With the global demand for reliable water management infrastructure, Xylem has identified the need for improved cable handling to prevent failures and extend the lifespan of their stormwater equipment. This thesis explores the development of an improved cable suspension system for Flygt column pumps, focusing on enhancing durability and reducing installation complexity through design and product development. The focus of the research is to improve the reliability and functionality of the cable suspension system while ensuring compatibility with existing column and pump system designs. The thesis captures the insights of industry professionals through interviews and benchmarking of other existing solutions on the market. A literature study is conducted to provide the theoretical framework for the product development of a new system. In addition, an observational study of a pump installation is carried out to gain real-life experience of installation conditions. An analysis of the current situation and system design provides the necessary information to generate ideas and formulate design requirements. The ideation phase involved a brainstorming session and a SCAMPER session aimed at generating new and diverse concepts for the cable suspension system. Initial ideas included implementing multimedia instructions through QR codes, changing the position of the cables, and improving the transportation routine. Several product development methods were employed, including the use of morphological charts. Combined User Journey Maps and storyboards were created to refine the ideas into whole-package concepts. The concepts were evaluated against the project specifications through Pugh matrix analysis and by conducting final interviews to verify the results and findings. Finally, the research questions are addressed. These include an examination of the existing cable suspension systems currently in use, an analysis of the installation process and an investigation into the reasons why some clients do not adhere to recommended practices. The study concludes with recommendations for the design of Xylem's Flygt column pumps future cable suspension system. The study proposes a new concept for the cable suspension system that improves ease of maintenance and reduces the risk of cable damage during installation and transportation. The concept includes the use of multi-media instructions, simpler components and safer installation. The recommendations also include suggestions for future research and potential improvements based on findings from the research, ideation, and development phases.
