Euro Pallet Support Frame for Stable Multi-Layer Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pallet shelf systems lack flexibility and stability during transport, particularly when lifting and moving multiple layers of pallets, leading to instability and difficulty in loading and unloading, especially when using crosswise fork pockets.
Innovation Solution
A support frame system for euro pallets that engages both longitudinal and crosswise fork pockets, allowing forklifts to lift the upper pallet by engaging the outer pallet legs, with stabilizing features like spikes and barbs to prevent movement during transport, and modular design for easy extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If pallet shelf systems use multiple layers of pallets stacked on each other, then cargo space utilization is improved, but stability during transport deteriorates
Solution Approach 1:
The support frame is inserted into the fork pockets of the pallet, creating a nested structure where the frame fits within the pallet's existing geometry. This nesting provides structural reinforcement while maintaining compact dimensions, enabling stable multi-layer stacking without excessive width increase.
Solution Approach 2:
The invention transitions from two-dimensional pallet stacking to three-dimensional stable stacking by adding vertical support elements (support frame with legs) that engage multiple pallets simultaneously. The support frame extends vertically to engage both upper and lower pallets, creating a three-dimensional load-bearing structure that prevents lateral movement and instability.
2Ease of operation
If pallet shelf systems are designed for easy assembly and disassembly, then flexibility is improved, but stability and security of pallet stacking deteriorates
Solution Approach 1:
The support frame serves multiple functions simultaneously: it provides structural support for stacking, engages with standard euro pallet fork pockets for compatibility, and includes stabilizing features (spikes, barbs) for security. This multi-functionality achieves both ease of operation through standard interfaces and stability through integrated securing mechanisms.
Solution Approach 2:
The support frame acts as an intermediary element between multiple pallets, providing a stable connection without requiring permanent modification to the pallets themselves. The frame's protrusions engage the pallets' fork pockets, creating a reversible but secure connection that maintains stability while allowing easy assembly and disassembly.
3Adaptability or versatility
If support frame width is reduced to comply with EU-standard truck widths, then adaptability to cargo space is improved, but stability when supporting upper pallets deteriorates
Solution Approach 1:
The support frame compensates for reduced width by utilizing the vertical dimension more effectively. The frame's legs extend vertically to engage multiple pallets, and the overall structure is designed to span the width of standard euro pallets (800mm) while maintaining a compact profile that fits within EU-standard truck width constraints.
Solution Approach 2:
The support frame is constructed from aluminum profiles with integrated stabilizing features (spikes, barbs, protrusions), creating a composite structure that combines light weight with high strength and stability. This composite design enables the frame to provide adequate support stability while maintaining a width compliant with EU-standard truck requirements.
