Solution Overview

Problem

Existing computer illumination fans suffer from poor electrical connections that lead to oxidation and wear, resulting in frequent breakdowns and the need for complete replacement, which is wasteful and reduces service life.

Innovation Solution

A parallel-connected lighting fan design featuring an outer frame with slots and guide rails, plug-in electrical connectors with magnetic and positioning members, and spring-pin electrodes for secure, easy connection of multiple fans, allowing for quick assembly and disassembly without requiring replacement of the entire fan.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the connectors are fixed on the body of the fan, then the electrical connection is stable, but the connectors are easy to be oxidized and worn-out after being used for a period of time, leading to poor contact or breakdown

Engineering Contradiction:
Improveelectrical connection stabilityVSAvoidservice life of connectors
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent divides the fan into separable modules: the fan body and the connector are detached from each other. The connector is removed from the fan body and integrated into the power socket, allowing the fan blade assembly to be separated for replacement without replacing the entire fan, thus extending service life while maintaining connection stability during operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transforms the static fixed connector into a dynamic removable component. The connector can be detached from the fan body and reattached to the power socket, enabling flexible maintenance and replacement. This dynamic design allows the connector to be separated when oxidized or worn, preventing complete system failure.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the whole illumination fan is replaced when connectors breakdown, then the electrical connection problem is solved, but it is wasteful and the service life of the illumination fan is affected

Engineering Contradiction:
Improveelectrical connection functionalityVSAvoidwaste of fan components
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent segments the fan system into replaceable modules: the fan blade assembly can be separated from the motor housing and power socket. When connectors breakdown, only the necessary components (connector and power socket) need replacement, not the entire fan, reducing waste and extending overall system service life.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent enables selective replacement of worn connectors and power sockets while retaining functional components like the fan blade and motor housing. This allows recovery and reuse of still-functional parts, reducing waste and promoting resource efficiency.

Inventive Principle:
Principle #34Discarding and recovering

3Device complexity

If only locking hooks are used for connection, then the structure is simple, but the whole structure strength is weak and the connection is not secure

Engineering Contradiction:
Improveconnection structure simplicityVSAvoidconnection strength
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The patent merges multiple connection functions into an integrated power socket assembly that combines electrical connection (via connectors) and mechanical support (via power socket housing). This unified structure provides both electrical functionality and structural strength, securing the fan blade assembly firmly to the motor housing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The power socket serves multiple functions: it provides electrical connection through integrated connectors, structural support for the fan blade assembly, and mounting attachment. This multi-functional design simplifies the overall connection structure while enhancing connection strength and security.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Strength

If screwdrivers or tools are required for disassembly, then the connection is secure, but the components are inconvenient to use for quick assembly and disassembly

Engineering Contradiction:
Improveconnection securityVSAvoidassembly and disassembly convenience
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent transforms the static screw-fastened connection into a dynamic snap-fit or plug-and-play connection system. The power socket and connector are designed to be easily attached and detached by hand without tools, enabling quick assembly and disassembly while maintaining secure connection during operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the connection system into modular components (connector, power socket, fan blade assembly) that can be independently assembled and disassembled. This modular design with standardized interfaces allows tool-free quick connection while maintaining structural integrity during use.

Inventive Principle:
Principle #1Segmentation

AI summary

A parallel-connected lighting fan which includes an outer frame, an electric motor and a fan blade arranged at a center of the outer frame, a plug-in electrical connector, and a light emitting member is provided. The outer frame is provided with a plurality of slots. When the two lighting fans of the same type are connected in parallel, the two slots of the two outer frames adjacent to each other form a linked slot. Both the plug-in electrical connector and the slot are provided with corresponding electrodes. The lighting fans of the same type can be connected in parallel conveniently, quickly, and reliably by the plug-in electrical connector being inserted into the linked slot in a plug-in direction, without coming off easily. The replaceable design of the plug-in electrical connector allows easy replacement and maintenance during loss or failure.
