Collapsible Cargo Container With Integrated Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cargo containers are inefficient in space usage when empty, as they occupy valuable space during transport, and existing collapsible designs are cumbersome and prone to damage or loss due to removable parts, and the corrugated construction makes loading and unloading difficult.
Innovation Solution
A collapsible cargo container design that secures ends to the ceiling, allowing side walls to collapse onto the floor, maintaining the same footprint, and using a specialized spreader for handling and folding, with a composite construction featuring smooth inner and outer panels to prevent interference with forklifts and improve loading/unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If containers are made collapsible to reduce space when empty, then space occupancy is reduced, but structural complexity and risk of damage increase
Solution Approach 1:
The container is divided into collapsible side walls and rigid end walls, allowing selective folding of only the side walls while maintaining structural integrity at the ends. This segmentation enables space reduction without compromising overall structural strength.
Solution Approach 2:
The collapsible side walls are designed to fold inward and nest against the rigid end walls, creating a compact configuration where the side walls are contained within the volume defined by the end walls, significantly reducing the overall container volume when empty.
2Adaptability or versatility
If removable parts are used in collapsible containers to enable folding, then collapsibility is achieved, but parts are subject to being misplaced, lost, damaged and/or stolen
Solution Approach 1:
The hinge assemblies are permanently integrated into the side wall structure, merging the folding mechanism with the wall itself. This eliminates separate removable parts while maintaining the collapsible function, as the hinges remain fixed to the container structure.
Solution Approach 2:
The container structure itself provides the folding mechanism through permanently attached hinge assemblies that enable collapse without requiring external removable components. The structure serves its own folding need through integrated design.
3Strength
If corrugated construction is used in containers, then structural strength is improved, but loading and unloading becomes difficult
Solution Approach 1:
The container employs different surface qualities in different locations: corrugated construction is used specifically for the side walls where structural strength is most needed, while the end walls and interior surfaces are smooth to facilitate easy loading and unloading operations. This localized application optimizes both strength and ease of operation.

AI summary
A collapsible cargo container is disclosed wherein end walls are pivoted into the container when empty and locked against the roof, and then side walls buckle via hinges into a folded configuration. The folded configuration is achieved easily with a modified spreader without the need to otherwise disassemble or deconstruct the container, leaving no loose parts or tools. The cargo container preferably constructed with an improved light weight panel that facilitates loading of the container while improving strength and reducing weight.
