Resumo/Abstract

This paper aims to develop the conceptual design for a feeding and writing auxiliary orthosis. Assistive Technology (AT) is a multidisciplinary area of knowledge, which prescribes equipments and strategies, assisting the rehabilitation of people with different difficulties. The development of AT projects includes the collaboration between engineering, healthcare professionals and patients, obtaining viable solutions that satisfy the users’ needs and support the mechanical requests. The informational design is the first step to obtain a degree of innovation and it delivers a report, which describes commercial products, patents, technical solutions, and aspects that must feature the solutions. The second step, the conceptual design, includes the conception of ideas from technical and functional inspirations and from creativity tools. Thus, the viability design was developed for a hand-wrist orthosis for children with motor difficulties, using design methodology tools as the Quality Function Deployment (QFD); Material-Energy-Signal flow (MEI); functional diagram; morphological diagram; Computer Aided Design (CAD); and a 3D printed mock-up. The usage of these techniques has allowed a better communication between the technical team and the users, enhancing the chances of meeting their needs. The preliminary results indicate the potential usage by occupational therapists, healthcare professionals, besides a number of benefits as physical, mental and wellness improvements. The mock-upmust be tested and validated in future studies, applying the Single Case methodology.
