LOMAH in a Box : Produktutvecklingsprocess

Sammanfattning: This report presents a bachelor thesis in Mechanical Engineering, Product development and design and has been carried out in collaboration with SAAB Training & Simulation in Huskvarna. The thesis project involved a product development process beginning with establishment of specifications and concept generation through 3D modelling which then resulted in a complete prototype. The task presented by SAAB Training & Simulation consisted of developing a portable combined target holder and transportation case for their current livescoring projectile monitoring system, the LOMAH 700. A theoretical background was necessary to gain an understanding of the complex nature of a product development process and the stages involved. Different concept generation and evaluation methods were explored, including the Go/No-go and Vendor Evaluation Matrices, as well as engineering practices such as Design for Manufacturing and Design for Assembly. Various materials and production techniques were also investigated to optimize functionality of the product, as well as cost of production. The methods researched in the theoretical background were then applied throughout the development process. Brainstorming was used to generate numerous different ideas which were then evaluated using three different matrices. This resulted in one leading concept which was further developed through detail work and review. The work continued with 3D-modelling and drawing using SolidWorks to ultimately produce the grounds for manufacturing. The final concept consisted of a transportation case ordered from the case manufacturing company, SKB Cases. Custom-made components included legs with adjustable length and angle and a target holder used for fixing a target and the LOMAH 700 onto the transportation case. The custom-made parts were produced by SAAB, and the prototype was then assembled. The prototype was ultimately tested to ensure the fulfillment of the specifications defined by SAAB Training & Simulation.
