Solution Overview

Problem

Existing methods for integrating fans into electronic devices are either difficult to replace or appear as temporary solutions, limiting the lifespan and reliability of the devices due to compact but hard-to-replace internal fans and externally mounted fans that are prone to damage.

Innovation Solution

A plug connector system that allows for the compact and retrofittable integration of fans into electronic devices, where the fan is mounted with the power supply connector, enabling easy replacement and monitoring through a diagnostic circuit, and providing uninterrupted power supply with a fan connection that branches off from the device's voltage supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a fan is firmly integrated into the device housing structure, then the fan can be compactly housed within the device housing, but replacing or repairing the fan becomes very difficult

Engineering Contradiction:
Improveinstallation spaceVSAvoidfan replacement
Core Design Contradiction:
Volume of moving objectVSEase of repair

Solution Approach 1:

The connector housing is divided into separate functional components: the main connector body and a detachable fan mounting module. The fan is mounted on a mounting plate that can be independently removed from the connector housing, allowing the fan to be replaced without replacing the entire connector assembly. This segmentation enables compact integration while maintaining ease of repair.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If a fan is retrofitted to the housing of an electronic device, then the fan can be easily replaced, but the solution appears temporary and can be easily damaged by external components

Engineering Contradiction:
Improvefan replacementVSAvoidintegration stability
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The fan mounting function is merged with the connector housing structure. The fan mounting plate is integrated into the connector housing as a unified assembly, combining the electrical connection function with the mechanical mounting function. This merging provides a permanent, reliable integration that eliminates the temporary appearance of retrofit solutions while maintaining replaceability.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the power supply slot is used for both mechanical attachment and electrical connection, then no additional brackets are required, but the input and output accessibility may be limited

Engineering Contradiction:
Improvemounting structureVSAvoidinput and output accessibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The input and output connectors are positioned in different spatial dimensions relative to the power supply slot. The input connector is accessible from the front face while the output connector is positioned on the side face, allowing both to be accessed without interfering with each other or requiring disassembly of the mounting structure. This multi-dimensional arrangement maintains simplicity while ensuring accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
