Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sensor systems and processing methods are used, then the system structure is simpler, but the object detection accuracy and classification capability deteriorate in adverse weather conditions
Solution Approach 1:
The patent combines multiple sensor types (radar, camera, lidar) into a unified sensor fusion system that integrates their data streams. This merging allows the system to overcome the limitations of individual sensors in adverse weather conditions by compensating for their respective weaknesses through complementary data from other sensors.
Solution Approach 2:
The radar system is designed with multi-functional capabilities including detection, classification, tracking, and environmental interpretation. The reinforcement learning engine provides universal intelligence that can adapt to various weather conditions and object types, making the system versatile across different operating scenarios.
2Measurement precision
If comprehensive environmental monitoring is implemented, then the object classification capability improves, but the processing time increases
Solution Approach 1:
The system performs preliminary processing of sensor data including feature extraction, target detection, and initial classification before full analysis. The reinforcement learning engine learns from historical data to predict likely object types and scenarios, allowing the system to prioritize processing of critical information and reduce overall processing time.
Solution Approach 2:
The reinforcement learning engine continuously learns and adapts from the data it processes, improving its classification accuracy over time without requiring additional processing resources. The system optimizes its own performance by identifying patterns and making decisions that reduce the computational burden on the processing system.
3Speed
If rapid response to environmental changes is required, then the response speed improves, but the detection accuracy may deteriorate due to reduced processing time
Solution Approach 1:
The system implements periodic scanning and updating of the environment at different frequencies based on the dynamic state. Critical areas and moving objects receive more frequent updates, while stable environments are monitored at lower frequencies. This periodic action allows rapid response to changes while maintaining accuracy through sufficient sampling.
Solution Approach 2:
The system dynamically adjusts its processing priorities and resource allocation based on the current environmental state. When rapid changes are detected, the system shifts to high-speed processing modes with simplified algorithms for immediate response. When the environment is stable, more comprehensive analysis can be performed to maintain high detection accuracy.
