This paper aims to establish the functional requirement index system for intelligent baby stroller which provided theoretical basis and guidance for the design of smart baby stroller. Through the relevant literature research and market research methods, the functional demand index system of smart baby stroller is established by using kJ affinity graph method. Through the questionnaire survey, depth interviews and AHP analytic hierarchy process, the weight value of each functional index is calculated, and consistency inspection is completed. It is concluded that the functional requirement indexes of smart baby stroller of 1 target layer, 4 first level indexes and 17 second level indexes. The important order of the first level indexes is safety, comfort, convenience and internalization. The guardian have a high evaluation on the functions of intelligent brake assist system, prevent the baby from being carry away, speed regulation, intelligent assistance and real-time positioning and also hope have the function of intelligent sitting posture adjustment, intelligent sunshade, intelligent temperature control and automatic rocking chair. Finally, the research conclusion and design practice are combined to design a smart baby stroller.This design includes intelligent power, intelligent protection, intelligent recognition, intelligent security, intelligent voice and APP interface design.
