Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If different types of LP-WURs are supported in the communication network, then power consumption is reduced and device functionality is enhanced, but measurement differences and compatibility issues arise among different LP-WUR types
Solution Approach 1:
The patent applies parameter changes by introducing receiver-type-specific decision thresholds and offset parameters. Different LP-WUR types (envelope detection vs. OFDM-based) use different threshold values and offset corrections to compensate for their inherent measurement differences. This allows each receiver type to operate independently with optimized parameters, maintaining measurement compatibility across diverse low-power receiver implementations.
2Measurement precision
If receiver-specific decision thresholds and offset parameters are configured, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring receiver-type-specific decision thresholds and offset parameters in the terminal device. Instead of calculating these parameters in real-time during operation, the device stores multiple sets of parameters corresponding to different LP-WUR types and automatically selects the appropriate set based on the active receiver type. This approach achieves high measurement precision while minimizing runtime computational complexity.
3Adaptability or versatility
If multiple types of LP-WURs are implemented, then adaptability is enhanced, but measurement errors increase due to different signal processing approaches
Solution Approach 1:
The patent applies local quality by customizing measurement parameters specifically for each LP-WUR type. Envelope detection-based receivers use different decision thresholds and offset corrections compared to OFDM-based receivers, accounting for their distinct signal processing characteristics. This localized parameter optimization ensures that each receiver type achieves accurate measurements despite fundamental differences in their operating principles.
