Ergonomiskt knapp- och dragkedjehjälpmedel

Abstract [sv]

Detta projekt syftade till att förbättra ett hjälpmedel för att knäppa knappar och dra upp dragkedjor för personer med reumatiska sjukdomar, greppsvårigheter eller smärta och nedsatt rörlighet i fingrar och handleder. Befintliga produkter på marknaden upplevs ofta som svåra att använda, otillräckligt ergonomiska och exkluderar många inom målgruppen.

Genom en användarcentrerad designprocess genomfördes förstudie, kravspecificering, konceptgenerering och utvärdering. Tre koncept togs fram, varav ett med vinklat handtag valdes vidare för utveckling då det underlättar rörelser med hela armen snarare än enbart handleden. Detaljkonstruktion, prototyptillverkning och användartester genomfördes, där det nya hjälpmedlet bedömdes mer bekvämt, intuitivt och visuellt tilltalande än ett kommersiellt alternativ.

Projektet visar att även enkla ergonomiska förbättringar kan öka användbarheten och självständigheten. Arbetet utgör ett första steg mot en mer tillgänglig, värdig och funktionell design av vardagshjälpmedel.

Abstract [en]

This project aimed to improve an assistive device for buttoning and zipping, designed for individuals with rheumatic diseases, grip difficulties, or pain and reduced mobility in fingers and wrists. Existing products on the market are often perceived as difficult to use, insufficiently ergonomic and exclude many within the target group.

Through a user-centered design process, a preliminary study, requirement specification, concept generation and evaluation were conducted. Three concepts were developed, one of which, with an angled handle, was selected for further development, as it facilitates movement using the entire arm rather than just the wrist. Detailed design, prototype manufacturing and user testing were carried out. The new assistive device was rated as more comfortable, intuitive and visually appealing than a commercial alternative.

This project shows that even simple ergonomic improvements can increase usability and independence. The work represents an initial step toward a more accessible, dignified and functional design of everyday assistive products.
