Composite Panel Trailer Sidewall Logistics Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite panel sidewall constructions for cargo containers lack sufficient interior logistics slots for securing cargo, as the reduction or elimination of structural posts reduces potential securing locations, and traditional solutions can create snag points or protrusions that impede loading and unloading.
Innovation Solution
The introduction of recessed grooves in the composite panels to accommodate a vertically seated interior support with aligned slots, which are covered by an exterior support, providing additional logistics slots without creating snag points, while maintaining the structural integrity and thinness of the sidewalls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If structural posts are reduced or eliminated to reduce trailer weight, then trailer weight decreases, but the number of logistics slots for securing cargo decreases
Solution Approach 1:
The sidewall is segmented into multiple composite panels that can be joined together, with logistics slots integrated into the panel structure itself rather than requiring separate structural posts. This allows the sidewall to maintain cargo securing capabilities through panel-integrated slots while using lighter composite materials instead of heavy structural posts.
Solution Approach 2:
The composite panels are designed to serve multiple functions: providing structural support, enabling cargo securing through integrated logistics slots, and maintaining smooth interior surfaces. This multi-functionality eliminates the need for separate structural posts that would otherwise be required for cargo securing.
2Adaptability or versatility
If logistics slots are added to interior walls for cargo securing, then cargo securing options increase, but protrusions and snag points are created that impede loading and unloading
Solution Approach 1:
The logistics slots are nested within recesses in the composite panel structure, allowing the slots to be functional for cargo securing while remaining recessed and flush with the interior surface. This nesting approach prevents protrusions that would create snag points during loading and unloading operations.
Solution Approach 2:
The composite panels are designed with localized recesses at specific positions where logistics slots are needed, while the rest of the interior surface remains smooth and flush. This local modification provides cargo securing options without creating widespread protrusions that would impede loading operations.
3Volume of moving object
If sidewall thickness is reduced to maximize container capacity, then interior width increases, but structural integrity may be compromised
Solution Approach 1:
The sidewalls are constructed using composite materials consisting of a plastic core with aluminum or steel skins, providing high strength-to-weight ratio. This allows the sidewalls to be thin enough to maximize interior capacity while maintaining the structural integrity needed to support cargo and withstand loading operations.
Solution Approach 2:
The sidewall is divided into multiple composite panels that are joined together using splicer plates or posts at the edges. This segmentation allows each panel to be thin and lightweight while the joining system provides the necessary structural reinforcement at critical locations to maintain overall sidewall integrity.

AI summary
The improved composite panel trailer sidewall of the present invention provides a recessed groove or a pair of recessed grooves on the interior of the panel that are spaced apart from the edges of the panel. Slots are cut in the composite panel in the recessed groove or between the recessed grooves. An interior vertical support having logistics slots is seated in the recessed groove or grooves to provide additional locations to secure and divide cargo without creating snag points in the interior of the trailer.
