Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional digital computing is used for electromagnetic environment emulation, then the system structure is simple and easy to implement, but the processing speed, memory storage capacity, and signal transfer speed are insufficient to achieve real-time emulation
Solution Approach 1:
The patent replaces conventional digital computing systems with an optical computing system. Optical signal processing substitutes digital electronic processing, enabling significantly higher signal transfer speeds and processing capacities while maintaining system functionality for electromagnetic environment emulation
Solution Approach 2:
The optical computing system is divided into multiple processing element nodes organized in a scalable architecture. Each node can independently process electromagnetic signal interactions, and nodes can be added or removed to adjust emulation complexity, resolving the contradiction between speed and system complexity
2Quantity of substance
If conventional digital computing is used, then the system is easy to implement, but the processing capacity and memory storage are insufficient for complex simulated scenarios
Solution Approach 1:
Multiple processing element nodes are merged into a unified optical computing system that shares common optical interconnect resources. This merging provides large collective memory storage capacity and processing power while avoiding the complexity of completely independent systems for each node
Solution Approach 2:
The system transitions from two-dimensional digital signal processing to three-dimensional optical signal processing in space, wavelength, and time domains. This dimensional expansion enables vastly increased storage capacity and processing power without linearly increasing system complexity
3Productivity
If optical converters and switch matrix are introduced to optimize signal placement, then signal transfer efficiency improves and digital traffic is reduced, but the device complexity increases
Solution Approach 1:
Optical converters and switch matrix act as intermediary components between electromagnetic signal sources and processing element nodes. These intermediaries optimize signal routing and placement, improving processing efficiency while isolating the complexity of signal management from the core processing nodes
Solution Approach 2:
The switch matrix automatically routes optical signals between processing elements based on simulated geographic location and resource loading conditions without external intervention. This self-service capability improves signal processing efficiency while minimizing the control complexity required
