Anti-sagging Beam Connectors for Pallet Structural Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-sagging solutions for pallets do not effectively address the sagging issue while maintaining the lightweight and nestable features, and often require additional vertical dimension or compromise structural stability when used with forklifts.
Innovation Solution
The development of anti-sagging devices with beam-like structures and connectors that securely attach to pallet legs, providing structural firmness and allowing for four-way lifting, without increasing the vertical dimension, and enabling secure racking and shelving without sagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If anti-sagging devices are added to pallets to prevent sagging when racked, then structural stability is improved, but the vertical dimension increases
Solution Approach 1:
The anti-sagging device transitions from a vertical support structure to a horizontal beam-like structure that spans between pallet legs. This dimensional change allows the device to prevent sagging by distributing loads horizontally across the pallet deck rather than adding vertical height, thus maintaining compatibility with racking systems while providing structural stability.
Solution Approach 2:
The beam-like structure incorporates flexibility to accommodate slight deformations and movements of the pallet legs without compromising overall structural stability. This dynamic characteristic allows the anti-sagging device to adapt to variations in pallet geometry and loading conditions while maintaining its load-bearing function.
2Reliability
If anti-sagging devices are added to provide structural firmness, then reliability is improved, but device complexity increases
Solution Approach 1:
The anti-sagging device merges multiple functions into a single integrated structure: it acts as a load-bearing beam, a connector between pallet legs, and a reinforcement element for the pallet deck. This consolidation achieves structural firmness without proportionally increasing device complexity, as one component performs multiple critical functions simultaneously.
Solution Approach 2:
The beam-like structure serves multiple purposes: preventing sagging, distributing loads, reinforcing the pallet deck, and potentially providing attachment points for other accessories. This multi-functionality increases reliability while minimizing the addition of separate components, thereby controlling device complexity.
3Stability of the object's composition
If connectors are added to attach anti-sagging devices to pallet legs, then stability is improved, but manufacturing complexity increases
Solution Approach 1:
The connectors are designed to nest within or attach to the existing pallet leg structure rather than requiring separate mounting operations. This nesting approach allows the anti-sagging device to be integrated with the pallet legs in a single assembly step, improving stability while minimizing additional manufacturing complexity.
Solution Approach 2:
The connectors are designed to self-align and self-secure to the pallet legs through features such as snap-fits, friction locks, or gravity-assisted attachment. This self-service capability eliminates the need for complex fastening mechanisms or additional assembly tools, thereby improving stability without significantly increasing manufacturing complexity.

AI summary
An anti-sagging device, configured to conform with a lightweight pellet, is described. Details of assemblies of a lightweight pellet and the novel anti-sagging devices are further described. An assembly of a lightweight pellet and the novel anti-sagging devices is characterized by superior structural firmness, so that upon placing the assembly onto two side-beams of a racking or shelving structure, the assembly effectively does not sag remains essentially planar or linear.
