Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If general evaluation methods are used to assess unmanned vehicle intelligence level, then the evaluation process is simple, but the measurement precision and ability to identify specific performance defects is low
Solution Approach 1:
The patent segments the evaluation system into multiple indicator combinations, each targeting specific coping capabilities (braking, turning, acceleration, etc.). Instead of a single general evaluation, the system divides assessment into focused modules that measure specific performance aspects independently, enabling precise identification of defect areas while maintaining manageable complexity through modular design.
Solution Approach 2:
The patent changes evaluation parameters by introducing multiple indicator combinations with different expected value ranges tailored to specific driving scenarios. Each indicator combination adjusts measurement parameters (speed, acceleration, braking force) according to scenario requirements, transforming a generic evaluation into a parameter-adaptive system that achieves high precision without proportional complexity increase.
2Adaptability or versatility
If targeted evaluation of specific driving scenarios is implemented, then the pertinence and usefulness of evaluation results improve, but the device complexity and number of indicator combinations increase
Solution Approach 1:
The patent applies preliminary action by pre-establishing multiple indicator combinations before actual evaluation, each configured for specific driving scenarios (braking, turning, acceleration). This preparation phase creates ready-to-use evaluation templates that can be quickly selected and applied during testing, reducing real-time complexity while maintaining high adaptability to different scenarios.
Solution Approach 2:
The patent creates a universal evaluation framework where indicator combinations serve multiple functions: they can be selected and applied to different driving scenarios, reused across various testing phases, and adapted to evaluate different vehicle types. This multi-functionality allows the system to handle diverse evaluation needs without proportionally increasing complexity, as the same framework structure serves multiple purposes.
