Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If quick freezing or supercooling is used to increase freezing speed, then freezing storage quality is improved, but energy consumption increases and refrigerating capacity requirements increase
Solution Approach 1:
The patent introduces magnetic field parameters (strength, direction, duration) as a new control variable for the freezing process. By adjusting magnetic field parameters rather than solely relying on temperature and time parameters, the system achieves improved freezing quality without proportionally increasing energy consumption. The magnetic field acts as an auxiliary parameter that enhances the freezing process efficiency.
Solution Approach 2:
The magnetic field serves as an intermediary substance that mediates between the refrigeration system and the food being frozen. Instead of directly increasing refrigeration capacity or using energy-intensive quick freezing methods, the magnetic field acts as a mediator to influence ice crystal formation, thereby improving freezing quality while consuming less energy.
2Manufacturing precision
If magnetic field is applied to assist freezing, then freezing quality is improved, but device complexity increases
Solution Approach 1:
The magnetic field application system is segmented into independent electromagnetic coils that can be individually controlled. Rather than using a single complex magnetic field source, the system divides the magnetic field generation into multiple simpler coil units, each capable of being activated or deactivated independently based on detection signals, thereby reducing overall system complexity while maintaining effectiveness.
Solution Approach 2:
The magnetic field application is made dynamic and adaptive rather than static and fixed. The system continuously monitors food state through detection devices and adjusts magnetic field parameters (strength, duration, which coils are active) in real-time. This dynamic control allows the system to achieve optimal freezing quality with minimal magnetic field application, reducing the need for overly complex permanent magnetic field structures.
3Object-affected harmful factors
If electromagnetic coils are arranged outside the storage box, then interference with other components is reduced, but magnetic field effectiveness may be compromised
Solution Approach 1:
The magnetic frame made of magnetic material serves as an intermediary that channels and concentrates the magnetic field generated by the externally arranged electromagnetic coils. The magnetic frame acts as a magnetic conductor that guides the magnetic flux through the storage box, ensuring that even though the coils are positioned outside, the magnetic field remains effective within the storage space while minimizing interference with other refrigerator components.
Solution Approach 2:
The magnetic field distribution is optimized to be locally concentrated where needed (within the storage box) rather than uniformly distributed throughout the entire refrigerator. The magnetic frame creates localized magnetic field intensity at the storage box region, ensuring effectiveness where required while allowing the electromagnetic coils to be positioned externally to avoid interfering with other components.
