Design colaborativo e o processo de desenvolvimento de dispositivos para reabilitação do membro superior / Collaborative design and the device development process for upper limb rehabilitation

Casagranda, Kelin Luana January 2018 (has links)
As órteses de membro superior são dispositivos que auxiliam na reabilitação da mão e que tem como objetivo estabilizar, imobilizar, prevenir e corrigir deformidades, melhorando assim a função. O processo tradicional de confecção de órteses é realizado por meio do uso de termoplásticos de baixa temperatura, material moldado diretamente sobre o membro do usuário, sendo neste processo relatados inúmeros problemas, que envolvem desconforto durante o processo, alto custo e baixa adesão do paciente ao uso. O presente trabalho, portanto, teve por objetivo propor a construção de um framework com abordagem metodológica projetual para a produção de órteses de membro superior baseada no processo de design e design colaborativo, com auxílio de recursos de fabricação digital, como digitalização tridimensional e manufatura aditiva (impressão 3D). Através de uma pesquisa exploratória, foram discutidas questões relativas ao projeto de órteses de membro superior (MMSS) pela forma tradicional, utilizando termoplástico de baixa temperatura, e questões do processo de design no desenvolvimento de novos produtos a serem aplicadas do desenvolvimento de órteses utilizando a manufatura aditiva A coleta de dados contou com a participação dos principais personagens envolvidos no processo, usuários de órteses, Terapeutas Ocupacionais e Designers. Com base na técnica de card sorting e entrevistas, foi elaborado um framework da abordagem projetual para a criação de órteses utilizando processos de fabricação digital, de forma colaborativa. O framework ainda foi aplicado no desenvolvimento de uma órtese a fim de avaliar os resultados e melhorias levantadas durante a fase de entrevistas com profissionais e usuários. Ao final do processo, obteve-se uma órtese funcional em que foram atendidos os requisitos necessários para a produção de uma órtese levantada pelo trabalho, além da criação do framework servindo como um guia para o desenvolvimento de órteses utilizando a manufatura aditiva. / Upper limb orthoses are devices that assist in the rehabilitation of the hand and that aim to stabilize, immobilize, prevent and correct deformities, thus improving the function. The traditional process of making orthotics is accomplished through the use of thermoplastics of low temperature, molded material directly on the member of the user, being in this process reported numerous problems, that involve discomfort during the process, high cost and low adhesion of the patient to the use. The present work, therefore, aimed to propose the construction of a framework with a design methodological approach for the production of upper limb orthosis based on the process of design and collaborative design, with the aid of digital manufacturing resources such as three - dimensional digitization and additive manufacturing (3D printing). Through an exploratory research, questions regarding the design of upper limb orthoses (MMSS) in the traditional way, using low-temperature thermoplastic, and design process issues in the development of new products to be applied in the development of orthoses using the additive manufacture The data collection was attended by the main characters involved in the process, users of orthoses, Occupational Therapists, and Designers. Based on the technique of card sorting and interviews, a framework of the design approach for the creation of orthoses using digital manufacturing processes was developed in a collaborative way. The framework was also applied in the development of a bracing in order to collaborate with the results and improvements raised during the interviews phase with professionals and users. At the end of the process, a functional orthosis was obtained, in which the necessary requirements for the production of an orthosis were obtained by the work, besides the creation of a framework serving as a guide for the development of orthoses using the additive manufacture.

Digitisation of the splinting process : exploration and evaluation of a computer aided design approach to support additive manufacture

Paterson, Abby January 2013 (has links)
Upper extremity splinting is a popular treatment method for a range of conditions, such as rheumatoid arthritis. The intent of this treatment approach is multifaceted, but fundamentally, the provision of tools to enable and encourage patients to carry out everyday activities and to improve their quality of life is paramount. However, the aesthetic and functional limitations of wrist immobilisation splints demonstrate various weaknesses in terms of wear duration and frequency. Patient compliance is often compromised due to a number of factors, including the perceived stigma associated with assistive devices. Additive Manufacturing (AM) has proved its worth in a number of applications relating to the design of assistive devices; builds of complex, bespoke fitting geometries make AM an ideal fabrication method for upper extremity splints. However, recent advances in system technology to enable multi-material builds have been limited in this field, and a distinct need for a specialised three-dimensional (3D) Computer Aided Design (CAD) software approach is required to allow therapists to design splints for AM. Furthermore, the intent to keep practising therapists at the forefront of splint prescription is of utmost importance. This research proposes a digitised splinting approach, specifically through development of a 3D CAD software strategy to allow therapists to capture their design intent without compromising creativity. Furthermore, the approach proposes the exploration of AM build capabilities by allowing the integration of more creative features, such as aesthetically pleasing lattice structures for increased skin ventilation. The approach also proposes the integration of multiple materials to replicate and improve upon current splint design and fabrication practises. The approach therefore explores an exciting new paradigm for upper extremity splinting, the driving characteristics of which have not been proposed before as a collective medium. This research describes the feasibility of capturing therapists design intent in a 3D CAD virtual environment, whilst capturing therapists opinions of the approach with suggestions for future research and development. Results concluded that therapists were excited by the proposed transition in AM splinting, but that significant development is required elsewhere to establish a supporting infrastructure in order to make the approach a viable option in future upper extremity splinting.
