Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual re-adjustment of grinding wheel position is performed after replacement, then positioning accuracy can be achieved, but processing time increases and efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated optical measurement system. A laser displacement sensor automatically measures the positional shift of the grinding wheel after replacement, and a control unit calculates and applies the correction amount, eliminating the need for manual testing and adjustment while maintaining positioning accuracy.
Solution Approach 2:
The system performs self-positioning by automatically detecting the grinding wheel's actual position through laser measurement, calculating the deviation from the reference position, and applying corrective movement without requiring external manual intervention. This self-service mechanism resolves the contradiction by making the system both accurate and efficient.
2Manufacturing precision
If manual testing of processed shape is performed to re-adjust grinding wheel position, then positioning accuracy improves, but time consumption increases
Solution Approach 1:
The patent performs preliminary measurement of the grinding wheel position immediately after replacement, before actual processing begins. The laser displacement sensor measures the wheel's position, the control unit calculates the correction amount, and the system applies the correction in advance, eliminating the need for time-consuming manual testing of processed shapes during production.
Solution Approach 2:
The manual visual inspection and physical testing of processed shapes is replaced with an automated laser measurement system that quickly and accurately determines positional shifts, significantly reducing the time required while maintaining or improving positioning precision.
3Productivity
If automated measurement and correction of positional shift is implemented, then processing efficiency increases, but device complexity increases
Solution Approach 1:
The patent introduces a laser displacement sensor as an intermediary measurement device that non-contactly measures the grinding wheel's position. This intermediary enables automated detection without requiring complex direct measurement mechanisms, achieving high efficiency while keeping the added complexity manageable through the use of established sensor technology.

AI summary
A processing apparatus for brittle plate includes a table which holds a brittle plate, a processing head having a processing wheel for processing an outer peripheral edge of the brittle plate held by the table, a measuring portion which measures a positional shift amount Δ in an axis direction of the processing wheel with respect to the brittle plate, and a control portion which corrects a positional shift in a Z-axis direction of the processing wheel on the basis of a positional shift amount Δ in the axis direction of the processing wheel measured by the measuring portion and causes the processing wheel whose positional shift was corrected to process the outer peripheral edge of the brittle plate. The processing apparatus and its method can reduce time and labor of manually positioning of a processing wheel to the brittle plate after processing wheel replacement.
