Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single wireless link is used for communication between nodes, then the device complexity is reduced, but the reliability deteriorates due to interference and link failures
Solution Approach 1:
The patent segments the wireless communication path into multiple independent micro-routes between transmitter and receiver nodes. Each micro-route represents a distinct propagation path through the wireless medium, allowing diversification of communication channels to avoid single-point failures and interference affecting the entire link.
Solution Approach 2:
The patent changes the spatial parameter of wireless communication by exploiting multiple propagation paths with different angles of departure and arrival. By selecting micro-routes with diverse spatial characteristics, the system achieves reliability improvement through parameter diversity while managing complexity through correlation-based selection.
2Adaptability or versatility
If multiple micro-routes are characterized and monitored, then the adaptability improves for selecting alternative paths, but the measurement precision requirements increase
Solution Approach 1:
The patent performs preliminary characterization of multiple micro-routes before actual communication needs arise. By pre-measuring and storing correlation metrics between different micro-routes, the system prepares adaptability data in advance, reducing the precision burden during real-time selection when conditions change.
Solution Approach 2:
The patent introduces correlation measurement as an intermediary metric that simplifies the adaptability problem. Instead of directly measuring and comparing complex link quality parameters across multiple routes, the system uses correlation values to predict which micro-routes are likely to maintain quality when others fail, reducing measurement precision requirements.
3Reliability
If micro-routes with high correlation are selected for diversity, then the ease of operation improves, but the reliability deteriorates as they are affected by the same interfering signals
Solution Approach 1:
The patent implements feedback through correlation measurements that inform the micro-route selection process. By continuously monitoring the correlation between candidate micro-routes and selecting those with appropriate correlation levels, the system automatically adjusts to maintain reliability while managing operational complexity through intelligent feedback-driven selection.
