Design och utveckling av ett avtagbart elektronik hölje för en smart textil

Stark, Sara LU (2026) MMKM05 20261
Innovation
Abstract (Swedish)
Detta examensarbete genomfördes i nära samarbete med Donya Tech AB, som
utvecklar ett smart graviditetsband som följer fosterrörelser. Syftet med arbetet är
att utveckla ett avtagbart elektronikhölje som ska integreras i plagget och skyddar
den elektronik som används.
Arbetet har utgått från Ulrich och Eppinger´s produktutvecklingsprocess i
kombination med Rapid Prototyping, vilket möjliggjorde en strukturerad och
flexibel process. Rapid Prototyping har varit en viktig del i processen eftersom flera
delar av produkten utvecklats parallellt med andra på Donya Tech, vilket krävde
snabba iterationer och tät återkoppling.
Genom insamling av kundbehov, benchmarking, externa och interna sökningar,

delar av produkten utvecklats parallellt med andra på Donya Tech, vilket krävde
snabba iterationer och tät återkoppling.
Genom insamling av kundbehov, benchmarking, externa och interna sökningar,
genererades ett antal delkoncept för höljets utformning, som därefter värderas och
testas. Det slutgiltiga konceptet som ska vidareutvecklas valdes ut gemensamt med
Donya Tech. Inför utveckling på systemnivå genomförs flera iterationer av höljet
för att fastställa den slutliga utformningen. Konceptet anpassas därefter utifrån
produktarkitekturen och de gränssnittslösningar som tas fram. Höljet anpassas sedan
för tillverkning med formsprutning, material bestäms och en analys för
designeffektivitet utförs. Simuleringar används för att utreda och verifiera
eventuella oklarheter som uppstår under processen.
Då produkten avses uppnå en CE-märkning ska en riskanalys genomförtras samt ett
utförligt användargränssnitt utvecklas, i enlighet med relevanta regelverk gällande
medicintekniska produkter i EU.
Arbetet resulterade i ett avtagbart hölje som uppfyller majoriteten av de identifierade
mätbara kraven. Höljet har ett välutvecklat användargränssnitt av två knappar och
en LED-lampa för feedback. Prototypen är optimerad inför den kommande
testperiod och ger en solid grund för vidareutveckling, så att en provtillverkning kan
utföras efter ytterligare revideringar gällande formsprutning-anpassning och
verifieringstester (Less)
Abstract
This master thesis project was carried out in close collaboration with Donya Tech
AB, who are developing a smart pregnancy band that monitors fetal movements.
The aim of the project is to develop a removable electronic housing that will be
integrated into the garment and protect its components.
The work has been based on Ulrich and Eppinger’s Product Development Process
in a combination with Rapid Prototyping, which enabled a structured yet flexible
development approach. Rapid Prototyping has been a crucial part of the process, as
the product’s other parts were developed in parallel by others at Donya Tech, which
required fast iterations and frequent feedback.
By collecting customer needs, benchmarking, external and internal... (More)
This master thesis project was carried out in close collaboration with Donya Tech

The aim of the project is to develop a removable electronic housing that will be

The work has been based on Ulrich and Eppinger’s Product Development Process
in a combination with Rapid Prototyping, which enabled a structured yet flexible
development approach. Rapid Prototyping has been a crucial part of the process, as
the product’s other parts were developed in parallel by others at Donya Tech, which
required fast iterations and frequent feedback.
By collecting customer needs, benchmarking, external and internal searching,
several sub-concepts for the design of the housing were generated, which were then
evaluated and tested. The final concept chosen for further development was selected
jointly with Donya Tech. Before system-level design, several iterations of the
housing were carried out to determine its final design. The concept was then altered
based on the product architecture and the interface design that was developed. The
housing design was altered for manufacturing by injection molding, materials were
selected and a design efficiency analysis was performed. Simulations were used to
investigate and verify the uncertainties that arose during the process.
As the product is intended to obtain a CE-marking, a risk analysis was conducted
and a detailed user interface was developed, in accordance with relevant regulations
for medical devices within the EU.
The project resulted in a removable housing that meets the majority of the identified
measurable requirements. The housing features a well-developed user interface
consisting of two buttons and an LED indicator for feedback. The prototype is
optimized for the upcoming test period and provides a solid foundation for further
development, enabling pilot production after additional revisions concerning
injection-molding adaptation and verification testing. (Less)
