Multi-Screen Hinge Mechanism for Ergonomic Center Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen notebook computers either increase product thickness with built-in screens or cause center-of-gravity shift and ergonomic issues with add-on screens, failing to provide efficient and ergonomic dual-screen functionality.
Innovation Solution
An electronic device with pivotally connected screens that can align or separate, featuring a hinge module, connecting bases, and sliding screens to maintain ergonomic center alignment and allow for synchronized or individual display modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a built-in multi-screen design is used to expand display area, then the display range is improved, but the product thickness increases and screens cannot be used separately
Solution Approach 1:
The display system is divided into two independent screens (first screen and second screen) that can function separately or together. Each screen has its own connecting base and hinge module, allowing independent operation while maintaining the ability to combine for expanded display area without increasing overall device thickness when separated.
Solution Approach 2:
The connecting bases are designed with rotational capability around hinge modules, allowing the screens to dynamically adjust between aligned (combined display mode) and separated (individual display mode) positions. This dynamic reconfiguration enables the display area to be expanded only when needed without permanently increasing device thickness.
2Area of moving object
If an add-on screen is attached to one side edge to expand display, then the display area is improved, but the center-of-gravity shifts and visual angle deviates from center
Solution Approach 1:
The two connecting bases are positioned asymmetrically relative to the host - one on the front side and one on the rear side - creating a balanced distribution of display weight around the center point. This asymmetric placement prevents center-of-gravity shift while still providing expanded display area.
Solution Approach 2:
Instead of adding screens only to the side edges (one-dimensional expansion), the invention extends displays in multiple dimensions by placing connecting bases on both front and rear sides of the host, creating a three-dimensional balanced configuration that maintains ergonomic center alignment while expanding total display area.
3Quantity of substance
If multiple windows are zoomed out to display simultaneously on a single screen, then the display capacity is improved, but the display content becomes extremely small and not easy to see clearly
Solution Approach 1:
The display task is segmented across two independent screens, allowing each screen to display full-resolution content without being divided into multiple small windows. This provides clear, readable display quality while maintaining the ability to show multiple applications simultaneously across the combined display area.

AI summary
An electronic device with multi screens including a host, a hinge module, a first connecting base, a second connecting base, a first screen, and a second screen is provided. The hinge module is pivotally connected to the host and rotates along a first axial direction. The first connecting base is fixed on a first side of the hinge module. The second connecting base is pivotally connected to a second side of the hinge module and rotates along a second axial direction parallel to the first axial direction. The second connecting base is adjacent to the first connecting base. The first screen is slidably disposed in the first connecting base and the second connecting base. The second screen is detachably disposed in the second connecting base. The second connecting base is suitable for rotating relative to the hinge module to be aligned with or separated from the first connecting base.
