Magnetic Screen Protection Filter for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile device screen protection filters do not effectively prevent screen spying and are difficult to remove, often causing reduced screen brightness and sharpness, which can harm user vision.
Innovation Solution
A screen protection filter with an attracting member, such as magnets, that attaches to the device's attraction components, allowing easy installation and removal while reducing the viewing angle of light and protecting the screen from spying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a privacy sheet is adhered on the screen using conventional adhesive methods, then privacy protection is improved, but the difficulty of removal increases and residual glue remains
Solution Approach 1:
The patent replaces conventional adhesive bonding (chemical/mechanical adhesion) with magnetic attraction. The privacy filter includes magnetic elements that attract to corresponding magnetic elements in the display assembly, enabling secure attachment during use while allowing easy removal by overcoming the magnetic force, thus resolving the contradiction between reliable attachment and ease of removal.
2Reliability
If a privacy sheet is kept adhered on the screen continuously, then privacy protection is maintained, but screen brightness and sharpness deteriorate
Solution Approach 1:
The patent makes the privacy filter dynamic rather than static. The magnetic attachment allows the filter to be easily installed when privacy is needed and just as easily removed when privacy is not required, enabling users to adapt the privacy protection level to different usage scenarios, thus preventing continuous degradation of screen brightness and sharpness.
3Ease of manufacture
If conventional adhesive methods are used to attach the privacy sheet, then initial attachment is achieved, but the attachment mechanism becomes complex and difficult to control
Solution Approach 1:
The patent replaces complex adhesive systems (requiring surface preparation, controlled application, drying time, and cleanup) with a simple magnetic attachment system. Magnets can be directly integrated into the filter structure and will automatically attach to the display assembly without additional adhesive materials, simplifying both manufacturing and user operation.
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 persons from viewing the screen contents, maintains screen brightness and sharpness, and allows for easy attachment and detachment of the filter.
Implementation Method 1
The attracting member comprises a first attracting block... while the screen protection filter is attached to the display screen

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 and comprises at least one attracting block. 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.
