Diseño y construcción de un andador plegable con asiento, de cuatro ruedas con sistema de frenado para el desplazamiento autónomo de personas con problemas de movilidad reducida

Abstract

In Ecuador people with reduced mobility problems according to the INEC are found in the older adult population with a percentage of 45 percent which leads to seeking alternatives for a decent life, the objective of the project lies in the autonomy that people require to move from one place to another, through the proposal of a folding walker with a seat, four wheels with a braking system, to avoid possible accidents, providing security to the user. For the development of the project, a quantitative approach methodology was used to evaluate the large number of numerical values, which are necessary for the design of the mechanism, which allowed the selection of the appropriate material for its construction, it is also of an exploratory nature since models of walkers were sought to determine the dimensions from an established model allowing to identify the degree of resistance and its operation, an anthropometric analysis was also carried out to establish the regulation measures for the user, such as the width of the hips to establish the folding width of the seat of the walker. In addition, the walker complies with the parameters and the materials duly selected, functional tests were carried out on 5 people who were satisfied and benefited from the product since they were able to move from one place to another safely, according to the results their well-being improved, finally it turned out that it is easy to handle for most users and it does not take up much space so it can be stored anywhere.
