Abstract In the product conceptual design process, clearing design task and using the digital twin technology can better handle a large number of user data, monitor function operation, analyze target products, and promote the generation of design solutions. Firstly, the design task was taken as the entry point, user factors were introduced, task analysis method and scenario decomposition method were integrated to decompose the design task, and task flow models in the task domain was constructed. Secondly, the fuzzy comprehensive evaluation method was used to quantify the design task, clarify the design task, further decompose the design task, and the physical domain entity task scenario model was constructed. Based on the trend of task flow, interactive channels and virtual domain data types were analyzed to build the virtual domain task scenario model and complete the construction of digital twin model based on design task. Based on the direction of task flow, interactive channels and virtual domain data types were analyzed to build the virtual domain task scenario model and complete the construction of digital twin model based on design task. Finally, this method was applied to the construction of digital twinning model of intelligent classification trash can, which expanded the application of digital twinning in conceptual design. The design quality of product can be improved by integrating user factors into the design task during the conceptual design stage of products.
