At present, the design and development of cultural and creative products in China is the result of multiple factors. The cultural attributes and characteristics of cultural and creative products determine the inevitability of emotional factors. In order to seek better emotional and design experience, "uncertainty factors" are involved in cultural and creative product development to perfect and gain the value of cultural and creative products. The work aims to adopt the unique design factors and ideas of "uncertainty" in the development of cultural and creative products, in order to provide a more reasonable, scientific, effective and open research and development approach for cultural and creative product design. Based on the concept of user experience research, a combination of "uncertainty factors" intervention research and result oriented dialectics was adopted. By analyzing the intervention principles and design methods of emotional factors in the design process, the emotional value of "uncertainty factors" in cultural and creative design was addressed, and more rational user needs were sought through the utilization of these factors. A design method for cultural and creative development is studied by utilizing "uncertainty factors" in cultural and creative design. A systematic and dialectical analysis is conducted on the utilization of design front-end, design process, and design terminal. A research on the interdependence between emotional factors and the development of cultural and creative products is constructed and a complete, interesting, reasonable and effective promotion path in the development of cultural and creative products is extracted.
