Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment method is used, then operator experience can be utilized, but adjustment time increases and error rate becomes high
Solution Approach 1:
The patent replaces manual visual inspection and mechanical adjustment with an automated optical measurement system. A laser sensor automatically measures the distance between the pick-and-place mechanism and reference plane at multiple positions, eliminating the need for operator visual assessment and manual adjustment operations.
Solution Approach 2:
The system performs self-adjustment by automatically calculating compensation angles based on measured data and executing positional corrections without operator intervention. The control system processes measurement results and autonomously adjusts the pick-and-place mechanism to achieve accurate flatness alignment.
