Engineering Contradiction Analysis
1Temperature
If conventional temperature devices (heaters, sensors) are used in NMR systems, then temperature control is achieved, but electromagnetic interference exceeds magnetic tolerance limits
Solution Approach 1:
The temperature control system is segmented into multiple conductive lines arranged in winding loops, where each loop generates magnetic dipole moments that counteract the magnetic fields. This segmentation allows the system to maintain temperature control while distributing and canceling electromagnetic interference through the coordinated arrangement of multiple conductive elements.
Solution Approach 2:
The invention converts the harmful magnetic fields generated by current-conducting temperature devices into beneficial counteracting fields. By arranging conductive lines in specific winding patterns, the magnetic dipole moments generated by the same current that produces interference are directed to suppress the net magnetic field, transforming the source of harm into a solution.
2Object-affected harmful factors
If conductive lines are arranged to suppress magnetic fields, then electromagnetic interference is reduced, but device complexity increases
Solution Approach 1:
The conductive lines serve multiple functions simultaneously: they conduct current for temperature control operations and generate magnetic dipole moments for field suppression. This multi-functionality eliminates the need for separate components for temperature control and magnetic field cancellation, reducing overall device complexity despite the sophisticated arrangement of conductive lines.
Solution Approach 2:
The conductive lines are arranged in nested winding loops where inner loops are contained within outer loops. This nesting pattern allows multiple conductive elements to occupy compact space while maintaining their individual magnetic dipole moment generation, achieving field suppression without proportionally increasing device footprint or complexity.
