Driver Information System Tile Data Deduplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver information systems require increased memory and loading time due to redundant data storage of identical map tiles on the data carrier and in working memory.
Innovation Solution
Implement a method where data from different tiles with the same content are stored only once on the data carrier, using a table of contents to assign each tile a unique storage location, reducing redundant data storage and loading requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each tile is stored with its data sets on the data carrier even if they are identical to data sets from other tiles, then the data carrier contains complete data for all tiles, but the memory requirement on the data carrier increases and the loading time increases
Solution Approach 1:
The patent merges identical data sets from multiple tiles into a single stored copy on the data carrier. When the same data appears in multiple tiles, it is stored only once and referenced by multiple tiles through the table of contents, reducing total storage requirements while maintaining data accessibility for all tiles.
Solution Approach 2:
The patent creates universal data storage where a single data set serves multiple tiles simultaneously. The table of contents structure allows one stored data set to fulfill the data requirements of multiple different tiles, making the storage system multi-functional and efficient.
2Reliability
If each tile is stored with its data sets on the data carrier even if they are identical to data sets from other tiles, then the data carrier contains complete data for all tiles, but the loading time increases
Solution Approach 1:
The patent merges identical data sets from multiple tiles into a single stored copy on the data carrier. When the same data appears in multiple tiles, it is stored only once and referenced by multiple tiles through the table of contents, reducing total storage requirements while maintaining data accessibility for all tiles.
Solution Approach 2:
The patent performs preliminary organization of data into a table of contents structure that identifies identical data sets across tiles before loading. This pre-organization allows the system to load each unique data set only once and quickly reference it for multiple tiles, rather than loading redundant copies.
3Productivity
If the working memory has increased storage capacity to accommodate all tile data, then all map data can be loaded simultaneously, but the system cost and complexity increase
Solution Approach 1:
The patent segments the table of contents into different data structures (lists, tables, files) that organize tiles and their corresponding data set locations. This segmentation allows efficient indexing and retrieval without requiring the working memory to store all tile data simultaneously, reducing memory capacity requirements while maintaining access speed.
Solution Approach 2:
The patent adds a dimensional layer of abstraction with the table of contents structure, which acts as an index between the physical data storage and the logical tile representation. This intermediate dimension allows the system to reference data efficiently without loading all data into working memory, reducing the memory dimension requirement.
