Triple-Hinge Foldable Mobile Terminal Hiding Fold Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable mobile terminals with flexible screens can only be folded once and do not provide a visually integrated experience when folded, affecting user experience and aesthetics.
Innovation Solution
A foldable mobile terminal design featuring three main bodies with pivotable connections, allowing for multiple folds while hiding the folded lines from view, using a 'U'-shaped frame to accommodate the second and third main bodies within the first, and incorporating magnetic and fastening mechanisms for secure alignment and space optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a flexible screen is folded once to achieve a compact structure, then the mobile phone becomes more portable, but it cannot provide a large-sized display screen that needs to be folded multiple times
Solution Approach 1:
The mobile phone is divided into three independently pivotable main bodies (first, second, and third main bodies), each capable of relative movement. This segmentation allows the device to be folded multiple times while maintaining compactness, as each segment can be independently positioned to achieve various folded configurations.
Solution Approach 2:
The second and third main bodies are designed to be received within the accommodating chamber of the first main body when folded. This nesting arrangement allows multiple folded states while maintaining a compact overall structure, enabling the device to achieve both small volume and multiple folding capabilities.
2Ease of operation
If two parts are pivotably connected to achieve folding, then the mobile phone can be folded, but the folded lines are visible and the visual effect of integrality is lost
Solution Approach 1:
When the mobile phone is folded, the second and third main bodies are received within the accommodating chamber of the first main body, causing them to overlap with each other. This overlapping arrangement hides the folded lines from external view, maintaining the visual effect of integrality while preserving the folding capability for compact storage.
3Area of moving object
If multiple main bodies are used to enable multiple folds, then the display size can be increased, but the device complexity increases
Solution Approach 1:
Each main body is equipped with both a display screen and functional components (camera, flashlight, speaker, microphone), allowing any main body to function as the primary operational unit. This multi-functionality reduces the need for complex switching mechanisms between different folded states, thereby managing device complexity while enabling multiple folds and large display area.

AI summary
A foldable mobile terminal includes a first main body, a second main body and a third main body. The first main body includes a frame and a body portion. The frame has an accommodating chamber in which the body portion is securely received. The second main body rotatably connects with the frame. The second main body is rotated relative to the frame to be received in the accommodating chamber. The third main body rotatably connects with the third main body. The third main body rotates relative to the second main body to be received in the accommodating chamber. The present disclosure provides a foldable mobile terminal for which when the second main body is rotated to be received in the accommodating chamber and the third main body is rotated to be received in the accommodating chamber, due to the shielding effect of the frame of the first main body, the folded position cannot be viewed from an outer appearance of the mobile terminal. User's requirement of an integrity can be satisfied. In addition, since the foldable mobile terminal can achieve a twice folding and a twice unfolding, user's use requirements under different conditions can be satisfied thereby to promote user experience.
