Auto-Mount Fan Connector Structure Without Residual Wires
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan structures require manual assembly on a motherboard, leading to increased manufacturing costs and inconsistent mounting quality due to residual electrical wires, which interfere with airflow and dust accumulation.
Innovation Solution
A fan structure with a connector connection section protruding from the fan frame, allowing for automatic mounting on a system circuit board, where the fan end connector is directly pressed onto the circuit board end connector, eliminating residual wires and enabling automated assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual assembly is used for fan mounting, then flexibility in handling residual wires is maintained, but manufacturing cost increases and mounting quality becomes inconsistent
Solution Approach 1:
The electrical connection system is segmented into two parts: a first electrical connector integrated with the circuit board and a second electrical connector integrated with the fan. This segmentation allows each connector to be optimized for its specific function, with the fan-side connector designed to eliminate residual wire issues while enabling automated assembly.
Solution Approach 2:
The fan frame is merged with the second electrical connector to form an integrated assembly. This merging eliminates the need for separate wire management components and enables the entire fan assembly to be automatically mounted onto the circuit board without manual wire handling, thereby reducing manufacturing cost and improving consistency.
2Productivity
If manual wire trimming is performed, then residual wire issues are resolved, but production time increases and labor requirements increase
Solution Approach 1:
The electrical connectors are pre-assembled and pre-positioned during fan manufacturing, with the second electrical connector already integrated with the fan frame. This preliminary action eliminates the need for time-consuming wire trimming and manual connection during final assembly, thereby increasing productivity and reducing production time.
3Object-affected harmful factors
If residual electrical wires remain after fan mounting, then connection flexibility is maintained, but airflow is interfered with and dust accumulation occurs
Solution Approach 1:
The harmful residual wires are extracted and eliminated by integrating the second electrical connector directly with the fan frame. This extraction removes the source of airflow interference and dust accumulation while maintaining all necessary electrical connection functions through the integrated connector design.
4Manufacturing precision
If the fan connector is manually plugged into the motherboard connector, then connection reliability is achieved, but assembly consistency varies and labor intensity increases
Solution Approach 1:
The fan assembly with the integrated second electrical connector is designed to self-align and self-connect with the first electrical connector on the circuit board. This self-service capability ensures consistent mounting quality across all assemblies while eliminating manual plugging operations, thereby improving precision without sacrificing operational simplicity.

AI summary
A fan structure automatically mountable on a system circuit board includes a fan. The fan includes a fan frame main body. A connector connection section is disposed on the fan frame main body for connecting with a fan end connector, whereby the fan end connector can be assembled with the fan frame main body. Accordingly, when the fan is mounted on the system circuit board, the fan end connector can be directly pressed down by means of an automated device to plug into the circuit board end connector. Therefore, the manufacturing process can be automated.
