Decorative Magnetic Cover for Non-Metallic Screen Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional decorative magnetic coverings are unsuitable for non-metallic surfaces like screens as they require a metallic substrate and can damage the screen when removed, and existing attachment methods are not removable or safe for screens.
Innovation Solution
A decorative magnetic cover comprising two magnetized halves with opposite polarities, allowing them to be securely attached and removed from non-metallic surfaces without causing damage, featuring decorative or informational imprints on their outer surfaces, and a method for manufacturing these covers using polarized magnetic material and various printing techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional magnetic decorations are used, then they can adhere to metallic surfaces, but they are unsuitable for non-metallic surfaces like screens
Solution Approach 1:
The patent introduces a non-magnetic substrate as an intermediary layer between the magnetic elements and the non-metallic surface. This substrate allows the magnetic cover to be attached to screens and other non-metallic surfaces by providing a mounting surface that doesn't require magnetic properties, thus resolving the incompatibility between conventional magnetic decorations and non-metallic surfaces
Solution Approach 2:
The patent employs a composite structure combining magnetic material, non-magnetic substrate, and adhesive layers. This composite material approach creates a hybrid attachment system that leverages the strengths of different materials: magnetic attraction for securement, non-magnetic substrate for surface compatibility, and adhesive for bonding to non-metallic surfaces
2Strength
If adhesives or mechanical fasteners are used to attach decorations, then they can secure the covering, but they will damage the screen when removed
Solution Approach 1:
The patent replaces mechanical fasteners (screws, clips, suction cups) with a magnetic field-based attachment system. The magnetic attraction provides securement strength without requiring mechanical penetration or strong adhesive bonding that would damage the screen upon removal
Solution Approach 2:
The non-magnetic substrate acts as a mediator that distributes magnetic forces evenly across the attachment area, preventing localized stress concentrations that could damage the screen while still providing sufficient attachment strength
3Ease of operation
If a single-sided magnetic cover is used, then it can be attached to one surface, but it cannot provide secure attachment about both sides of a non-metallic surface
Solution Approach 1:
The patent divides the magnetic cover into two separate halves, each with its own magnetic elements and non-magnetic substrates. These halves are positioned on opposite sides of the non-metallic surface and attract each other through the surface, creating a secure sandwich-style attachment that distributes forces across both surfaces

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 removable and aesthetically pleasing or informative decoration on non-metallic surfaces like screens, providing safety and privacy without damaging the surface, with the magnetic strength to hold securely against various materials.
Implementation Method 1
a magnetized first half having a first inner surface and a first outer surface, said first half being formed from a sheet of magnetic material such that said first inner surface has a first polarity and said first outer surface has a second polarity opposite said first polarity; a magnetized second half having a second inner surface and a second outer surface, said second half being formed from a sheet of magnetic material such that said second inner surface of said second half has an opposite polarity from said first polarity of said first inner surface of said first half

AI summary
A decorative magnetic cover for use in attachment to a non-metallic surface such as window or screen is provided. The decorative magnetic cover includes a magnetized first half and a magnetized second half shaped substantially identical to the magnetized first half. Imprints are formed on outer surfaces of the first and second halves. There is also disclosed a method of forming a magnetic cover such that an inner surface of a first half of the magnetic cover has a first polarity and an inner surface of a second half of the magnetic cover has a second polarity opposite the first polarity to hold the magnetized first and second halve together about a surface.
