This thesis presents developing work about air leakage detecting method for Volvo car body. The purpose of this project is to find out an efficient and effective way of detecting the air leakage point in car body that meets all the requirements given from Volvo Car Corporation. The whole project contains investigation work about air leakage detecting methods existed in all industries nowadays and a complete air leakage detecting system was developed based on the current requirements the company provided. To achieve the goals, the group firstly conducted deep investigation of the problem, including find out the root of the problem and the effect of the problem. Meanwhile, requirements and desires from the company were gathered, analysed and translated into requirement specifications in order to fully understand the purpose of the project. Based on the preparation work, the group carried a thorough market research regarding air leakage detecting methods which are applied in other competitiveness automobile companies and industries. Later on, a set of evaluating system were applied to scientifically estimate each methods found. Depended on the methods evaluation result, the group decided to proceed with methods that involve in devices-aided. During the concept development phase, different concepts were generated based on the benchmarking result or combined from each other and later on being eliminated according to systematic evaluation procedures, which involved in Weight Decision Matrix and Kesselring Matrix. It is worth mentioning that the concept development phase is a circulation between concept generation and concept elimination, i.e. new concepts were generated from last elimination and passed to next elimination with old remaining concepts. At last, three different concepts fit in three different testing circumstances were raised and explained in detail. Along with the conclusion of the development results, the group also provided the company with cost estimation for each concepts.
