Ceiling Fan Swing Structure With Reduction Motor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling fans often experience slippage or disengagement due to weight or prolonged use, and manual angle adjustment is required for multiple-rotor fans, which is labor-intensive and limits air circulation effectiveness.
Innovation Solution
A swing structure incorporating a reduction motor with a driving wheel, connecting rod, and bearing system that allows for controlled swing velocity and adjustable mounting angles, enabling the ceiling fan to swing rightward and leftward without affecting the fan motor's rotating velocity, while maintaining aesthetic integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gear unit is installed at the rear side of a fan motor to carry out swing motion, then the ceiling fan can swing rightward and leftward, but the gear unit may produce slippage or disengagement if the ceiling fan is overweight or used for a long period of time
Solution Approach 1:
The patent replaces the traditional gear unit with a reduction motor to drive the swing motion. The reduction motor provides more reliable and stable swing motion without the slippage or disengagement problems associated with gear units, especially under heavy weight or prolonged use conditions.
2Ease of operation
If a swing pull handle is provided exposed to the outside for manual angle adjustment, then the ceiling fan can be adjusted to different angles, but it will spoil the external features of the fan
Solution Approach 1:
The patent removes the external swing pull handle from the fan structure and integrates the swing control function into the motor assembly. The swing motion is now driven by the reduction motor integrated into the motor housing, eliminating the need for an exposed pull handle and maintaining the fan's aesthetic appearance while preserving angle adjustment capability.
3Productivity
If multiple rotors are pivotally assembled at the outer ends of a hanging base for multi-direction wind blowing, then better effect in blowing and air current circulation is achieved, but each fan is stationary in its angle when operated requiring manual angle-fixing members
Solution Approach 1:
The patent integrates the swing function into the motor assembly, allowing a single motor unit to control the angle of multiple rotors simultaneously. The reduction motor-driven swing mechanism enables all rotors to change their blowing angles together without requiring separate angle-fixing members for each rotor, simplifying operation while maintaining multi-directional air circulation capability.
4Speed
If the swing velocity is controlled by the fan motor, then the swing motion is achieved, but the swing velocity is affected by different rotating velocities of the fan motor
Solution Approach 1:
The patent separates the swing function from the rotation function by integrating a dedicated reduction motor into the motor assembly. The reduction motor specifically controls the swing velocity through its gear reduction mechanism, independent of the fan motor's rotating velocity. This segmentation allows stable and controllable swing motion regardless of how fast the fan blades rotate.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for stable and adjustable ceiling fan operation, enhancing air circulation and ventilation by controlling swing velocity independently of the fan motor's speed, prolonging the fan's service life and improving user convenience.

AI summary
A swing structure for a ceiling fan includes a reduction motor disposed with a driving wheel having its center fixed with a connecting rod. An intermediate aluminum ring is mounted on the outer circumference of the weight center of a fan motor, having a swing spindle provided with at least one first bearing, and a threading spindle disposed at the other end set therein with a second bearing. The swing spindle has one end connected with the connecting rod. The swing velocity of the ceiling fan is controlled by the reduction motor not affected by different rotating velocities of the fan motor. A hanging tube has its lower ends respectively fixed with the swing spindle and the threading spindle and its upper end secured on a support base, enabling a ceiling fan in stalled at different angles and still able to swing smoothly.
