Rollable Display Audio Layout for Display State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rollable characteristic of flexible displays in electronic devices is not fully utilized in the arrangement of sound receivers, leading to low structural utilization and limited functionality, particularly in devices with full-screen designs.
Innovation Solution
An electronic device design that includes a first and second housing connected by a flexible display, with sound emitters and receivers positioned to ensure communication through specific holes, allowing the flexible display to switch states while maintaining sound reception functionality, and using sound reception signals to determine the display's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound receivers are arranged in a fixed position in the housing, then the structure is simple and easy to manufacture, but the structural utilization of the flexible display is not fully used and functionality is limited
Solution Approach 1:
The patent applies the dynamics principle by making the arrangement of sound receivers changeable rather than fixed. The first sound receiver is disposed in the second housing and can move with the flexible display as it rolls or unrolls, while the second and third sound receivers remain fixed in the first housing. This dynamic arrangement allows the sound receivers to adapt to different display states (rolled/unrolled), fully utilizing the flexible display's movement capability to enable diverse listening modes without requiring a completely reconfigurable structure.
2Adaptability or versatility
If the flexible display is made fully rollable to increase screen-to-body ratio, then portability is improved, but the arrangement of sound receivers cannot utilize the rolling characteristic
Solution Approach 1:
The patent applies segmentation by dividing the sound receiver arrangement into different groups with different mobility characteristics. The first sound receiver is segmented from the other sound receivers and placed in the second housing, allowing it to move with the flexible display. The second and third sound receivers remain in the first housing as fixed references. This segmentation enables the system to utilize the rolling characteristic of the flexible display for the first sound receiver while maintaining simple fixed positions for the others, achieving both adaptability and ease of manufacture.
3Reliability
If sound receivers are positioned to maintain communication through holes during display state switching, then sound reception functionality is preserved, but the structure becomes more complex
Solution Approach 1:
The patent applies self-service by utilizing the natural movement of the flexible display and housing to maintain sound reception functionality without requiring additional active control mechanisms. As the flexible display rolls or unrolls, the first housing and second housing move relative to each other, and the sound receivers automatically maintain their communication paths through the respective holes. The system leverages the inherent mechanical coupling between the display and housing, allowing the structure to serve itself in maintaining functionality during state transitions without complex control systems.
