Ceiling Fan Surrounding Device for Air Sterilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans with integrated sterilization devices have limited air filtration and sterilization effectiveness due to the sterilization device's proximity to the ceiling fan mounting seat, restricting airflow exposure.
Innovation Solution
A ceiling fan design featuring a surrounding device with functional components, such as LED ultraviolet lamps or ozone generators, positioned around the ceiling fan blades to disinfect or sterilize air, enhancing the sterilization area by guiding airflow through a spoiler structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the sterilization device is located close to the ceiling fan mounting seat, then the device structure is compact, but the sterilization area is limited and air filtration effectiveness is reduced
Solution Approach 1:
The sterilization device is segmented into multiple independent sterilization modules (UV lamps, ozone generators, or photocatalyst modules) that are distributed around the ceiling fan blades rather than concentrated near the mounting seat. Each module can be independently positioned to maximize exposure to airflow, thereby expanding the overall sterilization area while maintaining manageable structural complexity through modular design
Solution Approach 2:
The sterilization components are arranged in a radial pattern around the ceiling fan blades, transitioning from a centralized two-dimensional layout near the mounting seat to a three-dimensional distributed configuration. This spatial redistribution allows sterilization to occur across multiple zones along the airflow path, significantly increasing the effective sterilization volume without proportionally increasing structural complexity
2Productivity
If the sterilization device is positioned near the ceiling fan mounting seat, then the installation is simple, but only part of the airflow can pass through the sterilization device
Solution Approach 1:
The airflow path is segmented into multiple zones by positioning sterilization modules at different locations around the ceiling fan blades. Each module treats a specific portion of the airflow, and collectively they provide comprehensive coverage of the entire airflow stream, thereby improving air filtration effectiveness
Solution Approach 2:
The ceiling fan structure is designed to accommodate multiple types of sterilization modules (UV lamps, ozone generators, photocatalyst modules) that can be interchanged or combined. This multi-functional design allows the same structural framework to support different sterilization technologies, maintaining installation simplicity while achieving comprehensive air treatment

Function Achieved in This Case
The solution significantly increases the sterilization area and effectiveness, achieving ozone concentrations of 0.03-0.08 ppm within four hours, surpassing the limitations of conventional designs by distributing the sterilization components around the fan blades rather than just near the motor.
