Vibration isolation mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration isolation methods for compressors, such as using o-rings, poorly isolate the housing from compressor vibrations and complicate the insertion process due to high friction.
Innovation Solution
A vibration isolation mount comprising an elastomeric sleeve with tapered studs or axial ribs and a lip seal, which deforms to isolate radial vibrations and creates an annular seal, allowing easier insertion and improved vibration isolation while maintaining a seal between the compressor and housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If o-rings are used to mount the compressor within the housing, then a seal is created between the compressor and housing, but the housing is poorly isolated from compressor vibrations due to large contact area
Solution Approach 1:
The mount is segmented into multiple functional elements: tapered studs or axial ribs for vibration isolation and a lip seal for sealing. This segmentation allows each element to perform its specific function optimally - the studs/ribs provide radial compliance for vibration isolation while the lip seal maintains the seal, resolving the contradiction between vibration isolation and seal quality
Solution Approach 2:
Different parts of the mount have different local properties - the studs or ribs are designed with radial compliance for vibration isolation, while the lip seal is designed with appropriate sealing properties. This local differentiation allows the mount to simultaneously achieve good vibration isolation and reliable sealing without the trade-off present in uniform o-ring designs
2Ease of operation
If o-rings are used to seal between the compressor and housing, then a seal is provided, but insertion is difficult due to high friction between the o-rings and housing
Solution Approach 1:
The sealing function is separated from the mounting structure. The lip seal is a distinct element that can be easily inserted along with the compressor, while the tapered studs or axial ribs provide a low-friction interface during insertion. This segmentation resolves the contradiction by eliminating the high friction problem of traditional o-rings while maintaining seal quality
Solution Approach 2:
The lip seal acts as an intermediary element that provides sealing without creating high friction during insertion. Unlike traditional o-rings that must deform significantly to seal, the lip seal design allows for easier insertion while maintaining reliable sealing between the compressor and housing
3Reliability
If the seal contacts the housing over a large area, then a good seal is formed, but radial vibration is transmitted more effectively to the housing
Solution Approach 1:
The mount segments the sealing function from the vibration isolation function. The lip seal provides the seal between compressor and housing, while the tapered studs or axial ribs are specifically designed for vibration isolation with radial compliance. This segmentation allows the seal to contact the housing over a large area for good sealing while the vibration isolation elements manage the vibration transmission, resolving the contradiction
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 solution effectively reduces vibration transmission to the housing and simplifies the insertion process by utilizing a smaller contact area with the studs or ribs, while the lip seal ensures a consistent seal with high compliance, minimizing radial vibration transmission.
Implementation Method 1
the elastomeric material and comprising a sleeve, a plurality of tapered studs or axial ribs spaced around the sleeve... the studs or ribs deform to isolate the housing from radial vibration of the compressor
Implementation Method 2
the studs or ribs deform to isolate the housing from radial vibration of the compressor... the radial compliance of the seal may be greater than that of the studs or ribs
Implementation Method 3
the lip seal creates an annular seal between the housing and the compressor... the lip seal is intended only to create a seal between the compressor and the housing

AI summary
A vibration isolation mount for a compressor that is formed of an elastomeric material and includes a sleeve, tapered studs or axial ribs spaced around the sleeve, and a lip seal extending around the sleeve. The mount is intended to be located between a compressor and a housing. The studs or ribs then deform to isolate the housing from radial vibration of the compressor, and the lip seal creates an annular seal between the housing and the compressor.
