Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensors are dispersed over a vehicle, then installation flexibility is improved, but information collection efficiency deteriorates
Solution Approach 1:
The patent combines multiple sensors (radar, lidar, camera, infrared sensor) into a single integrated sensor cluster device mounted on the vehicle. This merging approach improves information collection efficiency by consolidating data acquisition from multiple sensors into one unified system, while still maintaining installation flexibility through the modular design of the sensor cluster unit that can be mounted at optimal locations on the vehicle.
2Ease of operation
If sensors are dispersed over a vehicle, then installation flexibility is improved, but arithmetic operation load deteriorates
Solution Approach 1:
The patent integrates multiple sensors into a single sensor cluster device with unified processing capabilities. This reduces the overall arithmetic operation load by consolidating data processing tasks within the integrated device rather than requiring separate processing systems for each dispersed sensor, thereby simplifying the computational architecture while maintaining installation flexibility.
3Productivity
If sensors are integrated into a single device, then information collection efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides the integrated sensor system into modular functional components (radar sensor unit, lidar sensor unit, camera sensor unit, infrared sensor unit) that are physically integrated but can be independently managed. This segmentation approach allows for efficient information collection from multiple sensors while reducing overall device complexity through modular design, enabling easier maintenance, testing, and configuration of individual sensor modules within the integrated cluster.
4Measurement precision
If sensors are integrated into a single device, then accurate information acquisition is improved, but installation complexity increases
Solution Approach 1:
The patent employs a modular sensor cluster design where multiple sensor types are integrated into a single device with standardized mounting interfaces. This segmentation into functional modules maintains accurate information acquisition capabilities while reducing installation complexity through pre-integrated wiring, unified mounting structures, and standardized connection protocols that simplify the installation process compared to installing multiple separate sensor systems.
