Navigation System Temporal Management Offline Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems face challenges in updating data efficiently and providing convenient, meaningful information, with client-based systems being cumbersome and costly due to large memory requirements, while thin client systems rely on wireless networks and lack real-time updates in areas without coverage.
Innovation Solution
A navigation system with temporal management that allows users to specify a time and location for updating relevant information, enabling the client to request and receive time-of-interest data from a server, which automatically updates the local content cache based on elapsed time, ensuring accurate and relevant information is available for navigation and location-based services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If client-based navigation system stores all map content and location based services locally, then navigation service is available offline, but device size and memory requirements increase significantly
Solution Approach 1:
The patent segments navigation data into two categories: static data (maps, points of interest) stored locally in the client device, and dynamic data (traffic conditions, route updates) retrieved from server when needed. This segmentation allows the device to maintain essential offline navigation capabilities while avoiding storage of large amounts of transient data, thus reducing device size while preserving reliability.
2Loss of information
If thin client navigation system loads all map data from server, then data is always updated, but wireless network coverage is required for navigation
Solution Approach 1:
The patent implements preliminary action by pre-loading static navigation data (maps, points of interest, business information) into the client device's local storage before offline use is needed. This allows the client to have access to essential navigation data without requiring continuous network connectivity, while still enabling periodic updates when network is available.
3Reliability
If client-based navigation system stores large amount of information locally, then offline navigation is possible, but data update becomes inconvenient
Solution Approach 1:
The patent implements periodic action by automatically updating dynamic navigation data (traffic conditions, route information) at scheduled intervals or when specific triggers occur (e.g., entering a new geographic area, completing a navigation task). This periodic update mechanism maintains data freshness without requiring manual user intervention, thus improving ease of operation while preserving offline capability.
4Loss of information
If thin client navigation system retrieves data from server, then real-time information is available, but service is unavailable without network coverage
Solution Approach 1:
The patent applies local quality by differentiating between data types and their update requirements. Static data (maps, POI information) is stored locally with high quality and detail for offline use, while dynamic data (traffic, weather) is retrieved from server with appropriate update frequency. This allows the system to adapt to different operational contexts (online/offline) while maintaining information relevance.
