Bendable Display Hinge with Buffering Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting devices cause damage to soft displays when inwardly bent due to compression from the hinge module, as the bending radius of the plate is smaller than that of the hinge module, leading to deformation and breakage.
Innovation Solution
A bendable display apparatus with a hinge module featuring a row of parallel pivots, torsion units, and buffering modules with internal and external linking members and gears, allowing the hinge module to bend between unfolded and inwardly folded positions without compressing the mounted object, with the internal linking members moving away from the pivots to accommodate curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the hinge module is bent inwardly, then the supporting device achieves a curved construction, but the hinge module compresses the soft display causing damage
Solution Approach 1:
The patent makes the supporting device dynamically adjustable by introducing a hinge module that can switch between unfolded and folded states. The hinge module includes pivots and torsion units that allow dynamic bending while the buffering module dynamically adjusts the distance between the hinge module and carrying plate to prevent compression damage during bending operations.
Solution Approach 2:
The patent introduces a buffering module as an intermediary component between the hinge module and the carrying plate. This buffering module includes a buffering member with a buffering end that contacts the carrying plate, acting as a mediator to prevent direct compression of the soft display by the hinge module during bending, thus resolving the contradiction between achieving curved shape and preventing compression damage.
2Shape
If the bending radius of the plate is smaller than that of the hinge module, then the plate can be bent, but the hinge module compresses the plate causing deformation
Solution Approach 1:
The patent changes the geometric parameters of the supporting device during bending operations. The hinge module allows the supporting device to achieve different bending radii by rotating between unfolded and folded states. The buffering module adjusts the distance parameter between the hinge module and carrying plate, ensuring the carrying plate maintains an appropriate bending radius that prevents deformation while achieving the desired curved shape.
3Adaptability or versatility
If the hinge module is made more flexible to enable bending, then the supporting device can be folded, but the soft display is easily broken due to compression
Solution Approach 1:
The patent segments the supporting device into distinct functional modules: the hinge module for bending capability, the buffering module for protection, and the carrying plate for display support. This segmentation allows each module to perform its specific function independently - the hinge module provides folding capability while the buffering module protects the soft display from compression damage, thus maintaining both adaptability and reliability.
Solution Approach 2:
The patent implements beforehand cushioning by pre-configuring the buffering module with a buffering member positioned between the hinge module and the carrying plate. This buffering member is designed to contact the carrying plate and absorb compression forces before they can reach the soft display, providing prior protection against potential damage during bending operations and maintaining display integrity while enabling folding capability.

AI summary
A bendable display apparatus includes two supporting devices, a carrying plate, and a soft display mounted on the carrying plate. Each supporting device includes a hinge module and two buffering modules respectively installed on two opposite sides of the hinge module. Each buffering module includes an external linking member fixed on the hinge module, an internal linking member fixed on the carrying plate and being movable with respect to the external linking member, and a gear driven by the hinge module to move the internal linking member. Each hinge module is bendable between an unfolded position and an inwardly folded position. When the hinge module is bent from the unfolded position toward the inwardly folded position, the gear is driven by the hinge module to move the corresponding internal linking member away from the pivots.
