Handburen dykdator : Konstruktion av en produkt som tillåter användning av en mobiltelefon som dykdator

Sammanfattning: This report describes a bachelor thesis whose main task has been to develop a concept for a new product that allows the use of a mobile phone as a dive computer. This is relevant because it will help dive centers to attract new divers and increase their enthusiasm by making the sport easier and more social. A concept study has been initiated with the initial phases of Liedholm's established product development methodology but with its own interpretation of the concept development and resulted in a final concept of the product. This concept has been developed and designed to be ergonomic with the help of a market research. The remaining design has been made with respect to manufacturing, strength calculations and innovative ideas originating in existing products. This work has resulted in a fully developed and dimensioned concept with associated design documentation in the form of both 3D models and drawings. The result was checked against a list of design criteria that was developed for the entire product development process at the beginning of the work and met 19 of the 31 points. A 3D printed prototype containing the four main elements has also been delivered that gave a positive feel of future use. The work is considered to have given good results which are useful in further design. Since work only deals with a small part of the overall product development, some design and production work remains before a finished product can be launched on the market. This includes, among other things, detailed calculations regarding sealing and buoyancy, a attachment device for comfortable and safe use, production characteristics and a thorough market research.
