Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verified safety software is used for zone updates, then reliability is improved, but productivity deteriorates due to time-consuming development, testing, and review processes
Solution Approach 1:
The system separates verification functionality from the main autonomous vehicle control software. A dedicated verifying entity independently validates zone updates without requiring full safety software certification processes, thus improving update speed while maintaining reliability through specialized verification
Solution Approach 2:
A verifying entity acts as an intermediary between zone update providers and autonomous vehicles. This intermediary performs validation and verification of zone updates, ensuring safety while enabling faster updates without requiring complete safety software re-certification
2Reliability
If physical tests are performed by test engineers after each update, then reliability is improved, but productivity deteriorates due to production halts
Solution Approach 1:
The system replaces physical field testing with automated computational verification. The verifying entity uses algorithmic validation and error-detecting codes to verify zone updates remotely, eliminating the need for test engineers to physically test each update and thereby maintaining production continuity while ensuring reliability
3Reliability
If zone updates require temporary stop of production, then reliability is improved through thorough verification, but productivity deteriorates due to operational interruptions
Solution Approach 1:
Zone updates are verified in advance by the verifying entity using automated validation processes and error-detecting codes before deployment. This preliminary verification ensures update accuracy while enabling seamless deployment without operational interruptions, as the verification is completed beforehand
4Reliability
If centralized safety software is used for verification, then reliability is improved, but device complexity increases due to dedicated verification infrastructure
Solution Approach 1:
The verifying entity is designed as a universal verification platform that can validate multiple types of zone updates for different autonomous vehicles using standardized procedures and error-detecting codes. This multi-functional approach ensures thorough verification while reducing overall system complexity by consolidating verification capabilities into a single versatile entity
