Compressor Module Base Segmentation to Reduce Weight and Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The compressor module in vehicular air-conditioning devices vibrates during operation, leading to resonance issues that can cause ancillary equipment to break, making it difficult to reduce the weight of the compressor module and the entire air-conditioning device while maintaining sufficient rigidity to avoid vibration propagation.
Innovation Solution
A compressor module configuration that includes a compressor, a supporting member, a shock-absorbing body, and ancillary equipment supported by a base fixed to the casing, where the supporting member is designed to avoid resonance by imparting sufficient rigidity, allowing the base to be less rigid and reducing the overall weight of the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base is made with high rigidity to avoid resonance and support the compressor, then vibration suppression is improved, but the weight of the compressor module increases
Solution Approach 1:
The base is divided into a first base portion supporting the compressor and a second base portion supporting ancillary equipment. The first base portion is designed with higher rigidity to handle compressor vibrations, while the second base portion can be lighter since it only supports static ancillary equipment. This segmentation allows weight reduction in non-critical areas while maintaining vibration suppression where needed.
Solution Approach 2:
Different portions of the base are given different rigidity characteristics tailored to their specific functions. The first base portion near the compressor has optimized rigidity for vibration suppression, while the second base portion has reduced rigidity requirements. This local differentiation eliminates the need for the entire base to be heavy, reducing overall weight while maintaining reliability.
2Weight of moving object
If the base is made lighter to reduce overall weight, then weight reduction is achieved, but rigidity is insufficient leading to resonance and potential equipment failure
Solution Approach 1:
The base structure is segmented into functional zones with different rigidity requirements. The first base portion maintaining contact with the compressor retains sufficient rigidity for vibration suppression, while the second base portion supporting only ancillary equipment can be significantly lighter. This allows overall weight reduction without compromising the strength needed for vibration handling.
Solution Approach 2:
The base exhibits non-uniform rigidity distribution optimized for each location's requirements. Critical areas near the compressor maintain high rigidity, while non-critical areas are lightweighted. This local quality approach achieves weight reduction while preserving necessary strength characteristics.
3Reliability
If vibration-reducing rubber body is used to suppress vibration propagation, then vibration reduction is improved, but the base still needs high rigidity to avoid resonance
Solution Approach 1:
The base is segmented so that the first base portion near the compressor can utilize vibration-reducing rubber bodies for vibration isolation, while the second base portion doesn't require such measures since it only supports static ancillary equipment. This segmentation allows weight reduction in the second portion while maintaining vibration reduction performance where needed.
Solution Approach 2:
Vibration-reducing rubber bodies are introduced as intermediary elements between the compressor and the first base portion. These rubber bodies act as vibration isolators, reducing the transmission of vibrations to the base structure. This allows the base to be lighter overall while still achieving effective vibration reduction through the intermediary damping elements.
