Bendable Display Buffering Mechanism for Hinge Stress Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting devices cause damage to soft displays when bent outwardly due to stretching, as the hinge module deforms the display by extending it.
Innovation Solution
A bendable display apparatus with a hinge module and buffering modules that allow the display to bend without stretching, using pivots, torsion units, and buffering mechanisms to manage the bending motion and distribute stress, preventing deformation of the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hinge module is bent outwardly, then the supporting device can be folded to a curved structure, but the hinge module stretches the carrying plate and soft display causing damage
Solution Approach 1:
The buffering module acts as an intermediary between the hinge module and the carrying plate. It includes a transmitting shaft with a rack gear that engages with the spiral track on the pivot, converting the bending motion into controlled movement of the external connecting member along the internal connecting member. This intermediary mechanism prevents direct stretching of the carrying plate while enabling the hinge to fold outwardly.
Solution Approach 2:
The invention changes the parameter of connection rigidity by using a slidable external connecting member on the internal connecting member. During bending, the external connecting member moves along the internal connecting member, changing the effective length and rigidity of the connection. This allows the hinge module to fold while maintaining constant total length and preventing stretching of the carrying plate.
2Manufacturing precision
If the hinge module total length is kept constant during bending, then the carrying plate is not stretched, but the external connecting member must move relative to the internal connecting member requiring complex buffering mechanism
Solution Approach 1:
The buffering module is segmented into distinct functional components: the internal connecting member with positioning portion, the external connecting member that slides, the transmitting shaft with gearing portion and fixing portion, and the driving member with rack gear. This segmentation allows each component to perform its specific function while working together to maintain constant hinge module length during bending.
Solution Approach 2:
The invention replaces a simple rigid connection with a mechanical transmission system involving gears and rack. The rack gear on the driving member engages with the gearing portion on the transmitting shaft, converting rotational motion into linear motion of the external connecting member. This mechanical substitution enables precise control of the connecting members' relative movement to maintain constant overall length.

AI summary
A bendable display apparatus includes a carrying plate, two supporting devices disposed on an inner side of the carrying plate, and a bendable display mounted on an outer side of the carrying plate. Each supporting device includes a hinge module and two buffering modules respectively arranged on two opposite sides of the hinge module. Each buffering module includes an internal connecting member fixed on the hinge module, an external connecting member fixed on the carrying plate and slidably disposed on the internal connecting member, a driving member driven by a spiral track of the hinge module, and a transmitting member driven by the driving member for moving the external connecting member. When the hinge modules are bent, each supporting device is a curved structure and arranged inside of the bendable display, and each external connecting member slides relative to the corresponding internal connecting member toward the hinge module.
