Cargo optimizing device for shipping containers and box trucks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shipping containers typically leave unused space above pallets unutilized, and existing solutions involve expensive, one-time use custom-built racks that are not reusable.
Innovation Solution
A collapsible, modular, and foldable cargo optimizing device with pivotable and retractable components that creates a second stacking level in shipping containers, allowing for efficient use of vertical space, featuring a central shaft, transverse and longitudinal support members, and adjustable rollers for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If custom-built racks are used to utilize vertical space, then storage capacity is improved, but cost and manufacturing complexity increase significantly
Solution Approach 1:
The rack system is divided into modular components including adjustable shelves, support legs, and connecting elements that can be independently manufactured and assembled. This segmentation allows for standardized mass production of individual parts, reducing overall manufacturing cost while maintaining storage capacity.
Solution Approach 2:
The rack design incorporates universal features such as adjustable shelf heights, standardized connection mechanisms, and configurable layouts that can accommodate various cargo types and container sizes. This multi-functionality eliminates the need for custom-built racks for different applications, reducing manufacturing costs through standardization.
2Quantity of substance
If custom-built racks are used to create second stacking level, then vertical space utilization is improved, but device complexity and installation time worsen
Solution Approach 1:
The rack system is divided into modular components including adjustable shelves, support legs, and connecting elements that can be independently manufactured and assembled. This segmentation allows for standardized mass production of individual parts, reducing overall manufacturing cost while maintaining storage capacity.
Solution Approach 2:
The rack incorporates adjustable and reconfigurable elements such as movable shelves, telescopic legs, and flexible connecting mechanisms that allow the structure to adapt to different cargo configurations. This dynamic design simplifies installation and reconfiguration compared to fixed complex structures.
3Ease of operation
If traditional single-level loading is used, then loading simplicity is maintained, but storage capacity is reduced due to unused vertical space
Solution Approach 1:
The invention transitions from traditional single-level horizontal loading to a multi-level vertical loading system. By adding vertical dimension with adjustable shelves and support structures, the system充分利用 three-dimensional space while maintaining operational simplicity through standardized access points and modular components.

AI summary
A cargo optimizing device includes a first and a second cargo platform pivotably attached to a center shaft. The first and second cargo platforms have transverse and longitudinal support members. When unfolded into a cargo support configuration, the device forms a planar cargo support. The device has a two-part platform frame in which the members are suspended and can be folded around the central shaft for storage. Support legs are pivotably attached to the frame and retractable rollers extend from the periphery. The device is modular: the transverse members slide to bridge to a second device. The frame and the attached longitudinal members have apertures aligned to accommodate the sliding transverse members. The cargo optimizing device forms a second stacking level in a shipping container which otherwise has an upper level of unused space. The device can be supported by legs or suspended by belts.
