Screen Protector with Magnetic Shielding Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen protectors face issues with attachment stability, reusability, and the inability to effectively attenuate electromagnetic radiation, particularly due to poor adhesion methods and material limitations in existing electrostatic and magnetic attachments, as well as the lack of radiation shielding.
Innovation Solution
A screen protector design featuring a magnetically absorbed piece with a shielding layer made of Fe-containing polymer, combined with an anti-glare sheet and functional film, uses a self-restoring adhesive and decorative elements for improved attachment stability and electromagnetic wave attenuation, allowing for easy assembly and disassembly and daily cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrostatic attachment method is used, then attachment process is simple, but attachment stability is poor and protector detaches when laptop is opened
Solution Approach 1:
The patent combines electrostatic attachment layers with magnetic attachment pieces in a single protector structure. The electrostatic layer provides initial attachment and ease of application, while the magnetic pieces embedded in the protector body provide enhanced attachment stability through magnetic attraction to the laptop screen, preventing detachment when the laptop is opened or moved.
2Reliability
If magnetic attachment with manganese steel sheets is used, then attachment effect is improved, but overall thickness is high and gap between screen and keyboard is large
Solution Approach 1:
The patent uses thin magnetic attachment pieces (thin films) instead of thick manganese steel sheets. These thin magnetic elements are embedded within the protector body, providing strong magnetic attachment effect while maintaining a thin overall structure that allows the laptop screen to close properly without creating a large gap between the screen and keyboard.
3Reliability
If magnetic attachment with manganese steel sheets is used, then attachment effect is improved, but manganese steel sheets may pierce ornaments when user accidentally bends the protector
Solution Approach 1:
The patent employs thin magnetic attachment pieces that are flexible and embedded within the protector body rather than using hard manganese steel sheets. This flexible thin-film approach allows the magnetic elements to bend with the protector without piercing through decorative ornaments or causing damage when the user accidentally bends the protector.
4Ease of manufacture
If 304 stainless steel sheets are used for magnetic attachment, then cutting process is simplified, but cutting dies wear significantly and processing accuracy is low
Solution Approach 1:
The patent changes the material parameter from 304 stainless steel sheets to thin magnetic attachment pieces made of softer magnetic materials. This material parameter change allows the use of laser cutting instead of mechanical cutting dies, eliminating the wear and accuracy problems associated with cutting dies while maintaining ease of manufacture through simplified laser cutting processes.
5Reliability
If traditional adhesive or electrostatic or magnetic screen protectors are used, then attachment is achieved, but electromagnetic radiation shielding is not provided
Solution Approach 1:
The patent creates a composite structure that combines traditional attachment materials (adhesive layers, electrostatic layers, magnetic pieces) with electromagnetic radiation shielding materials. This composite material approach allows the protector to simultaneously provide reliable attachment capability and shield against electromagnetic radiation from electronic devices, addressing both attachment and radiation protection requirements.
