Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional sensor elements are used for object detection and classification, then measurement precision may be improved, but device complexity increases
Solution Approach 1:
The radar sensor unit is designed to perform multiple functions including object detection, object classification, depth determination, and wall type classification using a single sensor system, eliminating the need for multiple specialized sensor elements while maintaining comprehensive diagnostic capabilities
Solution Approach 2:
The diagnostic module analyzes different parameters from the radar data (signal strength, time of flight, frequency characteristics) to extract multiple types of information including object presence, classification, depth, and wall type, achieving comprehensive detection through parameter analysis rather than multiple sensors
2Measurement precision
If additional sensor information is integrated for object classification, then object type identification accuracy may improve, but the diagnostic process becomes more complex
Solution Approach 1:
The patent extracts and analyzes specific characteristics from the radar data signals (such as reflection patterns, signal strength variations, and time delays) to classify objects and determine wall types, achieving accurate classification by focusing on key extracted features rather than processing all possible sensor data
Solution Approach 2:
The diagnostic module serves as an intermediary that processes radar data to determine wall type first, then uses this wall type information to interpret object characteristics, creating a hierarchical processing approach that simplifies the overall classification task by breaking it into manageable steps
3Adaptability or versatility
If multiple sensor types are used for comprehensive wall diagnosis, then diagnostic completeness improves, but ease of operation decreases
Solution Approach 1:
The patent combines object detection, object classification, depth determination, and wall type classification functions into a single integrated diagnostic module that processes radar data from one sensor unit, providing comprehensive wall diagnosis through a unified system that maintains operational simplicity
