Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face challenges in maintaining service continuity when transitioning between unfolded and folded states, particularly in ensuring seamless display content presentation and user experience without requiring additional user input.
Innovation Solution
The electronic device includes a first flexible display and a second display, with sensor circuitry to detect position transitions and control the displays accordingly, maintaining application execution by switching content presentation between displays based on detected directions and conditions.

Engineering Contradiction Analysis
1Volume of moving object
If the device transitions from unfolded to folded state, then the device becomes more compact and portable, but the display content may be interrupted or lost
Solution Approach 1:
The system performs preliminary detection of the folding transition using sensor circuitry before the display content is lost, and proactively switches between displays to maintain content presentation. The processor detects the transition state and pre-empts content interruption by activating the appropriate display in advance.
Solution Approach 2:
The system ensures continuous display of application content by switching between the first flexible display and second display during the folding transition. The application execution state is maintained, and the display content is seamlessly transferred from one display to another, ensuring uninterrupted visual feedback to the user throughout the transition process.
2Reliability
If the device switches displays during folding transition, then service continuity is maintained, but the system complexity increases
Solution Approach 1:
The second display, originally designed for rear viewing in folded state, is made multi-functional by enabling it to display application content when the device is folded during specific transitions. The display system universally handles both front and rear display functions through a single coordinated mechanism, reducing the need for separate specialized systems.
Solution Approach 2:
The system uses sensor circuitry integrated within the device to automatically detect folding transitions and trigger display switching without external input. The processor autonomously manages the display state transitions based on sensor feedback, enabling the system to self-regulate display management during folding operations.
3Ease of operation
If the device maintains application execution state during folding, then user experience is improved, but energy consumption increases
Solution Approach 1:
The system periodically monitors the device state through sensor circuitry to detect folding transitions, and only maintains full application execution state when necessary (during folding transitions). Between transitions, the system can enter lower power states, using periodic sensing rather than continuous monitoring to balance user experience with energy conservation.

AI summary
An electronic device is provided. The electronic device includes a foldable housing. This electronic device transitions from an unfolded position to a folded position while providing content through a front display in the unfolded position. The electronic device identifies a direction in which a display of the electronic device faces, on the basis of detecting the transition. The electronic device determines whether to provide the content, on the basis of whether the display direction before the transition corresponds to the display direction after the transition.
