Pivoting Device Hinge Assembly for Flexible Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinges for flexible displays are complex, making it difficult to achieve a lighter and thinner design due to cumbersome components, which complicates assembly and hinders efficient folding mechanisms.
Innovation Solution
A pivoting device with a hinge assembly and support plates that include movable and fixed members, driven levers, and a torque-providing portion, allowing the support plates to tilt outward and accommodate the flexible display's length, featuring a simpler structure with sliding rails and oblique slots for efficient folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional hinge structure is used to satisfy the folded length of a flexible display, then the folding function is achieved, but the structure becomes complicated and cumbersome, making assembly difficult and preventing a lighter and thinner design
Solution Approach 1:
The patent merges multiple hinge components into an integrated hinge assembly that includes a base, movable members, fixed members, and driven levers working together as a unified structure. This consolidation reduces the number of separate parts and simplifies the overall hinge structure while maintaining the required folding functionality for flexible displays
Solution Approach 2:
The hinge assembly is segmented into functional modules: a base providing support, movable members that displace in arc-shaped paths, fixed members for mounting the flexible display, and driven levers with oblique slots. This modular segmentation allows each component to perform its specific function efficiently while reducing overall structural complexity
2Device complexity
If conventional hinge components are used, then the folding mechanism is achieved, but the device becomes heavier and thicker due to cumbersome components
Solution Approach 1:
By merging multiple hinge components into an integrated assembly, the patent eliminates redundant materials and reduces the total weight of the pivoting device while maintaining structural integrity and folding functionality
Solution Approach 2:
The hinge assembly is designed with thin-profile components including a base with rails and movable members that operate within a compact thickness, enabling a lighter and thinner pivoting device suitable for modern flexible display applications
3Device complexity
If conventional hinge components are used, then the folding mechanism is achieved, but the structure becomes cumbersome and assembly becomes difficult
Solution Approach 1:
The integrated hinge assembly combines multiple functions into a single manufacturable unit, reducing the number of assembly steps and making the manufacturing process more efficient while maintaining the complex folding mechanism required for flexible displays
4Adaptability or versatility
If the support plates are laid flat to provide support, then structural support is provided, but the folded length accommodation is limited; when the driven levers slide along the sliding rail portion and oblique slot, the support plates flip and tilt outwards to accommodate the display length
Solution Approach 1:
The support plates are designed to dynamically change their configuration from a flat stable state providing structural support to a tilted outward state that accommodates the folded flexible display. This dynamic adaptability is achieved through the interaction between driven levers, oblique slots, and sliding rail portions that enable controlled movement while maintaining stability in both positions

AI summary
A pivoting device, including a hinge assembly and at least two support plates. The hinge assembly includes a base, two movable members on the base, at least two fixed members connecting the movable members, and two driven levers on the base and driven by the fixed members; the base has at least two rails where the movable members are provided, the movable members enable a flexible display to be folded when moving in an arc-shaped path, and the fixed members each have an oblique slot allowing one driven lever to move therein. The support plates each have a sliding rail portion at an end thereof and allowing one driven lever to slide therein, and when the driven levers are slide along the sliding rail portion and the oblique slot simultaneously, the support plates are flipped up and tilt outwards.
