Elastic Fan Frame Vibration Attenuation via Intermediary Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fan structures generate noise due to vibration, which is transmitted through the fan's mechanical movement and resonance with the casing, causing disturbance and potentially leading to equipment failure, and existing vibration attenuation methods are cumbersome and costly.
Innovation Solution
A fan device with an elastic frame that covers the fan entirely, featuring openings for airflow and a buffer layer between the fan and casing to isolate vibration, allowing for easy assembly and disassembly, and optionally incorporating magnetic fixation and colorful lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional rigid fan structure is used, then structural strength is maintained, but vibration noise is transmitted to the casing
Solution Approach 1:
The patent introduces an elastic frame as an intermediary component between the fan and the casing. This elastic frame serves as a mediator that transmits the fan's operational forces while filtering out harmful vibrations, preventing noise transmission to the casing while still providing structural support for the fan assembly.
Solution Approach 2:
The patent changes the physical parameter of the frame from rigid to elastic. By using an elastic material for the frame, the system transforms the mechanical properties to allow vibration absorption and noise reduction while maintaining sufficient structural strength to support the fan and enable mounting to the casing.
2Object-affected harmful factors
If spacers are used to attenuate vibration, then noise reduction is achieved, but assembly complexity increases and small pieces may be lost
Solution Approach 1:
The patent merges the vibration attenuation function with the frame structure itself. Instead of using separate spacers or buffers, the elastic frame is designed as an integrated component that provides both structural support and vibration isolation, eliminating the need for additional separate parts and simplifying the assembly process.
Solution Approach 2:
The elastic frame performs multiple functions simultaneously: it provides structural support for the fan, enables mounting to the casing, and attenuates vibration noise. This multi-functional design replaces multiple separate components with a single integrated solution that simplifies the overall assembly.
3Object-affected harmful factors
If plastic riveting is used for buffering vibration, then noise attenuation is achieved, but cost and assembling difficulty increase
Solution Approach 1:
The elastic frame is designed as a simple, cost-effective component that can be easily manufactured and replaced if needed. The use of elastic material allows for simple molding processes and eliminates the need for complex assembly operations, making the overall manufacturing process more economical and easier to execute.

AI summary
A fan device with a vibration attenuating structure is disclosed. The fan device with a vibration attenuating structure comprises a fan and a frame covering the fan. The frame entirely covers the fan, and two opposing sides of the frame have an opening thereon. The openings are corresponding to blades of the fan to form the flowing path of the air. As above-mentioned, the frame performs as a buffering member for attenuating the vibration of the fan so as to prevent the noise generated by the vibration.
