Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a driver is bonded to a side surface of a display panel by a bonding device, then the bonding process can be performed, but it is difficult to adjust or control the horizontal level of the side surface of the display panel
Solution Approach 1:
The patent applies curvature by designing the supporter with a recess portion having a first radius of curvature and the first support surface with a curved surface having a second radius of curvature. These curved surfaces work together to enable precise adjustment of the horizontal level of the display panel side surface, allowing the bonding device to achieve parallel alignment with the bonding head while maintaining a manageable device structure.
2Reliability
If the side surface of the display panel is not parallel to the bonding head, then the bonding process cannot be performed uniformly, but adjusting the horizontal level increases device complexity
Solution Approach 1:
The curved surfaces with specific radii of curvature in the stage and supporter enable precise horizontal level adjustment, ensuring the display panel side surface becomes parallel to the bonding head. This curvature-based design allows for reliable uniform bonding while keeping the structural complexity manageable through geometric optimization.
Solution Approach 2:
The patent changes geometric parameters by designing specific radius of curvature values for the recess portion and curved surface. By optimizing these curvature parameters, the device achieves the ability to adjust horizontal level precisely, ensuring parallel alignment between the display panel side surface and bonding head, thereby improving bonding quality without excessive structural complexity.
3Ease of manufacture
If the horizontal level of the side surface cannot be controlled, then bonding defects increase, but adding adjustment mechanisms increases device complexity
Solution Approach 1:
The curved surfaces with optimized radii of curvature provide an elegant solution for controlling horizontal level. This geometric approach enables uniform bonding process by ensuring proper parallel alignment, while avoiding the need for complex mechanical adjustment mechanisms, thus maintaining ease of manufacture with reasonable device complexity.
