Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a conventional inspection device structure is used, then the device is simple in structure, but the device cannot quickly and accurately move and contact the product for inspection
Solution Approach 1:
The inspection device employs a dynamic mechanism where the support can rotate about a vertical axis and the inspection terminal can move in multiple directions (horizontal, vertical, and angular). This dynamic structure allows the device to quickly adapt its position and orientation to contact the product for inspection, thereby improving movement speed while managing structural complexity through functional integration.
2Reliability
If the inspection device contacts the product, then defect detection is possible, but the reliability of contact and pressure application is inconsistent
Solution Approach 1:
The inspection terminal is designed with dynamic adjustment capabilities including vertical movement, horizontal movement, and angular adjustment. This allows the terminal to adapt to variations in product position and maintain consistent contact pressure, thereby improving contact reliability while ensuring uniform pressure application for accurate defect detection.
Solution Approach 2:
The device incorporates adjustable parameters such as the vertical position of the support, the angular position of the inspection terminal, and the contact pressure. By dynamically changing these parameters, the system can optimize contact conditions for each inspection scenario, ensuring both reliability and measurement precision.
3Productivity
If the inspection device moves quickly, then productivity increases, but the accuracy of contact and inspection may decrease
Solution Approach 1:
The inspection device uses dynamic mechanisms that enable quick positioning followed by precise adjustment. The support can rapidly rotate to different positions, and the inspection terminal can quickly move into contact with the product. After contact, the system can make fine adjustments to ensure accurate inspection, thereby maintaining both high productivity and inspection accuracy.
