Magnetic Bracket Screen Protector for Residue-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen protectors for electronic devices are difficult to apply and often result in air bubbles, lint, or residue, and are not easily interchangeable, especially for devices with full visual screens or varying sizes and shapes, and can obstruct the view or interfere with device features.
Innovation Solution
A device and method using magnetically attached base and screen foil brackets that allow for easy installation and removal of screen protectors, accommodating various sizes and shapes, and ensuring unobstructed viewing by using planar, curved, or angled configurations with embedded magnets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adhesive screen protectors are applied to electronic devices, then screen protection is achieved, but installation is difficult and results in air bubbles, lint, or residue
Solution Approach 1:
The patent replaces adhesive bonding (chemical/mechanical system) with magnetic attraction (electromagnetic field system). Magnets are embedded in the screen protector frame and corresponding magnets in the device frame create magnetic attraction that secures the screen protector without adhesives, eliminating residue and simplifying installation and removal.
Solution Approach 2:
The patent extracts the adhesive layer from the screen protector system, removing the source of residue, bubbles, and installation difficulties. The magnetic attachment system operates without any adhesive materials, allowing clean installation and removal without leaving behind any sticky substances or trapped contaminants.
2Reliability
If permanent adhesive screen protectors are installed, then screen protection is secured, but interchangeability is lost and multiple protectors must be applied repeatedly
Solution Approach 1:
The patent transforms the static, permanent adhesive bond into a dynamic, reversible magnetic connection. The magnetic force can be easily overcome by pulling the screen protector away from the device, enabling quick interchangeability while maintaining secure attachment during normal use. Users can switch between different screen protectors (clear, privacy, anti-glare) without permanent commitment.
3Reliability
If conventional screen protectors are applied to full visual screens, then screen protection is achieved, but viewing may be obstructed or device features interfered with
Solution Approach 1:
The patent segments the screen protector into a frame structure with magnets positioned at corners or edges, rather than covering the entire screen surface with adhesive. This segmented approach allows the protective frame to secure the screen protector while leaving the visual display area completely clear and unobstructed, maintaining full viewing quality and device feature accessibility.
4Reliability
If multiple screen protectors are tried to achieve satisfactory installation, then better protection may be achieved, but time and materials are wasted
Solution Approach 1:
The screen protector frame is pre-equipped with magnets during manufacturing, and the device frame has corresponding magnetic elements pre-positioned. This preliminary configuration eliminates the need for users to perform complex alignment and bonding procedures during installation. The magnetic attraction automatically guides and secures the screen protector in the correct position, ensuring satisfactory installation on the first attempt and eliminating time waste from repeated failures.
