Dynamic Keyboard Mechanism for Foldable Display Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible screens with foldable designs lack touch and press feedback, making typing input inefficient due to the absence of tactile feedback typically provided by physical keyboards.
Innovation Solution
A display device with a keyboard assembly between the housing and flexible display screen, featuring a driving component and keyboard component that can be raised or lowered along the light emitting direction, incorporating elastic keyboards and typing parts to simulate a physical keyboard experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual touch keyboard is used on a foldable flexible screen, then the device maintains flexibility and portability, but touch and press feedback are lost reducing typing efficiency
Solution Approach 1:
The patent implements a dynamic keyboard structure where the keyboard component can move between a raised state (providing tactile feedback for typing) and a flattened state (maintaining device flexibility). The driving component enables this dynamic transformation, allowing the keyboard to adapt its form based on operational needs, thus resolving the contradiction between typing efficiency and device flexibility
Solution Approach 2:
The keyboard component is nested within the device housing and can be repositioned between raised and flattened positions. When not in use for typing, the keyboard component can be flattened or retracted into the device body, maintaining the flexibility and portability of the foldable screen while providing tactile feedback when needed
2Productivity
If a physical keyboard component is added to provide tactile feedback, then typing efficiency improves, but the device structure becomes more complex
Solution Approach 1:
The patent merges the keyboard component with the flexible display screen assembly, where the keyboard component shares the same housing and structural framework as the display. This integration reduces overall device complexity compared to adding a separate physical keyboard system, while still providing tactile feedback through the elastic deformation of the keyboard component
Solution Approach 2:
The keyboard component utilizes elastic materials that change their physical parameters (deformation, stiffness) in response to pressing forces. This allows the keyboard to provide tactile feedback through material property changes rather than requiring complex mechanical switch structures, thereby improving typing speed while controlling device complexity
