Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle strut assemblies experience resonance frequencies that amplify vibrations, leading to mechanical resonance and potential premature failure, which existing technologies have not effectively addressed.
Innovation Solution
A vibration attenuation assembly featuring a strut weight with a conical upper surface and a central rod receiving opening, attached to the upper end of the strut assembly, which alters the resonance frequency of the strut assembly to prevent vibration propagation by changing its natural frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional strut assembly is used, then the vehicle structure is simple, but resonance frequencies amplify vibrations causing mechanical resonance and potential premature failure
Solution Approach 1:
The patent applies parameter changes by adding a mass element (strut weight) to alter the natural frequency of the strut assembly. This changes the dynamic parameters of the system to avoid resonance conditions, thereby improving reliability without fundamentally changing the strut assembly structure.
Solution Approach 2:
The patent converts the harmful resonance phenomenon into a benefit by strategically adding mass to shift the resonant frequency away from excitation frequencies. The vibration and resonance effects are not eliminated but redirected to a beneficial frequency range that prevents premature failure.
2Object-affected harmful factors
If vibration attenuation is implemented, then vibration propagation is reduced, but the device complexity increases
Solution Approach 1:
The strut weight modifies the mass parameter of the strut assembly, which directly changes the natural frequency and vibration characteristics. This simple parameter change effectively reduces vibration propagation to the vehicle body without requiring complex vibration isolation systems.
Solution Approach 2:
The vibration attenuation function is segmented into a separate, independent component (the strut weight) that can be added to the existing strut assembly. This modular approach reduces vibration propagation while minimizing the impact on overall device complexity, as the weight is a discrete add-on component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The strut weight effectively attenuates the natural vibration frequencies of the vehicle strut assembly, reducing mechanical resonance and enhancing the vehicle's operating experience by preventing vibration propagation to the vehicle body structure.
Implementation Method 1
All structures have one or more resonance resonant frequencies. A resonance resonant frequency is a natural frequency of vibration present in any object or structure.
Implementation Method 2
The strut weight effectively attenuates the natural vibration frequencies of the vehicle strut assembly, reducing mechanical resonance and enhancing the vehicle's operating experience by preventing vibration propagation to the vehicle body structure.
