Produktutveckling av armstödsjusteringen på kontorsstol :
Sammanfattning: The report covers a bachelor’s degree project in mechanical engineering with a focus on product development and design at School of Engineering, Jönköping University. The thesis was carried on behalf of Flokk AB, which is a market-leading company that produces furniture for offices. The report includes the development of a concept proposal for the armrest height adjustment on the chair Activ in the RH line. The armrests in the RH line have adjustment options by height, width as well as the angle of the armrest stop. The company has stated that the RH line is being updated and currently two chairs in the line, Mereo and New Logic have gone through this update. In connection with this development, the company has decided that an update on the armrest for the chair named Activ should be done. The height adjustment of the current Activ armrest is the detail that visually stands out the most from the already updated armrests in the line. When developing the new Activ armrest, the height adjustment must provide the visual expression that has been applied to the remaining armrests in the RH line. Since Activ is classified as the economic chair in the line, the biggest challenge will be to provide the same type of adjustment technology, but in a more cost-effective design. Three issues were defined, and these formed the development process. Several specifications regarding requirements and the function were defined, these were involved in the development process. By early creating a picture of how competitors solve this function and studying how other adjustment functions worked, a foundation was created to generating several creative solutions. These evolved gradually during the process, using evaluations until a final concept was then created. The work focused on creating a cost-effective concept of the armrest height adjustment that follows the visual expression of the RH line. The focus is on creating the best construction for this function. The result was an armrest with a newly developed solution for the height adjustment for RH Activ.
