Abstract: In order to increase the diversity and novelty of structural design in the structural innovation design of automated warehouse, the extension innovation method is applied to the structural design of shuttle shelf, and the general process of its structural extension design given. According to the user's demand and original data, the extension model of shuttle shelf is established, and the mapping relationship among function event element, component matter element and connection relation element is analyzed, and the implication system of function event element set is established. The relevant analysis network of automated warehouse shelf structure design is established, the analysis and implement the corresponding active transformation expanded, and then the creative strategy set of automated warehouse structure design obtained. The optimal strategy has been applied to enterprise production, with good practicability.
