Load Beam Assembly With Side Ribs For Cargo Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load beam assemblies in storage units, such as those in commercial vehicles, often fail to provide adequate horizontal support for cargo, leading to potential sliding during transport and damage due to insufficient contact area and sharp edges.
Innovation Solution
An elongate beam assembly with a top wall and side surfaces that extend between the bottom and top walls, featuring a textured surface and ribs for enhanced friction and a box-like structure to distribute force over a larger area, minimizing sliding and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional load beam assemblies are used, then the structure is simple, but the contact area with cargo is insufficient and edges are sharp causing damage
Solution Approach 1:
The beam assembly incorporates side surfaces that extend downward from the top wall to create localized contact areas with the cargo. These side surfaces are positioned at specific locations along the beam to maximize contact with cargo sides, preventing sliding without requiring complete redesign of the entire beam structure.
Solution Approach 2:
The invention transitions from a traditional single-surface top contact beam to a multi-dimensional contact structure by adding vertical side surfaces. This creates contact in both horizontal and vertical dimensions, forming a box-like engagement with cargo that prevents sliding while maintaining structural simplicity.
2Strength
If load beams provide vertical support, then cargo can be supported between floor and roof, but horizontal support is inadequate preventing cargo stability
Solution Approach 1:
The side surfaces are strategically positioned to contact specific portions of cargo sides, providing localized horizontal support where needed most. This targeted approach enhances cargo stability without requiring additional horizontal support structures.
Solution Approach 2:
The beam assembly combines vertical support function of the top wall with horizontal support function of the side surfaces, creating a composite support system that addresses both vertical strength and horizontal stability requirements simultaneously.
3Ease of manufacture
If beam contact area with cargo is minimized, then manufacturing is easier, but friction is insufficient allowing cargo sliding during transport
Solution Approach 1:
The side surfaces extend vertically downward from the top wall, adding a vertical dimension to the contact area. This increases the total surface area in contact with cargo without complicating the horizontal footprint or requiring additional beams.
Solution Approach 2:
The side surfaces are designed with specific dimensions and positioning to optimize friction contact with cargo sides. The local contact quality is enhanced by creating multiple discrete contact zones along the beam length rather than relying on a single large contact area.

AI summary
An elongate beam assembly for supporting cargo is provided. The beam assembly includes an elongate beam extending between first and second ends, the beam comprising a bottom wall with a downward facing surface and extending across a bottom width. A top wall includes an upwardly facing surface and extends across a top width between right and left edges and opposite right and left side walls extend between the bottom and top walls. The bottom width is smaller than the top width. Each of the right and left edges of the top wall define respective right and left side surfaces. Right and left ribs extend from a bottom edge of each respective right and left side surface to the respective right and left side wall.
