Retractable Flexible Display Mechanism for Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with large screens face challenges in portability due to their size, as the screen size is limited to accommodate convenience and portability requirements.
Innovation Solution
An electronic device featuring a rotatable mechanism and driving mechanism with a flexible display screen that can be retracted into a housing for compactness and extended for larger display, controlled by a controller to manage display areas based on the screen's length extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the screen size of the electronic device is increased to meet large-screen requirements, then the display area is improved, but the device size increases which deteriorates portability and convenience for holding
Solution Approach 1:
The display screen is designed to be dynamically extendable and retractable. The screen can be extended when large display area is needed and retracted when portability is prioritized, allowing the device to adapt between two states: compact mode for portability and extended mode for large-screen display.
Solution Approach 2:
The invention transitions from a static two-dimensional display plane to a three-dimensional extendable structure. The screen can protrude from the device body along the thickness dimension, effectively increasing display area without increasing the device's footprint area, thus resolving the contradiction between display size and portability.
2Adaptability or versatility
If a retractable flexible display screen is implemented to resolve the size contradiction, then both portability and large-screen display are achieved, but the device complexity increases due to additional mechanisms
Solution Approach 1:
The driving mechanism is integrated within the housing structure, and the rotatable mechanism is combined with the flexible display screen assembly. By merging these components into a compact integrated unit, the patent reduces overall structural complexity while maintaining the retractable functionality.
Solution Approach 2:
The flexible display screen is wound around and connected to the rotatable mechanism, forming a nested structure. The driving mechanism is received within the housing, and the rotatable mechanism is received within the housing as well. This nesting arrangement minimizes the space required for the mechanisms and simplifies the overall device structure.

AI summary
A method for controlling display and an electronic device are provided. The electronic device includes a housing, a rotatable mechanism, a driving mechanism, and a flexible display screen. The flexible display screen is wound on and connected to the rotatable mechanism. The housing has a light transmitting region, and part of the flexible display screen facing the light transmitting region forms a first display area of the electronic device. In response to different control signals, the controller controls the driving mechanism to rotate the rotatable mechanism in different directions to control retraction and stretching of the flexible display screen. According to a length of part of the flexible display screen extending out of the housing, the controller controls display of the first display area and a second display area of the flexible display screen extending out of the housing.
