Foldable Display Case With Elastic Mover For Wrinkle-Free Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable display devices face challenges in smoothly folding and unfolding without causing image distortion or damage, particularly due to the stress generated during folding and potential external impacts when the display is not properly secured.
Innovation Solution
A case design incorporating coiled compression or tension springs with stoppers and fasteners that support the foldable display panel, allowing for elastic restitution forces to guide the panel's folding and unfolding, ensuring a flat and wrinkle-free surface while protecting the display from stress and external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the foldable display panel is supported by a case without elastic restraint, then the structure is simple, but the display panel cannot be smoothly folded or unfolded and is susceptible to external impacts
Solution Approach 1:
The elastic body acts as an intermediary between the display panel and the case, providing flexible restraint forces that protect the display panel during folding and unfolding while absorbing external impacts, thus enhancing reliability without requiring complex rigid support structures
Solution Approach 2:
The case structure incorporates movable components including the elastic body that can dynamically adjust during folding and unfolding operations, allowing the case to adapt to different states of the display panel while maintaining protection and support
2Manufacturing precision
If the foldable display panel is restrained during folding, then image quality is maintained, but the folding operation becomes complex
Solution Approach 1:
The elastic body serves as a mediator that applies gentle restraint forces to maintain the flatness of the display panel during folding and unfolding, ensuring image quality without requiring complex rigid constraint mechanisms
Solution Approach 2:
The elastic body changes its physical state (compression/expansion) during folding operations, dynamically adjusting its restraint force to maintain panel flatness while accommodating the folding motion, thus achieving precision without complex mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The case design effectively supports the foldable display panel, maintaining image quality by preventing wrinkles and damage during folding and unfolding, while also ensuring the panel remains flat and protected from external impacts.
Implementation Method 1
the mover has the elastic restitution force, and thus the end of the foldable display panel is slid in the direction of one end of the first main body

AI summary
A case for supporting a foldable display panel includes a first main body located to correspond to a first area of the foldable display panel; a second main body located to adjoin the first main body and correspond to a second area of the foldable display panel, and folded in a direction of the first main body so that the second area of the foldable display panel faces the first area; and a mover, responsive to an elastic restitution force, located within at least the first main body to be supported by a rear surface of the foldable display panel, at least one of the first area and the second area of the foldable display panel being slidable in conjunction with the mover in a direction of at least one an end of the foldable display panel.
