Computer Housing Shock Absorber for Vibration Source Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rubber cushion-based shock absorption systems are inadequate for large-scale server or host computer housings with multiple heat dissipating fans, as they fail to provide complete shock absorption effectiveness and can lead to noise and loose internal components due to inadequate vibration mitigation.
Innovation Solution
A computer housing shock absorber device utilizing shock absorber elements connected between an outer fixing frame with heat dissipating fans and an inner fixing frame, and a U-shaped holding space, which absorbs vibratory moments and forces through cylindrical bodies with recessed circular grooves and connecting posts, effectively reducing noise and stabilizing internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rubber cushions are used as shock absorbers in conventional computer housings, then the structure is simple and easy to manufacture, but the shock absorption effectiveness is insufficient for large-scale servers with multiple heat dissipating fans
Solution Approach 1:
The shock absorption system is divided into multiple independent shock absorber elements distributed at different locations (front, rear, left, right sides) of the computer housing. Each shock absorber element independently absorbs vibrations from heat dissipating fans, providing comprehensive shock absorption coverage throughout the entire housing structure rather than relying on a single rubber cushion.
Solution Approach 2:
The shock absorber elements serve as intermediary components positioned between the heat dissipating fans (vibration sources) and the computer housing structure. These intermediaries absorb and dampen vibratory forces before they can be transmitted to the housing, effectively isolating the housing from vibration-induced damage and noise.
2Temperature
If multiple heat dissipating fans are installed in large-scale servers, then the cooling performance is improved, but the vibratory forces and noise increase
Solution Approach 1:
The invention converts the harmful vibratory forces generated by heat dissipating fans into beneficial shock absorption effects. By strategically positioning shock absorber elements near the fans, the vibratory energy that would otherwise cause damage and noise is captured and dissipated by the shock absorbers, transforming a harmful byproduct of improved cooling into a controlled energy dissipation mechanism.
3Reliability
If conventional rubber shock absorbing cushions are used, then the device complexity is low, but the internal components may become loose due to insufficient vibration mitigation
Solution Approach 1:
Instead of using a uniform shock absorption approach throughout the housing, the invention applies shock absorber elements specifically at local positions where heat dissipating fans generate vibrations. This targeted local quality approach ensures that components in high-vibration zones are protected, preventing them from becoming loose, while avoiding unnecessary complexity in areas where vibration is not an issue.
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 solution significantly reduces vibratory forces on the entire computer housing, minimizes noise, and prevents internal components from becoming loose by effectively absorbing torsional and vibratory moments, ensuring comprehensive shock absorption in large-scale computer systems.
Implementation Method 1
The vibratory moment produced when the heat dissipating fans are rotating is transmitted outward through the outer fixing frame and absorbed by a plurality of the shock absorber elements, thus, the vibratory force on the entire computer housing is substantially reduced
