Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the semiconductor device operates in a mode where output signal levels are dynamically determined based on input signals, then the operational flexibility and signal processing capability are improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic operational modes where the amplification circuit can switch between different operating states (normal mode and power-saving mode) based on control signals. In normal mode, the circuit dynamically processes input signals with full adaptability. In power-saving mode, the circuit transitions to a static state where output levels are fixed, reducing power consumption while maintaining the ability to switch between states for flexibility when needed.
Solution Approach 2:
The patent changes the operational parameters of the amplification circuit by introducing a power-saving mode where the voltage levels of output signals are fixed to predetermined values regardless of input signals. This parameter change allows the circuit to operate with reduced power consumption by eliminating dynamic signal processing when full adaptability is not required, while still maintaining the capability to return to full operational flexibility when needed.
2Measurement precision
If the amplification circuit continuously processes input signals to generate output signals with varying voltage levels, then the signal processing accuracy is improved, but the power consumption increases
Solution Approach 1:
The patent applies partial action by implementing a power-saving mode where the amplification circuit performs only essential functions (maintaining fixed output voltage levels) rather than full signal processing. This partial operation reduces power consumption significantly while still maintaining basic circuit functionality, and the circuit can transition to full signal processing accuracy when needed based on control signals.
3Use of energy by moving object
If the semiconductor device uses a fixed voltage level for output signals, then the power consumption is reduced, but the operational speed and signal processing capability deteriorate
Solution Approach 1:
The patent makes the operational characteristics dynamic by allowing the circuit to switch between power-saving mode (fixed voltage levels, low power consumption) and normal mode (dynamic voltage levels, higher operational speed). The control circuit enables the amplification circuit to transition between these states, ensuring that operational speed is maintained when full performance is needed while reducing power consumption during idle or low-demand periods.
