Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used to gather environmental information for complex automation tasks, then the accuracy and completeness of detection is improved, but the complexity of processing sensor information and identifying errors increases
Solution Approach 1:
The patent combines data from multiple sensors (LiDAR, optical sensors, cameras) into a unified detection report through data fusion. This merging approach consolidates multiple sensor inputs into a single coherent representation of the environment, improving detection accuracy while managing processing complexity through integrated processing.
Solution Approach 2:
The computing device acts as an intermediary that receives raw data from multiple sensors, processes and fuses this information, and generates a unified detection report. This intermediary processing layer manages the complexity of handling multiple sensor types by standardizing their outputs into a common format that can be used for automation decisions.
2Adaptability or versatility
If multiple sensors are deployed to enable complex automation activities, then the capability to understand the environment is improved, but the difficulty of rendering a unitary view of the environment increases
Solution Approach 1:
The system merges fields of view from multiple sensors positioned at different locations on the vehicle into a single unified detection report. This combining approach creates a comprehensive environmental model that captures information from all sensor perspectives, enabling the vehicle to understand its environment from multiple angles simultaneously.
Solution Approach 2:
The unified detection report serves as a universal data structure that integrates information from various sensor types (LiDAR, optical, camera) and positions. This multi-functional report format can represent diverse sensor inputs in a standardized way, making it applicable for various automation tasks regardless of the specific sensor configuration.
3Device complexity
If a single sensor is used for simple automation tasks, then the system simplicity is maintained, but the efficiency and safety of complex tasks are insufficient
Solution Approach 1:
The system segments automation tasks by sensor type and function, with different sensors (LiDAR for distance, optical sensors for color, cameras for visual recognition) handling specific aspects of environmental perception. This segmentation allows each sensor to optimize for its specialized function while the computing device integrates their outputs, achieving both simplicity in individual sensor design and high efficiency in overall system performance.

AI summary
An object classification system for a vehicle detects, with a computing device, a first field of view with a first sensor and a second field of view with a second sensor, each sensor mounted on the vehicle.
