Golden Ratio : Utformning av en ny filterbryggare

Sammanfattning: During Spring semester 2011, Linda Engstrom and Malin Heder performed “Golden Ratio”, a thesis which included 22.5 hp. The thesis followed the syllabus for the Degree Project for degree of Bachelor of Science in Innovation and Design Engineering (MSGC12) which was a unit in the Innovation and Design Engineering program within the Faculty of Technology and Science at Karlstad University. The client was Crem International AB, a company located in Åmotfors that develops the design, manufactures and markets coffee machines. The supervisor at the company has been Peter Larsson and supervisor at Karlstad University has been Monica Jakobsson. Examiner for the thesis has been Professor Fredrik Thuvander at the Faculty of Technology and Science at Karlstad University. Crem International AB controls a patent, representing a new technology to streamline and minimize use of energy during the coffee preparation and results in a good coffee quality. The company intends to integrate this technology in a filter coffee maker and a desire for a new design that differs from the traditional form of a filter maker. This specific request was the starting point of this project. When the mission was handed to the group, the filter coffee maker merely existed as a vision termed “Golden Ratio”. The project was highly focused to find as essential material as possible. This was important in terms of developing a form that reflects the needs of the users and the requests and demands on the market. The phase of research during the project has, due to the needs and demands, consisted a thorough market research containing several interviews, observations and analysis by professionals, experts in the coffee segment and coffee machine manufacturers. Through several methods of generating ideas and using Focus groups and individual reflections, the group generated six innovative concepts of a future filter coffee maker. Based on these six concepts the group used three alternative evaluation methods to select the most appropriate solution, this in consultation with the supervisor at the company. The final selection of the concept was a combination of several concepts. The choosen concept was a flexible and sober solution that could be adapted depending the capacity of the environment. The chosen concept consisted of a preparation machine and a tap with an integrated vessel for the brewed coffee. During the concept development the selected concept was visualized by CAD-modelling, a presentationmodel and graphic illustrations. The selected concept included a proposal for the design of a future filter coffee maker and a suggestion of the materials and colors. The developed supplementary list for the concept also showed the group more opportunities for further development.
