Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the receiving device maintains high-power reception mode during backscatter reading operations, then the reception sensitivity is improved, but the power consumption increases
Solution Approach 1:
The receiving device dynamically adjusts its reception parameters based on the backscatter reading operation state. The device switches between different reception modes (high-sensitivity mode and normal mode) depending on whether a backscatter reading operation is detected, making the system adaptable to different operational requirements rather than maintaining a fixed high-power state
Solution Approach 2:
The device receives an indication of an upcoming backscatter reading operation in advance and proactively adjusts its reception parameters before the actual operation occurs. This preliminary adjustment allows the device to optimize power consumption by being in high-sensitivity mode only when necessary, rather than maintaining it continuously
2Measurement precision
If the receiving device adjusts reception parameters for backscatter reading operations, then the reading accuracy is improved, but the device complexity increases
Solution Approach 1:
The receiving device monitors for indications of backscatter reading operations and uses this feedback to automatically adjust its reception parameters. The system implements a closed-loop control mechanism where the detection of a backscatter operation triggers the appropriate parameter adjustments, eliminating the need for manual configuration while maintaining high reading accuracy
Solution Approach 2:
The receiving device autonomously manages its own reception parameter adjustments based on the detected operation type. The device self-configures to use high-sensitivity reception modes when backscatter reading operations are detected, without requiring external control or complex manual intervention, thereby simplifying the overall system architecture
3Speed
If hardware components remain active during backscatter reading operations, then the response time is improved, but the power consumption increases
Solution Approach 1:
The receiving device uses periodic indication signals to trigger hardware activation. Instead of keeping hardware continuously active, the device receives periodic indications of upcoming backscatter reading operations and activates hardware components only when needed, creating an on-demand operation pattern that balances response time requirements with power consumption optimization
