Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single inductor is used to sense electromagnetic signals, then the device structure is simple, but the ability to distinguish signals based on specific frequencies is poor
Solution Approach 1:
The receiving circuit is divided into multiple independent receiving circuits (first receiving circuit, second receiving circuit, third receiving circuit), each with its own inductor and processing path. This segmentation allows each circuit to specialize in detecting specific frequency ranges or signal characteristics, thereby improving frequency identification accuracy while maintaining relatively simple individual circuit structures.
Solution Approach 2:
The patent introduces a light-emitting device as a fourth dimension of detection. By converting electrical signals into optical signals through the light-emitting device, the system creates a new detection dimension that enhances the ability to distinguish between different frequency signals, enabling more precise frequency identification beyond what traditional electrical measurement alone could achieve.
2Power
If inductance values of first inductors are increased stage by stage, then the amplification capability is improved, but the device complexity increases
Solution Approach 1:
The inductance values of the first inductors are configured to increase stage by stage through the receiving sub-circuits, creating a dynamic amplification structure. This progressive increase in inductance values allows each stage to provide appropriate amplification for its specific frequency range, improving overall signal detection capability while organizing the complexity in a systematic, manageable progression rather than a uniform structure.
3Measurement precision
If the light-emitting device is used to indicate signal differences, then the measurement precision is improved, but the energy consumption increases
Solution Approach 1:
The light-emitting device serves dual purposes: it acts as both a signal processing component and a detection indicator. The same circuitry that processes the electromagnetic signals also drives the light-emitting device to visually indicate signal presence and characteristics, eliminating the need for separate detection and indication systems, thereby reducing overall energy consumption while maintaining high measurement precision.
