Curved Sliding Display Support Structure for Boundary Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slidable display devices experience defects due to bending at the boundary between areas, particularly when the second area is lifted, leading to potential damage and external light reflection issues.
Innovation Solution
A display device design incorporating a first and second area with varying curvatures and rigidity, supported by a plurality of supporting elements and plates with specific contact and separation distances, and a guide unit to prevent entanglement and enhance durability and reduce light reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the second area is lifted to enable sliding, then the display device can be compacted, but bending occurs at the boundary between areas causing defects
Solution Approach 1:
The patent applies local quality by differentiating the structural properties at different locations. The boundary region between the first and second areas is given special structural treatment with support plates and curved surface designs, while other regions maintain different characteristics. This localized structural enhancement prevents bending defects at the boundary while preserving the overall sliding functionality.
Solution Approach 2:
The patent implements beforehand cushioning by pre-configuring support plates and curved surface structures at the boundary region before the lifting operation occurs. These pre-arranged structural elements provide mechanical support and distribute stresses to prevent bending defects from occurring during the sliding and lifting operations.
2Area of stationary object
If the display area is increased through sliding, then the display capability is improved, but external light reflection increases
Solution Approach 1:
The patent applies spheroidality by designing the support plate with a curved surface that follows the curvature of the display module. This curved surface structure helps to redirect external light away from the display area, reducing reflection effects while maintaining the expanded display capability through the sliding mechanism.
3Reliability
If supporting elements are added to prevent bending, then boundary integrity is improved, but device complexity increases
Solution Approach 1:
The patent applies merging by integrating the support plates with the existing housing structure and display module assembly. The support plates are positioned to work in conjunction with the curved surface of the display module, combining multiple functions (structural support, bending prevention, and light reflection reduction) into a unified structural arrangement rather than adding separate independent components.
