Compressor Module Segmented Support to Reduce Vibration and Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The compressor module in vehicular air-conditioning devices is heavy due to the need for high rigidity to counteract vibration, which limits weight reduction efforts.
Innovation Solution
A compressor module configuration where the supporting member is given sufficient rigidity to avoid resonance, allowing the base to indirectly support the compressor via a shock-absorbing body, reducing the need for high rigidity throughout the base and enabling weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base is made with high rigidity to avoid resonance from compressor vibration, then the reliability of ancillary equipment is improved, but the weight of the compressor module increases
Solution Approach 1:
The support structure is divided into two functional parts: a supporting member with high rigidity that directly contacts the compressor to prevent resonance, and a base with lower rigidity that supports ancillary equipment. This segmentation allows each part to have optimized properties for its specific function, avoiding the need for the entire base to be heavy and rigid.
Solution Approach 2:
High rigidity is applied locally only to the supporting member that直接接触 the compressor, while the base has lower rigidity. This local quality approach ensures that rigidity is provided exactly where needed to prevent resonance, without unnecessarily increasing the weight of the entire compressor module.
2Reliability
If the natural vibrational frequency of the base is increased to avoid resonance, then the reliability is improved, but the weight increases due to improved rigidity
Solution Approach 1:
The vibration control function is segmented from the base to a dedicated supporting member. The supporting member is designed with high rigidity and appropriate natural frequency to handle compressor vibration, while the base is freed from this requirement and can be made lighter.
Solution Approach 2:
The supporting member acts as an intermediary between the compressor and the base. It mediates the vibration control function, isolating the base from the need to have high rigidity or specific natural frequency characteristics, thereby allowing weight reduction.
3Device complexity
If the base supports the compressor directly, then the structure is simplified, but resonance occurs causing ancillary equipment to break
Solution Approach 1:
The support function is segmented into a supporting member for the compressor and a base for ancillary equipment. This segmentation prevents direct support of the compressor by the base, avoiding resonance transmission to ancillary equipment while maintaining clear functional separation.
Solution Approach 2:
The supporting member serves as an intermediary component between the compressor and the base. It absorbs and isolates vibration from the compressor, preventing resonance from being transmitted to the base and ancillary equipment, thus protecting them from damage.
