Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are disposed at different positions to detect objects outside the vehicle, then the detection coverage is improved, but the synchronization of detection data becomes difficult
Solution Approach 1:
A signal processing unit is introduced as an intermediary component to receive detection data from multiple sensors disposed at different positions and synchronize their outputs. This mediator coordinates the timing of detection data from cameras, lidars, radars, and other sensors, enabling them to function as a unified system while maintaining their individual detection coverage advantages.
2Reliability
If sensors are synchronized to output detection data at the same timing, then the object detection performance is improved, but the system complexity increases
Solution Approach 1:
Multiple sensors and their signal processing functions are merged into an integrated sensor integration module. The signal processing unit combines detection data from various sensors (camera, lidar, radar, ultrasonic sensor, infrared sensor) and synchronizes their outputs, achieving coordinated object detection while consolidating the system architecture to manage complexity.
3Ease of operation
If multiple sensors are integrated in one module, then the synchronization control is simplified, but the device complexity increases
Solution Approach 1:
The sensor integration module is designed with universal functionality to accommodate multiple types of sensors (camera, lidar, radar, ultrasonic sensor, infrared sensor) within a single module. The signal processing unit provides multi-functional capabilities to process and synchronize detection data from all these different sensor types, simplifying synchronization control while managing the inherent complexity through standardized interfaces.
