Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed sweep parameters are used in level radar devices, then device operation is simple, but measurement accuracy deteriorates due to variations in measurement environments and materials
Solution Approach 1:
The patent implements dynamic adjustment of sweep parameters (frequency, bandwidth, power) based on real-time measurement conditions. The control unit automatically modifies these parameters during operation to optimize measurement accuracy for different materials and environments, transforming the static parameter system into a dynamic adaptive one.
Solution Approach 2:
The system incorporates feedback mechanisms where measurement results and environmental data are continuously monitored. The control unit uses this feedback information to automatically adjust sweep parameters, creating a closed-loop control system that improves measurement accuracy without requiring manual expert intervention.
2Measurement precision
If expert knowledge is required for parameter adjustments, then measurement accuracy can be optimized, but ease of operation deteriorates
Solution Approach 1:
The level radar device performs self-optimization of sweep parameters through automated control. The control unit independently analyzes measurement conditions and adjusts frequency, bandwidth, and power settings without requiring external expert knowledge, enabling the system to serve itself and achieve optimal performance automatically.
Solution Approach 2:
The system automatically changes sweep parameters (frequency, bandwidth, power) based on detected measurement conditions. This automated parameter adaptation allows the device to optimize measurement accuracy for different materials and environments without requiring user expertise in parameter selection.
3Reliability
If transmission power is increased to improve signal-to-noise ratio, then measurement reliability improves, but energy consumption increases
Solution Approach 1:
The transmission power is dynamically adjusted based on real-time measurement conditions and detected signal quality. The control unit increases power only when necessary to maintain adequate signal-to-noise ratio, and reduces power when conditions permit, optimizing the balance between reliability and energy consumption.
Solution Approach 2:
The system automatically modifies transmission power as a sweep parameter based on measurement conditions. This adaptive power control allows the device to maintain reliable measurements with minimal energy consumption by adjusting power levels to match actual measurement needs rather than operating at fixed high power.
