Vehicle Data Stream Paging for Faster Diagnostic Refresh
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle diagnostic systems struggle with quickly locating target data streams among multiple displayed streams and suffer from slow refreshing speeds due to unordered display and redundant data re-reading.
Innovation Solution
A method and system for sorting vehicle data streams by title in ascending or descending order and paging displaying them, allowing quick selection and efficient refreshing of target data streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle data streams are displayed in chronological reading order, then all data streams can be displayed, but diagnosis workers cannot quickly locate target data streams
Solution Approach 1:
The patent divides the data stream display into multiple pages, with each page showing a subset of data streams. This segmentation allows workers to quickly locate target data streams by navigating through organized pages rather than searching through all streams in chronological order, directly improving location speed while maintaining complete data accessibility.
Solution Approach 2:
The patent pre-sorts data streams by title before display, performing the organization action in advance rather than requiring workers to search through unorganized chronological data. This preliminary sorting action enables quick location of target streams while preserving all data information for diagnostic purposes.
2Productivity
If diagnosis equipment re-reads data from many vehicle data streams during refreshing, then data can be updated, but refreshing speed becomes slow
Solution Approach 1:
The patent extracts and caches data stream titles and metadata separately from the full data stream content. During refreshing, the system only needs to update the cached title information rather than re-reading entire data streams, significantly improving refreshing speed while maintaining data integrity for diagnostic use.
Solution Approach 2:
The patent performs preliminary data reading and caching during the initial data stream acquisition phase. This preliminary action stores essential information that can be quickly updated during refreshing operations, reducing the time needed for subsequent refresh cycles while ensuring data accuracy.
3Ease of operation
If multiple data streams are displayed without paging, then all data is visible, but data stream titles are displayed out of order and hard to navigate
Solution Approach 1:
The patent implements paging that divides data streams into manageable groups displayed on separate pages. Each page shows data streams in sorted order by title, providing systematic navigation through the data. This segmentation improves navigability while the structured paging mechanism keeps the display organization systematic rather than complex.
Solution Approach 2:
The patent pre-sorts all data stream titles alphabetically before distributing them across pages. This preliminary sorting action ensures that data streams are always displayed in ordered fashion regardless of which page is currently viewed, improving navigation ease while maintaining a simple sorted organization rather than complex dynamic arrangements.

AI summary
The present application provides a vehicle data stream displaying method and system, and a vehicle diagnostic device. The method includes: numbering at least one vehicle data stream that is displayed out of order; sorting the vehicle data stream, and displaying the vehicle data stream according to a sorting order; selecting at least one target data stream from the vehicle data stream according to a target data stream selection instruction; paging displaying the at least one target data stream; obtaining number data of a target data stream displayed on each page, and establishing a correlation relationship between a display page number and the number data; and paging refreshing a target data stream displayed on a current page according to the correlation relationship between the display page number and the number data, if a refreshing instruction is received. According to the present application, a diagnosis worker can conveniently and quickly find a target data stream from many vehicle data streams, and a data stream refreshing speed when the target data stream is viewed can be increased.
