Sitting with mobile devices In my major work I explore how people sit more hunched with a small screen in hand, despite the existence of ergonomic office chairs and other seating options. My question is if I can impact the user, and encourage them to obtain a better posture with the help of the armchairs rests, and in this way minimize the impact on the neck. As a designer I want to comment on, but also highlight our use of mobile devices by adapting the shape of the armchair to fit this need. / Ett sittande med mobila enheter I mitt examensarbete undersöker jag som designer hur människan sitter allt mer hopkrupet med en liten skärm i handen trots att det finns ergonomiska kontorsstolar och andra sittartefakter. Jag undrar om jag kan påverka användaren genom att hitta en ny form i karmstolens armstöd och på såsätt undvika eventuella låsningar och smärtor i nacke. Jag som designer vill kommentera, och även främja vårt användande av mobila enheter genom att förändra karmstolen så att armstöden passar vårt sittandet idag.

Följande rapport bygger på examensarbetet inom CAD-teknikerprogrammet påHögskolan i Halmstad. Arbetet innefattar framtagning av ett höjdjusterbartarmstöd till bilförare, en produkt som inte finns på marknaden idag.Utförandet av arbetet har bl.a. inneburit kriterieuppställning med krav ochönskemål, framtagning av produktförslag i form utav skisser och 3D-modeller, valav material genom undersökningar, även protoyptillverkning och produktanalyser.En del vikt har lagts på att genomföra marknadsundersökningar för att se om detfinns ett intresse för produkten. / The following report is based on the final thesis within the CAD-technicianprogram at Halmstad University. The work includes the development of a heightadjustable armrest for the driver, a product that’s not available on the market yet.The execution of the work has involved a criterion lineup with demands andrequirements, development of product proposals in the shape of sketches and 3Dmodels, choice of materials through studies, prototypes were produced for producttesting. Some attention has been given to carry out market research to see if thereis an interest in the product.

This report treats a product development project conducted in the course Degree Project for the Degree of Bachelor of Science in Innovation and Design Engineering, MSGC12, at Karlstads University. The course is a part of the faculty of heath, sciences and engineering. The report is written by the student Elin Berg, the supervisor of the project is Kristina Gullander and the examnier is Leo de Vin. The assignment is provided by Support Design, a Swedish company in Sunne that manufactures and distributes ergnomic chairs. The chairs are mainly sold to clients working in the dental and medical markets, but also office workers. Customers often sit on the chairs for long workdays, and several users sometimes perform precision work that requires relief for the arms and shoulders. Today, Support Design does not manufacture its own armrests but buys these from the US and China. The aim of the project is to develop an ergonomic armrest for dental operator chairs where the target group is dentists, dental hygienists and dentist assistants. The armrest should have functions that relieve, provide support and are flexible in order for the user to change the working position. The purpose of the project is to expand the Support Designs business by introducing its own armrest production. Eventually, this would give the company competitive advantages, facilitate logistics and result in better margins. The work process follows the methods that are part of a product development process. The phases of the project are project start, project planning, research, product specification, concept generation, concept selection, sub-report, design, final prototype, opposition, presentation, and exhibition. The research is the most important phase in identifying the user's needs, thus developing ergonomic armrests that fulfill the necessary functions.
