Abstract [en]

This report presents a thesis project conducted by two students at Mälardalens högskola. The project covers 15 points in industrial design and was conducted during April to June 2014. The principal of the thesis works at Plastic Produkter. The assignment was to develop equipment for an effective way to dose, mix silicon, fill a special designed plastic bag and then seal it. The bag is then formed into a breast model.When a customer for various reasons decides to do a breast augmentation or a breast reconstruction, there may be doubt or uncertainty about the result. The idea of this product is to show the client and the client’s environment how the result of a future breast surgery would look like.The process began with a specification of demands and a functional analysis to define the issue. Once the problem was defined a competitor analysis was made to get an idea of how the competitors solve similar problems. The authors concluded that there were no obvious competitors, but there were products with similar purpose.The authors chose to start focus on how the mechanism would work. A partition of the machine made that a generation of ideas could be made on each separate part and then they could be combined into several concepts. A Pugh’s matrix and a QFD were made on the concepts for the mechanism to decide which concepts that should be developed. The winning mechanism concept was then combined with the remaining concepts parts that were selected. The final concept was a machine that is simple and easy to use, which meets the specified requirements.Tests and calculations were made to support the decisions that were taken. When the final concept was fully developed and tested, a casing was created which was formed after the inside of the machine. The casing is designed to fit into the customer environment and is developed for a first production. A 3D sketch of the final concept was made in SolidWorks to easily get a visual image of the concept. The entire machine and its components are presented in the results. Concept care was made on the machine to get low production costs and to make it easy to assembly. To locate and eliminate any future risks, a failure modes and effects analysis called FMEA was made. To easily evaluate the dynamic of the team and the process of the project, the team used an evaluation tool called PIPS. This gave an overall look of that the group assignment worked well throughout the process. Even if the project was in industrial design, it was a lot of construction that was needed to process. This meant that the project took a different and better direction than expected and gave the authors a greater overview of how the machine would work. The authors believe that the goals of the thesis were achieved well in this project.
