Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual electrical connection cords are used to connect each fan unit directly to the motherboard, then electrical connection is achieved, but the cords occupy a lot of space and tend to tangle disorderly
Solution Approach 1:
Multiple individual electrical connection cords are merged into a single integrated electrical connection structure. The fan module rack is designed with an integrated electrical connection assembly that consolidates all individual cord connections into one unified interface on the motherboard, eliminating the need for multiple separate cords and their associated routing space.
Solution Approach 2:
An intermediary electrical connection structure is introduced between the fan units and the motherboard. This intermediate assembly acts as a mediator that receives electrical connections from the motherboard and distributes them to individual fan units internally, avoiding the need for cords to extend from each fan unit to the motherboard.
2Ease of operation
If a cord covering plate is used to organize electrical connection cords, then cord organization is improved, but the cords are still extended between fan units and motherboard occupying usable space
Solution Approach 1:
The electrical connection cords are extracted from the internal structure of the fan module rack and repositioned to the external side. The electrical connection assembly is mounted on the outer surface of the fan module rack, allowing cords to be connected externally without extending through the internal space of the rack, thus preserving usable space inside.
3Manufacturing precision
If adapter circuit board is designed for specific fan unit models, then precise electrical connection is achieved, but production cost increases and sharing ratio decreases
Solution Approach 1:
The adapter circuit board is designed with universal compatibility to support multiple fan unit models and specifications. Instead of creating separate adapter boards for each fan model, a single multi-functional adapter board is developed that can accommodate different fan types through configurable electrical connection patterns and universal mounting mechanisms.
4Adaptability or versatility
If multiple different specification connectors are mounted on adapter circuit board, then wider applicability is achieved, but circuit arrangement complexity and manufacturing cost largely increase
Solution Approach 1:
The adapter circuit board utilizes parameter changes in electrical connection configurations rather than physical connector variations. By changing electrical parameters such as connection patterns, pin assignments, and circuit routing on a single board design, the system achieves compatibility with multiple fan unit specifications without requiring multiple different physical connector types.

AI summary
A quick disconnect electrical connection structure for fan module includes fan units assembled to a fan frame and respectively including an electrical connection section located facing toward an electrical connection side of the fan frame, and a fan electrical adapter board connected to the electrical connection side of the fan frame and having mating electrical connection sections provided thereon corresponding to the electrical connection sections. The mating electrical connection sections and other circuit arrangements on the fan electrical adapter board together form an external connection terminal for electrically connected to an external device. Flexible electrical cords with one or more quick disconnect electrical connectors provided thereon are used to adapt to any misalignment between the electrical connection sections and the mating electrical connection sections while quickly connect them to one another, enabling improved sharing ratio of the fan units and the fan electrical adapter board used in different working environments.
