Modular Pallet Clamping Assembly for Nesting and Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wooden pallets in the freight and logistics industry face issues such as nail pull-through, nail pull-out, and splitting of deck boards, which hinder repair, refurbishment, disassembly, and disposal, and require large storage volumes due to non-nesting designs.
Innovation Solution
A Modular Pallet System using a clamping mechanism with nested metal components and threaded fasteners for assembly, allowing rapid disassembly and reassembly without nails, enabling compact storage and versatile reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If nails are used to assemble wood pallets, then manufacturing cost is low and assembly speed is fast, but pallet defects occur (nail pull-through, nail pull-out, splitting) and repair/refurbishment is hindered
Solution Approach 1:
The patent removes nails entirely from the pallet assembly system and replaces them with a mechanical clamping mechanism using telescoping stringers and cam-locked deck boards, eliminating the source of nail-related defects while maintaining assembly efficiency
Solution Approach 2:
The invention changes the fundamental assembly mechanism from nail penetration to mechanical clamping through telescoping motion and cam locking, transforming how structural members are joined without compromising assembly speed
2Productivity
If nails are used to assemble wood pallets, then initial assembly is fast, but disassembly and reconfiguration are difficult
Solution Approach 1:
The pallet is divided into separable modular components (stringers and deck boards) connected by reversible mechanical fasteners, allowing individual parts to be easily removed and reconfigured without damaging other components
Solution Approach 2:
The clamping mechanism transitions from locked to unlocked state through cam rotation, enabling rapid disassembly and reassembly while maintaining structural integrity during use, making the connection dynamic rather than permanent
3Strength
If traditional wood pallet design is used, then structural strength is sufficient, but storage volume is large due to non-nesting
Solution Approach 1:
The telescoping stringer design allows one stringer to be inserted within another, enabling compact nesting of pallet components during storage and transport while maintaining full structural strength when deployed
Solution Approach 2:
The stringers transition between extended (for load-bearing) and retracted (for nesting) states, providing dynamic volume adjustment that reduces storage requirements without compromising structural integrity during use
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system facilitates easy repair, reconfiguration, and recycling of pallets, reduces damage to goods, extends service life, and allows for efficient storage and shipping by eliminating nails, while providing secure clamping forces exceeding traditional nails.
Implementation Method 1
The inner and outer stringers are actuated to translate in relation to each other. The preferred embodiment comprises nested metal components and the method of actuation is based on threaded fasteners
