The design aims to improve the competitiveness of the enterprise by extracting effective user value, establishing a product service system, satisfying the user's needs, and analysing the method of extracting the shape. In this paper, the researcher first selects the target user, draws the user journey map, analyses the user's psychological activities, and uses the innovative design thinking to extract the user value. Secondly, according to the positive value element, the 'human-object' three-dimensional ecological circle is created, at the same time, using AHP hierarchical analysis software to analyse product modelling and build the product service model. Finally, the reliability of the model construction method was verified by the intelligent air quality monitor product service system, and the requirements to meet the needs of users were met. At the same time, it can also provide certain reference for other product service design, reflecting the market competitive advantage of the product.
