Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cooling target is directly brought into tight contact with the cooling portion of a refrigerating machine, then cooling efficiency is improved, but vibration is transmitted to the cooling target
Solution Approach 1:
A flexible pipe filled with fluidized refrigerant serves as an intermediary between the cooling portion and the cooling target. This intermediary allows heat transfer while isolating the cooling target from vibration generated by the refrigerating machine's compressor and pump operations.
Solution Approach 2:
The patent replaces direct mechanical contact (tight contact between cooling portion and target) with a fluid-based heat transfer system. The fluidized refrigerant in the flexible pipe transfers heat without transmitting mechanical vibrations, substituting a mechanical coupling with a fluid coupling.
2Object-affected harmful factors
If the refrigerating machine is installed at a location away from the cooling target to reduce vibration, then vibration transmission is reduced, but the installation distance must be large and heat transfer efficiency decreases
Solution Approach 1:
The flexible pipe filled with fluidized refrigerant acts as an intermediary that bridges the gap between the refrigerating machine and the cooling target. This allows the machine to be positioned away from the target for vibration reduction while maintaining effective heat transfer through the fluid medium in the pipe.
Solution Approach 2:
The patent utilizes a hydraulic system (fluidized refrigerant in a flexible pipe) to transfer thermal energy over a distance. The fluid medium enables heat transfer without requiring direct mechanical connection, allowing the refrigerating machine to be positioned away from the cooling target while maintaining heat transfer efficiency.
3Object-affected harmful factors
If a heat-insulated long pipe is used to supply refrigerant under pressure in the atmosphere, then the refrigerating machine can be positioned away from the cooling target, but external heat influences the pipe and refrigerant temperature rises
Solution Approach 1:
The patent employs a vacuum environment as an inert atmosphere that isolates the refrigerant pipe from external heat sources. By operating in vacuum, the system eliminates convective and conductive heat transfer from the surrounding atmosphere, preventing refrigerant temperature rise even over long distances.
Solution Approach 2:
The flexible pipe filled with fluidized refrigerant creates a closed hydraulic system that maintains thermal isolation. The fluid medium inside the pipe transfers heat efficiently between the cooling portion and target while the flexible pipe structure provides thermal insulation, preventing external heat influence on the refrigerant temperature.
4Object-affected harmful factors
If a circulating pump is used to supply refrigerant under pressure, then the refrigerating machine can be positioned away from the cooling target, but heat generated by the pump motor increases the refrigerant temperature
Solution Approach 1:
The patent extracts the refrigerant circulation function from a motor-driven pump and replaces it with a passive gravity-based circulation system. By eliminating the motor, the source of harmful heat generation is removed, while refrigerant circulation is maintained through natural convection and gravity forces in the flexible pipe system.
Solution Approach 2:
The refrigerant circulation system operates autonomously without external power input. The fluidized refrigerant circulates through the flexible pipe using natural convection currents driven by temperature differences and gravity, eliminating the need for a motor-driven pump and the associated heat generation.
