Análisis funcional en el diseño y desarrollo de un accesorio dedicado a la manipulación de teléfonos inteligentes y su influencia en el síndrome del Tunel Carpiano.

Abstract

This research aims to carry out a functional analysis in the design and development of a product or accessory for the manipulation of smartphones that reduces the possibility of complications of the problem in the carpal tunnel due to the manipulation of these devices so used today, at the time of use the selected prototype and that its operation can be revalidated by myoelectric signals. In the first stage, the method presents three different designs modeled in specialized 3D software called CATIA V5, dedicated to managing the life cycle of new products. In the PLM process of the industrial design, the manufacture of the three designs was obtained by performing a posture analysis with the simulation of one of these designs, such as the AV3 prototype, this being the selected version of the CAD - CAM - CAE. The AV3 version of the prototype supports the three aspects expected in this study, the first and most important the physiological aspect; Due to the fact that it allows to use the telephone in a healthy way, minimizing the tension of the carpal tunnel, the functional analysis was validated by making comparisons with the results of the different superficial electromyography shots applied to the hand of a patient, holding or manipulating each of the accessories (AV3 vs current market accessory) and the smartphone, the second technological aspect; because the prototype offers a safe charging station or stage and finally the functional aspect; because it is an innovative prototype and has versatility in the use and handling of Smartphones as a new product.
