Rollable Display Screen Assembly for Mobile Terminal Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with large screens lack portability due to the inability to shrink the display screen, leading to increased overall size and reduced convenience for users.
Innovation Solution
A display screen assembly featuring a first rotating shaft and a flexible second display region that can be curled around the shaft, with a drawer mechanism allowing for extension or curling of the display region, enabling the display screen to be adjusted in size without increasing the terminal's overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display screen size is increased to provide a larger visual experience, then the display area is improved, but the overall size of the mobile terminal increases, reducing portability
Solution Approach 1:
The display screen is designed to be dynamically adjustable in size through a rolling mechanism. The flexible display screen can be rolled around a rotating shaft to extend the display area when needed, and rolled back to reduce the overall size for portability. This dynamic transformation allows the display to transition between different size states based on user requirements.
Solution Approach 2:
The flexible display screen is nested around a rotating shaft, with the display winding around the shaft when rolled. This nesting arrangement allows the display to be compactly stored within the terminal housing when not in use, while enabling full extension when the shaft rotates to unwind the display, effectively solving the contradiction between large display area and compact size.
2Length of moving object
If the display screen is made flexible and rollable to improve portability, then the overall size is reduced, but the structural complexity increases due to additional components
Solution Approach 1:
The rotating shaft serves multiple functions: it acts as the axis around which the flexible display rolls, provides a support structure for the display, and enables the mechanical transformation between extended and retracted states. This multi-functionality reduces the need for separate components, thereby managing structural complexity while achieving portability.
Solution Approach 2:
The flexible display screen is implemented as a thin, flexible film that can be rolled around the rotating shaft. This flexible membrane structure eliminates the need for rigid support frameworks, simplifying the overall structure while enabling the rollable functionality required for portability.
3Area of moving object
If the display screen is extended to provide a larger display area, then the visual experience is improved, but the portability is reduced due to increased size
Solution Approach 1:
The display system provides dynamic size adjustment capability, allowing users to extend the display area when needed for visual tasks and retract it when portability is prioritized. The rotating shaft mechanism enables smooth transition between extended and retracted states, giving users control over the balance between display area and portability based on immediate needs.
