Solution Overview
Problem
Conventional curved-flexible display devices face challenges in increasing the interaction area, improving user experience, reducing production costs, and maintaining a sleek design while being easy to grip and store.
Innovation Solution
A curved-flexible display device featuring a flexible display screen with an arc bending area for interaction, a cylindrical storage housing with a rotation mechanism, and a limiting-fixing assembly that adheres the arc bending area to the storage housing using magnetic, Velcro, or mechanical means, allowing for efficient storage and expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a multi-screen design is used for curved display devices, then the interaction area is increased, but the process difficulty and production cost increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single flexible display screen to serve multiple purposes: it can be curved for compact storage and simultaneously provide a sufficient interaction area when expanded. The limiting-fixing assembly enables the same screen to function both as the primary display and as the interaction interface, eliminating the need for separate multi-screen designs while maintaining adequate interaction capabilities.
2Area of stationary object
If a multi-screen design is used for curved display devices, then the interaction area is increased, but the production cost increases
Solution Approach 1:
The patent reduces production cost by making the flexible display screen perform multiple functions simultaneously. Instead of requiring multiple separate screens for display and interaction, a single screen provides both functions when properly configured with the limiting-fixing assembly, thereby reducing material costs and simplifying the bill of materials.
3Adaptability or versatility
If the curved screen is clamped with a special structure at the end, then the screen can display partial function, but the appearance is affected and grip comfort is reduced
Solution Approach 1:
The patent applies segmentation by dividing the flexible display screen into two functional zones: a curved arc bending area that provides the interaction interface, and a flat area for primary display. The limiting-fixing assembly is positioned to engage only with the arc bending area, allowing the screen to maintain its curved configuration for storage while preserving the overall sleek appearance without protruding clamping structures.
Solution Approach 2:
The patent extracts the interaction function from the main display area and relocates it to the arc bending area. This allows the main display area to remain flat and visually appealing, while the extracted interaction capabilities reside in the curved portion that is neatly contained by the limiting-fixing assembly, preventing visual disruption to the overall device appearance.
4Adaptability or versatility
If the curved screen is clamped with a special structure at the end, then the screen can display partial function, but the grip comfort is reduced
Solution Approach 1:
The patent segments the screen into curved and flat areas, with the curved arc bending area serving as the interaction interface. The limiting-fixing assembly is designed to engage with this curved area in a manner that does not create protruding structures, thereby maintaining smooth contours that are comfortable for user gripping while still enabling the screen to display and interact.

AI summary
The present invention provides a curved-flexible display device, which comprises a flexible display screen (1), a storage housing (3), and a limiting-fixing assembly (5). The flexible display screen (1) comprises an arc bending area (11) at an end side of the flexible display screen (1). The arc bending area (11) has a display and touch function as a human-computer interaction interface. The limiting-fixing assembly (5) comprises a first member (51) disposed on an outer surface of the storage housing (3), and a second member (53) disposed at a back surface of the arc bending area (11) and cooperated with the first member (51). The second member (53) has an arc shape and a curvature of the second member (53) is the same as a curvature of the arc bending area (11). When the storage housing (3) is storing the curved flexible display screen (1), the limiting-fixing assembly (5) adheres and fixes the arc bending area (11) to the outer surface of the storage housing (3), the user interaction experience is improved, production cost is reduced, and the appearance is more beautiful.
