Fan Waterproof Structure With Enclosed Wire Support Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan waterproof structures fail to effectively protect electrical wires from humidity and mechanical stress, leading to breakage and loss of waterproof integrity due to incomplete enclosure and over-pulling issues.
Innovation Solution
A fan waterproof structure featuring a frame body with a base seat and circumferential wall, where first and second support members form a rib or static blade structure to fully enclose the electrical wire within a waterproof plastic layer, preventing breakage and over-pulling, and enhancing the waterproof effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof plastic layer is formed by plastic potting or insert integral injection to enclose the stator assembly, then the stator assembly is isolated from the outer environment, but the electrical wire is exposed to the outer side and the waterproof plastic layer is apt to break off when pulling the electrical wire
Solution Approach 1:
The electrical wire is nested within the second support member that extends from the waterproof plastic layer to the circumferential wall, creating a protected pathway. The wire is enclosed within the support member structure rather than being exposed, while the support member itself is integrated into the waterproof enclosure system.
Solution Approach 2:
The support members extend horizontally from the base seat to the circumferential wall, creating a three-dimensional protective structure. The electrical wire is routed through this spatial structure rather than being simply attached to the surface, adding dimensional protection against pulling forces.
2Ease of operation
If the electrical wire is conducted through an opening of the base seat and received in a half-open receiving channel, then the wire outlet is accessible, but the electrical wire is apt to be over-pulled and the wire outlet is easy to break off
Solution Approach 1:
The electrical wire is nested within the second support member that provides a protected conduit from the waterproof plastic layer to the circumferential wall. This nested structure prevents direct exposure and over-pulling at the wire outlet while maintaining accessibility.
Solution Approach 2:
The support member structure serves as a pre-established protective cushion for the electrical wire connection. By providing this protective structure before the wire is installed and connected, the system prevents over-pulling and breakage rather than relying on post-installation reinforcement.
3Ease of operation
If only a small part of the electrical wire is enclosed in the waterproof plastic layer, then the wire remains accessible for connection, but humidity is easy to infiltrate into the stator assembly to cause damage
Solution Approach 1:
The electrical wire is nested within the second support member that extends through the waterproof plastic layer to the circumferential wall. This creates a continuous protected pathway that prevents humidity infiltration along the wire while maintaining wire accessibility for connection at the circumferential wall location.
Solution Approach 2:
The waterproof plastic layer acts as a flexible protective shell that encloses the electrical wire within the second support member. This shell structure provides continuous waterproof protection along the wire pathway while allowing for wire installation and connection.

AI summary
A fan waterproof structure includes a frame body and a stator assembly to configure as two individual components. The frame body has a base seat and a circumferential wall. Multiple first support members horizontally extend from the base seat to connect with the circumferential wall. The stator assembly is disposed on the base seat and has an electrical wire. A waterproof plastic layer is disposed on the stator assembly to enclose the stator assembly. A second support member horizontally extends from the waterproof plastic layer to connect with the circumferential wall. The electrical wire is disposed in the second support member to achieve good waterproof effect.
