Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar sensors are used to detect spatial relationships, then measurement precision is improved, but blind spots are formed when obstacles block radiowaves
Solution Approach 1:
The patent combines multiple sensing technologies (radar, LiDAR, cameras, ultrasonic sensors) into a unified sensor system. Each sensor type compensates for the weaknesses of others, particularly addressing radar blind spots created by obstacles. The fused data from diverse sensors provides more reliable spatial relationship information than any single sensor could deliver alone.
Solution Approach 2:
The patent introduces wireless communication between vehicles as an intermediary mechanism. When direct sensor detection is blocked by obstacles, vehicles exchange spatial and positional information through communication channels, allowing the system to infer spatial relationships that cannot be directly measured due to blocked line-of-sight.
2Measurement precision
If multiple sensors are deployed to eliminate blind spots, then spatial relationship accuracy is improved, but device complexity increases
Solution Approach 1:
The patent designs a multi-functional sensor system where each sensor serves multiple purposes. For example, the sensor array not only detects spatial relationships but also identifies obstacles, measures distances, and provides data for wireless communication validation. This multi-functionality reduces the need for additional specialized sensors, thereby limiting complexity growth while maintaining high measurement precision.
3Extent of automation
If vehicles operate independently with own sensors, then measurement autonomy is maintained, but spatial relationship reliability decreases in group driving scenarios
Solution Approach 1:
The patent implements feedback mechanisms where vehicles continuously exchange spatial and positional data with group members. Each vehicle's sensor measurements are validated and supplemented by feedback from other vehicles' sensors and communications. This creates a closed-loop system where independent detection capability is maintained but enhanced by continuous inter-vehicle verification, significantly improving spatial relationship reliability in group driving.
