Flexible Display Housing With Selective Roll-Out Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face mechanical vulnerability and inefficient power consumption when fully expanded, limiting user convenience and usability.
Innovation Solution
The device incorporates multiple independently operable displays that can be split and expanded as needed, with sliding housings and a flexible display that adjusts display area based on housing movements, allowing controlled expansion and reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the flexible display is fully expanded in existing electronic devices, then the display area is increased, but the mechanical vulnerability increases and user convenience deteriorates
Solution Approach 1:
The display system is divided into multiple independent displays (first display, second display, third display) that can be independently controlled and expanded. Each display can be selectively activated based on usage needs, allowing the user to expand only the necessary portion rather than the entire display area, thereby reducing mechanical vulnerability while maintaining usability.
Solution Approach 2:
The electronic device employs dynamic state transitions between different display configurations (first state with all displays retracted, second state with second display expanded, third state with third display expanded, fourth state with both expanded). The housing structures enable smooth transitions between these states, allowing the display area to adapt dynamically to user needs while minimizing mechanical stress on any single configuration.
2Area of stationary object
If the flexible display is fully expanded, then the display area is increased, but the power consumption increases
Solution Approach 1:
Instead of expanding the entire flexible display area, the system implements partial expansion where only the necessary display portions (second display or third display) are activated based on the specific usage scenario. This partial action approach reduces the active display area and corresponding power consumption while still providing adequate display space for the current task.
Solution Approach 2:
The system changes the operational parameters of the display system by selectively activating different display modules based on usage context. The processor controls which displays are powered and expanded, dynamically adjusting the active display configuration to match the current task requirements, thereby optimizing power consumption relative to the actual display area needed.
3Ease of operation
If multiple independently operable displays are implemented, then user convenience is improved, but the device complexity increases
Solution Approach 1:
The multiple displays share common structural support mechanisms and control systems. The first housing, second housing, and third housing form an integrated mechanical system that supports all display modules, allowing them to be controlled through a unified interface. This multi-functionality approach enables complex display configurations to be managed through standardized mechanisms, reducing the effective complexity despite having multiple independent displays.
