Design and development of a standing assist device to help people with motor deficiency

Oral presentation.In order to respond the needs of people suffering from muscle weakness due to age or disabilities that make sit-tostand a difficult functional task, the knowledge and the development of new devices that answer those needs of the patients it is revealed of crucial importance. This manner, the present work intends to design new standing assist device to help people with motor deficiency.Like this, along this paper they are referred the most relevant pathologies, which affect the autonomy of the patient’s standing, as well as some existent devices in the market. Based on the characteristics of these devices, this research was performed with the main objective of finding the most appropriate actuation system to better fulfill the specifications of this research work. Furthermore, it was made the analysis and discussion of the performance specifications, essential stage in the design process of the standing aid device for this to assure all the demanded requirements. Afterward, they are pointed some possible solutions, in the sense of creating more and better on behalf of the patient's need. Of among the several possible solutions, it was selected one, being preceded the analysis of the actuation system, mainly regarding to the trajectory obtained by the mechanism designed. It was being later developed a model for the simulation of the mechanical system of aid standing. This paper discusses and analyses, in detail, the mechanical design carried out (dimensioning, technical drawings and assembly schemes, manufacturing techniques)
