Segmented Support Plate for Flexible Sliding Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in maintaining device reliability and mechanical stability, particularly when subjected to bending, folding, or sliding operations, which can lead to deformation and reduced functionality.
Innovation Solution
The display device incorporates a support plate with a grid pattern portion and segment bodies that include protrusion areas connected by connection portions, providing structural support and preventing deformation during bending or sliding operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support structure is used to maintain mechanical stability, then structural integrity is improved, but flexibility for bending and folding operations deteriorates
Solution Approach 1:
The support plate is divided into multiple segments separated by slits, allowing each segment to move independently during bending and folding operations while maintaining overall structural support. The segment bodies are further divided into protrusion areas and support areas connected by connection portions, enabling localized flexibility while preserving global mechanical stability.
Solution Approach 2:
The support structure transitions from a static rigid plate to a dynamic system where segments can slide relative to each other along the slits. The connection portions between segment bodies are designed to allow controlled deformation during bending operations, providing adaptability while maintaining structural integrity.
2Stability of the object's composition
If the support plate is made continuous and rigid, then structural integrity is improved, but deformation during sliding operations increases
Solution Approach 1:
The support plate is segmented into multiple sections by slits, allowing each segment to maintain its shape independently during sliding operations. The segment bodies with connection portions further divide the structure into manageable units that can accommodate sliding-induced stresses without overall deformation.
Solution Approach 2:
Different portions of the support structure have different properties: the slits provide flexibility in specific locations to prevent deformation, while the segment bodies and connection portions maintain structural integrity in other areas. This localized differentiation allows the structure to resist deformation during sliding while maintaining overall stability.
3Adaptability or versatility
If segment bodies are spaced apart to allow flexibility, then adaptability for bending is improved, but mechanical stability deteriorates
Solution Approach 1:
The connection portions act as intermediaries between the spaced-apart segment bodies, providing both flexibility for bending and mechanical stability. These connection structures allow the segments to move relative to each other during bending operations while maintaining sufficient structural support through their integral connection design.
