Dual-Screen Foldable Structure With Sliding Hinge Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notebook computers with single screens are insufficient for modern user demands due to limited display space, and external screens are cumbersome to carry and prone to misalignment.
Innovation Solution
A foldable electronic device with a first and second screen, featuring a sliding structure and hinge mechanism that allows the screens to expand display range when unfolded and collapse for storage, eliminating the need for manual disassembly and reducing volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a single screen is used in notebook computers, then the device structure remains simple, but the display space becomes insufficient for modern user demands
Solution Approach 1:
The display system is segmented into a first screen and a second screen that can be independently positioned and controlled. The first screen is disposed at the first body while the second screen is disposed at the second body, allowing each screen to function independently or together, thereby expanding total display space without requiring a single overly complex display unit
Solution Approach 2:
The patent transitions from a single-plane display to a multi-dimensional display configuration by allowing the second screen to rotate relative to the first body and position itself at different angles and locations. This dimensional flexibility enables expanded display space while maintaining a relatively simple base structure that can adapt to various configurations
2Area of moving object
If an external screen is added to notebook computers, then the display space is expanded, but the device becomes cumbersome to carry and the external screen is prone to loosen or shift
Solution Approach 1:
The first screen and second screen are merged into a single integrated device where both screens are housed within the same first body structure. The second screen rotates relative to the first body but remains connected through the hinge structure, eliminating the need for separate external screens that need to be disconnected and stored. This integration ensures both screens remain stable and properly positioned during transport and use
Solution Approach 2:
The second screen is designed to be dynamically adjustable through rotation relative to the first body, allowing users to position it at different angles and locations based on their needs. This dynamic positioning capability, enabled by the hinge structure with sliding mechanisms, provides flexibility similar to external screens while maintaining permanent connection and stability, eliminating the loosen and shift problems associated with detachable external screens
3Ease of operation
If multiple screens are integrated into a foldable device, then manual disassembly is eliminated, but the mechanism complexity increases with sliding structures and hinge structures
Solution Approach 1:
The sliding structure and hinge structure are designed to enable automatic positioning and locking of the second screen relative to the first body. The sliding components guide the second screen into proper alignment, and the hinge mechanism naturally maintains stable positions through its mechanical design, reducing the need for complex manual adjustment mechanisms or electronic controls while still providing flexible screen configuration

AI summary
A foldable electronic device including a first body having a first side and a second side, a second body rotatably connected to the first side of the first body, at least one sliding structure disposed in the first body and adjacent to the second side, a first screen rotatably connected to the second body and movably disposed at the at least one sliding structure, at least one hinge structure disposed in the first body and connected to the at least one sliding structure, and a second screen disposed at the at least one hinge structure and located at the second side is provided. The second body is adapted to rotate relative to the first body and driving the first screen to move along the at least one sliding structure to switch to a closed state or an unfolding state.
