Engineering Contradiction Analysis
1Productivity
If multiple chips are used for energy harvesting and signal processing, then functional completeness is achieved, but transmission delay increases and processing efficiency decreases
Solution Approach 1:
The patent integrates the amplifier, analog-to-digital converter, digital filter, processor, and radio frequency signal transceiver into a single-chip controller. This merging of previously separate chips into one integrated unit eliminates the need for signal transmission between multiple chips, thereby reducing transmission delay and improving signal processing efficiency.
2Productivity
If multiple amplifiers are used in multi-chip architecture, then signal processing capability is enhanced, but power consumption increases
Solution Approach 1:
The patent combines multiple amplifier functions into a single-stage amplifier within the integrated controller chip. This consolidation reduces the total number of amplifiers needed compared to multi-chip architectures, thereby lowering overall power consumption while maintaining signal processing capability.
3Measurement precision
If external assistance components are disposed to increase signal resolution, then measurement precision is improved, but circuit cost and power consumption increase
Solution Approach 1:
The patent integrates the analog-to-digital converter and digital filter directly into the controller chip, eliminating the need for external assistance components. This integration achieves high signal resolution through the combined ADC and digital filtering capabilities while reducing circuit complexity and the number of external components required.
4Adaptability or versatility
If conventional multi-chip architecture is used, then functional completeness is achieved, but the number of external components increases
Solution Approach 1:
The patent integrates all necessary functional blocks (amplifier, ADC, digital filter, processor, and RF transceiver) into a single-chip controller, thereby maintaining functional completeness while dramatically reducing the number of external components needed compared to conventional multi-chip architectures.
