Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the accumulator is installed externally, then the assembly process becomes complex and the number of connecting portions increases, but the compressor size increases and design flexibility is reduced
Solution Approach 1:
The accumulator is integrated within the compressor shell, merging two previously separate components (compressor and accumulator) into a unified structure. This eliminates the need for external installation and connecting portions, thereby simplifying the assembly process while reducing the overall compressor size and improving design flexibility.
2Device complexity
If the accumulator is installed externally, then the connecting portions increase, but refrigerant leakage risk increases
Solution Approach 1:
By integrating the accumulator within the compressor shell, the invention eliminates external connecting portions and joints. This unified structure removes potential leakage points at connection interfaces, thereby improving system reliability and preventing refrigerant leakage while reducing structural complexity.
3Ease of manufacture
If the accumulator is installed externally, then the assembly process becomes complex, but vibration noise increases
Solution Approach 1:
The integration of the accumulator within the compressor shell creates a unified, compact structure that reduces the number of separate components and their associated mounting connections. This consolidated design minimizes vibration sources and noise transmission paths, thereby decreasing vibration noise while simplifying the assembly process.
4Device complexity
If the accumulator is installed externally, then the connecting portions increase, but design flexibility is reduced
Solution Approach 1:
By consolidating the accumulator within the compressor shell, the invention creates a more compact and integrated unit. This unified structure reduces the number of external connecting portions and simplifies the overall system architecture, thereby enhancing design flexibility and adaptability for various installation scenarios.

AI summary
A compressor is provided having an accumulator that may form an accumulating chamber at an internal space of a shell, thereby reducing a size of the compressor, and simplifying an assembly process. A stationary shaft having a refrigerant suction passage may be directly connected to the accumulator to prevent leakage of refrigerant. Further, a center of gravity of the accumulator may correspond to a center of gravity of the compressor to reduce vibration noise of the compressor caused by the accumulator. Furthermore, an oil collecting plate may be installed at an upper end of an upper bearing to supply oil between a vein and vein slot, thereby preventing compression loss. Also, an installation area of the compressor including the accumulator may be minimized to enhance design flexibility of an outdoor device employing the compressor and minimize interference with other components, thereby facilitating installation of the outdoor device.
