Solution Overview

Problem

Conventional vibration damping solutions for server fans are inadequate, often compromising heat dissipation ability or increasing costs, as they fail to effectively reduce vibrations while maintaining reading/writing efficiency in server hard disks.

Innovation Solution

A vibration damper structure comprising a support body, fixing seat, and elastic member, where the elastic member is positioned between the support body and fixing seat, absorbing vibrations transmitted through the bearing, utilizing a hydraulic, pneumatic, or spring damper to minimize axial movement and enhance damping efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a cushion pad or vibration damping material is added to the fan support, then vibration is reduced, but heat dissipation ability is sacrificed

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The patent introduces an elastic member as an intermediary element between the support body and the fixing seat. This elastic member specifically targets vibration damping while maintaining thermal conductivity pathways for heat dissipation, thus resolving the contradiction between vibration reduction and heat dissipation capability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical state and properties of the damping material by using an elastic member with specific elasticity parameters. This allows the material to provide vibration damping while maintaining sufficient rigidity for heat conduction, transforming the material properties to satisfy both requirements

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If a cushion pad or vibration damping material is added to the fan support, then vibration is reduced, but device complexity and cost increase

Engineering Contradiction:
ImprovevibrationVSAvoidmechanical component complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the vibration damping function with the existing support structure by integrating the elastic member into the connection between the support body and fixing seat. This combination approach reduces the need for separate, additional components while achieving effective vibration damping

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elastic member is designed to inherently provide vibration damping through its elastic properties without requiring additional active control systems or complex mechanical structures. The material itself performs the damping function through its natural elasticity, simplifying the overall system

Inventive Principle:
Principle #25Self-service
