Detection system for bacteria in drinking water: Development of support systems for real-time bacteria analysis

Abstract

This project covers a product development process for the support systems of a water analysis method for drinking water which can be used to automize the moni toring process of bacteria or to manually test the water and get faster results than current methods. The project includes several stages: Research, concept generation, Concept selec tion, concept development, concept verification, and recommendations. The research stage includes all the information gathering including patent analysis, competitor analysis, interviews, and a law analysis. The concept generation stage includes a brainstorming session and a morphological matrix. The concept selection stage in cludes an elimination matrix, pugh-matrixes, and a focus group in order to select the final concept. Concept development stage consists of a CAD model creation and a 3D-printed model. A concept verification stage consisting of tests in order to verify the level of readiness according to the requirement specifications. And the final part of the report is a presentation of the information collected during the project and some recommendations for further work on the project. The project was executed at a start-up company called Nocoli and the aim of the project is to support Nocoli in the development of a new era for water analysis systems. The project goal was to create a supporting system for a new technol ogy created by a scientist at Halmstad University, the technology for water analysis worked in a lab environment and needed a product development process in order to test the functionality outside of the lab and to show potential customers and in vestors. The plan for the supporting systems was to move water through the model in a controlled manner through a microchannel. The project ends with a prototype that visualizes the supporting systems and shows proof of concept in transporting water through the product for the analysis to work with the help of both pumps and valves.
