Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation information is transferred from radio network to subscriber over air, then navigation instructions can be provided to user, but communication cost increases
Solution Approach 1:
The patent pre-fetches and stores navigation instruction data in the subscriber device before the actual navigation session. The system predicts future navigation needs and downloads relevant data in advance when network conditions are favorable, eliminating the need for continuous real-time data transfer during navigation.
Solution Approach 2:
The patent implements local storage of navigation data in the subscriber device, allowing the device to cache and store navigation instructions locally. This enables the system to transfer only essential data over the air while storing detailed navigation information locally, reducing overall communication costs.
2Device complexity
If navigation systems use standard routing algorithms, then route calculation is simple, but routes may pass through areas with poor communication infrastructure
Solution Approach 1:
The patent dynamically adjusts routing decisions based on real-time network coverage information. The system incorporates communication infrastructure data into the routing algorithm, allowing it to adaptively select routes that balance navigation efficiency with communication reliability. Routes are dynamically optimized considering both geographic and network topology.
Solution Approach 2:
The patent introduces network coverage information as an intermediary layer between the navigation system and route selection. This intermediary data layer provides communication infrastructure status that mediates the routing decision-making process, enabling the system to avoid areas with poor coverage while maintaining reasonable route efficiency.
3Measurement precision
If real-time navigation updates are provided continuously, then navigation accuracy is improved, but communication requirements increase
Solution Approach 1:
The patent implements periodic navigation updates instead of continuous real-time updates. The system sends navigation instructions at predetermined intervals or based on triggering events such as reaching specific waypoints, maintaining adequate navigation accuracy while significantly reducing communication frequency and data transfer requirements.
Solution Approach 2:
The patent provides navigation updates selectively rather than continuously. The system determines which updates are truly necessary based on the user's current location, destination, and navigation context, sending only the essential navigation information needed at each stage of the journey.
