Engineering Contradiction Analysis
1Measurement precision
If users check circuit board files through computer or printing files to find correct pins, then they can obtain pin location information, but the process becomes time-consuming due to complex pin layouts and densities
Solution Approach 1:
The patent replaces the manual mechanical process of visually searching through pin layouts with an automated image recognition system. The camera captures images of the circuit board, and the processing circuit automatically identifies pin locations and matches them with file information, eliminating the need for users to manually compare physical layouts with documentation.
Solution Approach 2:
The patent creates a digital copy of the circuit board's physical appearance through camera imaging. This digital representation is then processed to extract pin location information, allowing the system to reference and compare with file data without requiring physical manipulation or visual inspection of the actual circuit board.
2Ease of operation
If users manually compare circuit board with corresponding files according to layout distribution, pin density, and pin quantity, then they can identify correct pins, but the process becomes complex and time-consuming
Solution Approach 1:
The patent replaces complex manual analysis of pin layouts with automated image processing. The processing circuit uses algorithms to automatically detect pin positions, count pin quantities, and analyze layout patterns from camera images, eliminating the need for users to manually perform these complex comparison tasks.
Solution Approach 2:
The system performs self-service by automatically analyzing the circuit board images and extracting pin information without requiring user intervention in the analysis process. The processing circuit independently compares the captured images with stored file data and provides pin location identification results automatically.
