machinery, control tools, welding characteristics and sheet metal folding stand out. Finally, the prototype was obtained, and its functionality was evaluated through direct experimentation with users. Functional aspects such as: electrical response, ascent and translation times were evaluated, as well as ergonomic aspects such as: adaptability, comfort, and quality. It was finally concluded that the prototype works adequately for the purpose for which it was designed and provides sufficient characteristics to satisfy the user's needs. It is recommended to analyze possible improvements in factors such as: materials, reduction of actuators and facilitation of transport and storage of the mechanism.
