Map Update Prioritization for Navigation Display Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map information distribution systems fail to effectively distinguish between newly constructed roads and other updated sections, making it difficult for users to recognize and confirm updated content in navigation devices.
Innovation Solution
The system assigns scores to updated content based on factor information and prioritizes the display of updated road and object information, allowing users to easily identify newly opened or changed sections by sending update request information to the map information distribution center, receiving and processing update information, and displaying prioritized content on the navigation device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If map information is updated automatically from the distribution center, then the map data is kept current, but users cannot easily distinguish newly constructed roads from other updated sections
Solution Approach 1:
The patent segments updated map information into distinct categories (newly constructed roads, road expansions, toll changes, etc.) and assigns specific visual markers or symbols to each category. This segmentation allows users to clearly distinguish different types of updates while maintaining comprehensive map data currency through automatic distribution.
2Loss of information
If all updated content is displayed equally, then complete information is provided, but important updates like newly opened expressways are indistinguishable from minor changes
Solution Approach 1:
The patent applies local quality by assigning different visual properties (colors, symbols, sizes) to different types of updated content based on their importance. Newly constructed roads receive prominent visual treatment, while minor updates have subtler markers. This allows all updates to be displayed completely while making important changes easily recognizable through differentiated visual qualities.
3Quantity of substance
If update information is distributed without prioritization, then all updates are transmitted, but users cannot easily confirm important changes
Solution Approach 1:
The patent performs preliminary action by pre-categorizing and prioritizing update information at the distribution center before transmission. Updates are tagged with importance levels and category identifiers in advance, allowing the navigation device to efficiently display and highlight important changes without losing any update information. This preliminary organization enables users to quickly identify significant updates while maintaining complete information transmission.

AI summary
Map information distribution systems, methods, and programs that update map information based and distribute the update information, send update request information for requesting the update information of the map information, receive the update request information, and obtain the update information corresponding to the received update request information. The systems, methods, and programs obtain updated content corresponding to the obtained update information, assign a score to the updated content based on factor information corresponding to the obtained updated content, assign an order of priority to the respective updated content based on the scores assigned to the respective updated content, distribute the update information and the prioritized updated content, update the map information based on the received update information, and notify a user of the received updated content based on the order of priority assigned to the updated content.
