Fan Mount Bracket with Annular Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The vibration caused by fan motors in electronic products is transmitted to other components through traditional mount brackets, leading to unfavorable effects on these components.
Innovation Solution
A mount bracket design incorporating a button plate, a frame, and vibration-absorbing components or a vibration-absorbing sleeve, which are strategically placed between the button plate and the frame to absorb and dissipate the motor-induced vibrations, preventing their transmission to other electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-piece supporting piece is used to mount the fan, then the installation is simple and the structure is compact, but the vibration caused by the fan motor is transmitted to other electronic components
Solution Approach 1:
The single-piece supporting piece is divided into multiple separate components: a button plate for mounting the motor, a frame surrounding the button plate, and multiple vibration-absorbing components positioned between them. This segmentation allows the vibration-absorbing components to be inserted into gaps between the button plate and frame, effectively blocking vibration transmission paths while maintaining structural support functionality.
Solution Approach 2:
Vibration-absorbing components are introduced as intermediary elements between the button plate (which directly supports the motor) and the frame (which connects to the electronic product chassis). These intermediaries absorb and dissipate motor vibrations through elastic deformation, preventing direct transmission to other electronic components while still allowing the mount bracket to perform its supporting function.
2Object-affected harmful factors
If vibration-absorbing components are added to the mount bracket, then the vibration transmission is reduced, but the device complexity increases
Solution Approach 1:
Vibration-absorbing components are strategically positioned only at critical locations where vibration transmission occurs most significantly - specifically in the gaps between the button plate and frame. This localized approach targets the most problematic vibration paths without adding unnecessary components throughout the entire structure, thus reducing complexity compared to a complete redesign.
Solution Approach 2:
The vibration-absorbing components are nested within the existing mount bracket structure, specifically positioned in the gaps between the button plate and frame. This nesting approach allows the vibration-absorbing elements to be integrated into the existing design without requiring a complete structural overhaul, minimizing the increase in device complexity.
