Ceiling Fan Hanger Assembly Dual-Axis Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of ceiling fans is challenging due to the need to account for angled ceilings, and existing solutions do not provide for easy alignment and secure suspension, leading to potential instability and increased manufacturing and assembly costs.
Innovation Solution
A ceiling fan hanger assembly featuring a mount plate with plate extensions, a downrod with downrod extensions, and a connector bracket that allows for 360-degree pivoting about two distinct axes, enabling level suspension regardless of the ceiling's orientation, while simplifying manufacturing and installation through a three-part assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional ceiling fan mounting system is used on an angled ceiling, then the ceiling fan can be installed, but the suspension becomes unstable and difficult to align level
Solution Approach 1:
The connector bracket is designed to pivot about a first pivot axis relative to the mount plate and about a second pivot axis relative to the downrod, allowing dynamic adjustment to accommodate angled ceilings while maintaining stable, level suspension. This dual-axis pivoting capability enables the system to adapt to various ceiling orientations without compromising stability or alignment.
2Manufacturing precision
If a complex mounting system with multiple adjustment mechanisms is used to handle angled ceilings, then alignment precision improves, but device complexity and manufacturing costs increase
Solution Approach 1:
The mounting system is divided into three main segments: the mount plate, the connector bracket, and the downrod. Each segment has a specific function, and they connect through pivoting joints that allow independent adjustment. This segmentation achieves precise alignment capability while keeping each component relatively simple and the overall assembly straightforward.
Solution Approach 2:
The connector bracket serves as a dynamic element that can pivot about two different axes, allowing the system to adapt to angled ceilings without requiring complex fixed adjustment mechanisms. This dynamic capability provides alignment precision while maintaining simplicity in the overall device design.
3Ease of manufacture
If a rigid fixed-angle mounting system is used, then manufacturing and assembly are simplified, but adaptability to different ceiling orientations is reduced
Solution Approach 1:
The connector bracket is designed with dual-axis pivoting capability, allowing it to adapt to various ceiling orientations while maintaining a relatively simple manufacturing process. The pivoting mechanism enables versatility without requiring complex adjustable components, thus balancing ease of manufacture with adaptability.
Solution Approach 2:
The mounting system is designed to be universal, accommodating both level and angled ceilings through the pivoting connector bracket. This multi-functionality allows a single design to serve multiple installation scenarios without requiring separate specialized components for different ceiling types.

AI summary
A ceiling fan hanger assembly includes a mount plate with a pair of plate extensions and a downrod having a pair of spaced downrod extensions. A connector bracket pivotally couples to the plate extensions to define a first pivot axis and pivotally couples to the downrod extensions to define a second pivot axis different than the first pivot axis.
