The project aims to improve the design for the assembly and fabrication of a cell module in a robotic cell. This report presents a structured design process covering the approach, methods, results and conclusions. Problems related to the geometrical complexity of the module are addressed and key objectives for the improvement of the assembly and fabrication are established. Secondly, an investigation of the product and relevant aspects in the current market is carried out. Next, the architecture, functions and requirements to be fulfilled by the battery module are developed. The list of requirements is key and essential as it serves as a guideline for the following phases. During the concept generation stage, a brainstorming process is used to sketch out ideas, followed by an evaluation of the final concept using the information from the interviews, a checklist of the guidance table and the spider diagram. This process allows to identify which concept can best meet the proposed objectives. Furthermore, the final result is presented through renderings and modelling for a complete visualisation. Finally, the report includes conclusions highlighting the positive and negative aspects of the project, as well as areas for improvement and achievements.
