Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection and alignment of pogo pins is used, then the device complexity is low, but the productivity is low and measurement precision is insufficient
Solution Approach 1:
The patent replaces manual mechanical alignment and inspection with an automated vision-based system. A vision module captures images of the pogo pin, and image processing algorithms automatically determine the pin's posture and alignment status, eliminating the need for manual mechanical adjustment and inspection operations.
Solution Approach 2:
The system enables self-service alignment by automatically detecting the pogo pin's position and orientation through vision modules, then autonomously adjusting the seating portion to achieve proper alignment without human intervention. The image processing system self-determines alignment status and controls the adjustment mechanism.
2Measurement precision
If manual alignment of pogo pin is used, then the device complexity is low, but the measurement precision is insufficient
Solution Approach 1:
The patent replaces manual visual estimation and mechanical alignment with an automated vision-based measurement system. Vision modules capture high-resolution images, and image processing algorithms precisely calculate the pogo pin's posture and alignment, achieving superior measurement precision without manual intervention.
Solution Approach 2:
The system creates an optical copy (image) of the pogo pin instead of relying on direct manual measurement. The vision module captures the pin's appearance, and image processing algorithms analyze the captured image to determine alignment status, allowing for precise non-contact measurement.
3Productivity
If manual inspection of pogo pin appearance is used, then the device complexity is low, but the productivity is low
Solution Approach 1:
The vision module continuously captures images of the pogo pin at multiple positions and angles without interruption. The image processing system continuously analyzes each image to detect defects, enabling continuous inspection operation that significantly increases productivity compared to manual inspection.
Solution Approach 2:
The patent replaces manual visual inspection with an automated vision-based inspection system. The vision module captures images and the image processing system automatically analyzes them for defects, eliminating the need for manual inspection operations and dramatically improving inspection speed.
