Elastic Sheet Support for Foldable Terminal Screen Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible screens in foldable terminals experience a poor user press experience when unfolded due to the middle portion hanging in the air without support, causing a lack of connection to internal structural members.
Innovation Solution
Incorporating an elastic sheet within the foldable terminal's housing, which protrudes differently when the terminal is folded versus unfolded, providing support to the flexible screen and maintaining the screen's flatness by deforming to support the screen's inner side when unfolded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an accommodation space is reserved at the inner side of the terminal product to facilitate folding of the flexible screen, then the flexible screen can be conveniently folded and received in the accommodation space, but the middle portion of the flexible screen hangs in the air when the terminal product is unfolded and is not supported by internal structural members, resulting in poor user press experience
Solution Approach 1:
A support structure is introduced as an intermediary element between the accommodation space and the middle portion of the flexible screen. This support structure extends into the accommodation space to provide upward support to the middle portion of the flexible screen when the terminal is in the unfolded state, preventing it from hanging in the air while maintaining the accommodation space functionality for folding.
2Adaptability or versatility
If the flexible screen is arranged at the folding inner side of the terminal product to enable folding, then the terminal product can be folded once for convenience, but the middle portion of the flexible screen lacks connection to internal structural members when unfolded, causing poor press experience
Solution Approach 1:
The support structure serves multiple functions: it provides structural support to the middle portion of the flexible screen when unfolded, maintains the accommodation space configuration for folding operations, and connects the flexible screen to the internal structure of the terminal. This multi-functional design avoids the need for separate dedicated support 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
Enhances the user's press experience by ensuring the flexible screen is consistently supported and flat, preventing damage from compression and ensuring normal functionality.
Implementation Method 1
an elastic sheet disposed at an inner side of the housing and in the middle of the housing. When the foldable terminal is in a folded state, a middle portion of the elastic sheet protrudes towards the housing. When the foldable terminal is in an unfolded state, the middle portion of the elastic sheet deforms and protrudes in a direction opposite to the direction in which the middle portion of the elastic sheet protrudes when the foldable terminal is in the folded state

AI summary
The present disclosure provides a foldable terminal, including an elastic sheet. The elastic sheet provides an elastic force in a state, so as to keep the housing in a folded state, and the elastic sheet provides another elastic force in another state, so as to keep the housing in an unfolded state. When the foldable terminal is in the unfolded state, the elastic sheet supports an inner side of the flexible screen.
