Fan Frame Wire Arrangement Mechanism for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire arrangement mechanisms for heat-dissipation fans are prone to power wire separation due to improper force application, leading to assembly issues and instability during operation and assembly in electronic equipment.
Innovation Solution
A wire arrangement mechanism featuring a guiding slot with holding walls and an arranging slot that is staggered and communicated with the guiding slot, forming a closed area with a confining portion to securely hold the power wire, preventing separation from the fan frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the arranging slot corresponds exactly to the guiding slot to form an open structure, then the wire arrangement mechanism is simple and easy to manufacture, but the power wire can be easily separated from the frame through the arranging slot when subjected to improper force
Solution Approach 1:
The wire arrangement mechanism is divided into two distinct slots: a guiding slot for initial wire placement and an arranging slot for final wire positioning. This segmentation allows each slot to have specialized functions, with the arranging slot being staggered to provide closure while the guiding slot facilitates easy wire insertion during assembly.
Solution Approach 2:
The arranging slot is positioned staggered relative to the guiding slot rather than aligning directly with it. This dimensional offset creates a closed-loop structure that prevents wire separation while maintaining manufacturing simplicity, as the slots are formed on different surfaces of the frame rib.
2Strength
If the wire arrangement mechanism is formed on ribs of the frame, then it provides structural support and protection, but the power wire may still be separated due to vibration or wind force during operation
Solution Approach 1:
The wire arrangement mechanism proactively prevents wire separation by creating a closed structure with the staggered arranging slot before any harmful forces act on the wire. This preliminary structural design counteracts the potential effects of vibration and wind force that occur during fan operation.
Solution Approach 2:
The frame rib structure with integrated slots provides a flexible yet protective enclosure for the power wire. The slots are designed to accommodate the wire while the surrounding rib structure provides mechanical strength and protection against external forces during operation.
3Reliability
If the arranging slot is staggered from the guiding slot to form a closed structure, then the power wire is prevented from separating, but the device complexity increases
Solution Approach 1:
The guiding slot and arranging slot are merged into a single integrated wire arrangement mechanism formed on the frame rib. This combination provides both wire guidance and secure closure functions in one structure, preventing separation while avoiding the need for separate components that would increase device complexity.
Solution Approach 2:
The frame rib structure serves multiple functions: it provides structural support, contains the wire arrangement mechanism, and forms both the guiding and arranging slots. This self-service approach eliminates the need for additional dedicated wire management components, maintaining simplicity while ensuring reliability.

AI summary
A wire arrangement mechanism including a guiding slot and an arranging slot is formed on a fan frame. The guiding slot includes a bottom wall and two holding walls extending therefrom. The arranging slot is defined by an outer frame and a confining portion connected thereto. The arranging slot is staggered from and communicated with the guiding slot.
