Foldable Stylus Transmission Structure for Flexible Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in arranging and using a stylus with electronic devices that have flexible screens due to the challenges of accommodating the stylus when the screen is folded or unfolded.
Innovation Solution
A transmission structure is integrated into the electronic device, allowing the stylus to be accommodated in a gap when the screen is folded and positioned at a preset angle when unfolded, facilitated by a transmission gear assembly and hinge component that moves the stylus relative to the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible screen is folded to save space, then the device portability is improved, but the stylus cannot be properly arranged or accessed
Solution Approach 1:
The stylus is designed with dynamic movement capability through a transmission structure connected to the hinge component. As the flexible screen folds or unfolds, the hinge component drives the transmission structure (including transmission rod and gear assembly) to automatically move the stylus between a storage position within the housing and a usage position extending outward. This dynamic adaptation resolves the contradiction by making the stylus position change with the screen state, ensuring both portability when folded and accessibility when unfolded.
2Device complexity
If the stylus is fixed in position to simplify structure, then the device complexity is reduced, but the stylus cannot adapt to screen folding states
Solution Approach 1:
The stylus adjustment mechanism is merged with the existing hinge component that controls screen folding. The hinge component is not only responsible for screen movement but also integrated with the transmission structure that controls stylus position. This merging approach allows the stylus to adapt to screen folding states without adding completely separate adjustment mechanisms, thus reducing overall device complexity while maintaining adaptability.
Solution Approach 2:
The stylus positioning system is designed to be self-adjusting through the transmission structure connected to the hinge component. As the hinge component moves during screen folding, it automatically drives the transmission rod and gear assembly to reposition the stylus without requiring manual intervention or additional control systems. The system serves itself by utilizing the mechanical movement already present in the folding mechanism to achieve stylus position adaptation.

AI summary
An electronic device includes a flexible screen, a first housing, a second housing, a stylus, and a transmission structure. The flexible screen is connected to the first housing and the second housing, the transmission structure is arranged on the first housing, and the stylus is connected to the transmission structure; in a case that the flexible screen is driven to fold by the first housing and the second housing, the transmission structure drives the stylus to approach the flexible screen, to accommodate the stylus in a gap formed after the flexible screen is folded; and in a case that the flexible screen is driven to unfold by the first housing and the second housing, the transmission structure drives the stylus to move away from the flexible screen, to cause the stylus and the flexible screen to form a preset included angle.
