Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna module operates at a fixed resonance point, then the antenna achieves optimal radiation efficiency at that frequency, but the performance deteriorates when a human body or metal object is close causing resonance point shift
Solution Approach 1:
The patent implements dynamic resonance point adjustment by detecting the alternating current signal waveform and automatically changing the capacitance value through a capacitance adjusting unit. This transforms the fixed resonance system into a dynamic one that can adapt to environmental changes, resolving the contradiction between maintaining optimal radiation efficiency and adapting to resonance point shifts caused by human body or metal objects.
Solution Approach 2:
The monitoring module detects the alternating current signal waveform and provides feedback to the determining module, which then generates an adjusting voltage value to modify the capacitance. This closed-loop feedback mechanism enables the antenna system to automatically compensate for resonance point shifts, maintaining reliable performance despite changes in the electromagnetic environment.
2Ease of manufacture
If the capacitance value is fixed, then the antenna module has simple structure and easy manufacture, but the resonance point cannot be adjusted when environmental conditions change
Solution Approach 1:
The patent changes the capacitance parameter dynamically by applying an adjusting voltage value generated from the detected signal waveform. This allows the antenna module to maintain a simple fixed structure during manufacturing while enabling parameter adjustment during operation, resolving the contradiction between manufacturing simplicity and operational adaptability.
3Reliability
If the antenna module uses automatic resonance adjustment, then the antenna maintains optimal performance under varying conditions, but the device complexity increases due to additional monitoring and capacitance adjusting components
Solution Approach 1:
The antenna module performs self-adjustment by automatically detecting its own signal waveform and generating the appropriate capacitance adjustment without external intervention. The monitoring module monitors the antenna's own performance, and the capacitance adjusting unit self-corrects the resonance point, reducing the need for complex external control systems while maintaining reliable performance.
