Pallet Stringer Board Non-Contact Zones Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pallets often suffer from deflection and potential breakage of loads with casters when subjected to impact loads during transportation, as the concentrated force is not effectively distributed, leading to increased risk of damage.
Innovation Solution
The pallet design incorporates stringer boards with oblique slits and cutout portions that create non-contact regions with the top board, allowing for shock absorption and distributing impact loads, and optionally includes buffer members for enhanced elasticity, ensuring the top board maintains contact with the load while reducing deflection and enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the stringer board is in full contact with the top board, then the structural strength is improved, but the impact load concentration increases causing top board deflection and load damage
Solution Approach 1:
The stringer board is segmented into multiple contact portions and non-contact portions along its length. This segmentation allows the board to maintain structural strength through contact zones while creating shock-absorbing non-contact zones that prevent impact load concentration on the top board, thereby resolving the contradiction between strength and impact protection.
Solution Approach 2:
The non-contact portions are positioned beforehand at specific locations on the stringer board to act as pre-planned shock absorption zones. These zones are strategically placed to intercept and dissipate impact loads before they can concentrate on the top board, providing beforehand cushioning that prevents deflection and load damage while maintaining overall structural integrity.
2Object-affected harmful factors
If non-contact portions are added to the stringer board, then shock absorption is improved, but the device complexity increases
Solution Approach 1:
The stringer board is divided into alternating contact and non-contact portions along its longitudinal axis. This segmentation creates multiple shock absorption zones without requiring additional components, as the non-contact portions are simply gaps in the otherwise continuous board structure, thereby achieving shock absorption with minimal increase in device complexity.
Solution Approach 2:
Different portions of the stringer board are given different local qualities: contact portions provide structural support and rigidity, while non-contact portions provide shock absorption and flexibility. This local differentiation allows the single stringer board to perform multiple functions without requiring a complex assembly of separate components.

AI summary
A pallet includes at least one top board on which a load is to be placed and at least one substantially plate-shaped stringer board that is provided independently of the top board and that has at least one non-contact portion, which is not in contact with the top board in a region between the stringer board and the top board, the stringer board being in contact with the top board in a vertical direction.
