Dual Display Mobile Device Screen Switching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile terminal devices with two display screens, users cannot easily access functions on the hidden screen while maintaining the first screen state, limiting usability.
Innovation Solution
A system and method that allows switching between two states: one where the first display module faces outside and the second is hidden, and another where both display modules face outside, enabling the user to detect a screen switching operation and display the hidden screen on the first display module when the operation is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the first cabinet is placed on top of the second display module with the first display module facing outside (first screen state), then the device maintains a compact form factor, but the user cannot access functions on the hidden second screen
Solution Approach 1:
The patent displays a copy of the second screen's content on the first display module when a screen switching operation is detected. This allows the user to access and interact with the second screen's functions through the first display module without changing the physical arrangement of the cabinets, thus maintaining the compact form factor while enabling full access to all screen functions.
2Ease of operation
If both display modules are arranged facing outside (second screen state), then the user can access both screens simultaneously, but the device occupies more space
Solution Approach 1:
The first display module serves multiple functions: it displays the first screen content normally, and upon detecting a screen switching operation, it displays the second screen's content. This multi-functionality allows the user to access both screens through a single display surface, eliminating the need to expand the device's physical configuration while maintaining full access to all screen functions.
3Adaptability or versatility
If the user switches between first and second screen states, then access to hidden screen functions is enabled, but the switching operation adds complexity to the device control
Solution Approach 1:
The system automatically detects the screen switching operation through the operation detector and autonomously switches the display content on the first display module. The user simply needs to perform a predefined gesture or operation, and the system handles the complexity of state management, content switching, and display control automatically, minimizing the perceived complexity for the user while maintaining high adaptability.

AI summary
A first cabinet comprising a first display module and a second cabinet comprising a second display module are provided. A switching is allowed between: a first state in which the first cabinet is placed on top of the second display module and the first display module faces outside, and a second state in which the first cabinet and the second cabinet are arranged next to each other and the first display module and the second display module face outside. A first screen to be displayed by the first display module and a second screen to be displayed by the second display module are stored and a screen switching operation is detected. Displaying of the first screen on the first display module is canceled and the second screen is displayed on the first display module, when the screen switching operation is detected in the first state.
