Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible display panels face issues such as positional shifting, disconnection of wiring, and slipping off due to applied force, especially when the display area is increased.
Innovation Solution
An electronic device structure incorporating a flexible display panel with a movable module and housing components that allow for controlled curvature and stable positioning, including movable portions and spaces to manage the display panel's angles and sliding movements, preventing disconnection and slipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a flexible display panel is used to achieve foldability and larger display area, then the display area and flexibility are improved, but the display panel shifts in position when folded and wiring may disconnect when great force is applied
Solution Approach 1:
The patent applies the dynamics principle by implementing a movable component that can slide within a housing space. This movable component dynamically adjusts its position based on the degree of folding, allowing the display panel to maintain proper positioning during both folded and unfolded states. The movable component's ability to move and the housing space accommodate the display panel's curvature changes, preventing position shifts and wiring disconnections while maintaining reliability.
2Area of moving object
If the display area is increased using a flexible display panel, then the screen size is improved, but the display panel slips off from the electronic device when force is applied externally
Solution Approach 1:
The movable component is designed to slide within the housing space in response to external forces and folding states. This dynamic adjustment mechanism allows the display panel to be retained securely during both folded and unfolded configurations, preventing slippage while accommodating the larger display area and flexibility requirements.
3Volume of moving object
If a flexible display panel is folded, then the device achieves compact form factor, but the display panel forms unwanted curvature and shifts position
Solution Approach 1:
The movable component dynamically responds to the folding state by sliding to appropriate positions within the housing space. This dynamic positioning controls the curvature of the flexible display panel during folding, ensuring the panel forms the desired shape while achieving compact device form factor, and prevents unwanted position shifts.
