Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If navigation path is determined based on path length, traffic condition, and time consumption, then navigation efficiency is improved, but network communication quality deteriorates
Solution Approach 1:
The patent segments the navigation path into multiple geographical regions and divides network quality assessment into separate dimensions (signal quality, signal strength, resource capacity). This allows independent optimization of navigation efficiency and network quality by evaluating different path segments against multiple criteria rather than a single composite metric.
Solution Approach 2:
The patent introduces a new dimension to path planning by incorporating network communication quality as a separate planning criterion alongside traditional navigation parameters. The system builds a communication resource heat database that maps geographical regions to network quality metrics, enabling three-dimensional path optimization that balances navigation efficiency with communication reliability.
2Device complexity
If navigation path does not consider communication resource heat, then path planning simplicity is maintained, but communication stability deteriorates
Solution Approach 1:
The system performs preliminary action by pre-building a communication resource heat database that maps geographical regions to network quality metrics before actual navigation occurs. This pre-computed database allows the path planning algorithm to quickly query and select optimal paths without performing complex real-time network analysis, thus maintaining simplicity while improving stability.
Solution Approach 2:
The communication resource heat database serves as an intermediary between geographical location data and network quality requirements. It translates physical geographical regions into predicted network quality metrics, enabling the path planning system to consider communication stability without directly managing complex network protocols or real-time signal analysis.
3Device complexity
If traditional navigation parameters are used for path planning, then computational complexity is reduced, but network service continuity deteriorates
Solution Approach 1:
The patent changes the parameters used for path planning from traditional single-dimension metrics (distance, time, traffic) to multi-dimensional parameters that include network quality metrics (signal quality, signal strength, resource capacity). The system transforms the path planning problem into a multi-parameter optimization problem that simultaneously considers navigation efficiency and network service continuity, achieving better stability without excessive computational complexity through structured database queries and predefined evaluation criteria.
