Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals with flexible displays face challenges in stably adjusting the size of the display, non-limiting the deformed portion to a specific position, supporting the extended display stably, and preventing breakage from external shocks.
Innovation Solution
A mobile terminal design featuring multiple frames that move relative to each other, coupled with a driver system to extend or contract the flexible display, including actuators, dampers, and lockers to manage the movement and support the display, ensuring stable and reliable adjustment of the display size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a flexible display is used to extend the display size, then the display can be extended in a desired size, but the deformed portion may be broken by external shocks
Solution Approach 1:
The flexible display is divided into multiple segments: a first region on the front side, a second region on the back side, and a third region that can be selectively positioned. This segmentation allows the display to be extended while protecting the deformed portion through strategic positioning of regions on different sides of the terminal body.
Solution Approach 2:
A buffer structure is provided to protect the flexible display from external shocks before damage can occur. The buffer absorbs impact forces and prevents direct transmission to the deformed portion of the display, thereby preventing breakage while maintaining extension capability.
2Area of moving object
If the flexible display is extended, then the available display size increases, but it becomes difficult to stably support the extended display
Solution Approach 1:
Different regions of the flexible display are assigned different functions and positions. The first region is disposed on the front side for primary display, the second region on the back side for additional display area, and the third region is selectively positioned to optimize both stability and available display size based on extension state.
Solution Approach 2:
The display structure transitions from a static configuration to a dynamic one where the third region can be selectively positioned on different sides of the terminal body. This dynamic reconfiguration allows the system to adapt to different extension states while maintaining stability through controlled region placement.
3Volume of moving object
If the flexible display is rolled up into the terminal body, then the terminal structure becomes more compact, but the display cannot be projected in a desired size
Solution Approach 1:
The flexible display transitions between a compact rolled-up state within the terminal body and an extended projection state. The driver enables controlled movement of display regions between these states, allowing the terminal to switch between compact storage and large display projection as needed.
Solution Approach 2:
The flexible display is nested within the terminal body when not in use, with regions rolled up into the compact structure. When extension is required, the display can be unrolled and projected outward, effectively using the nested configuration to achieve both compact storage and large display capability.
4Adaptability or versatility
If a driver system is added to move the frames and display regions, then the display size can be adjusted, but the device complexity increases
Solution Approach 1:
The driver system performs multiple functions: it moves the second frame relative to the first frame, moves the third frame relative to the second frame, and controls the selective positioning of the third region. This multi-functionality reduces the need for separate mechanisms and manages complexity through a unified control system.
