Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If object detection is performed using an external processor with heavy load calculation, then object detection capability is achieved, but processing delay increases
Solution Approach 1:
The patent segments the object detection system into two parts: a sensor device that performs preliminary detection and classification of objects, and an external processor that handles only confirmed target objects. This segmentation reduces the calculation load on the external processor and minimizes processing delays while maintaining detection accuracy.
Solution Approach 2:
The sensor device performs preliminary object detection and classification before transmitting data to the external processor. By pre-processing the detection signals and identifying potential targets in advance, the system reduces the amount of data requiring heavy calculation and accelerates the overall detection process.
2Speed
If frame rate is maintained at high level for all detection scenarios, then detection responsiveness is improved, but resource consumption increases
Solution Approach 1:
The patent implements dynamic frame rate adjustment based on detection scenarios. The sensor device adjusts the frame rate of detection signals according to the presence and characteristics of detected objects, maintaining high responsiveness when needed while reducing resource consumption during normal operation or when no targets are present.
Solution Approach 2:
The system changes the frame rate parameter dynamically based on detection results and operational requirements. By adjusting this key parameter according to the situation, the system optimizes the balance between detection responsiveness and resource efficiency without compromising the ability to detect and respond to important events.
