Abstract
This master thesis investigates the possibilities of implementing magnets for several functions in a knob. The project was carried out in collaboration with Sigma Connectivity.

During a previous project at Sigma Connectivity, there occurred an interest in using mag-nets in a product called ”the knob”. This product is used to select options by swiveling an outer part or pushing buttons at the top. Exchanging some mechanics for magnets could possibly improve the product. It was interesting to see if magnets also could affect the feedback to the user.

The objective is to explore the possibilities of magnets in this type of product. Some benefits of magnets can be to avoid mechanical wear and to seal electronics due to contactless... (More)

If magnets are found to be useful, the results of this master thesis could act as a foundation for Sigma Connectivity to implement magnets in their future products.

Background research about magnets and sensors was conducted as well as findings of existing magnet solutions in order to achieve a greater understanding about magnets implemented in products. This acted as the foundation for the concept generation. Promising concepts were evaluated by using CAD and 3D-printing to create prototypes.

The final concept is a modified knob which utilizes magnets for several functions, both regarding the swivel function and the push top. Working prototypes with sensors demonstrates the functions.The results of this thesis is the final concept as well as recommendations for further development. (Less)
Abstract (Swedish)
Detta examensarbete undersöker möjligheterna att implementera magneter för flera funktioner i en så kallad ”knob”. Projektet utfördes i samarbete med Sigma Connectivity.

Under ett tidigare projekt på Sigma Connectivity uppstod ett intresse för att använda magneter i en av deras produkter. Denna produkt används för att välja alternativ genom att rotera en yttre part eller trycka på knappar på toppen. Genom att byta ut några av de mekaniska lösningarna till magneter kan produkten potentiellt blir förbättrad. Det är också intressant att undersöka om magneter kan påverka feedbacken till användaren.

Genom att byta ut några av de mekaniska lösningarna till magneter kan produkten potentiellt blir förbättrad. Det är också intressant att undersöka om magneter kan påverka feedbacken till användaren.

Syftet är att undersöka möjligheterna att implementera magneter i den här typen av produkt. Några fördelar med detta kan vara att reducera mekaniskt slitage och att innesluta elektronik genom kontaktlösa sensorer.

Bakgrundsforskning om magneter och sensorer samt att hitta existerande lösningar gav en större förståelse om hur magneter kan implementeras i en produkt. Detta användes som en grund för den kommande konceptgenereringen. Lovande koncept utvärderades genomCAD och 3D-printing för att skapa prototyper. Det slutgiltiga konceptet är en modifierad knob som använder magneter för flera funktioner, både rotationen och tryckknapparna.Fungerande prototyper med sensorer demonstrerar funktionerna.

Resultatet av detta examensarbete är det slutgiltiga konceptet samt rekommendationer för fortsatt utveckling. (Less)
