Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If autonomous vehicle testing is conducted on real roads to improve test accuracy, then the test reflects real road conditions, but the safety of testing deteriorates due to complex and dangerous real road conditions
Solution Approach 1:
The patent creates a virtual copy of the real road environment through building a three-dimensional map and simulating road conditions, obstacles, and traffic scenarios in a virtual space. This allows testing to be conducted on a replicated environment rather than the actual road, maintaining test accuracy while eliminating safety risks associated with real road testing
Solution Approach 2:
The patent introduces a virtual environment as an intermediary between the autonomous vehicle and the real road. The vehicle operates in a virtual space that mediates the interaction between the testing system and real-world conditions, allowing safe testing while preserving the ability to evaluate real road performance
2Reliability
If simulated obstacles are deployed to improve test safety, then human safety and vehicle damage are avoided, but the complexity of the testing system increases
Solution Approach 1:
The patent uses virtual copies of obstacles and road elements in a three-dimensional map rather than physical simulations. This digital replication approach simplifies the system compared to building physical test environments while maintaining the ability to safely test obstacle detection and response
Solution Approach 2:
The patent replaces physical/mechanical test environments with a computer-based virtual simulation system. Instead of using physical obstacles and real roads, the system uses digital representations controlled by software, reducing mechanical complexity while enabling safe and repeatable testing
