Air Compression Device Vibration Isolation and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air compression devices mounted in vehicles transmit vibrations to the vehicle frame, causing discomfort to passengers due to the direct housing of the compression mechanism, which amplifies vibrations.
Innovation Solution
The air compression device features a housing with a vibration isolator connecting it to the vehicle's underside, and a cooling device positioned outside the housing, allowing for a downsized housing that reduces vibration amplification and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the compression mechanism is housed in a large housing, then the housing can provide adequate protection and space for components, but the housing amplifies vibrations from the compression mechanism and transmits them to the vehicle
Solution Approach 1:
A vibration isolator is introduced as an intermediary component between the compression mechanism and the housing. This vibration isolator absorbs and dampens vibrations generated by the compression mechanism, preventing them from being amplified by the housing and transmitted to the vehicle body, thus resolving the contradiction between housing protection capability and vibration transmission
2Device complexity
If the cooling device is housed inside the housing, then the housing contains all components, but the housing size increases leading to greater vibration amplification
Solution Approach 1:
The air compression device is segmented into two separate parts: the compression mechanism housed in the housing, and the cooling device positioned outside the housing. This segmentation allows the housing to be downsized, reducing its vibration amplification effect, while the cooling device remains accessible outside for heat dissipation
3Object-generated harmful factors
If the housing is downsized to reduce vibration amplification, then vibration transmission to the vehicle is reduced, but space for housing components and protection capability is reduced
Solution Approach 1:
The vibration isolator serves as a mediator that enables the housing to be downsized for reduced vibration amplification while still providing adequate protection. The vibration isolator compensates for the reduced structural mass by actively damping vibrations, allowing the housing to be smaller without sacrificing protection capability
