Flexible Display Lateral Expansion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable computers with rigid displays lack the flexibility to easily expand or collapse the display surface, limiting their portability and usability.
Innovation Solution
A portable computer design featuring a flexible display that can be horizontally expanded or collapsed using a housing with a motor, transmission gear set, linkage set, and a mechanism that allows the flexible display to be unfolded or folded, enabling lateral expansion of the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid display is used in a portable computer, then the display structure is simple and stable, but the display surface cannot be expanded or collapsed to improve portability
Solution Approach 1:
The display structure transitions from a static rigid configuration to a dynamic flexible configuration. The flexible display module can be unfolded to expand the display surface or folded to collapse it, allowing the display area to change dynamically based on user needs while maintaining structural stability through the housing and linkage mechanisms.
Solution Approach 2:
The display system is divided into a fixed portion and a moving portion that can independently move relative to each other. The flexible display is partially assembled to the fixing portion while the end portion passes through and is stored at the backside, enabling segmented movement and expansion without requiring the entire structure to move simultaneously.
2Adaptability or versatility
If a flexible display module is added to enable display expansion, then the adaptability and portability are improved, but the device complexity and structural requirements increase
Solution Approach 1:
The flexible display's end portion is nested within the housing structure by passing through the moving portion and being stored at the backside of the fixing portion. This nesting approach allows the display to be compact when folded while maintaining full expansion capability when unfolded, reducing the need for external storage space.
Solution Approach 2:
A linkage set acts as an intermediary mechanism between the motor and the flexible display assembly. The linkage set includes a linkage body connected to both the motor output and the flexible display, translating rotational motor motion into the linear expansion and contraction movements required by the display while simplifying the overall mechanical interface.

AI summary
A portable computer having flexible display including a housing, a motor, a transmission gear set, a linkage set, and a flexible display is provided. The housing includes a fixing portion and a moving portion movably connected to and partially overlapped on the fixing portion. The motor, the transmission gear set, and the linkage set are disposed in the housing respectively. The linkage set and the transmission gear set are coupled to each other to be a connection and drive mechanism of the fixing portion and the moving portion. A portion of the flexible display is assembled to the fixing portion, and an end portion of the flexible display passes by the moving portion and are wound and stored at a backside of the portion of the flexible display.
