Engineering Contradiction Analysis
1Length of moving object
If the thickness of vertical supports and transverse supports is reduced to make the curved display device thinner, then the overall device thickness is reduced, but the ability to reduce deformation is lowered and structural stability deteriorates
Solution Approach 1:
The back plate is segmented into a multi-layer structure consisting of a first plate, a second plate, and multiple spacer units distributed between them. This segmentation allows each layer to contribute to structural stability while maintaining overall thinness, as the distributed spacer units provide localized support without requiring thick continuous supports.
Solution Approach 2:
The solution transitions from a single-plane support structure to a three-dimensional multi-layer configuration. By stacking the first plate, second plate, and spacer units in multiple layers, the structure gains enhanced rigidity and deformation resistance in the thickness direction while keeping the overall device thickness controlled.
2Length of moving object
If the thickness of vertical supports and transverse supports is reduced to make the curved display device thinner, then the overall device thickness is reduced, but the curvature control capability deteriorates
Solution Approach 1:
The back plate is divided into multiple layers with spacer units distributed at specific intervals. This segmentation allows precise control of the curvature profile by adjusting the position and spacing of individual spacer units, enabling accurate curvature management even in thinner structures.
Solution Approach 2:
Different regions of the back plate can have different spacer unit configurations, allowing localized optimization of curvature control. The spacer units are distributed non-uniformly to provide enhanced support where curvature control is most critical, while maintaining thinness in other areas.
3Length of moving object
If the thickness of vertical supports and transverse supports is reduced to make the curved display device thinner, then the overall device thickness is reduced, but light leakage caused by compression increases
Solution Approach 1:
The multi-layer structure with distributed spacer units segments the compression forces across multiple interfaces, preventing concentrated compression that would cause light leakage. The spacer units act as discrete support points that distribute mechanical stress evenly, maintaining display uniformity.
Solution Approach 2:
By distributing support functions across multiple layers in the thickness direction, the structure reduces compression-induced deformation in the display plane. The multi-layer configuration provides three-dimensional stress distribution that prevents the compression-related light leakage issues associated with thinner single-layer designs.
