Modular Fan Protective Shell for Low-Cost Ceiling Fan Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling fan designs require replacement of the entire protective shell when damaged, which is costly and inefficient.
Innovation Solution
A modular fan protective shell structure with detachable protective units and appropriate spacing, allowing individual replacement of damaged parts without compromising protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an integrated protective shell is used around the motor, then the motor protection is improved, but the replacement cost increases when damaged
Solution Approach 1:
The protective shell is divided into multiple detachable protective units (first protective unit, second protective unit, third protective unit) that can be individually replaced. Each unit is connected to the connecting assembly through detachable connections (screws, snap-fit connections, or magnetic connections), allowing only the damaged unit to be replaced rather than the entire shell, thus reducing replacement costs while maintaining motor protection.
2Reliability
If an integrated protective shell is used around the motor, then the motor protection is improved, but the device complexity increases
Solution Approach 1:
The protective shell is segmented into multiple independent units that attach to a central connecting assembly. This segmentation maintains protection effectiveness while simplifying the overall structure through modular design, making each component simpler and easier to manufacture individually.
Solution Approach 2:
The connecting assembly serves multiple functions: it connects all protective units, provides mounting positions for lighting modules and fans, and enables detachable connections for easy replacement. This multi-functionality reduces the need for separate components, thereby reducing device complexity.
3Ease of manufacture
If protective units are spaced apart from each other, then the replacement cost is reduced, but the protection coverage may be compromised
Solution Approach 1:
The protective shell is divided into multiple protective units with appropriate spacing between them. This segmentation allows individual replacement of damaged units, reducing costs. The spacing is designed to maintain adequate motor protection while enabling access for replacement operations.
Data Source
AI summary
The present disclosure discloses a fan protective shell structure, including a connecting assembly and at least three protective units, in which the protective units are detachably connected to the connecting assembly, and the protective units are spaced apart from each other. The disclosure also discloses a ceiling fan using the fan protective shell structure, including a motor, with the fan protective shell structure surrounding the motor, and the lower end of the fan body further includes a light. While providing protection for the motor, this design allows for the individual replacement of damaged parts, effectively reducing costs.
