Pallet With Variable Density Elastic Components For Vibration Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pallets lack effective vibration and impact absorption, which can lead to instability and damage during transportation, especially when handling heavy or sensitive goods.
Innovation Solution
The pallet incorporates elastic components of varying densities, with the first elastic component having a lower density than the second and third components, allowing for greater deformation and better absorption of external forces while maintaining stability, and includes features like recesses and protrusions to manage deformation and adhesive components for attaching a ramp for easier goods movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pallets are used without elastic components, then the structure is simple and easy to manufacture, but vibration and impact absorption is insufficient leading to instability during transportation
Solution Approach 1:
The patent applies parameter changes by varying the density of elastic components at different locations. The first elastic components have a first density while the second elastic components have a second density that is different from the first density, allowing optimization of vibration absorption characteristics without adding complex mechanisms.
Solution Approach 2:
The patent implements local quality by positioning elastic components with different densities at specific locations. The second elastic components are positioned closer to the edge of the second board than the first elastic components, creating localized variations in mechanical properties to address specific vibration and impact issues at different areas of the pallet.
2Reliability
If elastic components of uniform density are used, then the structure is simple, but the ability to absorb different magnitudes of external forces is limited
Solution Approach 1:
The patent changes the density parameter of elastic components to create a gradient structure. By using elastic components with different densities at different positions, the system can absorb a broader range of external forces - lower density components for lighter impacts and higher density components for heavier impacts, thereby improving overall vibration and impact absorption capability.
Solution Approach 2:
The patent applies local quality by assigning different density characteristics to elastic components based on their positions. The second elastic components closer to the edge have different density properties than the first elastic components, allowing each location to be optimized for the specific types of forces it is most likely to experience during transportation.
3Reliability
If the pallet uses a single board structure, then the structure is simple and cost-effective, but it cannot provide adequate protection for heavy or sensitive goods during transport
Solution Approach 1:
The patent employs parameter changes by incorporating multiple boards with different physical characteristics. The first board and second board are connected through elastic components, creating a multi-layer structure that provides progressive cushioning and protection for goods, particularly effective for heavy or sensitive items that require enhanced protection.
Solution Approach 2:
The patent utilizes composite material principles by combining multiple boards with elastic components to create a composite pallet structure. This composite construction integrates rigid boards for structural support with elastic components for shock absorption, providing comprehensive protection for transported goods while managing the complexity through systematic design.
