Abstract [en]
At present, it has become increasingly common for the end user to vary their work position At present, it has become increasingly common for the end user to vary their work position during the working day. This is due to the fact that the worker is encountering repetitive activities for long periods of time, which can lead to various problems on the body. Variation and movement changes counteract positive fatigue and various problems that would hurt the body. From this a category of furniture that can be customized and changes after the user has grown forward and established itself in the furniture market. This candidate thesis takes place in the product development category and focuses on studying the economic and assembly consequences that may arise in connection with a design change. By studying the changes, it can be seen whether the changes will be economically justifiable, which is why the idea is to be implemented. The approach that the students chose to use was based on a preparatory study of the project, which then developed into concepts. These concepts were weighed against a product specification created at the preparatory study of the project. Once concrete evidence has been given that the requirements are met, a study on how the design can affect assembly and economy can be implemented. The goal of this project was to reduce the friction of the component by making a design change. A criteria that arose during the preliminary investigation is that the stability of the product shall not suffer when the friction is reduced and therefore a study was also made of stability after the design changes. The completed design change was then analyzed using observations, qualitative interviews, time studies, work measurements, analysis of flow charting, economic analysis and literature studies. The purpose of this analysis is to control changes that a structural change creates and to see what financial differences will occurring. By checking the assembly and the economic aspects of design changes, a profitable proposal will be reported to the company.
The proposal that is presented in the project means that the most suitable concept that is calculated and tested in practice, turned out to be better than the current plastic-detail. Comparing the current plastic-detail and the concept it turned out that the total time on the montage reduced 3.55 %, removes the lubricant from the mount process, capacity increase with 4%, maintain current stability in the table, total costs savings by 66.4% and theoretical friction reduction by 57.14%.
