Solution Overview
Problem
Current foldable display devices lack an inner space for additional structures, limiting their functionality and user experience.
Innovation Solution
A foldable display device design that includes a flexible display module with non-foldable and foldable portions, supported by metal plates and hinges, allowing for a case structure that provides a space for additional components when folded or unfolded, enabling the integration of extra features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional rigid case structure is used to protect the display module, then protection strength is improved, but the device cannot provide additional functional space and loses flexibility
Solution Approach 1:
The case is divided into multiple segments: a rigid outer case for protection, and an inner flexible case that can deform. This segmentation allows the outer case to provide strength while the inner flexible case creates variable space for additional functions.
Solution Approach 2:
The inner case is designed to be flexible and dynamic, able to change its shape and volume in response to the folding state of the display module. This dynamic behavior enables the creation of additional functional space that adapts to different device configurations.
2Adaptability or versatility
If the display module is made fully flexible to enable folding, then adaptability is improved, but structural stability and protection deteriorate
Solution Approach 1:
The display module is segmented into flexible display regions and rigid support regions. The rigid support regions maintain structural stability while the flexible regions enable folding motion.
Solution Approach 2:
The device uses composite construction combining flexible display materials with rigid support structures and protective cases. This composite approach maintains structural integrity while enabling flexible folding capability.
3Adaptability or versatility
If additional structures are added to enhance functionality, then adaptability is improved, but device complexity increases
Solution Approach 1:
The flexible inner case serves multiple functions: it provides structural support, enables the creation of additional functional space, and accommodates various additional components. This multi-functionality reduces the need for separate dedicated structures.
Solution Approach 2:
Additional functional structures are nested within the flexible inner case, which itself is nested within the rigid outer case. This nested arrangement consolidates multiple functions into a compact integrated structure rather than adding separate external components.
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 design allows for the incorporation of additional structures within the display device, enhancing its functionality and user experience by providing a flexible and robust mechanism for folding and unfolding without damaging the foldable portion.
Implementation Method 1
a first hinge rotatably connected to the coupling cover and that includes a first fixed support portion that supports the first fixed portion and a first portion that supports the second rotatable portion or the first rotatable portion according to a rotation of the first cover
Implementation Method 2
a first metal plate disposed between the flexible display module and the case and that includes a first fixed portion that supports the first non-foldable portion and a first rotatable portion that supports the foldable portion adjacent to the first non-foldable portion
Implementation Method 3
a first portion of the first hinge further includes a first non-fixed support portion spaced apart from the first fixed support portion and that supports the second rotatable portion when the flexible display module is unfolded
