Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a bending head is used to bend the display device, then the display device can be bent into desired shapes, but the bending process becomes unstable and inaccurate
Solution Approach 1:
The patent employs distance measurement sensors to continuously monitor the positions and slopes of both the stage and bending head. The control unit receives this feedback information and automatically adjusts the positions and slopes to maintain them within predetermined tolerance ranges, ensuring stable and accurate bending processes
Solution Approach 2:
The patent replaces manual or simple mechanical positioning with an automated control system that uses distance measurement sensors and a control unit to precisely adjust and maintain the positions and slopes of the stage and bending head, substituting mechanical intuition with automated measurement and control
2Device complexity
If manual positioning of the stage and bending head is used, then the apparatus structure remains simple, but the alignment and bending accuracy deteriorates
Solution Approach 1:
Distance measurement sensors are installed to automatically measure and provide feedback on the positions and slopes of the stage and bending head. The control unit processes this feedback information and makes automatic adjustments, replacing manual positioning with automated feedback control to achieve high alignment precision
Solution Approach 2:
The system performs self-adjustment through automated measurement and control. The distance measurement sensors continuously monitor the positions and slopes, and the control unit automatically corrects any deviations without requiring manual intervention, enabling the apparatus to maintain high precision independently
