AI Technical Summary

Technical Problem

Existing cardboard boxes are insufficient for cushioning and protection when transporting fragile items. Traditional methods increase weight or cost, and foam materials are prone to shifting during transportation, failing to effectively support the items.

Method used

Design a cushioning cardboard box, which uses an outer cardboard box and an inner cardboard box to form a ring-shaped buffer zone. It contains four sets of interlocking cushioning cardboard components and air columns. The rigid support of the X-shaped cardboard frame and the elastic cushioning of the air columns form a three-dimensional support structure.

Benefits of technology

It effectively resists side compression and corner drop impacts, improves the carton's resistance to deformation, and enhances cushioning and overall rigidity.
