Shock-absorbing Pallet Structure with Folded Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation pallets with cushioning members that use protrusions in holes on corrugated fiberboards are prone to tearing when subjected to lateral forces during transport, which can damage the product being carried.
Innovation Solution
A shock-absorbing structure featuring an underlay with positioning portions having slopes inclined to fix the cushioning member in place, supported by folded pieces that hook onto edges of holes in the corrugated fiberboard, preventing the cushioning member from being displaced or torn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If protrusions of the cushioning member are received in holes of the corrugated fiberboard to fix the cushioning member in position, then the cushioning member can be positioned accurately, but the protrusions may be torn when receiving lateral forces during transportation
Solution Approach 1:
The positioning portion is divided into multiple folded pieces (first folded piece, second folded piece, etc.) that are hooked onto edges of holes in the corrugated fiberboard. This segmentation distributes the lateral force across multiple connection points rather than concentrating it on single protrusions, preventing tearing while maintaining positioning accuracy.
Solution Approach 2:
The positioning portion transitions from a flat state to a three-dimensional structure with folded pieces extending in multiple directions. These folded pieces hook onto edges of holes, creating a multi-dimensional connection that resists lateral forces more effectively than simple protrusions while maintaining precise positioning.
2Device complexity
If the cushioning member is fixed using simple protrusions in holes, then the structure is simple, but the cushioning member and product may be displaced when receiving lateral forces
Solution Approach 1:
The positioning portion is designed to be flexible rather than rigid. The folded pieces can deform elastically when lateral forces are applied, allowing the structure to absorb shocks and maintain stability without breaking. This dynamic behavior provides both simplicity and stability.
Solution Approach 2:
The positioning portion is made from the same cushioning material as the main body, creating a composite structure that combines the cushioning properties with positioning functionality. This integrated design maintains structural simplicity while enhancing position stability through the material's inherent properties.

AI summary
A shock-absorbing structure includes an underlay placed on a base, and a cushioning member disposed on the underlay. The underlay includes at least one positioning portion that includes a slope raised in a position inclined with respect to another area of the positioning portion and fixes the cushioning member in position, and a support portion that supports the slope in an obliquely raised position. The cushioning member includes at least one hollow that receives the positioning portion.
