Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration damping solutions for sensitive devices during transportation are inadequate due to temperature-dependent materials and limited effectiveness across a wide temperature range, leading to insufficient damping properties outside specific temperature intervals.
Innovation Solution
A suspension assembly utilizing wire rope isolators and a damping support member, configured with inclined support plates and base arrangements, provides effective vibration isolation and damping through multiple mechanisms like isolation, friction, and absorption, maintaining damping functionality across a broad temperature range of -33°C to 63°C.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature-dependent damping materials (such as rubber and elastomers) are used to reduce vibration transfer, then damping properties are sufficient within a certain temperature interval, but damping properties become insufficient outside this temperature interval
Solution Approach 1:
The patent employs a composite damping system combining wire rope isolators (metal-based, temperature-resistant) with elastomeric damping materials. This composite approach allows the system to maintain damping properties across wide temperature ranges by leveraging the temperature stability of metal wire ropes while utilizing the vibration absorption capabilities of elastomers within their effective temperature range.
Solution Approach 2:
The patent changes the physical parameters of the damping system by introducing wire rope isolators that operate on different physical principles (friction, elasticity of metal) compared to traditional elastomeric materials. This parameter change enables the system to function reliably across extreme temperature conditions where conventional elastomers would fail.
2Reliability
If multiple damping mechanisms are implemented to ensure continuous vibration management across various temperatures, then reliable and continuous vibration management is achieved, but the structure becomes more complex
Solution Approach 1:
The wire rope isolators serve multiple functions simultaneously: they act as mechanical isolators, provide friction-based damping, and maintain structural integrity across temperature variations. This multi-functionality reduces the need for separate components for each damping mechanism, thereby managing complexity while ensuring reliable vibration management.
Solution Approach 2:
The patent merges the isolation function and damping function into a single integrated wire rope isolator component. By combining these functions that were traditionally provided by separate components, the system achieves reliable continuous vibration management without proportionally increasing structural complexity.
