Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal amplification is increased to improve signal quality, then signal quality is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic control of the sensitive amplifier by introducing a control signal generation circuit that dynamically adjusts the amplifier's operation based on signal conditions. The power consumption control circuit receives power consumption control signals and generates corresponding control signals to enable the amplifier to switch between different operating modes (high gain/high power and low gain/low power), resolving the contradiction between signal quality and power consumption through dynamic adaptation rather than static operation
Solution Approach 2:
The patent changes the operating parameters of the sensitive amplifier by controlling its gain and power consumption levels through externally generated control signals. By adjusting these parameters based on signal requirements, the system can optimize the balance between signal quality enhancement and power consumption reduction, allowing the amplifier to operate at different performance levels as needed
2Speed
If amplification circuit operates continuously to maintain signal readiness, then signal responsiveness is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic or on-demand operation of the amplification circuit through control signals that activate the amplifier only when signal amplification is required. The power consumption control circuit enables the amplifier to enter low-power states between active periods, maintaining signal responsiveness when needed while reducing power consumption during idle periods through controlled activation and deactivation cycles
