Nested Steel Pallet Structure for Heavy-Load Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrying pallets made of plastic, wooden, and standard iron materials have limited carrying capacity, especially when loads exceed ten tons, requiring special steel frames, and they occupy excessive space when stacked due to large distances between pallets.
Innovation Solution
A novel carrying pallet design featuring a frame with multiple square tubes, support pillars, and connecting plates, along with specialized feet that include guide portions and support structures, allowing for high weight capacity and minimal space occupation during stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If standard iron pallets are used to increase carrying capacity, then the carrying weight is improved, but the carrying capacity is still limited and cannot handle loads exceeding ten tons
Solution Approach 1:
The pallet is divided into multiple independent square tube components (first square tubes, second square tubes, third square tubes) that are distributed side by side and connected together. This segmentation allows the load to be distributed across multiple structural elements, enabling the pallet to handle loads exceeding ten tons while maintaining structural integrity
Solution Approach 2:
The pallet combines multiple material properties by using square tube structures with specific structural configurations. The composite structural design integrates frame structures with support structures, creating a system that achieves both high strength and adaptability for heavy loads
2Device complexity
If plastic pallets or wooden pallets are used, then the structure is simple, but the feet are integrally formed or simple wood pieces resulting in large distance between stacked pallets and excessive space occupation
Solution Approach 1:
The feet are designed with nested structures including guide portions and stretching spaces that allow the feet of upper pallets to insert into and nest within the feet of lower pallets. This nesting design eliminates the large gaps between stacked pallets, significantly reducing the overall volume occupied when pallets are stacked vertically
Solution Approach 2:
The feet structure extends in multiple dimensions with guide portions, stretching spaces, and support portions arranged vertically and horizontally. This multi-dimensional design allows for both structural simplicity and efficient stacking by utilizing vertical space effectively while maintaining ease of manufacture
3Strength
If square tube structures are used in the frame and support structure, then torsion and bending resistance is enhanced, but the structural complexity increases with multiple components
Solution Approach 1:
Multiple square tube components (first square tubes, second square tubes, third square tubes) are merged into a unified frame structure where they are connected through joints and support pillars. This merging approach maintains the high torsion and bending resistance of individual square tubes while creating an integrated structure that functions as a cohesive unit, balancing strength with manageable complexity

AI summary
A novel carrying pallet is provided. The novel carrying pallet includes a frame and a support structure located inside the frame. The support structure includes multiple first square tubes, multiple support pillars and a connecting plate. The multiple first square tubes are distributed side by side, and two ends of each of the multiple first square tubes are connected with the frame. An outer side of the connecting plate is connected with the frame. The multiple support pillars are located on the multiple first square tubes and are vertically arranged. The multiple support pillars are connected with the first square tubes and the connecting plate. A foot is arranged at a corresponding one corner of the frame.
