Removable Cargo Container Base Brackets for Repairable Double-Plate Bases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo containers with double base constructions face challenges in repairing damaged brackets, as it often requires disassembly and removal of cargo, which is time-consuming, costly, and can compromise the integrity or temperature of sensitive cargo.
Innovation Solution
The introduction of replaceable brackets for cargo container bases, which can be accessed and replaced through a single plate, either the top or bottom plate, without the need to disassemble the container or remove the cargo. This design includes a bracket with a foot fixed to the bottom plate and a head secured to the top plate, allowing for easy replacement by removing fasteners from the bottom plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If brackets are secured to both top plate and bottom plate with rivets, then bracket strength and base stability are improved, but repair complexity and time increase due to requiring access to top surface
Solution Approach 1:
The patent extracts the fastening function from the top plate side and relocates it to the bottom plate side. The bracket head is now fastened only to the bottom plate through rivets, while the top plate connection is maintained through the bracket body structure. This allows repair personnel to access and replace brackets from the bottom plate side only, eliminating the need to access the top surface while maintaining the dual-plate attachment strength.
2Ease of repair
If cargo container requires unloading to access top plate for bracket repair, then complete bracket replacement is possible, but loss of time and potential cargo damage occur
Solution Approach 1:
The patent extracts the repair access requirement from the top plate and relocates it to the bottom plate. By providing fastener access through the bottom plate, the invention eliminates the need to unload cargo or access the top surface for bracket replacement. Repair personnel can service brackets while cargo remains loaded in the container, dramatically reducing repair time and avoiding cargo handling risks.
3Adaptability or versatility
If forklift tine enters base at angle, then forklift can accommodate uneven surfaces, but bracket damage occurs from impact
Solution Approach 1:
The patent repositions the bracket fastening points and structural elements to better withstand angled forklift tine impacts. The bracket head and body configuration, combined with the fastening system, is designed to absorb and distribute impact forces that occur when forklifts enter the base at angles, converting the previously harmful impact into a manageable load that the bracket structure can withstand without damage.

AI summary
A base for a cargo container including a bottom plate, a top plate, risers, and a bracket. The top plate has a top surface that faces away from the bottom plate. The risers interconnect the top plate and the bottom plate. The bracket extends between the top plate and the bottom plate and is configured to maintain a distance between the top plate and the bottom plate. The bracket is replaceable from the base without access to the top surface of the top plate.
