Flexible Screen Unfolding via Fingerprint Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enhance the security of electronic devices with flexible screens, which are prone to being lost due to their small size, leading to potential leakage of user information.
Innovation Solution
A method and apparatus that utilize a fingerprint sensor to control the unfolding of a flexible screen, where fingerprint data is obtained and matched with preset data, and only upon successful matching, the screen is unfolded, thereby improving security by ensuring only authorized access can unfold the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the flexible screen is made small for portability, then the device becomes more portable and lightweight, but the device becomes easier to lose and harder to find
Solution Approach 1:
The patent implements fingerprint authentication before allowing the flexible screen to unfold. The fingerprint sensor captures and verifies user identity in advance, and only after successful verification does the control circuit enable the motor to unfold the screen. This preliminary security check ensures that even if the small device is lost, unauthorized persons cannot access the full screen and information.
2Reliability
If the flexible screen is kept folded for security, then unauthorized access is prevented, but the screen cannot be used when needed
Solution Approach 1:
The patent employs a feedback mechanism where the fingerprint sensor continuously monitors for authentication attempts. When the correct fingerprint is detected, the control circuit receives this feedback signal and automatically triggers the motor to unfold the flexible screen. This closed-loop control ensures that the screen transitions from a secured folded state to an accessible unfolded state based on real-time authentication feedback, balancing security with ease of operation.
