Bendable Display Hinge With Buffering Modules for Outward Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting devices cause damage to bendable displays when outwardly bent due to the stretching of the hinge module, which leads to deformation and breakage of the display.
Innovation Solution
A dual-shaft hinge module with buffering modules is used, where the dual-shaft hinge module includes two shafts with spiral grooves, a transmitting member, and side wing members, and the buffering modules have internal and external connecting members that move in a predetermined distance to absorb the bending stress, preventing damage to the bendable display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hinge module is used in the supporting device, then the device can achieve rotation and bending movement, but the hinge module stretches the bendable display when outwardly bent, causing deformation and breakage
Solution Approach 1:
The patent introduces buffering modules with elastic elements (springs) that are pre-configured to absorb tensile stress before it can damage the bendable display. These buffering modules are positioned at strategic locations in the supporting device to cushion the impact of bending forces, preventing the hinge module from stretching the display during outward bending operations.
Solution Approach 2:
The patent introduces buffering modules as intermediary components between the hinge module and the bendable display. These buffering modules act as mediators that absorb and dissipate tensile stress, preventing direct transmission of stretching forces to the display. The buffering modules serve as a protective interface that allows bending movement while filtering out harmful stress.
2Stability of the object's composition
If the hinge module is made more rigid to maintain structural stability, then the supporting device can maintain its shape, but it increases the stretching force on the bendable display when bent
Solution Approach 1:
The patent divides the supporting device into multiple independent modules: hinge modules for rotation, buffering modules for stress absorption, and connecting members for structural linkage. This segmentation allows each module to perform its specific function - the hinge modules provide rigid structural support and stability, while the buffering modules independently absorb tensile stress, preventing the stretching force from reaching the bendable display.
Solution Approach 2:
The buffering modules are designed to temporarily absorb (discard) tensile stress during bending operations, then recover and release this energy when the bending force is removed. The elastic elements in the buffering modules store potential energy during outward bending and release it during return to the original position, preventing permanent deformation or damage to the display while maintaining structural stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dual-shaft hinge module and buffering modules effectively absorb the stress of bending, allowing the bendable display to be folded without deformation, thus preventing damage and maintaining the display's integrity.
Implementation Method 1
The two shafts are respectively arranged in the two rotation axes and each have a spiral groove recessed on an outer surface thereof. The transmitting member is clamped between the two shafts. The transmitting member has two driving portions respectively protruding from two opposite sides thereof and is respectively inserted into the two spiral grooves of the two shafts.
Implementation Method 2
Each of the two buffering modules includes an internal connecting member and an external connecting member. The external connecting member has a slanting hole non-parallel to each of the two rotation axes and sleeved on the limiting portion of the corresponding side wing member. When the carrying plate is bent along at least one of the two axes between an unfolded position and an outwardly folded position, the external connecting member of each of the buffering modules slides with respect to the corresponding internal connecting member, and each of the limiting portions moves in the corresponding slanting hole from the first end to the second end.
