Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-structure simulation apparatus is used, then the device complexity is reduced, but the adaptability to user-specific simulation requirements deteriorates
Solution Approach 1:
The simulation device is divided into multiple independent server units, each capable of processing signals for specific antennas. This modular segmentation allows the system to be configured flexibly for different simulation scenarios while maintaining manageable complexity through standardized interfaces between modules.
Solution Approach 2:
The server units are designed with universal functionality to handle multiple signal processing tasks including beamforming, signal generation, and parameter adjustment. This multi-functionality enables a single device architecture to adapt to various simulation requirements without requiring complete redesign for each application.
2Adaptability or versatility
If multiple radio frequency signal generators are used to provide diverse simulation outputs, then the versatility of simulation scenarios is improved, but the device complexity increases
Solution Approach 1:
Multiple signal processing functions are merged into integrated server units that can handle multiple antennas and signal types simultaneously. This consolidation reduces the overall number of separate signal generators needed while maintaining the versatility to simulate diverse radar and navigation scenarios.
Solution Approach 2:
The system employs dynamic signal routing and configurable server unit assignments that allow the same hardware infrastructure to adapt its functionality based on simulation requirements. This dynamic reconfiguration enables versatile simulation scenarios without requiring dedicated hardware for each scenario type.
3Productivity
If parallel processing of multiple antenna signals is implemented, then the productivity of signal generation is improved, but the device complexity increases
Solution Approach 1:
The parallel processing capability is achieved through segmentation into multiple independent server units that can operate simultaneously on different antenna signals. This segmentation enables high throughput by distributing processing loads across multiple units while keeping each unit's internal complexity manageable through standardized processing pipelines.
