Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional diagnostic applications use technician assistance to detect and recreate problems, then diagnostic accuracy is improved, but cost and time consumption increase
Solution Approach 1:
The diagnostic system performs self-diagnosis through automated scripts that execute diagnostic routines, collect data, and generate reports without requiring technician intervention. The telematics unit autonomously configures diagnostic parameters, executes scripts, and transmits results, enabling the vehicle to diagnose its own issues.
Solution Approach 2:
The patent replaces the mechanical/manual process of technician-assisted diagnosis with an automated electronic system. Diagnostic scripts running on the telematics unit substitute for technician actions, automatically configuring diagnostics, executing test routines, and transmitting results without human physical intervention.
2Difficulty of detecting and measuring
If conventional diagnostic applications use technician assistance, then complex problem detection is improved, but cost increases
Solution Approach 1:
The patent replaces expensive technician expertise with automated diagnostic scripts and electronic data transmission. The telematics unit executes sophisticated diagnostic routines and transmits results electronically, eliminating the need for costly technician deployment while maintaining diagnostic capability for complex issues.
Solution Approach 2:
The system uses diagnostic scripts that replicate technician diagnostic procedures in software form. These digital copies of diagnostic routines execute automatically on the telematics unit, reproducing the diagnostic logic and data collection processes without requiring the physical presence of trained technicians.
3Productivity
If automated diagnostic scripts are used, then productivity is improved, but system complexity increases
Solution Approach 1:
The telematics unit serves multiple functions: it acts as a communication device, stores diagnostic scripts, executes diagnostic routines, collects diagnostic data, and transmits results. This multi-functional approach consolidates what would otherwise require separate dedicated diagnostic hardware into the existing telematics infrastructure.
Solution Approach 2:
The patent combines the diagnostic system with the existing telematics unit, merging script configuration, execution, data collection, and transmission functions into a single integrated platform. This consolidation leverages existing hardware and communication capabilities rather than adding separate diagnostic systems.
Data Source
AI summary
The present invention provides a method for providing automated vehicle diagnostic function within a mobile vehicle communication system. The method includes configuring a primary diagnostic script for a telematics equipped mobile vehicle, providing the primary diagnostic script to the mobile vehicle, executing the primary diagnostic script, and collecting diagnostic data based on the executed primary diagnostic script. The primary diagnostic script may recreate known problem sequences when executed or may trigger data capture when specific conditions exist. The step of configuring the primary diagnostic script may include determining at least one diagnostic script based on diagnostic options and retrieving the at least one determined diagnostic script. One or more diagnostic scripts may be combined into the primary diagnostic script.
