Magnetic Screen Protector Mounting for Residue-Free Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen protectors are difficult to remove and replace without leaving adhesive residue or damaging the screen, and their stability is compromised by repeated installation and removal.
Innovation Solution
A magnetic fixing assembly comprising a fixing unit with a metal surface and adhesive, and a magnetic unit with magnets and adhesive, allowing detachable attachment to the screen protector, ensuring stability and ease of replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to install the screen protector, then the screen protector can be firmly fixed on the display screen, but the screen protector cannot be removed or replaced without leaving adhesive residue or damaging the screen
Solution Approach 1:
The patent replaces the adhesive bonding mechanism with a magnetic attraction mechanism. The magnetic unit containing magnets is used instead of adhesive to create a reversible, residue-free attachment system that allows easy removal and replacement while maintaining fixing stability through magnetic force.
2Reliability
If a frame is used to install the screen protector, then the screen protector can be securely mounted, but the frame wears out during repeated installation and removal, affecting stability and longevity
Solution Approach 1:
The patent replaces the mechanical frame structure with a magnetic attachment system. The magnetic unit with magnets provides a wear-resistant alternative to physical frames, eliminating the wear and tear issue while maintaining mounting stability and extending service life through non-contact magnetic force transmission.
3Reliability
If adhesive is used to attach the screen protector, then the screen protector remains firmly fixed, but the structure of the screen protector is damaged during removal
Solution Approach 1:
The patent substitutes adhesive bonding with magnetic attraction to achieve firm attachment without compromising structural integrity. The magnetic force provides sufficient attachment strength while allowing clean removal without damaging the screen protector structure, as there is no adhesive to peel or damage.
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
Enables easy removal and replacement of screen protectors without adhesive residue and wear, maintaining stability and extending the life of the assembly.
Implementation Method 1
The at least one magnet is mounted on the connecting part and faces the top surface of the fixing unit... the magnetic unit and the fixing unit are magnetically attracted to each other

AI summary
A magnetic fixing assembly for a screen protector is configured to detachably install a screen protector on a surface of a display screen and has a fixing unit and a magnetic unit. The fixing unit has a first adhesive sheet, such that the fixing unit can be attached to a border of the display screen. The magnetic unit has a connecting part, an extending part, and at least one magnet. The connecting part is detachably mounted on the fixing unit, and the at least one magnet is mounted on the connecting part, such that the magnetic unit and the fixing unit are magnetically attracted to each other. The extending part extends from a side of the connecting part, and the screen protector can be attached to the extending part. Therefore, the screen protector can be detached from the display screen.
