Flexible Display Support Mechanism for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with flexible displays lack a supporting structure to maintain the display in an unfolded state, requiring users to continuously hold the display, which is inconvenient.
Innovation Solution
A portable electronic device design featuring a casing with a rotating shaft, driving assembly, and a supporting member that automatically moves to support the flexible display when it is unfolded, allowing the user to operate the device without holding it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display is wound and retracted in a cylindrical casing without supporting structures, then the device achieves portability and compactness, but the user must continuously hold one side of the flexible display to maintain the unfolded state, which reduces ease of operation
Solution Approach 1:
The supporting member is designed to automatically deploy and support the flexible display without requiring continuous user intervention. When the flexible display is pulled out, the supporting member rotates outward under the driving assembly's action, forming a stable support structure that maintains the display in the unfolded state autonomously
Solution Approach 2:
The supporting member transitions from a retracted state during winding to an extended support state during display usage. The rotating shaft and driving assembly enable the supporting member to dynamically adjust its position, rotating outward to form a predetermined angle (80-100 degrees) with the rotating shaft, providing adaptive support based on the display's operational state
2Ease of operation
If a supporting structure is added to maintain the flexible display in the unfolded state, then ease of operation is improved, but the device complexity increases due to additional components like the driving assembly and supporting member
Solution Approach 1:
The supporting member is integrated with the rotating shaft and driving assembly, sharing common structural elements and mounting points. The first end of the supporting member is fixed to the driving assembly, which is itself connected to the rotating shaft, creating a combined mechanism that reduces the number of separate components while maintaining the supporting function
Solution Approach 2:
The driving assembly serves dual functions: it drives the flexible display winding mechanism through the rotating shaft and simultaneously drives the supporting member to deploy and position itself. This multi-functionality reduces the need for separate driving mechanisms, thereby reducing overall device complexity while providing the necessary support structure

AI summary
The application discloses a portable electronic device comprising a casing, a rotating shaft, a driving assembly, a flexible display and a supporting member. The housing has a long axis opening. The rotating shaft and the driving assembly are disposed in the housing, and the driving assembly is connected to the rotating shaft. The flexible display is wound around the rotating shaft. A first side of the flexible display is connected to the rotating shaft and a second side is located in the long axis opening. A first end of the supporting member is fixed to the driving assembly. When the second side of the flexible display moves outward from the long axis opening, the rotating shaft rotates and drives the driving assembly to drive a second end of the supporting member to move from the long axis opening toward the second side of the flexible display.
