Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed intensity of electromagnetic field or electric field is used for cooling, then the cooling apparatus can operate with simple control, but it cannot efficiently achieve subcooling state for diverse types of objects and consumes excessive energy
Solution Approach 1:
The patent applies dynamics by making the field intensity variable rather than fixed. The controller dynamically adjusts the intensity of the electromagnetic field or electric field based on real-time temperature feedback from the cooling target object, enabling efficient subcooling for diverse object types while optimizing energy consumption.
Solution Approach 2:
The patent implements feedback control by using a temperature sensor to monitor the cooling target object's temperature and feeding this information back to the controller. The controller then adjusts the field intensity accordingly, creating a closed-loop system that achieves adaptability while minimizing energy waste.
2Reliability
If a comparatively large value with safety margin is employed for field intensity, then the subcooling state can be reliably achieved for all object types, but energy efficiency deteriorates
Solution Approach 1:
The feedback control mechanism monitors the actual temperature of the cooling target object and adjusts the field intensity in real-time. This eliminates the need for excessive safety margins while maintaining reliable subcooling achievement, as the system responds to actual conditions rather than relying on conservative fixed values.
Solution Approach 2:
The patent changes the field intensity parameter dynamically based on temperature measurements. Instead of using a fixed high value with safety margin, the system adjusts the parameter (field intensity) to match the actual cooling requirements, maintaining reliability while reducing energy consumption.
3Use of energy by moving object
If different appropriate values are set for different types of objects in advance, then energy efficiency improves for known objects, but the system cannot handle unspecified or variable object types
Solution Approach 1:
The feedback control system eliminates the need for pre-setting values for different object types. By continuously monitoring temperature and adjusting field intensity in real-time, the system adapts to any object type automatically, maintaining energy efficiency while achieving universal applicability.
Solution Approach 2:
The system performs self-adjustment by using its own temperature measurements to determine the appropriate field intensity. This self-service capability allows the system to handle any object type without requiring external programming or pre-configuration, combining energy efficiency with universal adaptability.
