Navigation Icon Data Array Storage for Fast Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems face delays in loading and displaying icons on digital maps due to time-consuming retrieval from databases, which is particularly problematic in embedded systems with limited computational resources.
Innovation Solution
The system employs data arrays to store icons in memory with faster retrieval speeds, allowing icons to be loaded and displayed quickly by referencing their positions within the arrays, thereby avoiding the need for separate database access during navigation.

Engineering Contradiction Analysis
1Quantity of substance
If icons are stored in a database for navigation systems, then the system can manage multiple icons, but the retrieval time increases causing delays in loading and displaying icons on digital maps
Solution Approach 1:
The patent divides icon storage into two separate structures: a database for storing icon data and a data array for fast retrieval. The data array is segmented into multiple entries, each containing icon data and position information, allowing rapid access without querying the entire database.
Solution Approach 2:
The data array acts as an intermediary between the database and the display system. Instead of directly querying the database during navigation, the system first retrieves pre-processed icon position data from the data array, which mediates the interaction and significantly reduces retrieval time.
2Speed
If the navigation system uses fast memory for icon storage, then retrieval speed improves, but the system complexity increases due to additional memory management components
Solution Approach 1:
The patent merges the icon data storage function with the fast retrieval function by combining the database and data array into a unified memory management structure. The data array is integrated with the database, allowing both functions to coexist without requiring separate independent systems.
Solution Approach 2:
The system performs preliminary action by pre-processing and storing icon position data in the data array before navigation occurs. This advance preparation allows the navigation system to quickly retrieve icon information without performing complex database queries during real-time navigation.

AI summary
A navigation system may use digital maps to represent cartographic features during guidance along a route to a destination requested by a user. A system and method are provided for management of icons used to represent the cartographic features by storing data for multiple icons in a data array representing an image containing the plurality of icons.
