Solution Overview
Problem
Conventional compressors in refrigeration cycles face challenges in reducing noise across a wide frequency band without the need for additional components.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the shape of the conventional muffler and the number of discharge holes are changed or a resonator is applied to the inside of a cylinder, then noise reduction is improved, but device complexity increases
Solution Approach 1:
The patent combines the noise reduction function with the existing flange structure by forming noise reduction units directly on the flange. This integration merges the structural support function of the flange with the noise reduction function, eliminating the need for separate resonators or modified muffler designs, thus reducing device complexity while maintaining noise reduction effectiveness
Solution Approach 2:
The flange is designed to serve multiple functions: structural support for the compressor components and noise reduction through the integrated noise reduction units. This multi-functionality allows the same component to address both mechanical support and acoustic noise reduction, avoiding additional components and simplifying the overall device structure
2Object-affected harmful factors
If additional components are added to reduce noise, then noise reduction is improved, but device complexity increases
Solution Approach 1:
The noise reduction units are formed as integral parts of the flange structure through recesses or cavities. This merging eliminates the need for separate resonators or additional noise reduction components, achieving noise reduction functionality without increasing device complexity or requiring extra parts
Solution Approach 2:
The flange structure itself provides noise reduction functionality through its own geometric features (recesses and cavities) rather than requiring external noise reduction components. The existing structural element serves its primary support function while simultaneously providing acoustic noise reduction, making the system self-sufficient
