The work aims to reduce the empty container storage and repositioning cost of port and shipping enterprises, improve the supply chain efficiency of the global container shipping market and increase the container turnover. A ''lose weight'' method of empty container storage and repositioning cost, namely a new fully folding container and its auxiliary tools, was proposed and designed. Based on the references and innovative achievements in relevant field, as well as ''Series 1 Freight Containers-Specification and Testing'', the planar graph and 3D diagram of this folding container and its auxiliary tools were designed through Adobe Illustrator and SolidWorks. With the help of Workbench, the simulation test of the folding container was conducted to study its strength and rigidity under the maximum stress and deformation. Result showed that the maximum stress of 131.75 MPa and the maximum deformation of 4.1255 mm of the folding container were within the allowable range of ISO 1496—1. At the same time, the volume of the empty container in the folded state was only one-third of that of the ordinary empty container, which was suitable for wharf yard, container freight station, cargo warehouse and container liner. This invention is helpful to reduce the storage cost of empty containers for port enterprises, decrease the repositioning cost of empty containers for liner shipping firms, and provide sufficient container source for shippers to transport cargoes. It has high value of application.
