Foldable Corrugated Paperboard Corner Shroud for Recyclable Pallet Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corner boards used for protecting and stabilizing pallet loads during shipping are not recyclable, leading to disposal issues and increased costs due to their non-recyclable nature.
Innovation Solution
A foldable corrugated paperboard corner shroud with a three-layer structure, comprising outer, middle, and inner layers, that can be folded to form a corner shroud or integrated side walls, allowing for recyclability and enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional corner boards are used to protect and stabilize pallet loads, then stability and protection are improved, but recyclability deteriorates
Solution Approach 1:
The corner board is divided into multiple flaps (first flap, second flap, third flap, fourth flap) that can be folded and assembled around the pallet load corners. This segmentation allows the single piece of corrugated material to wrap around and secure multiple corners while maintaining structural integrity and recyclability.
Solution Approach 2:
The corner board assembly serves multiple functions: it protects four corners of a pallet load simultaneously, provides stacking stability, and maintains recyclability. The same structure can be applied to different pallet sizes and load types, making it a universal solution replacing traditional non-recyclable corner boards.
2Strength
If corner boards are made with multiple layers and glue for rigidity, then strength is improved, but recyclability deteriorates
Solution Approach 1:
The corner board uses a single layer of corrugated material rather than multiple glued layers. The rigidity and strength are achieved through the folding geometry and assembly structure rather than through material layering and adhesive bonding, eliminating glue contamination and maintaining full recyclability.
3Loss of substance
If traditional corner boards are reused, then resource waste is reduced, but adaptability deteriorates due to length limitations
Solution Approach 1:
The corner board is designed as a dynamic, foldable structure that can be assembled and disassembled. This allows the same corner board to be taken apart and reconfigured for different pallet sizes and load requirements, providing adaptability that rigid traditional corner boards cannot achieve while still reducing waste through reuse.
