Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flat panel display device is pre-bent to have a certain degree of curvature through a manufacturing process and then fixed, then the display device provides a curved shape for better viewing effect, but the curvature becomes constant and cannot achieve rotational display
Solution Approach 1:
The patent applies the dynamics principle by transforming the static curved display structure into a dynamic one. The display device incorporates a rolling mechanism with driving wheels that can rotate the flexible display panel between different curvature states and orientations. This allows the display to dynamically change from a fixed curved shape to a rotatable structure that can achieve rotational display effects, thereby resolving the contradiction between maintaining a curved shape and enabling rotational capability.
2Ease of manufacture
If a curved display device is manufactured with a fixed curvature through pre-bending and fixing, then the structure is stable and simple to manufacture, but it cannot satisfy diversified user demands for different viewing preferences
Solution Approach 1:
The patent maintains manufacturing simplicity by using a flexible display panel that can be bent and then incorporates a rolling mechanism with driving wheels. This dynamic structure allows the display to be manufactured in a relatively simple manner while enabling diversified viewing options through rotational movement, resolving the contradiction between ease of manufacture and adaptability to different user preferences.
Solution Approach 2:
The patent applies parameter changes by enabling the display device to change its curvature radius and orientation angles through the rolling mechanism. The flexible display panel can be rolled to different degrees, changing physical parameters such as curvature radius and viewing angle, thereby providing diversified viewing options without complicating the manufacturing process.
3Adaptability or versatility
If the flexible display is supported by a rolling mechanism with adjustable gear distance, then the curvature can be adjusted according to actual needs, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by incorporating adjustable gear distance in the rolling mechanism. This allows the curvature radius of the flexible display to be adjusted according to actual needs by changing the distance between driving gears. While this increases device complexity, it provides the necessary adaptability for different curvature requirements.
Solution Approach 2:
The rolling mechanism with adjustable gear distance serves multiple functions: it enables curvature adjustment, achieves rotational display, and provides different viewing angles. This multi-functionality justifies the increased device complexity by consolidating multiple capabilities into a single integrated mechanism.
