Engineering Contradiction Analysis
1Illumination intensity
If transmission power is increased to extend transmission range, then signal coverage is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic transmission power adjustment by introducing a counter-controlled variable gain amplifier that continuously adjusts amplification levels based on transmission requirements. The counter generates sequential control signals that dynamically modify the amplifier gain, enabling the system to adapt transmission power to actual needs rather than operating at fixed high power levels
Solution Approach 2:
The patent changes the amplification parameter of the power amplifier in discrete steps controlled by a counter. The counter value directly controls the gain level, allowing systematic adjustment of transmission power from minimum to maximum and vice versa, optimizing the balance between signal coverage and power consumption based on real-time conditions
2Productivity
If transmission power is rapidly adjusted to respond to changing conditions, then transmission performance is improved, but control complexity increases
Solution Approach 1:
The patent segments the amplification adjustment into discrete controlled steps using a counter with specific bit width. Instead of continuous analog control, the system divides the gain range into quantized levels corresponding to counter values, simplifying the control mechanism while maintaining effective transmission performance through stepwise power adjustment
Solution Approach 2:
The patent implements a feedback control mechanism where the counter value is continuously compared with a target value, and the amplification is adjusted based on the comparison result. This closed-loop control enables automatic adaptation to changing transmission conditions while maintaining manageable control complexity through systematic feedback processing
