Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle diagnostic devices struggle to display data streams in a manner that meets user requirements, as the graphical representation of data often lacks sufficient detail for comprehensive analysis.
Innovation Solution
A method and system that allow users to set a display range for diagnostic data, enabling zooming in or out based on user instructions, and storing diagnostic data to display relevant information effectively within the chosen range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diagnostic data is displayed in a fixed graphical range, then the display is simple and stable, but the user cannot perform comparative analysis over different time periods
Solution Approach 1:
The patent implements dynamic display range adjustment by allowing users to zoom in and zoom out of the graphical data stream display. The system transitions from a fixed display range to a dynamic one where the display range can be expanded or contracted based on user needs, enabling comparative analysis of diagnostic data across different time periods while maintaining operational simplicity through intuitive zoom controls
Solution Approach 2:
The system changes the display parameter (display range) from a fixed value to a variable that can be adjusted through zoom-in and zoom-out operations. By modifying the time range parameter of the displayed data stream, users can view different portions of the diagnostic data without changing the underlying data storage or processing mechanisms
2Quantity of substance
If a large quantity of diagnostic data is stored for long-term analysis, then comparative diagnosis is enabled, but the data management complexity increases
Solution Approach 1:
The system performs preliminary data collection and storage continuously in the background, accumulating diagnostic data over time without requiring user intervention. This preliminary action ensures that sufficient historical data is available for later comparative analysis, while the automated nature of the process minimizes data management complexity
Solution Approach 2:
The system automatically manages the stored diagnostic data, including continuous data collection, storage, and organization, without requiring manual intervention for data management tasks. The self-service mechanism handles large quantities of data through automated processes, reducing the complexity burden on users
3Measurement precision
If the display shows detailed graphical data for precise fault analysis, then diagnostic precision improves, but the overview capability is reduced
Solution Approach 1:
The display system dynamically adjusts between detailed and overview modes through zoom operations. Users can zoom in to view detailed graphical data for precise fault analysis, then zoom out to regain overview capability. This dynamic switching allows the system to provide both high measurement precision and broad display scope versatility depending on the current analytical needs

AI summary
The present application is applicable to the technical field of vehicle diagnosis, and provides a method and a system for graphically displaying a data stream and a vehicle diagnostic device. The method comprises: receiving and storing diagnostic data; graphically displaying the diagnostic data within a display range according to the display range set by a user; and receiving a zoom-in instruction or a zoom-out instruction sent by the user, zooming in or zooming out the display range according to a preset condition, and graphically displaying the diagnostic data within a zoomed in or zoomed out display range. In this process, the user can randomly zoom in and zoom out a displayed graph, which helps the user to comparatively look over different diagnostic data received within a long period of time so as to rapidly discover a fault or find out a fault cause.
