ROLL UP! Produkten som förenklar hanteringenav en dragfjäder
Ett examensarbete som startade med en enkel idé och utvecklades till en prototyp
This report presents an independent thesis corresponding 15hp and was carried out on Högskolan in Halmstad during the spring of 2014. The thesis is the final course which ends a three-year mechanical engineering program with focus on technical design.The thesis started in an operation which electricians are exposed to every day. The operation in question is cable laying or wiring. The tool they use is called a tension spring and is a long and stiff wire, usually made out of nylon or fiberglass. The tension spring is fed through pipes in the walls and brings the desired cables with it on the way back. The problem shows up when the tension spring is drawn back by the electrician. The stiffness in the tension spring causes it to tangle itself and that causes unnecessary irritation and a waste of time. The problem gave an electrician and a good friend an idea about a product that could solve the problem in an easy and functional way.The idea started as a simple idea and with the help of several different product development methods from a production-, construction-, and design point of view a special methodology was developed, perfectly customized for the thesis. Potential customer gave the verdicts and helped create the needs and requirements for the product. The product went through a big process with creating different concepts and a lot of time was spent in CATIA for the final creation. One of the great goals of the thesis was to create a functional prototype, something that has been achieved and is now ready to be tested in a real environment.
