Foldable Mobile Hinge Structure for Gap-Covering Side Decoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable mobile terminals face challenges in assembling side decorations without damaging the display, particularly when transitioning between unfolded and folded states, due to gaps and rigidity issues.
Innovation Solution
A mobile terminal design featuring a rotatable first and second body with a flexible display and a side decoration that overlaps the display, providing a seamless outer surface and coupling mechanisms to enhance rigidity and reduce bezel size, while absorbing external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a side decoration is assembled to cover a gap between display and bodies in an unfolded state, then the appearance is improved and gap is covered, but the display may be damaged during assembly
Solution Approach 1:
The side decoration is designed with a flexible portion that can dynamically change its position and shape. In the unfolded state, the flexible portion bends to cover the gap between display and bodies, improving appearance. During assembly in the folded state, the flexible portion can deform to avoid the display, preventing damage while maintaining the ability to cover gaps when needed.
Solution Approach 2:
The side decoration is divided into a rigid portion and a flexible portion. The rigid portion provides structural support and defines the overall shape, while the flexible portion can independently deform to either cover gaps or avoid the display during assembly, resolving the contradiction between appearance improvement and display protection.
2Shape
If the side decoration is rigid to define appearance, then the appearance is improved, but the assembly process may damage the display
Solution Approach 1:
The side decoration is segmented into rigid and flexible portions. The rigid portion maintains the desired appearance and structural definition, while the flexible portion is designed to be deformable during assembly, making the manufacturing process easier and safer by allowing the flexible portion to be positioned without damaging the display.
3Shape
If the side decoration covers the gap in unfolded state, then the appearance is improved, but the structure becomes more complex
Solution Approach 1:
The side decoration is divided into rigid and flexible portions, where each segment serves a specific function. The rigid portion provides structural support while the flexible portion handles the gap-covering function through deformation, achieving gap coverage without requiring complex mechanical structures or additional components.

AI summary
A mobile terminal is disclosed. The mobile terminal according to an embodiment of the present invention comprises a hinge assembly. The hinge assembly comprises: a pair of body rotation bodies which are arranged to be spaced apart from each other in the widthwise direction of a first body and a second body; a support bridge which is arranged between the pair of body rotation bodies and connects the body rotation bodies to each other; and a display support which is arranged to overlap with the support bridge in the widthwise direction of the first body and the second body and is formed to be movable by being linked to the movement of the support bridge, wherein the display support is, in a first state, arranged to support a flexible display and, in a second state, moves to be spaced apart from the flexible display.
