Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-vibration pallets face challenges in effectively reducing low-frequency vibrations and shocks due to the limitations of stiffness and mass-related performance issues in existing mounts, and air spring systems are complex, costly, and difficult to maintain.
Innovation Solution
An anti-vibration pallet design featuring a main mount at the center and auxiliary mounts outside, formed of elastic bodies, which change the direction and magnitude of elastic force based on compression, and an adjusting bolt to control the height of the upper block for optimal anti-vibration performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the stiffness of the mount is increased to support a load, then the load support capability is improved, but the lower bound in the low frequency increases making it difficult to reduce low frequency vibration or shock
Solution Approach 1:
The patent uses air springs (pneumatic elements) as the mount to replace traditional mechanical springs. The air spring system uses compressed air to provide the supporting force, allowing the mount to support loads while maintaining low stiffness characteristics that enable effective low frequency vibration reduction. The air spring's compressible gas volume provides the necessary compliance without requiring high mechanical stiffness.
2Object-affected harmful factors
If a mount having a low stiffness is used to reduce low frequency vibration/shock, then the vibration reduction performance is improved, but the height of the mount must be excessively increased due to high amount of deflection
Solution Approach 1:
The air spring mount uses pneumatic pressure to provide support force, enabling low stiffness with compact dimensions. The compressible air volume inside the spring allows significant deflection for vibration isolation without requiring excessive physical height, solving the space constraint problem while maintaining effective low frequency vibration reduction capability.
3Object-affected harmful factors
If an air spring mount using air pressure is used to support high load with excellent low frequency anti-vibration performance, then the anti-vibration performance is improved, but the structure becomes complex and maintenance becomes difficult due to additional components such as compressor, accumulator, air valve block
Solution Approach 1:
The patent extracts and eliminates the complex auxiliary components (compressor, accumulator, air valve block) from the air spring system. By using a simplified air spring design that relies on pre-compressed air or passive pressure equalization, the system maintains excellent low frequency anti-vibration performance while significantly reducing structural complexity and maintenance requirements.
Solution Approach 2:
The air spring mount is designed to operate autonomously without requiring external power sources or complex control systems. The air spring automatically adjusts to load changes and vibration conditions through its inherent pneumatic characteristics, eliminating the need for active compression systems, sensors, and control valves, thereby simplifying the overall structure.
4Strength
If an air spring mount is used to support high load, then the load support capability is improved, but the volume becomes too large making it difficult to apply to a pallet
Solution Approach 1:
The air spring mount uses pneumatic pressure to achieve high load support capability in a compact volume. The compressible air provides the necessary force multiplication, allowing the mount to support heavy loads without requiring large mechanical structures or excessive material volume, making it suitable for application on pallets where space is limited.
