Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a floating static plate is used to prevent excessive pressure, then component protection is improved, but the guide device structure becomes complicated
Solution Approach 1:
The patent integrates the guide device with the casing by directly forming the guide structure on the casing inner wall. This merging eliminates the need for separate guide components, simplifying the overall structure while maintaining the function of guiding refrigerant gas into the compression chamber effectively, even with the floating static plate present
2Temperature
If jet technology is used to introduce gas into the compression chamber, then temperature reduction is improved, but the guide device structure becomes complicated
Solution Approach 1:
The guide structure is directly formed on the casing inner wall through merging, integrating the gas introduction function into the existing casing structure. This eliminates separate guide components while maintaining effective jet technology implementation for discharge gas temperature reduction
3Ease of operation
If a separate guide device is used to introduce refrigerant gas, then gas introduction function is improved, but manufacturing cost increases
Solution Approach 1:
The guide structure is integrated directly into the casing through merging, eliminating the need for separate guide devices. This reduces the number of parts, simplifies assembly, and lowers manufacturing costs while maintaining effective refrigerant gas introduction into the compression chamber
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the compressor's simplicity and ease of installation, improves temperature monitoring accuracy, and reduces production costs by integrating the communication tube and injection hole, facilitating effective refrigerant introduction and cooling of the discharge gas.
Implementation Method 1
a communication tube (7) which defines a communication channel. The communication channel is in communication with the enthalpy increasing channel (103). One end of the communication tube (7) is at least partially located in the enthalpy increasing channel (103)... Another end of the communication tube (7) is at least partially located in the injection hole (301)
Implementation Method 2
through the jet technology, a certain amount of gas is introduced from an outlet of a condenser of a refrigeration cycle and injected into the compression chamber through a guide device. The guide device is disposed between a casing of the compressor and the fixed scroll to reduce the temperature of the discharge gas
