This report aims to describe the work of a bachelor thesis with a major in product development at Saab. The bachelor thesis is to improve one of Saabs existing products called MIT, short for “Moving Infantry Target”. MIT is used all around the world in harsh environment with high standards. MIT consists of one of Saabs other product SIT, short for “Stationary Infantry Target”, mounted on a trolley. SIT is a standard product of Saab but has to be modified before being mounted on MIT. The modification consists of the MDU, short for “Motor driving Unit”, and is a circuit board for controlling the electric engines located on the MIT trolley. The thesis aims to relocate the MDU from inside the SIT to the MIT trolley and still fulfill the requirements of the MIT. One important requirement is that all products need to have IP classification 67. IP classification is a standard measurement on how water and dust proof a product is.
To fulfill the requirements a protective box for MDU was developed. During the process there was some question in focus. Where should the box be located? Which manufacturing and materials should be used? How should the cable go inside the box and at the same time have IP classification 67? This was the basis for the work when developing the concepts. Two concepts were created in total. The first concept is about the location and how to attach MDU with the protective box. Next step concept is about how the lid will be attached and the cable lead-through.
A 3D model was created using the winning concepts and from that 3D model a prototype was created. The prototype was manufactured with a 3D printer.
