Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with flexible display modules lack a configuration for processing touch inputs differently between folded and unfolded states, and there is no standardized interface for multiple folded states, affecting user efficiency and work environment adaptability.
Innovation Solution
An electronic device with a foldable housing and a flexible display module that includes multiple areas and foldable areas corresponding to hinge structures, allowing the processor to detect touch inputs and switch between different application screens based on the state of the hinges, enabling separate processing of touch inputs in folded and unfolded states and providing a differentiated interface for multiple exposed screen areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display module is used to enable folding states, then adaptability to different usage scenarios is improved, but the complexity of processing touch inputs and determining display areas worsens
Solution Approach 1:
The display area is segmented into multiple distinct areas (first display area, second display area, third display area) corresponding to different folding states. Each area is assigned specific applications and touch input processing rules, allowing the system to handle complexity through structured division rather than uniform processing
Solution Approach 2:
The system dynamically determines the active display area and associated applications based on the real-time folding state of the flexible display module. The processor automatically adjusts which area is active and which applications can receive touch inputs, enabling adaptability without requiring complex manual configuration
2Productivity
If multiple display areas are exposed in different folding states, then user efficiency is improved, but the difficulty of determining appropriate applications for each area worsens
Solution Approach 1:
Applications are pre-assigned to specific display areas based on their functional characteristics. The first application is assigned to the first display area, the second application to the second display area, and the third application to the third display area. This preliminary assignment eliminates the need for real-time analysis when determining appropriate applications
Solution Approach 2:
Each display area is given distinct functional characteristics and is associated with specific applications suited to its size and position. The first display area (larger area in folded state) is suited for the first application, while the second and third display areas (smaller exposed areas in unfolded states) are suited for the second and third applications respectively
3Ease of operation
If touch inputs are processed separately for folded and unfolded states, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
Touch input processing is segmented by display area. Each display area has its own touch input processing rules and associated applications. This segmentation allows simple, dedicated processing logic for each area rather than complex unified processing, achieving ease of operation through structured simplicity
