Flexible Display Shell Tilt Mechanism for One-Handed Unfolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Windable or foldable display apparatuses face challenges in user handling, as they become difficult to grasp with one hand when unfolded, and there is a risk of dropping during the unfolding process, especially for users with small hands.
Innovation Solution
A method and apparatus that includes a flexible display screen and a bottom shell with a first and second shell, where the first shell and flexible display screen are synchronously deployed or retracted, and the second shell moves away from or toward the first shell to form a preset angle, enhancing grasping and reducing the risk of dropping by creating a tilting mechanism that allows for easier one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display screen is unfolded to achieve a large display size, then the display area is improved, but the ease of one-handed operation deteriorates
Solution Approach 1:
The bottom shell is divided into a first shell and a second shell that can move relative to each other. The second shell can be tilted to form a support structure, segmenting the housing function into protective first shell and support second shell, enabling one-handed operation with large screens.
Solution Approach 2:
The second shell moves in a direction perpendicular to the plane of the flexible display screen, adding a dimensional element to the housing structure. This vertical movement creates a tilted support configuration that provides ergonomic handling for large unfolded displays.
2Area of stationary object
If the display screen is unfolded to achieve a large display size, then the display area is improved, but the stability during operation deteriorates
Solution Approach 1:
The second shell is designed to be movable relative to the first shell, transitioning between a closed state and a tilted support state. This dynamic adjustment allows the housing to adapt its configuration based on operational needs, providing stability when required and compact form when not in use.
Solution Approach 2:
The second shell automatically tilts to form a support structure when the flexible display screen is unfolded, providing self-stabilization for the device. The housing structure itself serves as a support mechanism, eliminating the need for external stands or supports.
3Ease of operation
If the display screen is kept small to maintain one-handed operation, then the ease of operation is improved, but the display area deteriorates
Solution Approach 1:
The bottom shell is divided into a first shell and a second shell that can move relative to each other. The second shell can be tilted to form a support structure, segmenting the housing function into protective first shell and support second shell, enabling one-handed operation with large screens.
Solution Approach 2:
The second shell moves in a direction perpendicular to the plane of the flexible display screen, adding a dimensional element to the housing structure. This vertical movement creates a tilted support configuration that provides ergonomic handling for large unfolded displays.
