Fan Mount Cantilever Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan mounting techniques in electronic systems fail to effectively isolate fan vibrations from the chassis, leading to increased noise and reliability issues due to loose hardware, which can cause physical damage or short circuits.
Innovation Solution
A suspension assembly structure using a one-piece fan mount with chassis flanges forms a cantilever to isolate fan vibrations, reducing noise and eliminating loose hardware concerns through a tool-free, simple installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware (screws, nuts) is used to secure fans to the chassis, then the fans are held firmly in place, but vibrations are transferred to the chassis causing resonance and amplified noise
Solution Approach 1:
The patent introduces a fan mount as an intermediary component between the fan and chassis. This fan mount includes a body portion that receives the fan and a set of chassis interface portions that attach to the chassis, serving as a mediator that isolates vibrations while maintaining secure mounting
Solution Approach 2:
The patent extracts the harmful vibration transfer path by separating the fan mounting function from direct chassis contact. The fan mount body portion is designed to receive and isolate the fan, extracting vibrations from the direct transmission path to the chassis
2Reliability
If conventional hardware mounting is used, then fans are securely attached, but loose hardware can fall into circuitry causing physical damage or short circuits
Solution Approach 1:
The patent merges the fan mount body and fastening function into a single integrated component. The fan mount includes both the body portion that receives the fan and the chassis interface portions that provide tool-free attachment, eliminating separate loose hardware pieces
Solution Approach 2:
The fan mount is designed with self-contained attachment features where the chassis interface portions directly engage with chassis flanges without requiring separate screws or nuts. The structure provides its own fastening mechanism through the integrated body and interface portions
3Reliability
If multiple hardware components are used for fan mounting, then secure attachment is achieved, but manufacturing complexity and assembly steps increase
Solution Approach 1:
The patent combines multiple mounting functions into a single fan mount component. The body portion and chassis interface portions are integrated into one structure that provides both fan reception and chassis attachment capabilities
Solution Approach 2:
The fan mount serves multiple functions simultaneously: it receives and secures the fan, provides vibration isolation, and attaches to the chassis without requiring separate hardware components. The single structure performs mounting, isolation, and fastening functions
