Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If vacuum adsorption or mold pressing is used to form curved display panels, then curved surfaces can be formed, but uncontrollable factors cause redundant parts and attachment wrinkles that damage flexible panels
Solution Approach 1:
The profiling component is designed with movable thimbles that can dynamically adjust their positions and heights. The thimbles are configured to move relative to each other, with some thimbles having greater movement ranges than others, allowing the system to adapt to different curvature requirements and prevent wrinkle formation during the curved surface formation process
Solution Approach 2:
The system changes physical parameters by adjusting the heights and positions of individual thimbles. By varying the movement ranges of different thimbles and controlling their relative positions, the system can precisely control the forming process parameters to eliminate redundant parts and attachment wrinkles
2Ease of manufacture
If flexible panels are attached to carrier films and formed by vacuum adsorption, then curved panels can be manufactured, but attachment wrinkles occur reducing manufacturing precision
Solution Approach 1:
The profiling component is segmented into multiple independent thimbles distributed across the framework. Each thimble can be independently adjusted and controlled, allowing precise local control over the forming process. This segmentation enables different regions of the flexible panel to be formed with different curvature parameters, achieving the desired four-sided curved surface with high precision
Solution Approach 2:
Different thimbles are configured with different movement ranges and positions to create local variations in the forming process. The thimbles in different regions can move by different amounts, allowing the system to create different curvature radii and angles in different areas of the display panel, achieving the required local fitting effects

AI summary
A profiling device, a manufacturing method of a display panel, and the display panel are disclosed. Wherein, the profiling component includes a first surface, and the first surface includes a first region and a second region. When the profiling component is in a first state, the first surface is used to attach to a display component. When the profiling component is in a second state, a part of the first surface corresponding to the first region is arc-shaped and higher than a part of the first surface corresponding to the second region to allow a position of the display component corresponding to the second region to form a curved structure.
