Expandable Mobile Terminal Body Frame with Dynamic Flexible Display Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals with flexible displays face challenges in maintaining durability, particularly when bent, and require a support structure that stably supports the display when extended, while also preventing damage from external impacts.
Innovation Solution
A mobile terminal design featuring a body frame that can expand and contract, a flexible display unit, a driving unit for size adjustment, and a sensing unit for user commands, allowing the display to be expanded or contracted based on user input without restricting the bending point to a specific position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flexible display unit is bent at a specific fixed position, then the structure is simple and easy to manufacture, but the durability is reduced due to repeated stress at the same bending point
Solution Approach 1:
The patent implements a dynamic bending mechanism where the flexible display unit can be bent at multiple positions along its length. The support structure includes multiple support points that can independently move to provide support at different locations, allowing the bending position to vary dynamically rather than being fixed. This distributes the mechanical stress across different regions of the display over time, preventing fatigue at any single point and thereby improving durability while maintaining manufacturing feasibility through modular support components.
2Area of moving object
If the flexible display unit is extended to increase screen area, then the display functionality is improved, but the stability of the display unit is reduced
Solution Approach 1:
The patent introduces a support structure as an intermediary element between the flexible display unit and the terminal housing. This support structure includes multiple support points that can independently adjust their positions along the display unit. When the display is extended, the support points provide distributed mechanical support to maintain stability. The support structure acts as a mediator that enables the display to achieve both large extended area and stable positioning by providing adjustable structural reinforcement without constraining the display's flexibility.
3Adaptability or versatility
If the flexible display unit is made more flexible to allow free bending, then the adaptability is improved, but the resistance to external impact is reduced
Solution Approach 1:
The patent implements a dynamic support system where support points can independently move and adjust their position along the flexible display unit. This dynamic configuration allows the support structure to adapt to different bending states while providing impact resistance. When the display is bent or subjected to external impact, the support points can reposition to provide optimal structural reinforcement at the required locations, thereby maintaining both high flexibility and impact resistance simultaneously.

AI summary
A mobile terminal comprises: a body frame that is expandable in a first direction and shrinkable in a second direction; a flexible display in which the area of a display unit positioned on the front surface of the body frame is expanded according to the expansion of the body frame; a driving unit that changes the size of the body; a sensing unit that senses a user command; and a control unit that controls the driving unit to expand or shrink the body frame on the basis of the user command sensed by the sensing unit. Thus, a screen of the display unit positioned on the front surface can be expanded through size adjustment. Because a part of the screen always faces the outside, a separate secondary display unit is not required, and the screen may be expanded step by step as needed.
