Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle diagnostic tools are cumbersome to navigate, requiring extensive menu navigation to access various functions, making it difficult for technicians to efficiently retrieve and analyze diagnostic trouble codes and perform tests.
Innovation Solution
A vehicle diagnostic tool featuring a graphical user interface (GUI) with a diagnostic hub that allows for intuitive navigation and a continuous data buffer for recording and analyzing data streams, enabling technicians to easily read DTCs, perform special tests, and view diagnostic information through a touch screen display with interactive functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional menu-based navigation is used in diagnostic tools, then comprehensive functionality is provided, but navigation complexity and time consumption increase significantly
Solution Approach 1:
The diagnostic tool interface is segmented into a hierarchical structure with a diagnostic hub at the top level and multiple functional modules (read DTCs, view data stream, perform tests, etc.) at subsequent levels. This segmentation allows users to access frequently used functions directly from the hub while maintaining comprehensive functionality, reducing navigation steps for common operations.
Solution Approach 2:
The diagnostic hub pre-organizes and pre-positions frequently accessed functions and data streams in a readily available interface layer. By preparing the interface structure in advance with quick-access buttons and automated data buffering, the system eliminates the need for technicians to navigate through multiple menu levels during diagnostic procedures.
2Productivity
If extensive menu navigation is required, then all diagnostic functions can be accessed, but operational efficiency decreases
Solution Approach 1:
The diagnostic hub serves as a universal interface that provides multiple functions through a single structured access point. It consolidates diverse diagnostic capabilities (reading DTCs, viewing data streams, running tests, clearing codes) into a unified hub structure, allowing technicians to access any function through a consistent, simplified navigation pattern rather than navigating through multiple complex menu systems.
Solution Approach 2:
The diagnostic hub acts as an intermediary layer between the user and the underlying complex diagnostic system. It translates simple user selections into appropriate diagnostic functions, shielding users from the complexity of the underlying system architecture while maintaining access to all diagnostic capabilities through a simplified interface.
3Measurement precision
If real-time data analysis is performed, then diagnostic accuracy improves, but data processing requirements and system resources increase
Solution Approach 1:
The system performs preliminary data buffering and pre-processing of diagnostic data streams in the background, preparing data for analysis before the user needs to view or act on it. This preliminary action reduces the processing burden during actual diagnostic analysis by having data ready in optimized formats, improving analysis speed and accuracy without proportionally increasing real-time processing resources.
Solution Approach 2:
The diagnostic tool maintains continuous data buffering and background processing of data streams, ensuring that data is always ready for immediate analysis when needed. This continuous operation allows for real-time diagnostic accuracy while distributing the processing workload over time rather than concentrating it during peak analysis moments, optimizing resource utilization.

AI summary
A graphical user interface that is capable of being used on a computing device, such as a vehicle diagnostic tool. The graphical user interface includes various buttons that when actuated causes the vehicle diagnostic tool to perform a corresponding functionality such as read diagnostic trouble codes and collect and display a data stream of diagnostic data of a vehicle. The graphical user interface also displays buffered data in a data window and the data may be moved using various input buttons.
