Abstract
This thesis presents a case study on the redesign of an electric percolator with
the aim of adapting it to a circular economy. The primary objective was to en-
hance the percolator’s design in accordance with a Slowing the Loop strategy,
focusing on longer product life and resistance toward obsolescence. A literature
study was performed to identify sets of Design for X (DfX) rules for this purpose,
resulting in five major areas of design: Design for Physical Durability/Reliability, Design for Emotional Durability, Design for Maintenance, Design for Modularity/Upgradeability and Design for Dematerialization.
Ideas were generated through structured brainstorming and concepts were
illustrated through renders in Creo Parametrics. One... (More)

Ideas were generated through structured brainstorming and concepts were
illustrated through renders in Creo Parametrics. One concept was developed to
be easily implemented and two concepts were developed for a more well devel-
oped circular product system. The realistic design case focused on an improved
handle design while the advanced concepts considered more drastic design over-
hauls. Two evaluation tools, CirCit Evaluation Tool and Circular Concept Eval-
uation Tool, were used to confirm the improvements.
The results concluded that the products improved in circularity, mostly in ar-
eas connected to maintenance, repairability and robustness. Improvements were
also made through the material selection, rendering the products more suitable
for recycling. There is a lot more work to be done concerning these concepts,
with testing and prototyping and further development and therefore, the main
takeaway from this project should be a first showcase of how circular product
design can look. (Less)
Popular Abstract
The transition to a circular economy has become very important for many companies, especially for Order Nordic AB. As home appliance brand owners, their ambition is to become pioneers in circularity which led to the collaboration with LTH and the writing of this thesis. The first steps in this transition involves the redesign of their C3 Percolator to investigate how home appliances can be altered to fit the circular economy.
