Abstract: This article investigates the impact of automotive product design on the manufacturing cost of automobile assembly, identifies the key factors that affect assembly cost at the design end, and analyzes and studies five major aspects through case comparison methods: integrated design, convenient installation structure design, reduction of installation points, optimization of fasteners, and optimization of adjustment structures. A set of methods for controlling assembly costs from the product design end is obtained. The research shows that product design has a decisive impact on the efficiency improvement and cost reduction of the subsequent assembly process. This study not only provides practical manufacturing cost reduction solutions for automobile manufacturers, but also provides new ideas for cost management and cost optimization of the entire industry
