Resumo
O presente trabalho de pesquisa consiste na concepção de um veículo motorizado elétrico modular de acoplamento universal em qualquer modelo de cadeira de rodas mecanomanual. Trata-se de um equipamento eletro-mecânico, disponibilizado em forma de acessório, com estrutura física simplificada e alta tecnologia eletrônica aplicada capaz de proporcionar ao cadeirante maior liberdade de movimentação sem desgastes físicos. A aliança entre o design inclusivo e a área médica pode se relevar um passo importante na obtenção de produtos direcionados para as necessidades reais de pessoas com condições físicas e psíquicas particulares, melhorando o seu bem-estar e capacidade de execução de atividades no dia a dia. Desta forma, o presente trabalho é direcionado pelos fundamentos do design inclusivo com o principal ponto focal no usuário, mas que apresenta outros dois importantes pilares adotados em sua metodologia de desenvolvimento, sendo eles, o benchmarkig e o estudo de Normas Técnicas aplicadas no desenvolvimento de equipamentos assistivos. São apresentadas as etapas de desenvolvimento, ensaios com base em Normas Técnicas e teste de usabilidade. Busca-se evidenciar todo o processo de design de equipamento, assim como o estudo teórico de estabilidade e montagem do protótipo funcional. Os ensaios baseados na Norma Técnica ABNT NBR ISO 7176 permitem o entendimento do comportamento dinâmico e funcional do protótipo em termos de estabilidade estática, eficácia dos freios, consumo de energia, velocidade máxima, aceleração, desaceleração e capacidade de transposição de obstáculos. Por fim, discute-se a análise de resultados dos ensaios junto aos resultados teóricos calculados e pré-requisitos estabelecidos.
The thesis consists in the conception of a modular electric motor vehicle that can be attached in any model of standard wheelchair. It is an electro-mechanical equipment, available as an accessory, with a simplified physical structure and high applied electronic technology capable of giving the wheelchair greater freedom of movement without physical wear and tear. The union between inclusive design and the medical field can be an important step in obtaining products aimed at the real needs of people with particular physical and psychological conditions, improving their well-being and ability to do their daily activities. In this way, the thesis is guided by the fundamentals of inclusive design with the main focal point in the user, by the way presents two other important pillars adopted in its development methodology, being the benchmarkig and the study of Technical Standards applied in the development of Assistive devices. The stages of development are presented, tests based on Technical Standards and usability testing. The aim of this work is to demonstrate the whole process of equipment design, as well as the theoretical study of stability and assembly of the functional prototype. The tests based on the Technical Standard ABNT NBR ISO 7176 allow the understanding of the dynamic and functional behavior of the prototype in terms of static stability, brake efficiency, power consumption, maximum speed, acceleration, deceleration and obstacle transposition capacity. Finally, we discuss the analysis of the results of the tests together with the calculated theoretical results and established prerequisites.
