Engineering Contradiction Analysis
1Measurement precision
If traditional non-destructive testing techniques such as NMR or MRI are used, then detailed sample characterization is achieved, but expensive and bulky equipment is required
Solution Approach 1:
The patent extracts the essential function of electromagnetic excitation and detection from complex NMR/MRI systems. By using a simple oscillating magnetic field generated by a coil and detecting harmonic signals with a receiver, the system achieves sample characterization without requiring superconducting magnets or bulky equipment, thus removing unnecessary complexity while preserving measurement capability
Solution Approach 2:
The patent replaces expensive, complex equipment with simple, inexpensive components. The exciter uses a basic oscillating circuit with a coil, and the receiver uses standard electromagnetic detection, eliminating the need for costly superconducting magnets and complex NMR/MRI apparatus while achieving comparable sample characterization
2Reliability
If conventional electromagnetic testing methods are used, then non-destructive sample evaluation is achieved, but the equipment is expensive and not easily accessible
Solution Approach 1:
The patent replaces complex mechanical and superconducting systems with simple electromagnetic oscillation. By using an oscillating magnetic field generated through basic electromagnetic induction and detecting responses through harmonic signal analysis, the system achieves reliable non-destructive testing with inexpensive, easily manufactured components
Solution Approach 2:
The system uses the sample's own electromagnetic response characteristics to provide diagnostic information. By exciting the sample with an oscillating magnetic field and analyzing the harmonic signals generated by the sample itself, the system achieves self-characterization without requiring complex external measurement apparatus
