Solution Overview

Problem

Electronic devices, such as servers, face damage from dust and particulate matter entering through openings for heat dissipation and data transmission, especially in outdoor or poorly air-conditioned environments.

Innovation Solution

A server design incorporating a dustproof device with a filtering portion and a filler with a slit structure, which are integrated into the host chassis to prevent dust from entering while allowing air for heat dissipation and accommodating transmission cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If openings are provided for heat dissipation and data transmission, then heat dissipation efficiency and connectivity are improved, but dust and particulate matter can easily enter the chassis causing damage

Engineering Contradiction:

Improveheat dissipation efficiencyVSAvoiddust entry

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The dustproof device employs a filtering portion with porous or mesh-like structure that allows air to pass through for heat dissipation while blocking dust and particulate matter. The porous material enables selective permeability - permitting gas flow while restraining solid particles, thus resolving the contradiction between ventilation and protection.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The dustproof device acts as an intermediary component installed at the openings. It mediates between the need for air flow (heat dissipation) and the need to prevent dust entry by filtering the air before it enters the chassis interior, thus protecting internal components while maintaining thermal management.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If transmission cables are routed through openings in the chassis, then data transmission and power supply are enabled, but the openings become entry points for pollution matters

Engineering Contradiction:

ImproveconnectivityVSAvoidpollution entry

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The dustproof device includes flexible sealing structures around the transmission cable passages. These flexible shells or thin film barriers conform to the cable shapes and seal the gaps between cables and chassis, preventing pollution matter from entering through cable entry points while allowing cable connectivity.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing structure provides localized protection around each transmission cable opening. Instead of sealing the entire chassis, the dustproof device applies sealing quality specifically at the cable penetration points where pollution would most easily enter, maintaining connectivity while providing targeted protection.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If a dustproof device with filtering portion is installed, then dust protection is improved, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improvedust protectionVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The dustproof device merges multiple functions into a single integrated component: filtering portion for dust removal, sealing portions for gap closure, and cable management features. By combining these functions in one device rather than using separate components, the overall system complexity is reduced while maintaining effective dust protection.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The dustproof device is designed as a multi-functional component that simultaneously provides filtration, sealing, cable routing guidance, and structural support. This universal design allows a single component to perform multiple protective and organizational functions, reducing the total number of parts and simplifying assembly.

Inventive Principle:

Principle #6Universality (Multi-functionality)
