This study explores the integration of game methodologies into product design to foster innovative thinking and enhance the design process. While mainstream design thinking and product design methodologies primarily emphasize market orientation, the application of game mechanics in design innovation remains relatively underexplored. Grounded in game mechanisms and logic, this research examines their theoretical feasibility and evaluates their effectiveness in stimulating creative thinking through practical design applications. By offering a novel perspective on design methodology, this study provides designers and scholars with an alternative approach to unlocking creative potential in product design.
