Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple RF signal generators are used to model complex radio environments, then simulation capability and versatility are improved, but system complexity and control difficulty increase
Solution Approach 1:
The patent segments the complex task of multi-signal generation by introducing a simulation platform that separately handles scenario definition, signal generation, and control coordination. This divides the monolithic complex system into modular components (simulation platform, RF signal generators, digital interface) that can be independently managed and scaled.
Solution Approach 2:
The simulation platform acts as an intermediary between the user-defined simulation scenarios and the multiple RF signal generators. It coordinates and synchronizes the generators, managing the complexity of simultaneous multi-standard signal generation while providing a unified control interface.
2Manufacturing precision
If specialized solutions are used for specific radio technologies, then signal generation precision is improved, but adaptability to multiple incompatible technologies deteriorates
Solution Approach 1:
The simulation platform is designed with universal multi-functionality to support multiple incompatible radio technologies (5G NR, 4G LTE, Wi-Fi, RADAR, satellite) through a single unified system. It achieves this by implementing standardized interfaces and modular architecture that can accommodate different signal types while maintaining precise generation capabilities for each standard.
3Device complexity
If general purpose solutions are used for communication channels, then system simplicity is improved, but simulation accuracy of radio environments deteriorates
Solution Approach 1:
The simulation platform implements dynamic adaptability by allowing user-defined simulation scenarios that can be configured for specific radio environments. The system dynamically adjusts its behavior based on the selected scenario, switching between simplified general-purpose modes and detailed specialized simulations as needed.
4Reliability
If coherent generation of multiple RF signals is implemented, then signal synchronization and reliability are improved, but device complexity and control difficulty increase
Solution Approach 1:
The system implements feedback mechanisms through the digital interface that connects the simulation platform to the RF signal generators. This enables real-time monitoring and adjustment of signal parameters, ensuring coherent generation and synchronization while automatically managing the control complexity through closed-loop coordination.
