The work aims to study the innovative design method of corrugated cardboard display shelf and summarize the principles of structural design. Starting from multiple perspectives and working conditions, by means of design thinking, literature research, data analysis, sample production analysis and other methods, the study and summary of the innovative design of corrugated cardboard display shelf were conducted. By summing up the design principle of corrugated cardboard display shelf, B and C corrugated cardboards were suitable for small and medium-sized display shelves, and BE cardboard was suitable for large-sized display shelves; the load-bearing cardboards were oriented vertically to the ground; the minimum display height of the display shelf was approximately 40 cm, and the gold display height was 120 cm. The information and feelings passed to consumers should be morphologically taken into account. The insertion structure of corrugated cardboard display shelf could be in-line, plug-in and special-shaped. The sizes in the structure of corrugated cardboard display shelf should consider the folding size design, cardboard thickness and error. At the corners, a section of smooth protruding structure was designed with non-exposed cross-section and slotting at multiple polyline convergence, so as to improve the concentrated stress. Through the research on the structure of corrugated cardboard display shelf, some structural laws to follow are mastered. When the novel structure is pursued, its structural science and rationality are the focus of the design.
