Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual or visual inspection methods are used for vehicle condition examination, then the inspection can be performed with simple equipment, but the inspection process is time-consuming and inefficient
Solution Approach 1:
The patent replaces manual visual inspection with an electronic diagnostic system that automatically queries control units and analyzes vehicle data. The system uses electronic communication protocols to interact with vehicle control units, eliminating the need for manual observation and significantly reducing inspection time while improving accuracy through automated data analysis.
2Reliability
If electronic diagnostic systems are implemented for comprehensive vehicle monitoring, then all safety-relevant components can be monitored electronically, but the system complexity and cost increase
Solution Approach 1:
The patent implements a universal diagnostic interface that can communicate with multiple different control units across various vehicle types through standardized protocols. The system is designed to be multi-functional, handling different communication protocols (CAN, LIN, K-Line) and adapting to various vehicle architectures, which reduces overall system complexity despite the comprehensive monitoring capabilities.
Solution Approach 2:
The diagnostic system uses an intermediary adapter or interface layer that translates between different vehicle-specific protocols and the universal diagnostic platform. This mediator approach allows comprehensive monitoring without requiring complex direct integration with each individual control unit, simplifying the overall system architecture.
3Measurement precision
If the diagnostic system is configured for specific vehicle types, then accurate diagnostics can be performed for that vehicle type, but the system cannot be rapidly adapted to different vehicle types
Solution Approach 1:
The patent implements a dynamic configuration system where the diagnostic parameters, communication protocols, and control unit addresses can be automatically adjusted based on the detected vehicle type. The system uses vehicle identification data to dynamically load appropriate configuration profiles, enabling accurate diagnostics for each vehicle type while allowing rapid adaptation when switching between different vehicle models.
Solution Approach 2:
The system changes operational parameters such as communication baud rates, protocol types, and query commands based on the specific vehicle type being diagnosed. By storing multiple configuration profiles and automatically selecting the appropriate one based on vehicle identification, the system maintains high diagnostic accuracy across different vehicle types without requiring manual reconfiguration.
4Loss of information
If comprehensive data collection from all control units is performed, then complete vehicle condition assessment is achieved, but the data processing time and computational resources increase
Solution Approach 1:
The patent implements a hierarchical data collection approach that first queries critical safety-relevant parameters immediately, then optionally collects additional diagnostic data based on the initial assessment and available time. The system prioritizes data collection based on safety importance, ensuring complete assessment of critical systems while allowing flexible adjustment of non-critical data collection to balance information completeness with processing time.
