Hinge Device Uniform Motion Distribution for Soft Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pivot pin devices are ineffective for flexible soft display screens as they cause the screen to be squeezed and crimped when flexed, fail to accurately locate the screen after flexing, and risk damage from large flexion angles or improper operation.
Innovation Solution
A hinge device with multiple joint units and motional shafts, featuring rotary shafts and sockets, and a frictional torque system that distributes motion uniformly across the display screen, ensuring even force distribution and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional rotary shaft is applied to a flexible soft display screen, then the display screen can be rotated and opened/closed, but the display screen will be squeezed and crimped due to the distance between the screen and the axis of the rotary shaft
Solution Approach 1:
The hinge device is divided into multiple joint units, each with its own rotary shaft and motional shaft. This segmentation allows the motion to be distributed across multiple points along the display screen, preventing concentration of force at a single location and thereby eliminating squeezing and crimping effects.
Solution Approach 2:
Motional shafts are introduced as intermediary elements between the rotary shafts and the display screen. These motional shafts transmit and distribute the rotational motion uniformly across multiple joints, ensuring that the display screen experiences even force distribution rather than localized squeezing.
2Ease of operation
If a conventional pivot pin device is applied to a flexible soft display screen, then the display screen can be flexed, but the soft display screen cannot be truly located after flexed or opened/closed
Solution Approach 1:
The frictional torque system provides continuous feedback resistance during the flexion and positioning of the display screen. This frictional torque helps the system to settle at stable positions and maintain accurate locating after flexion, preventing drift and ensuring precise positioning.
3Adaptability or versatility
If a hinge device is applied to connected with the soft display screen, then the display screen can be operated in different modes, but the soft display screen may be pressed and folded or damaged due to too large flexion angle or improper operation
Solution Approach 1:
The hinge device incorporates dynamic elements including motional shafts that can move relative to the joint units, and a frictional torque system that provides adaptive resistance. This dynamic design allows the hinge to accommodate various flexion angles and operating modes while automatically adjusting to prevent excessive force that could damage the display screen.
Solution Approach 2:
The frictional torque system allows for parameter adjustment in the torque characteristics of the hinge device. By adjusting the frictional torque, the device can be optimized for different operation modes while maintaining safety limits that prevent damage to the display screen under improper operation conditions.
4Ease of operation
If a conventional rotary shaft is applied to a flexible soft display screen, then the display screen can be rotated, but every part of the soft display screen is not uniformly forced
Solution Approach 1:
The hinge device is divided into multiple joint units distributed along the display screen, with each unit having its own rotary shaft and motional shaft. This segmentation ensures that the rotational force is distributed uniformly across multiple contact points, preventing concentration of force and achieving uniform forcing across the entire display screen.
Solution Approach 2:
Motional shafts serve as intermediary elements that transmit and distribute the rotational motion from the rotary shafts to the display screen in a uniform manner. This intermediary mechanism ensures even force distribution across all parts of the display screen during rotation operations.

AI summary
A hinge device applicable to soft display screen ensures that the total amount of motion is uniformly distributed to every motional shaft. The hinge device includes multiple joint units and motional shafts. Each joint unit has a shaft fixing section and a shaft guide section assembled with the motional shafts. Each joint unit has a top portion, a first side and a second side. A rotary shaft is formed on the first side along the top portion. A socket is formed on the second side along the top portion. A (soft) display screen is disposed on the top portions of the joint units. The shaft guide section is defined with a first position and a second position. When a user opens/closes the display screen, the rotary shafts serve as rotational fulcrums and the motional shafts are rotatably movable between the first and second positions of the shaft guide section.
