Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional freezing is used to store meat, then the storage temperature can be maintained, but large ice crystals form that rupture cells causing juice loss and nutritional deterioration
Solution Approach 1:
The patent introduces a magnetic field parameter to change the physical state of water during freezing. By applying a magnetic field (B≥0.3T) during the freezing process, the crystallization behavior of water is modified, resulting in smaller ice crystals that do not rupture cell structures, thereby preventing juice loss while maintaining freezing temperature
Solution Approach 2:
The patent controls the phase transition of water from liquid to solid under magnetic field influence. The magnetic field affects the hydrogen bonding network during freezing, guiding the formation of finer ice crystal structures rather than large crystals, thus preserving food quality during the phase change process
2Device complexity
If a single magnetic field generator is used, then the device structure is simple, but the magnetic field distribution is non-uniform reducing preservation effectiveness
Solution Approach 1:
The patent divides the magnetic field generation system into multiple independent generators (first and second magnetic field generators) positioned at different locations. This segmentation allows each generator to contribute to specific zones, achieving uniform overall magnetic field distribution while keeping each generator's structure relatively simple
Solution Approach 2:
The patent combines multiple magnetic field generators and a magnetic conductive plate into an integrated magnetic field device. The generators work together with the conductive plate to distribute and enhance the magnetic field, achieving uniform field distribution through the synergistic combination of multiple components
