Floating-Flange Vibration Mount With Orthogonal Spring Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounts for mobile devices and other objects fail to effectively dampen vibrations when attached to surfaces or vehicles that produce vibrations, leading to discomfort and potential damage to the attached devices.
Innovation Solution
A mount design featuring a floating unit with a floating flange and a base unit with spring mounts and compression springs, allowing the floating unit and base unit to move relative to each other, thereby reducing vibration transmission. The mount also includes vibration dampening grease to enhance vibration reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid mount structure is used to securely hold the device, then the device is firmly attached to the surface, but vibrations from the surface are transmitted to the device
Solution Approach 1:
The mount is divided into multiple independent spring elements arranged in parallel, each capable of absorbing vibrations independently. The floating flange is segmented into multiple fingers that can move relative to each other, enhancing vibration isolation while maintaining attachment strength
Solution Approach 2:
Spring elements are introduced as intermediary components between the base housing and the floating flange. These springs act as mediators that decouple the rigid connection, allowing relative movement and vibration absorption while maintaining the structural connection
2Object-affected harmful factors
If spring elements are added to dampen vibrations, then vibration transmission is reduced, but the device complexity increases
Solution Approach 1:
The spring elements serve multiple functions simultaneously: they provide mechanical support to hold the floating flange, absorb vibrations in multiple directions, and allow relative movement between the base and floating unit. This multi-functionality reduces the need for additional separate components
Solution Approach 2:
Multiple spring elements are combined in a compact arrangement within the base housing, with fingers of the floating flange integrated directly into the spring mounting structure. This merging of components achieves effective vibration dampening while minimizing the overall structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mount effectively reduces vibration transmission between the base unit and the floating unit, providing a stable and comfortable environment for attached devices, even in vibrating conditions.
Implementation Method 1
a plurality of first springs disposed in the base housing and oriented parallel to a first floating axis, wherein each of the first springs is mounted on at least one of the spring mounts and receives a portion of one of the fingers of the floating flange
Implementation Method 2
at least three first compression springs disposed in the base housing and oriented parallel to a first floating axis; at least three second compression springs oriented orthogonally to the first compression springs
Implementation Method 3
The mount also includes vibration dampening grease to enhance vibration reduction
