Solution Overview
Problem
Flexible displays in mobile terminals face challenges in being smoothly rolled or unrolled without distortion due to external pressure, requiring complex structural changes to support the display in various shapes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display is made deformable by external force to enable rolling and unrolling, then portability and user convenience are improved, but the display becomes susceptible to distortion and sagging under touch pressure
Solution Approach 1:
The frame is divided into multiple segment plates that can independently move relative to each other. These segmented plates follow the contour of the display when rolled and provide distributed support when unrolled, preventing any single point from bearing excessive load that would cause distortion.
Solution Approach 2:
The frame structure transitions from a static rigid form to a dynamic adaptive structure. The segment plates can change their relative positions and orientations based on whether the display is rolled or unrolled, automatically adjusting to provide optimal support in each state without requiring complex active control mechanisms.
2Adaptability or versatility
If the mobile terminal structure is changed to support a flexible display in bent and curved states, then display flexibility is improved, but the structural complexity increases
Solution Approach 1:
The frame is divided into multiple segment plates that can independently move relative to each other. These segmented plates follow the contour of the display when rolled and provide distributed support when unrolled, preventing any single point from bearing excessive load that would cause distortion.
Solution Approach 2:
The frame uses thin segment plates that can bend and flex to match the display's curved shape when rolled, while still providing sufficient structural support. This approach avoids the need for thick, rigid support structures that would prevent the display from being flexible.
3Reliability
If segment plates are arranged in parallel and in close contact without gaps, then display deformation is prevented under touch input, but the manufacturing precision requirements increase
Solution Approach 1:
The frame structure transitions from a static rigid form to a dynamic adaptive structure. The segment plates can change their relative positions and orientations based on whether the display is rolled or unrolled, automatically adjusting to provide optimal support in each state without requiring complex active control mechanisms.
Solution Approach 2:
The distances and orientations between segment plates are designed to change based on the display's state. When rolled, the plates are positioned to follow the curved contour; when unrolled, they adjust to provide flat support. This dynamic parameter adjustment allows for reliable support while accommodating manufacturing tolerances.
