Modular Fan Mount Restrictor for Sway Control on Uneven Ceilings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan mounting systems do not effectively address the issue of sway and oscillation, particularly in non-level ceilings, and lack modular components for easy retrofitting and adjustment.
Innovation Solution
A modular restrictor system for fan mounts, comprising interconnected portions that engage with a stanchion and a partially spherical ball, providing frictional resistance to limit fan movement and sway, while allowing rotational freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional fan mounting system is used, then the fan can be installed, but it experiences sway and oscillation particularly on non-level ceilings
Solution Approach 1:
The restrictor is divided into multiple segments that can be independently adjusted and positioned around the stanchion, allowing each segment to provide individual frictional contact points that collectively stabilize the fan while accommodating non-level surfaces
Solution Approach 2:
The restrictor utilizes adjustable friction parameters through its contact surfaces with the stanchion and ball, allowing the system to optimize the balance between allowing necessary rotational movement and preventing harmful sway and oscillation
2Ease of manufacture
If a fixed restrictor system is used, then fan movement is limited, but it cannot be easily adjusted or retrofitted
Solution Approach 1:
The restrictor's segmented design allows individual sections to be independently installed, adjusted, or replaced without affecting the entire mounting system, enabling easy retrofitting and maintenance while managing complexity through modular components
Solution Approach 2:
The restrictor incorporates dynamic adjustment capabilities that allow the system to adapt to different installation conditions and fan types, providing flexibility for retrofitted applications while maintaining stable operation through adjustable friction characteristics
3Ease of operation
If a restrictor system is added to limit fan movement, then sway is reduced, but the fan loses rotational freedom
Solution Approach 1:
The restrictor applies frictional resistance locally at specific contact points with the stanchion and ball, providing sway limitation in horizontal directions while maintaining rotational freedom in the vertical axis through strategically positioned contact surfaces
Solution Approach 2:
The system adjusts the friction parameter at the restrictor-stanchion interface to optimize the balance between limiting harmful sway movements and allowing necessary rotational adjustments, particularly important for accommodating non-level ceiling installations

AI summary
A dynamic fan mount for supporting the fan has a first part movable relative to a second part. A modular restrictor restricts lateral movement or swaying of the fan. In one embodiment, the modular restrictor is formed of two portions, which may be interconnected by a fastener, and one of which includes a channel in communication with a central passage.
