Digital cultural and creative products have transformed the landscape of cultural dissemination; however, their emotional resonance remains insufficiently examined. Although such products fulfil functional demands, contemporary consumers increasingly seek designs that align with their emotional and spiritual expectations. This study investigates the incorporation of emotional design into digital cultural products, augmented by artificial intelligence (AI), to evaluate its influence on consumer purchase intention. It addresses a notable gap concerning the application of emotional design principles within the realm of digital cultural products. Adopting a mixed-method research design that integrates both qualitative and quantitative approaches, the study utilises parametric design, intelligent hardware, and 3D printing technologies to embed emotional design elements into these products. Through an experimental framework, 20 participants assessed emotionally designed products against traditional ones, evaluating them based on five dimensions: appearance, functionality, cultural significance, creativity, and purchase intention. The results reveal an 8.23% increase in purchase intention for emotionally designed products compared to traditional alternatives. Furthermore, participants assigned higher ratings to emotionally designed products in appearance, creativity, and cultural value, with scores generally exceeding those of traditional products by 1 to 2 points. These findings underscore the capacity of emotional design to strengthen consumer engagement and enhance purchase intention. The study highlights the critical role of emotional design in shaping digital cultural products and suggests that its thoughtful integration may foster greater consumer satisfaction, loyalty, and sales.
