Dynamic Navigation Bar for Flexible Display Image Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with flexible displays face issues when the screen size changes, as the image size does not increase proportionally, leading to margin areas and inefficient use of the display space, especially when transitioning between closed and open states.
Innovation Solution
The electronic device includes a processor that manages the display screen size by terminating the output of a first navigation bar and initiating a second navigation bar, allowing the image to expand while maintaining its ratio, thus optimizing the use of the display area.

Engineering Contradiction Analysis
1Area of stationary object
If the display screen size is increased in a rollable electronic device, then the display area is expanded, but the image size does not increase proportionally causing margin areas and inefficient space utilization
Solution Approach 1:
The navigation bar is transformed from a static element to a dynamic one that automatically adjusts its size and position based on the display screen size. When the screen expands, the navigation bar expands proportionally, allowing the image to utilize the full display area without margin regions, thus resolving the contradiction between expanded display area and space utilization efficiency.
2Productivity
If the image size is increased to fill the expanded display area, then space utilization improves, but the image ratio may be distorted
Solution Approach 1:
The system dynamically changes the parameters of the navigation bar (size, position, and configuration) based on the display screen state. By adjusting the navigation bar's parameters rather than the image parameters, the image can expand to fill the display area while maintaining its original aspect ratio, thus resolving the contradiction between space utilization and image ratio preservation.
3Device complexity
If the navigation bar configuration remains fixed, then the interface is simple, but it cannot adapt to different screen sizes
Solution Approach 1:
The navigation bar is designed as a dynamic element that automatically adapts its configuration to different screen sizes. It includes multiple possible configurations (first navigation bar for normal size, second navigation bar for expanded size) that are selectively applied based on the display state, providing adaptability without requiring complex manual intervention.
Solution Approach 2:
The system changes the navigation bar's parameters (size, position, configuration type) based on the display screen size. This parameter-based adaptation allows the interface to remain simple in structure while achieving high adaptability to different screen states, resolving the contradiction between interface simplicity and screen size adaptability.

AI summary
An electronic device may include: a display module capable of changing the size of a display screen; a memory in which computer-executable instructions are stored; and a processor which accesses the memory and executes the instructions, wherein, when the size of the display screen is changed while displaying an image and a first navigation bar, the processor terminates output of the first navigation bar and initiates output of a second navigation bar; and changes the size of the image while maintaining an image ratio on the display screen.
