Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an enthalpy increasing system with intermediate cooling structure is used, then ultra-low temperature rapid heating capability is improved, but system complexity and pipeline arrangements increase
Solution Approach 1:
The patent integrates the flash device structure into the compressor body, merging two separate components (compressor and flash device) into a single integrated unit. This eliminates the need for additional intermediate cooling structures and reduces pipeline arrangements, directly resolving the technical contradiction by maintaining ultra-low temperature rapid heating capability while significantly simplifying system complexity
2Temperature
If an enthalpy increasing system with additional intermediate cooling structure is used, then ultra-low temperature rapid heating capability is improved, but system weight increases
Solution Approach 1:
By integrating the flash device into the compressor body, the patent eliminates the weight of additional intermediate cooling structures and pipelines. The merged structure uses the existing compressor housing and internal passages, thereby achieving ultra-low temperature rapid heating without increasing system weight
3Reliability
If conventional scroll compressors are used, then energy conservation and reliability are maintained, but ultra-low temperature rapid heating requirement is not met
Solution Approach 1:
The patent combines a flash device with the scroll compressor to create an integrated unit that maintains the reliability and energy conservation characteristics of conventional scroll compressors while adding ultra-low temperature rapid heating capability through the integrated flash device functionality
Solution Approach 2:
The integrated compressor- flash device unit performs multiple functions: compression of refrigerant gas and flash evaporation of refrigerant liquid. This multi-functionality allows the system to maintain conventional compressor reliability while achieving ultra-low temperature rapid heating performance
4Use of energy by moving object
If excessive pipeline arrangements are used in the air conditioning system, then enthalpy increasing function is achieved, but system reliability and endurance are reduced
Solution Approach 1:
By integrating the flash device into the compressor body, the patent eliminates excessive pipeline arrangements and reduces the number of connection points. This integrated structure achieves the enthalpy increasing function while improving system reliability by reducing potential failure points and enhancing overall system endurance
