Magnetic Screen Protection Filter for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices lack a practical solution for protecting screen privacy from nearby viewers, as existing privacy sheets are difficult to remove and can reduce screen brightness and sharpness, posing eye strain.
Innovation Solution
A screen protection filter with an attracting member that attaches to electronic devices' attraction components, allowing easy installation and removal, featuring a protection filter body with an attraction area and accommodation holes for the attracting member, which can be magnets or ferromagnetic components, ensuring rapid attachment and detachment while covering the display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a privacy sheet is adhered on the screen to prevent spying, then privacy protection is improved, but the screen brightness and sharpness deteriorate
Solution Approach 1:
The patent applies a magnetic attachment mechanism that allows the privacy protection film to be dynamically attached and detached. The film contains magnetic particles or a magnetic layer that interacts with a magnetic strip on the device frame, enabling easy installation and removal without permanent adhesion. This dynamic approach resolves the contradiction by allowing privacy protection only when needed, preserving screen brightness and sharpness when the film is removed.
Solution Approach 2:
The patent implements a removable privacy protection film that can be easily discarded (removed) from the screen. The magnetic attachment system allows users to detach the film without leaving residue or damaging the screen, enabling recovery of the original screen properties including brightness and sharpness when privacy protection is no longer required.
2Reliability
If a privacy sheet is adhered on the screen to prevent spying, then privacy protection is improved, but the ease of removal deteriorates
Solution Approach 1:
The magnetic attachment mechanism provides dynamic, reversible bonding that is easy to operate. Users can simply pull the film away from the magnetic field to remove it, or reposition it by moving it within the magnetic field. This eliminates the difficulty of removing permanently adhered privacy sheets while maintaining effective privacy protection when attached.
Solution Approach 2:
The patent replaces the traditional mechanical adhesion system (glue, tape) with a magnetic field-based attachment system. This substitution eliminates the need for chemical adhesives that are difficult to remove, allowing the privacy film to be easily detached by overcoming the magnetic force, thereby improving ease of operation.
3Reliability
If a privacy sheet is kept adhered on the screen, then privacy protection is improved, but eye strain increases due to reduced brightness and sharpness
Solution Approach 1:
The dynamic magnetic attachment system allows users to attach the privacy film only when privacy protection is needed (in public spaces) and remove it when using the device in private settings. This eliminates prolonged exposure to reduced screen quality, preventing eye strain while maintaining privacy protection when required.
Solution Approach 2:
The patent changes the state of privacy protection from permanent to temporary/conditional. By using magnetic attachment, the film can be easily installed and removed, allowing users to adjust the privacy protection parameter based on their environment. This prevents continuous degradation of screen brightness and sharpness that causes eye strain.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents nearby spying and maintains privacy by allowing easy attachment and removal of the screen protection filter, ensuring optimal screen brightness and sharpness without the drawbacks of traditional privacy sheets.
Implementation Method 1
The attracting member is disposed at the attraction area of the protection filter body. The protection filter body with the attracting member is attachable to the attraction component of the electronic device

AI summary
A screen protection filter includes a protection filter body and an attracting member. The protection filter body includes an attraction area and a protection area. The attracting member is disposed at the attraction area of the protection filter body. With the attracting member, the protection filter body is attachable to an attraction component of an electronic device, such that the protection area of the protection filter body correspondingly covers over a display screen of the electronic device to prevent nearby persons from spying display contents and keep privacy. By simply attaching the attracting member to the attraction component and removing therefrom, the screen protection filter can be easily attached to and removed from the display screen of the electronic device whenever needed.
