Towards a Product Service System Framework for Lower Limb Prosthetic Devices

Abstract

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

A multi user‐centred design approach framework to develop aesthetically pleasing and sustainable OTCP packaging

“…Both surveys were tested for reliability and validity, using IBM Statistical Package for Social Sciences software. 60 The Person's coefficient for the consumers' and the pharmacists' survey were 0.984 and 0.868, respectively. The Cronbach's alpha score of the consumers' survey was 0.903 and 0.986 for the pharmacists' survey.…”

“…The OTCP packaging development stakeholders emphasised the importance of striking a balance between sustainability and aesthetics. Therefore, it is essential to consider a multidisciplinary approach to OTCP packaging design such as those in previous studies 61–70 . However, none of these design support systems are related to packaging, so the critical review concentrates on design systems to support packaging design.…”

“…This allows for a quantitative analysis using the IBM Statistical Package for Social Sciences software. 60 A thematic analysis was carried out on the transcripts, using the QSR International's NVivo 12 software. 58 The Intercoder Reliability was calculated to establish trustworthiness in the qualitative results, following Nowell's et al model.…”
