Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive real-world testing and simulation of diverse driving scenarios are performed, then verification and validation of autonomous vehicle functions is improved, but resource consumption and time required increase significantly
Solution Approach 1:
The patent divides test specifications into reusable specification parts that can be independently stored, retrieved, and combined. This segmentation allows the testing system to reuse valid test cases across different scenarios, reducing redundant testing time while maintaining comprehensive verification coverage.
Solution Approach 2:
The system pre-stores validated specification parts in a database before actual testing. By preparing and storing test specifications in advance, the system avoids repeating already validated tests, thereby reducing overall testing time while ensuring thorough verification of autonomous vehicle functions.
2Reliability
If extensive real-world testing and simulation of diverse driving scenarios are performed, then verification and validation of autonomous vehicle functions is improved, but cost increases significantly
Solution Approach 1:
The patent recovers and reuses validated specification parts from previous testing instead of creating new test cases from scratch. By discarding redundant testing efforts and recovering valid test specifications, the system reduces computational resources and time consumption while maintaining comprehensive verification coverage.
Solution Approach 2:
The specification parts are designed to be universal and can be applied across multiple different driving scenarios and test cases. This multi-functionality allows a single validated specification to serve multiple testing purposes, reducing the total resource consumption required for comprehensive verification and validation.
3Productivity
If specification parts are stored and reused, then testing efficiency is improved, but management complexity of specification parts increases
Solution Approach 1:
The system creates digital copies of validated specification parts and stores them in a centralized database. This copying approach enables efficient retrieval and reuse of test specifications without requiring complex manual management, as the system automatically handles duplication and versioning of specification parts.
Solution Approach 2:
The system incorporates feedback mechanisms to track which specification parts have been used, their effectiveness, and any necessary updates. This feedback loop simplifies management by automatically identifying which specifications need maintenance or updates, reducing manual intervention requirements while maintaining high testing efficiency.
