Kostnadseffektiv design och framtagning av flexibel innerförpackning åt elektronikprodukter / Cost efficient design and development of flexible packaging interior for electronics

Berglund, Sofie January 2013 (has links)
Abilia utvecklar, tillverkar och säljer tekniska hjälpmedel till personer som antingen har en fysisk eller psykisk begränsning som påverkar deras vardag. För att dra ner på kostnaderna och få en bättre enhetlighet vill Abilia att ytterförpackningarna ska standardiseras samt att ett flexibelt inrede som ska kunna anpassas till många av företagets produkter utvecklas. En förstudie lade grunden för projektet där många olika områden och metoder undersöktes. De existerade förpackningarna utvärderades, deras och produkternas livscykel kartlades varpå det framgick vilka som var projektets huvudanvändare. Dessa intervjuades och en kravspecifikation kunde sedan fastställas. Förstudien resulterade i att det fanns två grupper av produkter som lösningen måste kunna anpassas till. Lösningen måste även vara flexibel både för produkterna och för dess tillbehör. Hjälpmedelscentralerna som visade sig vara projektets huvudanvändare hade krav att lösningen skulle vara hållbar och ge förpackningen en strukturerad insida. Koncept genererades med hjälp av en praktisk idégenerering som resulterade i olika former och konstruktioner. Konceptval genomfördes genom diskussion med personal från Abilia samt genom en viktad konceptvalsmatris. Projektet resulterade i ett flexibelt och hållbart inrede i två lösningar. En produktpresentationsdel som har en konstruktion med nedvikbara flikar som gör det möjligt att kila fast produkter oberoende av storlek samt en flexibel tillbehörsdel som både kan regleras i höjdled och sidled. Lösningen uppfyller kraven från kravspecifikationen och har verifierats av experter inom området att den fungerar i verkliga situationer. Materialet i lösningen är det bäst anpassade för funktionen och är även det material som har lägst miljöpåverkan av de som undersöktes i projektet. / Abilia develops, manufactures and sells aids for people who have either a physical or mental limitations that affect their everyday lives. In order to save money and get a better uniformity Abilia want to standardize the packaging and develop a flexible interior that can be adapted to many of the company’s products. A pilot study laid the foundation for the project where many different areas and methods were examined. The existing packages were evaluated, and their and the products lifecycles were identified and that made it clear who the projects user was. They were interviewed and a product specification could be established. The pilot study resulted that it was two groups of products and the solution must be able to adapt to both. The solution must also be flexible to the products and their accessories. The Hjälpmedelscentralerna turned out to be the users in this project and they had requirements that the solution must be sustainable and provide a more structured inside of the packaging. Concepts were generated with a practical idea generation that resulted in different forms and constructions. The concept selection was made after discussion with the staff from Abilia and through a balanced concept selection matrix. The project resulted in a flexible and durable interior in two parts. A product presentation part which has a design with folddown flaps that allows the product to get stuck no matter which size and a flexible accessory which can be adjusted both vertically and horizontally. The solution fulfills the requirements from the product specification and has been verified by expert that it would work in real situation. The material in the solution is the best suited for the function and it is also the material with the lowest environmental impact of those surveyed in the project.

Modular Locking System to RBS Cabinet

Almqvist, Josefin, Sundelius, Emma January 2013 (has links)
Radio base stations contain equipment which enables the use of cell phones all around the world. ERICSSON is developing these stations and everything connected to the area, such as electronics, software and hardware. In a new project ERICSSON plans to make their hardware modular, to satisfy all their customers around the world even if their preferences differ. The task that was given to us was to develop a modular locking system to the radio base station cabinets.The concept was developed in an integrated working process that focused on a user centered final product. The process included the definition of the problem, preliminary studies of areas which are connected to the problem and a summary of the demands that the customers mediated in a list of requirements. The idea generation generated lots of ideas that later on were developed into different concepts. The concepts were evaluated before the final decision was made together with ERICSSON.The final product is a lifting handle connected to a rod and latch system, which already existed. A new mechanical function was created to make the new handle function with the old system. The locking system is modular and it is possible to choose which way to lock the handle, with a cylinder lock or a padlock. Only one module, the cylinder in the middle, needs to be switched to get the other solution. The other parts are the same; this makes the product modular. The lift handle is an entire new design, developed in the project.
