Preemptive Symptom Correlation in Vehicle Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diagnostic systems lack the ability to identify and correlate preemptive symptoms with specific vehicle types and corresponding work sequences, leading to reduced accuracy in diagnosing and preventing potential problems in similar vehicles.
Innovation Solution
A method and system that utilize a diagnostic database to correlate symptoms, problems, and work sequences, allowing for the identification of preemptive symptoms and associated work processes, which can be displayed to users for proactive maintenance and repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a diagnostic system uses general symptom identification without vehicle-type correlation, then the system complexity is reduced, but the diagnostic precision and ability to identify preemptive symptoms for specific vehicle types deteriorates
Solution Approach 1:
The diagnostic database is segmented by vehicle types, with each vehicle type having its own correlated symptom-problem-work sequence data. This allows the system to retrieve only the relevant subset of diagnostic information for the specific vehicle type being diagnosed, improving precision while managing complexity through organized data segmentation.
Solution Approach 2:
The system pre-correlates symptoms with problems and work sequences for each vehicle type during database construction. This preliminary organization of diagnostic data enables rapid retrieval of vehicle-type-specific preemptive symptoms without requiring complex real-time analysis, thus improving diagnostic precision while keeping the operational system relatively simple.
2Reliability
If the diagnostic system correlates symptoms with vehicle types and work sequences, then the ability to identify preemptive symptoms improves, but the time required to process and retrieve diagnostic information increases
Solution Approach 1:
The system performs the complex correlation of symptoms, problems, and work sequences for each vehicle type in advance during database construction. This preliminary action stores the correlated relationships in an organized structure that enables rapid retrieval during actual diagnostic operations, improving reliability while minimizing information retrieval time.
Solution Approach 2:
The system creates a digital copy of the correlated diagnostic data for each vehicle type in the database. This copied and stored information can be quickly retrieved and displayed without requiring real-time recalculation or complex processing, thus improving reliability of symptom identification while keeping retrieval time short.
3Ease of repair
If the system displays detailed work sequences for preemptive symptoms, then the ease of repair improves, but the amount of information presented to the user increases
Solution Approach 1:
The work sequence information is segmented into discrete, organized steps that can be displayed systematically. Each work sequence is broken down into manageable portions that can be presented to the user in a structured format, making complex repair information easier to follow while organizing the information load into digestible segments.
Data Source
AI summary
A system and method for determining work procedures through correlated symptoms are provided. The system made up of a diagnostic authoring apparatus for constructing and managing a diagnostic database. Information is stored in the diagnostic database that identifies vehicles that have the tendency to display certain symptoms in correlation with particular problems. These problems in the vehicles generally have a common solution for that type of vehicle. The problem may be common enough to check for a symptom preemptively, possibly before the vehicle owner is aware of it, or even prior to the manifestation of the symptom. The problem may warrant action taken to fix or avoid the problem. The system and method may associate and mark a problem with a preemptive symptom so a vehicle service/repair professional may be presented with the proper way to handle the associated problem for a particular vehicle.
