Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radar continuously detects surroundings and outputs detection results, then detection coverage is improved, but the number of objects that can be processed is limited
Solution Approach 1:
The patent segments the detection data processing by separating encoding (performed by radar for each detected object) from decoding (performed by ECU to combine multiple objects). This allows the radar to continuously detect and encode multiple objects independently, while the ECU decodes and processes them collectively, thereby increasing the number of objects that can be handled without reducing detection coverage.
Solution Approach 2:
The patent introduces a new dimension of data representation by encoding detection results into compressed data structures (including object ID, distance, speed, and angle information in a condensed format). This dimensional transformation allows more object information to be transmitted and processed within the same data bandwidth, effectively increasing productivity while maintaining comprehensive detection coverage.
2Measurement precision
If radar transmits detailed sensing data to central processor, then processing accuracy is improved, but data transmission time increases
Solution Approach 1:
The patent extracts only the essential detection parameters (object ID, distance, speed, angle) and encodes them into compact data structures. By taking out only the necessary information rather than transmitting complete raw sensing data, the system maintains processing accuracy for critical parameters while significantly reducing data transmission time to the central processor.
Solution Approach 2:
The patent changes the parameter representation by encoding detection data into a compressed format with specific parameters (object ID, distance, speed, angle) rather than transmitting full-resolution sensing data. This parameter transformation preserves the essential information needed for accurate processing while reducing data volume and transmission time.
