Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the signal level of processing result signals is kept constant regardless of external magnetic field intensity, then the system structure remains simple, but signal reception reliability deteriorates
Solution Approach 1:
The patent implements feedback control by detecting the external magnetic field intensity and adjusting the signal level of processing result signals accordingly. The signal level is increased when magnetic field intensity is low and decreased when magnetic field intensity is high, ensuring reliable signal reception under varying conditions. This feedback mechanism resolves the contradiction by dynamically adapting signal levels based on environmental conditions.
Solution Approach 2:
The patent transitions from a static signal level approach to a dynamic one by making signal levels adjustable based on external magnetic field intensity. The system automatically modifies signal characteristics in response to changing environmental conditions, thereby improving reception reliability without requiring complex manual intervention.
2Reliability
If the signal level is increased to ensure reception at low magnetic field intensity, then signal reception reliability improves, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts signal levels based on real-time detection of external magnetic field intensity. When magnetic field intensity is low, the signal level is increased to ensure reliable reception. When magnetic field intensity is high, the signal level is decreased to conserve power. This dynamic adaptation resolves the contradiction by optimizing the balance between reception reliability and power consumption according to environmental conditions.
Solution Approach 2:
The patent changes the signal level parameter in response to variations in external magnetic field intensity. By detecting the magnetic field strength and adjusting the signal level accordingly, the system ensures reliable communication while minimizing unnecessary power consumption. This parameter adaptation strategy effectively resolves the trade-off between reliability and energy usage.
3Reliability
If the signal level is constantly adjusted based on magnetic field intensity, then signal reception reliability improves, but the processing complexity and power usage increase
Solution Approach 1:
The patent implements dynamic signal level adjustment based on external magnetic field intensity detection. The system continuously monitors magnetic field conditions and adapts signal levels accordingly, improving reception reliability while managing power consumption through intelligent control rather than constant maximum power usage.
Solution Approach 2:
The patent changes signal level parameters based on detected magnetic field intensity. By adapting the signal level to match environmental conditions, the system achieves reliable communication without unnecessarily consuming power during high magnetic field conditions, thus resolving the contradiction between reliability and power usage.

AI summary
A noncontact communication medium includes a power generator that has a coil and generates power with application of an external magnetic field from an outside to the coil, a clock signal generator that generates a clock signal using the power, and a processor that operates using the power and executes processing on a command included in the external magnetic field. In a case where a processing result signal indicating a processing result obtained with the execution of the processing is transmitted to the outside through the external magnetic field by the coil, the processor changes a signal level of the processing result signal according to intensity of the external magnetic field.
