Hinge Module Buffering Mechanism for Bendable Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting devices compress and damage soft displays when inwardly bent due to the hinge module's inability to distribute the bending stress effectively.
Innovation Solution
A bendable display apparatus with a hinge module featuring parallel pivots, torsion units, and buffering modules that allow the hinge module to bend between unfolded and inwardly folded positions without compressing objects, using internal and external linking members and a driving mechanism to maintain the hinge module's position and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hinge module is inwardly bent, then the supporting device achieves a curved construction for portability, but the hinge module compresses the soft display causing damage
Solution Approach 1:
The patent applies dynamics by making the total length of the hinge module changeable during bending. The buffer module enables the distance between the first end and second end of the hinge module to increase during inward bending, allowing the module to dynamically adapt its length to accommodate the curved construction without compressing the display.
Solution Approach 2:
The buffer module acts as an intermediary mechanism between the hinge module and the soft display. It absorbs and manages the dimensional changes during bending through the collaborative movement of the driving member, transmitting member, and linking members, preventing direct compression of the display while enabling portability.
2Device complexity
If the hinge module total length remains constant during bending, then the structure is simple, but the plate mounted on the inner surface is deformed
Solution Approach 1:
The patent transforms the static hinge structure into a dynamic one where the total length can change. The buffer module with its movable components (driving member, transmitting member, internal linking member) enables the hinge module to dynamically adjust its length during bending, preventing plate deformation while maintaining manageable structural complexity.
3Force
If the hinge module compresses the soft display during bending, then the bending force is transmitted effectively, but the soft display is easily broken
Solution Approach 1:
The buffer module serves as an intermediary that manages force transmission during bending. Through the coordinated movement of the driving member, transmitting member, and linking members, it allows controlled dimensional change that accommodates bending forces without transmitting compressive forces to the soft display, thereby protecting display strength.
Solution Approach 2:
The patent applies parameter changes by allowing the total length of the hinge module to change during bending. This dimensional parameter change is achieved through the buffer module's mechanism, which converts the bending action into a lengthening of the hinge module rather than compression, thereby protecting the display from damage.

AI summary
A 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 movably disposed on the external linking member, a driving member installed on the hinge module and movably disposed on the external linking member, and a transmitting member installed on the external linking member and driven by the driving member to move the internal linking member. The 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 driving member of each buffering module moves the corresponding internal linking member away from the pivots by using the transmitting member.
