Based on the generative artificial intelligence painting model Stable Diffusion Application and Research in Product Appearance Design

Generative AI technology, mainly based on AIGC, has been developed at a fast-moving speed recently, among which Stable Diffusion uses diffusion models, possessing strong and surprising performance on image creation or processing. This paper aims to explain the essential functioning principles behind the Stable Diffusion model and show prospective uses within product appearance design. With Stable Diffusion, designers can quickly generate multiple design ideas, optimize product details, and improve design efficiency by applying painting models. Besides, Stable Diffusion still can accelerate the innovation ability of product design and the reaction speed to the market via rapid prototype generation and customized design based on user's requirements. At the same time, this paper analyzes some practical application cases, shows the practical effect of Stable Diffusion in product appearance design, and discusses the future development direction of the technology.
