This thesis aims to enhance the light ramp of Rottne Industri AB's harvester. To achieve this, various theories and methodologies were applied throughout the project. By employing a systematic product development process, the authors were able to minimize manufacturing costs while incorporating additional features for improved functionality. The newly developed design resulted in several significant improvements. The height of the light ramp was reduced by 15%, which not only aligns with the project’s goals but also contributes to better integration with the machine's overall structure. The manufacturing costs have been lowered, making the production process more economical and efficient. Furthermore, the lighting coverage has been enhanced to provide better illumination of the nearby area that is surrounding the harvester, thereby increasing visibility and safety for the operator. Overall, the project successfully met all the set objectives, delivering a more efficient, cost-effective, and functional light ramp design for Rottne Industri AB’s harvester.
