Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If single-direction positioning and manual adjustment are used, then the device complexity is low, but the positioning precision is insufficient and requires experienced personnel
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated optical positioning system. The optical module captures images of the probe card, and the computer control interface automatically calculates positioning coordinates, eliminating the need for manual visual inspection and adjustment by experienced personnel.
Solution Approach 2:
The system performs self-positioning by automatically capturing images, calculating coordinates, and adjusting the grinding head position without human intervention. The computer control interface autonomously processes the optical data and controls the displacement device to achieve precise positioning.
2Productivity
If manual adjustment and repeated tests are used to achieve grinding standards, then the manufacturing precision can be maintained, but the productivity is reduced
Solution Approach 1:
The system performs preliminary positioning before grinding by capturing images and calculating precise coordinates in advance. This preliminary optical positioning ensures that the grinding head is correctly positioned before the grinding process begins, eliminating the need for repeated tests and adjustments during grinding.
Solution Approach 2:
The optical module provides feedback by capturing images of the probe card, which are then processed by the computer control interface to determine precise positioning coordinates. This feedback mechanism ensures accurate positioning before grinding, maintaining manufacturing precision while improving productivity.
3Ease of manufacture
If sandpaper is used for grinding, then the ease of manufacture is high, but the sandpaper needs frequent replacement increasing loss of time and cost
Solution Approach 1:
The patent acknowledges that sandpaper is a disposable consumable item. While sandpaper itself remains cheap and easy to manufacture, the system minimizes its frequent replacement by optimizing the grinding process through precise automated positioning, thereby reducing waste and replacement frequency.
4Loss of time
If manual adjustment of carrier height is used, then the device complexity is low, but the loss of time and cost is high
Solution Approach 1:
The patent replaces manual mechanical adjustment of carrier height with an automated optical measurement system. The optical module captures images to determine the carrier height, and the computer control interface automatically calculates the required adjustment, eliminating time-consuming manual measurement and adjustment.
Solution Approach 2:
The system performs self-measurement and self-adjustment of carrier height. The optical module automatically measures the carrier position, and the displacement device automatically adjusts the grinding head height based on computer-calculated coordinates, without requiring manual intervention.
