Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals with foldable display units require complex structures and increased thickness to accommodate dynamic power and external force transfer, leading to a cumbersome design.
Innovation Solution
A mobile terminal with a flexible display unit that includes a deformation area capable of being folded or unfolded using an external force, supported by a body portion and a deformation support unit featuring living hinges, elastic members, and magnet units to stabilize the display's curvature and facilitate easy switching between states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complicated structure is used to provide dynamic power or transfer external force for a bent or folded mobile terminal, then the foldable display functionality is achieved, but the appearance becomes complicated and the thickness increases
Solution Approach 1:
The mobile terminal body is divided into first and second bodies that can be detached from each other, with the folding unit formed between them. This segmentation allows the display to be folded while keeping each body portion simple and compact, resolving the contradiction between foldable functionality and structural complexity
Solution Approach 2:
The first display unit is nested between the first and second bodies, with the deformation support unit and folding unit integrated within the body structure. This nesting approach enables the foldable display to be accommodated without increasing overall device thickness or complicating the external appearance
2Adaptability or versatility
If a complicated structure is used to provide dynamic power or transfer external force for a bent or folded mobile terminal, then the foldable display functionality is achieved, but the thickness of the mobile terminal becomes thick
Solution Approach 1:
The deformation support unit with living hinge is localized at the folding area between the first and second bodies, rather than requiring a complex structure throughout the entire device. This localized approach enables folding functionality while maintaining thin profile elsewhere, resolving the thickness contradiction
Solution Approach 2:
The living hinge unit provides dynamic flexibility at the folding location, allowing the display to bend and fold as needed. This dynamic element is concentrated at the hinge area rather than requiring thick structural support throughout the device, maintaining thin overall dimensions
