Foldable Mobile Terminal Hinge Mechanism for Length Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with flexible displays face challenges in adapting to changes in side lengths between folded and unfolded states due to the thickness of the device.
Innovation Solution
A foldable mechanism is introduced, comprising first and second rotation assemblies with sliding plates, rotation shafts, and connection rods, allowing the shells to adapt to length differences during folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile terminal uses a flexible display screen that is foldable, then the mobile terminal can be switched between folded and unfolded states, but the two sides of the mobile terminal have different lengths in the folded state due to the thickness of the device
Solution Approach 1:
The hinge assembly is designed with dynamic adjustment capabilities, allowing the connection between first and second shells to adapt to length changes during folding and unfolding. The hinge includes rotatable and slidable components that enable the structure to dynamically compensate for the length difference caused by device thickness, maintaining side length equality in both folded and unfolded states.
Solution Approach 2:
The mobile terminal is divided into separate first and second shells connected by a hinge assembly. This segmentation allows independent movement and adjustment of each shell relative to the other, enabling the hinge to compensate for length differences caused by device thickness while maintaining overall structural integrity and side length equality.
2Adaptability or versatility
If the hinge structure is designed to accommodate length changes during folding, then the mobile terminal can adapt to different states, but the device complexity increases
Solution Approach 1:
The hinge assembly merges multiple functions into a single integrated structure that connects the first and second shells. It combines rotational and sliding mechanisms within one unified assembly, allowing the structure to accommodate length changes during folding while avoiding the need for separate adjustment mechanisms, thus reducing overall device complexity.
Solution Approach 2:
The hinge assembly serves multiple functions simultaneously: it connects the first and second shells, enables folding and unfolding movements, compensates for length differences caused by device thickness, and maintains side length equality. This multi-functionality reduces the need for additional specialized components, thereby controlling device complexity.

AI summary
A foldable mobile terminal, comprising: a flexible display screen (10); a first housing (31) and a second housing (32), the flexible display screen being provided on the first housing and the second housing; and a foldable mechanism (20) comprising a first rotating assembly (50) connected to the first housing and a second rotating assembly (60) connected to the second housing. The first and second rotating assemblies both comprise sliding plates (51, 61), rotating shafts (53, 63), and connecting rods (54, 64). The sliding plates are at least partially received in the housings, and can extend or retract with respect to the housings in a sliding manner. First ends of the connecting rods are slidably and hingedly connected to the rotating shafts, and second ends are rotatably connected to the housings.
