Sliding Keyboard Expands Display Area Without Bulk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers with external screens are bulky, unergonomic, and suffer from image segmentation issues due to the limited display area and awkward placement of external screens.
Innovation Solution
An electronic device with multiple screens that features a sliding rail assembly and a lifting base, allowing the keyboard to slide and lift expansion modules to extend the display area, eliminating segmentation and enhancing portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an external screen is connected to enlarge the display range, then the display area is increased, but the device becomes bulky and difficult to carry
Solution Approach 1:
The expansion module containing the secondary display is nested within the keyboard assembly, which itself is integrated into the notebook structure. The secondary display is positioned to be covered by the keyboard when closed, allowing the display area to be enlarged without increasing the overall device volume or portability characteristics.
Solution Approach 2:
The secondary display is arranged in a spatial relationship with the primary display such that it extends the display area in a different dimension. The expansion module can be positioned at the edge of the primary display, creating an extended display surface without increasing the footprint or bulk of the notebook device.
2Area of stationary object
If an external screen is disposed at the edges of the display body, then the display range is enlarged, but the center of gravity shifts and viewing angle changes making it unergonomic
Solution Approach 1:
The expansion module is designed with movable and adjustable characteristics, allowing it to be repositioned along the sliding rail assembly. This dynamic positioning capability enables the user to adjust the secondary display location to achieve an ergonomic configuration that balances the center of gravity and optimizes viewing angles for different usage scenarios.
Solution Approach 2:
The display system is segmented into a primary display integrated into the notebook and a separate expansion module containing the secondary display. This segmentation allows the secondary display to be independently positioned and adjusted, enabling ergonomic optimization without affecting the primary display or the overall notebook structure.
3Area of stationary object
If an external screen is connected to the display body, then the display area is enlarged, but an obvious segment appears between the external screen and display body affecting the picture display effect
Solution Approach 1:
The expansion module is designed to be visually integrated with the notebook device. The secondary display is positioned and configured to create a seamless visual transition with the primary display, minimizing or eliminating obvious segments. The keyboard covers the boundary area when closed, further hiding any segmentation between the two displays.
Solution Approach 2:
The keyboard serves as an intermediary element that covers the transition area between the primary display and the expansion module. When the notebook is closed, the keyboard obscures any visible segmentation, creating a seamless appearance. The sliding rail assembly also acts as an intermediary mechanism that allows smooth positioning of the expansion module to minimize visual discontinuities.

AI summary
An electronic device with multiple screens includes a first body, a second body, a keyboard, and at least one expansion module. The first body has a sliding rail assembly, a first end and a second end. The second body is rotatably connected to the first end of the first body. The sliding base is slidably connected to the sliding rail assembly of the first body. The lifting base is pivotally connected to one side of the keyboard facing the first end and is slidably connected to the sliding rail assembly. The at least one expansion module is detachably connected to the lifting base and is disposed between the second body and the keyboard. When the keyboard slides toward the second body, the sliding base is driven to move along the sliding rail assembly and away from the second end of the first body.
