Screen Protector Grating Sheet Merging Magnetic Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen protectors for mobile devices lack a peep-prevention function, leading to privacy issues, and existing solutions with protruding structures hinder device closure and cause visibility problems due to viewing angle limitations.
Innovation Solution
A laminated screen protector with a grating sheet and attaching members integrated into the same layer, allowing for easy assembly and disassembly without external protrusions, ensuring smooth device closure and maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protruding functional component is added to the peep-protection sheet for magnetic attachment, then the attachment function is improved, but the device closure is hindered and the screen protector thickness increases
Solution Approach 1:
The patent merges the functional component (magnetic attachment element) and the decorative component into the same layer as the grating sheet, eliminating the need for separate protruding structures. This integration maintains the attachment function while reducing overall thickness and avoiding interference with device closure.
Solution Approach 2:
The functional component is nested within the same layer structure as the grating sheet, with both elements coated between outer cover films. This nesting approach allows the magnetic attachment function to be embedded without adding external protrusions that would prevent device closure.
2Ease of operation
If a protruding functional component is added to the peep-protection sheet, then the attachment function is improved, but the upper cover cannot close smoothly and sleep program execution is hindered
Solution Approach 1:
The functional component is merged into the same layer as the grating sheet, eliminating external protrusions that would physically block the upper cover from closing smoothly. This integration ensures that the attachment function is achieved without interfering with device closure and sleep program execution.
3Ease of operation
If the functional component protrudes from the protection sheet body, then the attachment function is improved, but the protection sheet body inclines and cannot be disposed in parallel to the screen surface
Solution Approach 1:
The functional component is merged into the same layer as the grating sheet, ensuring that both elements lie flat against the screen surface. This integration prevents the protection sheet body from inclining or bending, maintaining proper parallelism while still providing the attachment function through the magnetic element.
4Length of moving object
If the grating sheet and attaching member are integrated into the same layer, then the screen protector thickness is reduced and device closure is enabled, but the structural integrity may be compromised
Solution Approach 1:
The patent uses a composite structure where the grating sheet and attaching member are integrated into the same layer and coated between outer cover films. This composite construction distributes structural loads across multiple materials, maintaining structural integrity while keeping the overall thickness reduced for smooth device closure.
5Shape
If conventional peep-protection sheets are used without integrated functional components, then the screen surface remains flat, but the attachment and easy disassembly function is lost
Solution Approach 1:
The functional component is merged into the same layer as the grating sheet, maintaining the flatness of the screen surface while adding the magnetic attachment function. This integration allows the screen protector to be easily attached and disassembled without compromising the flat appearance or requiring external protrusions.

AI summary
A screen protector configured to be disposed on an attaching body on an electronic device in an attaching mode to correspondingly cover a display screen of the electronic device. The screen protector comprises a grating sheet and a first attaching member disposed vertically adjacent to each other side-by-side and coated between two outer cover films. The screen protector is disposed on the attaching body on the electronic device in an attaching mode through the attaching member, so that a viewing zone defined by the grating sheet correspondingly covers the display screen of the electronic device.
