Ceiling Fan Mounting Base Assembly for Vibration-Stable Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans have complex structures leading to cumbersome assembly processes and cyclic vibrations that can damage components, resulting in poor stability of the mounting structure.
Innovation Solution
A ceiling fan mounting base with a mounting disc, fitting sleeve, and positioning units, where the fitting sleeve is hung on the mounting disc via hanging blocks and positioning units with bending edges, engaging with the hanging rod to prevent axial movement and ensure stability through protrusion and concavity interactions, eliminating the need for additional fixing units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional ceiling fan mounting structure is used, then the fan can be mounted on the ceiling, but the structure is complicated and the assembling process is cumbersome
Solution Approach 1:
The patent integrates multiple functions into the mounting base: the positioning units with bending edges simultaneously serve as positioning elements, anti-vibration elements, and assembly guides. The fitting sleeve combines hanging blocks for suspension and an accommodating space for the hanging rod, eliminating the need for separate fixing units and simplifying the overall mounting structure.
Solution Approach 2:
The positioning units are designed to automatically engage with the hanging rod through their bending edges, which flexibly snap into place without requiring additional fasteners or complex assembly steps. The structure self-assembles through its own geometric features, reducing operator workload and simplifying the assembly process.
2Reliability
If conventional mounting structure is used, then the fan can operate, but cyclic vibration damages components and detaches parts
Solution Approach 1:
The positioning units with bending edges are pre-configured to engage with the hanging rod before vibration occurs. This preliminary engagement creates a pre-loaded connection that resists cyclic vibrations from the outset, preventing component damage and detachment that would otherwise occur during fan operation.
Solution Approach 2:
The bending edges of the positioning units change their physical state under vibration loads, flexing elastically to absorb and dissipate vibrational energy. This parameter change allows the structure to adapt to dynamic loads while maintaining connection integrity, preventing the harmful effects of cyclic vibration.
3Reliability
If additional fixing units are used to prevent vibration damage, then stability improves, but the structure becomes more complex and assembly more difficult
Solution Approach 1:
The patent merges the functions of positioning units, anti-vibration elements, and connection components into a single integrated mounting base structure. The fitting sleeve and positioning units work together as a unified system, eliminating the need for separate fixing units while maintaining connection stability and reducing overall structural complexity.
