Protective Film With Movable Camera Shielding Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective solutions for electronic terminals with cameras do not adequately address the privacy concerns of users, as they either fail to shield the camera effectively or complicate its use.
Innovation Solution
A protective film for electronic terminals featuring a transparent protective film body with an avoidance hole and an accommodating cavity, along with a movably arranged shielding member. The film includes a first and second bonding layer, with the shielding member being configured to shield or unshield the camera, and a warning part to alert users when the camera is not shielded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a protective film is applied to protect the screen, then the screen protection is improved, but the camera functionality is blocked
Solution Approach 1:
The protective film is segmented into multiple layers: a transparent protective layer that covers the screen while allowing camera light passage through the avoidance hole, and a separate movable shielding member that can be positioned to block or expose the camera as needed. This segmentation allows the film to provide continuous screen protection while enabling camera functionality through the avoidance hole, and privacy protection when the shielding member blocks the camera.
Solution Approach 2:
The shielding member is designed to be movable between different positions - it can slide or rotate to either block the camera (privacy mode) or expose the camera (usage mode). This dynamic element allows the protective film to adapt its function based on user needs, transitioning between screen protection-only mode and screen-plus-camera-protection mode without compromising the protective function.
2Object-affected harmful factors
If a shielding member is added to block the camera, then privacy protection is improved, but the device structure becomes more complex
Solution Approach 1:
The shielding member is merged with the protective film structure itself rather than being a separate component. It is integrated into the film layers, with the avoidance hole formed in the protective layer and the shielding member positioned within the film assembly. This merging approach provides camera blocking functionality while maintaining a relatively simple, integrated structure that does not require additional separate mechanisms.
Solution Approach 2:
The shielding member is implemented as a thin, flexible element within the protective film assembly, allowing it to move smoothly between blocking and non-blocking positions. The thin-film construction enables the shielding function to be added without significantly increasing overall device complexity or thickness, as the entire assembly remains a flexible protective film that can be applied to the screen surface.
3Object-affected harmful factors
If an opaque shielding member is used to block the camera, then privacy protection is improved, but the warning visibility to users is reduced
Solution Approach 1:
The protective film employs different optical properties in different regions: the shielding member is opaque to block camera light and provide privacy protection, while the warning part is made transparent or translucent to allow visibility of underlying indicators or text. This local differentiation of optical quality enables the film to simultaneously achieve camera blocking and user warning visibility without compromise.

AI summary
The present application discloses a protective film of electronic terminal configured to be attached to an electronic terminal mounted with a camera and protect a screen of the electronic terminal. The protective film of electronic terminal includes a protective film body and a shielding member. The protective film body is defined with an avoidance hole and an accommodating cavity. The avoidance hole is for avoiding the camera when the protective film body is attached to the electronic terminal and in communication with the accommodating cavity. The shielding member is movably arranged in the accommodating cavity for shielding or not shielding the camera.
