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.

Le cancer du sein, l'une des principales causes de mortalité féminine dans le monde, peut être traité avec plus d’efficacité s'il est détecté à un stade précoce. L'imagerie micro-ondes (MWI), technique émergente, apparait comme prometteuse pour compléter les méthodes de diagnostics actuelles. Elle est non-ionisante et potentiellement peu coûteuse, possédant ainsi des caractéristiques clés pour être un bon candidat pour la détection de masse et pour un dépistage fréquent. Cette thèse résume les résultats d'une recherche novatrice menée sur un système micro-onde visant au dépistage dans les tissus mammaires. Une première technique de détection fréquentielle directe est proposée en utilisant une antenne compacte HFA mise en cavité spécifiquement conçue pour une utilisation en contact direct avec le sein. Les résultats de simulations sont analysés et comparés à des mesures faites au CHRU à Brest, ce qui a permis de valider un modèle fantôme dispersif du sein mais aussi de mettre en évidence les limites de cette 1ère technique. Une 2ème approche ULB est proposée dans laquelle une étude de la distribution du champ électrique à l’intérieur du modèle est menée pour deux types d’antennes ULB dédiée à une utilisation en contact direct de la peau, un monopole et une Vivaldi directive, toutes deux insérées dans une cavité. Cette étude comparative a mis en évidence l'intérêt d’utiliser une antenne directive pour cette application. Finalement, une étude élaborée dans le domaine temporel est menée en utilisant deux configurations d’antennes, une configuration mono-statique et une autre bi-statique afin d’étudier la possibilité de la détection tumorale et de la reconstruction d’image. Cette étude permet de justifier la mise au point d’un système antennaire dont l’objectif est de focaliser le maximum d’énergie dans le sein, notamment en concevant les antennes pour une utilisation en contact direct avec la peau pour augmenter la probabilité de la détection des tumeurs cancéreuses. / Breast cancer, one of the primary causes of women mortality worldwide, can be effectively treated if detected at its early stage. Microwave Imaging (MWI), an emerging technique, promises to complement the currently used diagnostic modalities.It is safe, non-ionizing and potentially inexpensive, thus possessing key features to make it a good candidate for frequent and mass screenings.This thesis summarizes the results of an innovative research conducted on a microwave system for breast tissue screening.A first direct frequency detection technique is proposed using a compact HFA antenna inside cavity specifically designed for use in direct contact with the breast. The simulations results are analyzed and compared to measurements made at CHRU of Brest, which validated a dispersive breast phantom model and demonstrated the limits of this first technique.A second UWB approach is proposed in which a study of the electric field distribution inside the model is conducted for two types of UWB antennas dedicated to use in direct skin contact, a monopole and a directive Vivaldi, all two inserted into a cavity.This comparative study has highlighted the interest of using a directional antenna for this application.Finally, the thesis focuses on time domain study using two configurations of antennas, a single-static configuration and another bi-static to study the possibility of tumor detection and image reconstruction and justifying the development of an antenna system whose objective is to focus the maximum energy in the breast to increase the probability of detection.
