As the design field continues to expand, the boundaries of design have become increasingly blurred. The design field appeals to a rising population of individuals who are not design professionals with a strong passion for design. These individuals are commonly known as non-designers. Non-designers could attempt to create designs based on universal design thinking models and methods. However, the efficiency and quality of design remain a challenge for them. With the rapid development of AI and the emergence of Generative Artificial Intelligence(GAI) tools, new opportunities have arisen for this group of people. The purpose of this study is to explore the supplementary role of Generative AI in interdisciplinary design projects, to enhance design quality and efficiency. The study employed a mixed-methods research approach, combining qualitative and quantitative methods. First, we conducted a persona to gather user requirements. Then, we created a user journey map to illustrate the user's pain points. Finally, we analyzed the existing popular GAI tools that can help with design. As a result, we proposed a product design strategic framework for design collaboration with GAI, and a GAI card toolkit that can be used for product design to assist non-designers in enhancing design efficiency and quality in interdisciplinary design projects. To validate the research results, we conducted user testing. The findings of this study will assist non-designers to better accomplish their designs more effectively and encourage more designers to use GAI as an important tool for creative work.
