Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with flexible screens face challenges in accommodating length changes during hinge closure and opening, requiring a hinge mechanism that supports the flexible screen effectively without causing damage.
Innovation Solution
A hinge mechanism comprising a middle support, left, and right side structures with rotating and lifting flexible screen support members, which adjust to parallel rotating shafts, allowing the flexible screen to be supported and maintained smooth transitions during folding and unfolding, preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional rigid hinge structure is used, then the hinge provides stable support, but it cannot accommodate the length changes caused by flexible screen folding and unfolding
Solution Approach 1:
The hinge incorporates a movement mechanism with rotatable and slidable components that dynamically adjust the position and orientation of the flexible screen support during folding and unfolding operations. This allows the hinge to adapt to length changes while maintaining screen support stability through controlled mechanical motion.
Solution Approach 2:
The hinge changes geometric parameters such as the angle between support members and the position of the flexible screen support during operation. By varying these parameters in response to folding states, the hinge accommodates length changes while preserving structural reliability.
2Volume of moving object
If the flexible screen is disposed inside the mobile terminal, then the terminal structure is compact, but the hinge must handle complex length and orientation changes during folding
Solution Approach 1:
The hinge is divided into multiple functional components including a middle support, left and right support members, a movement mechanism, and a flexible screen support. This segmentation allows each component to perform a specific function, managing the overall complexity through modular design while achieving the required compactness.
Solution Approach 2:
The movement mechanism is positioned within the space between the support members, and the flexible screen support is integrated into this nested structure. This nesting arrangement maximizes space utilization, maintaining terminal compactness while accommodating the necessary mechanical components.
3Reliability
If the hinge is designed to fully support the flexible screen during folding, then screen integrity is protected, but the hinge structure becomes more complex
Solution Approach 1:
A dedicated flexible screen support acts as an intermediary component between the hinge mechanism and the flexible screen. This mediator provides specialized support for the screen during folding and unfolding, protecting screen integrity while isolating the complexity of the support function from the main hinge structure.
Solution Approach 2:
The movement mechanism serves multiple functions: it supports the flexible screen, accommodates length changes, and enables folding motion. By combining these functions in a single mechanism, the design protects screen integrity without proportionally increasing overall structural complexity.
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 hinge mechanism ensures the flexible screen is fully supported and protected, enabling smooth folding and unfolding, thus extending the mobile terminal's service life by maintaining the screen's integrity and functionality.
Implementation Method 1
the left support member and the right support member are respectively rotatably connected to a left side and a right side of the middle support, and the rotating shafts thereof are parallel
Implementation Method 2
the lifting direction of the lifting flexible screen support member is relative to the thickness direction of the mobile terminal, when the hinge is folded to be closed, the lifting flexible screen support member descends to a low position, when the hinge is unfolded, the lifting flexible screen support member is raised to a high position
Implementation Method 3
The rotating shaft of the rotating flexible screen support member is parallel to the rotating shaft of the left support member and the right support member, and the movement mechanism is provided with the rotating flexible screen support member at the end away from the middle support, when the lifting flexible screen support member descends, the rotating flexible screen support member rotates downwards, when the lifting flexible screen support member rises, the rotating flexible screen support member rotates upwards

AI summary
A hinge for a mobile terminal with a flexible screen, the hinge includes a middle support and left and right side structures which respectively include a left support member and right support member, respectively rotatably connected to a left and right side of the middle support. The hinge has, both in the left and right support members, a space opening towards the middle support and flexible screen. A movement mechanism within the space supports the flexible screen. A U-shaped configuration with an upper portion gradually inclining to be folded is formed in the vicinity of a bending position when the hinge is folded, adapting to the folding/unfolding of the mobile terminal with a flexible screen, enabling the screen to be completely supported when unfolded, creating a smooth transition at the bending position, avoiding damage, and enabling the mobile terminal to achieve a longer service life.
