Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable terminal devices with flexible screens have limited user experience due to restricted functionality and inefficient folding mechanisms, often requiring users to compromise on viewing angles and power consumption.
Innovation Solution
A foldable terminal apparatus with a bendable touch screen that can switch between two states, utilizing a telescopic supporting frame and inductive electromagnets to expand and retract, allowing full or partial display on a flat plane, and a terminal control method to adapt content display based on the screen's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bendable touch screen is folded to about one-half of its original size by bending on both sides or once in the middle, then the terminal size is reduced, but the user experience is limited and the degree of performance development is low
Solution Approach 1:
The terminal body is divided into a front body and a rear body that can relatively move with respect to each other, while the bendable touch screen is segmented into multiple regions (first region, second region, third region, fourth region) that can be independently controlled. This segmentation allows the screen to display content in various configurations (fully expanded, partially expanded, wrapped around the terminal) rather than simply folding to half size, thereby improving user experience while maintaining compact form factor.
Solution Approach 2:
The patent implements dynamic control of the bendable touch screen by allowing it to switch between multiple states: fully expanded flat state, partially expanded state, and wrapped state around the terminal. The front and rear bodies can also dynamically adjust their relative positions. This dynamic adaptability enables the terminal to optimize between size reduction and display quality based on user needs, resolving the contradiction between compact size and user experience.
2Area of stationary object
If the bendable touch screen surrounds the terminal body in the first state, then the screen area is maximized, but the structural stability during folding is compromised
Solution Approach 1:
A supporting frame is introduced as an intermediary structure between the bendable touch screen and the terminal body. This supporting frame provides structural support during the folding and unfolding processes, ensuring stability while allowing the screen to maintain its large display area when expanded. The supporting frame acts as a mediator that enables the screen to wrap around the terminal body without compromising structural integrity.
Solution Approach 2:
The supporting frame is designed to be accommodated within the terminal structure in the folded state and expands to support the full display area in the unfolded state. This nesting approach allows the supporting structure to provide stability during folding while being invisible when not needed, maximizing the display area without compromising structural stability.
3Stability of the object's composition
If the telescopic supporting frame expands into a plane to support the bendable touch screen, then the screen stability is improved, but the device complexity increases
Solution Approach 1:
The supporting frame utilizes a telescopic structure with connecting sections that can expand and contract like an accordion. This flexible yet stable structure provides the necessary support for the bendable touch screen when expanded, while maintaining a compact form when retracted. The telescopic design offers a balance between providing structural stability and avoiding excessive complexity compared to rigid support mechanisms.
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
Enhances user experience by providing flexible display options, efficient power management, and improved structural stability during folding and unfolding, enabling full or partial screen expansion for optimal content viewing.
Implementation Method 1
the supporting frame is a telescopic supporting frame having one end fixedly connected to the terminal body; the telescopic supporting frame comprises at least two connecting sections having radial dimensions decreasing or increasing progressively in a direction away from the terminal body
Implementation Method 2
the foldable terminal apparatus further comprises an inner and outer sliding gear set arranged between every two adjacent connecting sections of the telescopic supporting frame
Implementation Method 3
The bendable touch screen is switched between a first state and a second state. In the first state, the bendable touch screen surrounds the terminal body on an outer side of the terminal body, and in the second state, the fixed end of the bendable touch screen is located on the terminal body and the free end is located outside the terminal body

AI summary
Embodiments of the present invention provide a foldable terminal, a terminal control method and device, a terminal, and a storage medium. The terminal comprises a terminal body and a bendable touch screen. The two ends of the bendable touch screen along a bending direction are respectively a fixed end and a free end, the fixed end being connected to the terminal body. In a first state, the bendable touch screen surrounds the outer side of the terminal body; and in a second state, the fixed end of the bendable touch screen is located on the terminal body, and the free end is located outside the terminal body and expands the bendable touch screen.
