Wide Display Mobile Terminal via Sliding Folder Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical mobile terminals have limited display areas, restricting their functionality, such as Internet web browsing, while increasing display size compromises mobility.
Innovation Solution
A mobile terminal design featuring a main body with a first display unit and a folder unit with a second display unit, connected by a sliding unit and hinge coupler, allowing the second display unit to slide and rotate adjacent to the first, forming a wide display area without increasing the terminal's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display unit size is increased to provide a wider display area for functions like Internet web browsing, then the display area is improved, but the mobility of the mobile terminal deteriorates
Solution Approach 1:
The display system is divided into two separate display units: a first display unit integrated into the main body and a second display unit integrated into the folder unit. This segmentation allows the display area to be expanded without increasing the size of the main terminal body, as the second display unit is housed in the detachable folder unit that can be opened and positioned adjacent to the first display unit.
Solution Approach 2:
The folder unit is designed to rotate open from a closed position to an open position, transitioning the second display unit from a compact stored state to an extended display state. This dimensional transformation allows the display area to be expanded in the third dimension (rotation angle) rather than increasing the footprint of the terminal in the plane dimensions.
2Area of stationary object
If the display unit size is increased to provide a wider display area, then the visual capability is improved, but the portability of the mobile terminal deteriorates
Solution Approach 1:
The display system is divided into two separate display units: a first display unit integrated into the main body and a second display unit integrated into the folder unit. This segmentation allows the display area to be expanded without increasing the size of the main terminal body, as the second display unit is housed in the detachable folder unit that can be opened and positioned adjacent to the first display unit.
3Area of stationary object
If a larger display area is provided to enhance functionality, then the service capability is improved, but the compactness of the mobile terminal deteriorates
Solution Approach 1:
The folder unit is designed to rotate open from a closed position to an open position, transitioning the second display unit from a compact stored state to an extended display state. This dimensional transformation allows the display area to be expanded in the third dimension (rotation angle) rather than increasing the footprint of the terminal in the plane dimensions.
Solution Approach 2:
The second display unit is nested within the folder unit, which itself is attached to the main body. When the folder unit is closed, the second display unit is concealed within the folder unit's volume. When opened, it extends outward to form the wide display area, effectively nesting the display capability within the terminal's compact form factor.

AI summary
A mobile terminal having a wide display unit is provided. The mobile terminal includes a main body having a first display unit therein. The mobile terminal includes a folder unit having a second display unit at an inner surface opposite to the first display unit. The terminal also includes a sliding unit connected to one end of the folder unit to guide the folder unit capable of performing a slide movement. The terminal includes a hinge coupler to connect the sliding unit and the main body such that the sliding unit rotates based on the main body. The folder unit positions the second display unit to be adjacent to the first display unit by performing a slide movement toward the main body when the folder unit is opened as the sliding unit rotates based on the hinge coupler, and a wide display unit is formed when a surface of the first display unit and a surface of the second display unit become in a single plane. Thereby, mobility of a mobile terminal while providing a wide display unit can be provided.
