| Abstract | In design stage for automotive cable assembly, we face a problem when we solder thick wire and thin wire. There is a potential risk of the wire breaking in the soldering area and the breaking occurrence is high and uncontrollable. In order to meet the increasing need in the future, the more sophisticated automotive electronic product devices need this design to be applied to increase the safety, protection, comfort, and smooth operation of the car. This study uses the seven steps of McKinsey methodology to solve the problem. In the case of the companyˇ¦s automotive electronic wire manufacturing process, the bottleneck often encountered is that one side needs a thick wire riveting terminal to connect to the main wiring harness of the car body and the other side needs a thin wire riveting smaller terminals to save space. In this case, the company altered the wire structure to create a new style of wire structure. It successfully improved the grafting of thick and thin wires to avoid the potential risk of wire embrittlement caused by the welding process. Its success installed the designed product on the car to achieve the mass production plan. In terms of the verification parameters, the experiment is carried out according to the actual test conditions required by the car factory. The results obtained are sampled in large quantities by the Monte Carlo method and the sample population is randomly sampled to increase the number of samples to the set number. The data generated by it was verified. The result proved that the new style of wire structure not only avoid the potential risks derived from welding but the tensile test of the old style wire can withstand 1.988Kg and the tensile test of the new style wire can withstand 4.972Kg, the pulling force is increased by about 2.5 times. Moreover, the swing test of the old style wire can withstand 772.62 swings, and the swing test of the new style wire can withstand swings 8166.52 times, the swing is increased by 10 times. The results of this study can be used to prove that the new style of wire structure can achieve mass production and high stability. |
