Resumo
Muitas das cadeiras de rodas utilizadas por animais domésticos com problemas locomotores são feitas a partir de materiais improvisados, como canos, rodinhas de brinquedos e diversos materiais reciclados, devido, sobretudo, aos seus baixos custos. Porém, esses aparelhos improvisados podem ter desempenho comprometido e não atenderem às necessidades do animal, até mesmo causarem lesões por não serem devidamente adaptados. Uma das finalidades do Design é solucionar problemas de projeto, como também otimizar o produto e o seu processo de produção, podendo, dessa forma, auxiliar no desenvolvimento de equipamentos para cães com problemas locomotores, cuja área ainda carece de estudos. O objetivo da presente pesquisa foi propor as diretrizes necessárias para a construção de cadeiras de rodas eficientes para cães com problemas de locomoção nos membros pélvicos a partir de tecnologias de Prototipagem Rápida, as quais proporcionam a obtenção de peças com exatidão geométrica ou discrepância desprezível, assegurando maior conforto e melhor funcionalidade, com menores tempo de produção e custos. Esta pesquisa foi dividida em duas fases: (i) pesquisa teórica bibliográfica e (ii) pesquisa prática experimental. Na teórica, foram feitas revisões bibliográficas a respeito dos problemas locomotores em cães e sobre as tecnologias de Prototipagem Rápida, suas aplicações e estado da arte. Já na fase experimental, uma metodologia projetual adaptada de Munari (1981) foi utilizada para confecção e análise de aparelhos existentes, os quais contribuíram para a proposta de um modelo que suprisse as necessidades dos modelos analisados. A cadeira de rodas projetada, embora tenha atendido às principais expectativas, necessitou de alguns ajustes e alterações estruturais, podendo ser considerada um primeiro passo para o desenvolvimento de modelos futuros. Em vista disso, através das informações obtidas na produção desse aparelho, como também os dados coletados a partir dos outros testes e análises, foi possível elencar as diretrizes fundamentais para a produção de cadeiras de rodas eficientes, com peças impressas em 3D, para cães com problemas locomotores nos membros pélvicos.
Many wheelchairs used by domestic animals with locomotion problems are made from improvised materials such as pipes, toy wheels and many recycled materials, due to their low costs. However, these improvised devices can compromise performance and may not attend the needs of the animal, even causing injuries for not being properly adapted. One of Design's purposes is to solve problems within projects, as well as to optimize the product and its production process, and, in this way, to aid in the development of this kind of equipment for dogs with locomotive problems, whose area is still lacking in studies. The present research objective was to propose the necessary guidelines for the construction of efficient wheelchairs for dogs with locomotion problems in the pelvic area using Rapid Prototyping technologies, which provide pieces with geometric accuracy or negligible discrepancy, ensuring greater comfort and better functionality to the dog, with shorter production time and lower costs. This research was divided into two phases: (i) theoretical bibliographic research and (ii) experimental practical research. In the theoretical phase, bibliographical reviews were made regarding the locomotion problems in dogs and about Rapid Prototyping technologies, their applications, and state of the art. In the experimental phase, a design methodology adapted from Munari (1981) was used for the confection and analysis of existing devices, which contributed to the proposal of a model that would attend the needs of the models analyzed. The designed wheelchair, although had met the main expectations, required some adjustments and structural changes, and could be considered a first step for the development of future models. Consequently, through the information obtained in the production of this device, as well as the data collected from the other tests and analyzes, it was possible to list the fundamental guidelines for the production of efficient wheelchairs with 3D printed parts for dogs with locomotion problems in the pelvic area.
