Generative artificial intelligence technology is becoming a trend in the field of design. An increasing number of designers and scholars are using AIGC technology to enhance design efficiency and creativity during the design process. This study compares the traditional brand logo design process with the AIGC-assisted brand logo design process, proposes a brand logo design framework that utilizes AIGC text and image tools, and validates the effectiveness of the framework through the actual case. The framework helps designers to create and make decisions more efficiently at various stages of brand logo design, shortens the design cycle, and at the same time enhances the quality and creativity level of the design works.
