Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible electronic devices face a design inconsistency and aesthetic appeal issue due to stepped portions when expanding or contracting display size, compromising portability and user experience.
Innovation Solution
A dual slidable electronic device design where the width of the flexible material on the back surface expands in accordance with the front surface display's width expansion, maintaining a consistent exterior design and enhancing aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased to improve user experience, then the display area is expanded, but the device dimensions increase making it less portable
Solution Approach 1:
The patent implements a flexible display that can dynamically change its effective size between expanded and contracted states. The display apparatus transitions between different display areas (e.g., 6.5 inches to 8 inches) allowing the device to provide large screen real estate when needed while maintaining a compact form factor for portability, thus resolving the contradiction between display area and device dimensions
Solution Approach 2:
The patent changes the physical state and configuration of the flexible display through controlled expansion and contraction. By altering the display's dimensional parameters (width, length, area) between different states, the device can optimize between large display area for user experience and compact dimensions for portability, effectively managing the trade-off between these two parameters
2Area of stationary object
If the flexible display width is expanded to increase display size, then the display area is improved, but stepped portions appear on the back surface degrading aesthetic appeal
Solution Approach 1:
The patent applies different properties to different parts of the device: the front surface features a flexible display that can expand and contract, while the back surface features a flexible material that mirrors these dimensional changes. This local differentiation ensures that when the display expands, the back surface material also expands proportionally, preventing stepped portions and maintaining aesthetic appeal, thus resolving the contradiction between display area and exterior design consistency
Solution Approach 2:
The patent creates visual homogeneity between the front and back surfaces by ensuring that both the flexible display and the flexible material on the back surface expand and contract together. This synchronized dimensional change maintains consistent exterior design across both surfaces, eliminating the aesthetic degradation caused by stepped portions while still allowing display area to be expanded

AI summary
According to certain embodiments, an electronic device comprises: a housing surrounding at least a side surface of the electronic device; a flexible display exposed through a first surface of the electronic device facing a first direction, the exposed area varying based on the movement of the housing; and a flexible material exposed through a second surface of the electronic device facing a second direction opposite to the first direction, the exposed area varying based on the movement of the housing, wherein the width of the flexible material that is exposed through the second surface, expands in a third direction in accordance with the expansion of the width of the flexible display in the third direction, the third direction being substantially perpendicular to the first direction and the second direction.
