This paper introduces a design support tool based on the axiomatic model systematically transform requirements into functions technological capabilities. The results from an evaluation implemented prototype in field medical device demonstrates its usefulness selecting most suitable candidate manufacturing for given...

Abstract In recent years, studies have proven that conformal cooling channels (CCC) in an additively manufactured mould result a more efficient and effective injection moulding process. This can be achieved since CCCs are designed to follow the contour of part being moulded so surface is equidistant from channel at all points. However, no were found which explored combined effect material thermal conductivity varying designs on performance sustainability point view. Within this context,...

Abstract Despite technological and medical advances, amputations continue to increase. Amputees face significant challenges when acquiring using prosthetic devices, which are made worse as their emotional needs, aspirations, mobility, prosthesis requirements problems change over time. These require custom solutions for each individual amputee, a fact that current amputee centered services tend ignore. The work reported in this paper contributes an AI based Prosthesis Development Service...

Additive Manufacturing (AM) facilitates product development due to the various native advantages of AM when compared traditional manufacturing processes. Efficiency, customisation, innovation, and ease modifications are a few AM. This process can therefore be applied fabricate customisable devices, such as bespoke interactive devices for rehabilitation purposes. In this context, two-day workshop titled Design Manufacturing: Future Interactive Devices (DEFINED) was held discuss design issues...

Abstract Amputees face a number of challenges when acquiring and using prosthesis, with major issues being the cost device, time it takes for their custom prosthesis to be developed delivered, as well they get regularly serviced maintained. The other stakeholders involved, including prosthetists standard systems manufacturers, have difficulty collectively handle so many that occur different amputees. To address these challenges, our research reported in this paper contributes an approach how...

Abstract There is a need to cost-effectively produce polymer components with meso/micro-scale internal geometries high replication accuracy without the use of post-processing steps. A possible process chain such hollow features by combining 3D printing (3DP) and micro-injection moulding (MIM) processes. To date, no studies were carried out explore feasibility chain. Consequently, this experimental study investigated 3DP lost-cores that are over-moulded using MIM process. The first step...

Abstract Understanding the viewpoint of clinicians in a healthcare setting is vital task to comprehend success patients undergoing physical rehabilitation. Addressing user experience an essential activity which designers undertake when formulating product specifications at early stages design. The involvement during use-phase influences progress and achievements attained by throughout their rehabilitation journey. Several (n=16) were asked participate qualitative study evaluate performance...

Abstract Amputees face challenges with prosthesis such as cost, long delivery periods, well social discomfort. Simultaneously, the prosthetists and manufacturers have a difficulty to handle diverse issues. We thus contribute Prosthetic Life-Cycle Service System (ProLiSS) Framework, prescribed involve amputees in different life phases. From an evaluation of ProLiSS, we conclude that it influences how prosthetics need be designed is beneficial perform further research provide systematic,...
