Dual Screen Folding Hinge for Continuous Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with multiple screens suffer from protruding hinges that create viewing gaps and discontinuities, preventing a continuous viewing experience when expanded.
Innovation Solution
A dual screen folding display hinge system that joins multiple screens to form a single, continuous display with a hidden hinge, utilizing a core member, rotatable brackets, and a detaining mechanism to stabilize at pre-defined angles, allowing for seamless rotation and interchange between display modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a protruding hinge is used to connect multiple screens, then the device structure is simple and easy to manufacture, but viewing gaps and discontinuities are created between screens
Solution Approach 1:
The hinge mechanism is nested within the device body, with the core member housed inside the housing and rotatable members positioned within the display assembly. This nesting allows the hinge to remain functional while being concealed, eliminating the protruding appearance that causes viewing gaps and maintaining display continuity.
Solution Approach 2:
A core member acts as an intermediary element between the housing and the rotatable members, providing a hidden pivot point that enables screen rotation without requiring external hinges. This intermediary mechanism allows the screens to be connected smoothly without visible gaps.
2Volume of moving object
If screens are folded inward in standby mode, then the device is compact and portable, but the screens cannot be viewed when the device is set to those modes
Solution Approach 1:
The display system is designed with dynamic rotatable members that can rotate between different positions (folded inward for portability, extended outward for viewing). This dynamic capability allows the same structure to serve multiple functions: maintaining compactness during transport while enabling full display visibility during use.
Solution Approach 2:
The hinge mechanism is pre-configured with detaining mechanisms that automatically position the rotatable members at optimal viewing angles when extended. This preliminary positioning ensures that when the device is opened for viewing, the screens are automatically oriented correctly without requiring manual adjustment.
3Shape
If a hidden hinge mechanism is implemented, then viewing continuity is improved, but the device complexity increases
Solution Approach 1:
The core member serves multiple functions: it acts as the pivot point for rotation, provides structural support for the hinge mechanism, houses the detaining mechanisms, and enables both folded and extended display configurations. This multi-functionality reduces the need for separate components, thereby managing complexity while achieving hidden hinge functionality.
Solution Approach 2:
The detaining mechanisms are merged with the core member and rotatable members, with detent features integrated directly into these components rather than being separate elements. This merging consolidates the number of parts and simplifies the overall assembly process, reducing device complexity while maintaining the hidden hinge design.
