Composite Carrying Pallet Structure for Heavy Loads and Dense 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, and they occupy excessive space when stacked due to the distance between upper and lower pallets.
Innovation Solution
A carrying pallet with a frame and support structure composed of various structural forms, including first, second, third, and fourth structures, featuring embedded columns and U-shaped profiles, which enhance stability and carrying capacity, and feet with guide portions and support portions to minimize stacking space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic pallets or wooden pallets are used, then the pallet structure is simple and cost is low, but the carrying capacity is limited and cannot handle loads exceeding ten tons
Solution Approach 1:
The patent combines steel beams (first beam, second beam) with concrete (poured into the steel frame) to create a composite pallet structure. The steel provides tensile strength and structural framework, while the concrete provides compressive strength and mass, together enabling the pallet to withstand loads exceeding ten tons while maintaining structural integrity
Solution Approach 2:
The pallet is divided into distinct functional components: first beams forming the outer frame, second beams creating internal support structures, feet for load distribution, and a panel for cargo placement. This segmentation allows each component to be optimized for its specific function while contributing to the overall high carrying capacity
2Strength
If standard iron pallets are used to increase carrying capacity, then the carrying weight is improved, but the structure becomes complex and special steel frames need to be manufactured
Solution Approach 1:
Instead of using complex special steel frames, the patent employs a composite structure where simple steel beams are combined with concrete. The steel beams form a straightforward framework that is easier to manufacture, while the concrete infill provides the necessary strength and weight, achieving high carrying capacity without requiring complex steel frame designs
Solution Approach 2:
The patent changes the material parameters by introducing concrete into the steel frame structure. This parameter change (from pure steel to steel-concrete composite) allows the use of simpler, more easily manufactured steel beams while achieving the required carrying weight through the combined properties of the composite material
3Volume of moving object
If wooden pallet feet or plastic pallet feet are used, then the pallet structure is simple, but the distance between upper and lower pallets is large when stacked, occupying excessive space
Solution Approach 1:
The feet are designed with a vertical extension that protrudes downward from the pallet base. This dimensional extension into the vertical space below the pallet allows the upper pallet to rest directly on these extended feet, eliminating the need for large clearance space between stacked pallets and optimizing vertical stacking density

AI summary
A carrying pallet is provided. The carrying pallet includes a frame, a support structure and multiple feet. The frame includes multiple first beam frames which are connected in sequence in an end to end manner. The support structure includes multiple second beam frames which are distributed side by side and at intervals. Each of the feet is installed between every two adjacent first beam frames. Each of the first beam frames and the second beam frames adopts any one of a first structure, a second structure, a third structure and a fourth structure.
