Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a flexible screen adopts a sliding-stretching form to enable portable large screen, then the display area and portability are improved, but the stretching speed becomes slow causing long waiting time for users
Solution Approach 1:
The support frame is divided into multiple sliding support members (first sliding support member and second sliding support member) that can move relative to each other. This segmentation allows the screen to be stretched through coordinated movement of multiple components rather than a single stretching action, improving the stretching speed and reducing waiting time while maintaining the large display area capability
Solution Approach 2:
The patent introduces a driving mechanism that dynamically controls the movement of sliding support members along guiding rails. This dynamic system enables the support members to move at controlled speeds and coordinates, transforming the static stretching process into a dynamic, adjustable operation that can be optimized for speed to reduce user waiting time
2Productivity
If the first sliding support member and the second sliding support member move relatively to each other to increase stretching speed, then the unfolding speed is improved, but the complexity of the driving mechanism increases
Solution Approach 1:
The driving mechanism integrates multiple functions into a unified system: the first driving mechanism simultaneously controls the movement of both the first sliding support member along its guiding rail and the second sliding support member along its guiding rail. This merging of control functions into a single coordinated system achieves fast unfolding speed while avoiding the need for separate complex control systems for each component
3Productivity
If the flexible screen is stretched quickly to reduce waiting time, then the productivity is improved, but the risk of tearing or wrinkling the screen increases
Solution Approach 1:
The guiding rails provide geometric constraints that ensure the sliding support members move along predetermined safe paths. This built-in feedback mechanism through the rail geometry automatically controls the movement trajectory and speed distribution, preventing excessive stress concentration on any part of the flexible screen during rapid stretching, thus maintaining screen integrity while achieving high productivity

AI summary
A support structural member and a display device. The support structural member includes: a support frame, having a screen body support surface, in which the support frame includes a first sliding support member and a second sliding support member arranged opposite to each other, and the first sliding support member and the second sliding support member are movably connected in a first direction; a driving portion, including a first driving mechanism, in which the first driving mechanism is configured to drive the first sliding support member and the second sliding support member to move relatively to each other in the first direction to drive the first sliding support member and the second sliding support member approach to or far away from each other.
