For end users of bottles with drinking water, the issue lies in the distrust of water quality when refilling bottles outside their home, and in cleaning reusable bottles due to limescale buildup, which affects the appearance of the bottle and creates a surface ideal for the formation of microorganisms (biofilm). This issue has led to the development of self-cleaning smart water bottles, where the cap plays the most important role. By using a UV-C LED diode, the cap destroys microorganisms in the water as well as on the walls of the bottle. The goal of the project is to develop a suitable cap casing based on input data, choose the appropriate cooling of the electronics, the manufacturing technology, and the materials, while also evaluating the robustness of the product using the finite element method. The later will focus on the strength and thermal analysis of the cap and its components, and identify potential points of failure in the product.
