Flexible Display Translation Mechanism for Compact Form Factor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with sliding mechanisms, such as clamshell and slider designs, face challenges in achieving a compact form factor while maintaining a large display surface area, often resulting in bulkiness due to the need for two device housings and issues with crumpling or pillowing of flexible displays.
Innovation Solution
An electronic device with a single device housing featuring a flexible display integrated into a blade assembly that translates between extended, retracted, and peek positions, utilizing a tensioner mechanism and actuator to maintain a flat display shape and automatically adjust based on sensor inputs for optimal usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a sliding mechanism with two device housings is used (clamshell or slider design), then the device can be smaller in closed position, but the device becomes bulky when closed due to requiring two housings
Solution Approach 1:
The display is segmented into multiple sections that can be independently positioned. The flexible display is divided into a first section and a second section that can be arranged in different configurations (side-by-side, stacked, or overlapping), allowing the device to maintain a compact form factor while providing large display area through spatial segmentation rather than requiring multiple housings.
Solution Approach 2:
The patent transitions from a two-dimensional planar display arrangement to a three-dimensional spatial configuration. The flexible display sections can be folded, stacked, or positioned at different depths within a single housing, utilizing the Z-dimension to create multiple display areas without increasing the device's footprint, thereby resolving the contradiction between compact size and large display area.
2Area of stationary object
If a flexible display is used in a sliding mechanism, then the display can provide large surface area, but the flexible display crumples or pillows during translation
Solution Approach 1:
The patent employs a flexible display constructed with thin-film technology that can bend and deform without crumpling. The flexible display includes a substrate and functional layers that maintain structural integrity during translation, allowing the display to be positioned in various configurations (extended, retracted, or partially extended) while maintaining a smooth, pillow-free surface through the inherent flexibility and tensile strength of the thin-film construction.
Solution Approach 2:
The display system is designed to be dynamic rather than static, with the flexible display capable of smooth translation between extended and retracted positions. The mechanical guidance system ensures the flexible display moves along a controlled path that prevents buckling or crumpling, maintaining optimal shape throughout the motion range while preserving large display area.
3Adaptability or versatility
If the flexible display is made more flexible to enable translation, then the display can move between positions, but the display becomes more susceptible to crumpling and pillowing
Solution Approach 1:
The flexible display is constructed using composite materials that combine flexibility with structural reinforcement. The multi-layer construction includes flexible substrates paired with support layers that prevent crumpling, allowing the display to be highly adaptable in position while maintaining reliable structural integrity during translation and in various deployed states.
