Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If frequency debugging is performed by traditional methods, then the operating frequency can be adjusted, but the communication quality and distance deteriorate due to frequency deviation from target range
Solution Approach 1:
The patent implements a feedback mechanism where the operating frequency is continuously monitored and compared against the target frequency range. Based on the detected deviation, the system automatically adjusts the capacitance of the variable capacitor to bring the frequency back within the acceptable range, thereby maintaining communication quality while achieving precise frequency control.
Solution Approach 2:
The patent changes the electrical parameter (capacitance) of the variable capacitor to adjust the operating frequency of the electronic device. By varying the capacitance value, the resonant frequency of the LC circuit is shifted to align with the target frequency range, thus improving both frequency accuracy and communication reliability.
2Measurement precision
If frequency debugging is performed by traditional methods, then the operating frequency can be adjusted, but the debugging process becomes complex and time-consuming
Solution Approach 1:
The patent enables the system to perform frequency debugging automatically without requiring manual intervention. The frequency tester detects the operating frequency, compares it with the target range, and the controller automatically adjusts the variable capacitor's capacitance accordingly. This self-service capability significantly reduces debugging time while maintaining high frequency accuracy.
Solution Approach 2:
The patent incorporates a frequency tester and control system that are pre-configured with the target frequency range. Before actual operation, the system is prepared to detect and adjust frequency deviations, eliminating the need for time-consuming manual frequency tuning and circuit modifications during the debugging phase.
3Measurement precision
If frequency debugging is performed by traditional methods, then the operating frequency can be adjusted, but circuit modifications become necessary and complex
Solution Approach 1:
The patent introduces a variable capacitor as an intermediary component between the existing circuit and the frequency adjustment mechanism. This intermediary element allows for frequency tuning without requiring modifications to the core circuit architecture, thereby maintaining circuit simplicity while achieving precise frequency control through capacitance variation.
