Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window coverings require permanent attachment devices like screws and hardware, which can damage surfaces and make it difficult to quickly change or replace them, especially for windows and doors with metal or non-metal frames.
Innovation Solution
A universal magnetic curtain window covering with magnets positioned along the upper and lower ends, allowing secure attachment to metal or non-metal surfaces without the need for hanging hardware, and featuring non-magnetic surface adapters for securement to non-metallic surfaces, enabling multiple configuration options and easy installation/removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent attachment devices like screws and mounting hardware are used to secure window coverings, then the window covering is securely attached, but the door or wall surface is permanently damaged and the covering cannot be quickly replaced
Solution Approach 1:
The patent replaces the mechanical screw-and-hole attachment system with a magnetic field-based attachment system. Magnets embedded in the window covering interact with ferromagnetic materials in the door frame to provide secure attachment without physical penetration or permanent damage to the surface.
Solution Approach 2:
The patent introduces ferromagnetic material layers or strips as intermediaries between the magnetic curtain and the door surface. These intermediaries enable magnetic attachment to non-ferromagnetic surfaces while maintaining attachment security without damaging the underlying surface.
2Reliability
If permanent mounting hardware and brackets are used to install window coverings, then the covering is stable and secure, but installation is time-consuming and replacement is difficult
Solution Approach 1:
The patent eliminates time-consuming mechanical installation processes involving brackets, screws, and drilling by using magnetic attraction for instant attachment. The magnetic curtain can be simply placed against the door surface and immediately secured through magnetic force, enabling quick installation and removal.
Solution Approach 2:
The patent extracts and eliminates the need for permanent mounting hardware, brackets, and fastening mechanisms from the installation process. By removing these complex mechanical components, the system achieves both stability through magnetic force and time efficiency through simplified attachment.
3Device complexity
If magnets are positioned only along the periphery of the magnetic curtain, then the structure is simple, but the attachment strength and stability are insufficient
Solution Approach 1:
The patent segments the magnetic attachment system into multiple independent magnet arrays distributed across the curtain surface. This segmentation allows each magnet array to contribute independently to the overall attachment strength, providing both structural simplicity and enhanced reliability through distributed magnetic forces.
Solution Approach 2:
The patent applies different magnet configurations to different regions of the curtain based on local requirements. Stronger magnetic arrays are positioned in areas requiring greater attachment force, while simpler configurations are used where less force is needed, optimizing both simplicity and attachment strength.
4Reliability
If the magnetic curtain is designed to attach only to metal surfaces, then the magnetic attachment is strong, but the curtain cannot be used on non-metallic door frames
Solution Approach 1:
The patent introduces ferromagnetic material layers or strips as intermediaries between the magnetic curtain and non-ferromagnetic door surfaces. These intermediary layers provide the necessary magnetic properties for strong attachment while being compatible with various door materials including wood, plastic, and glass, thereby maintaining attachment strength while expanding surface compatibility.
Solution Approach 2:
The patent designs the magnetic curtain system to function universally across different door materials by incorporating adaptable attachment mechanisms. The system can attach directly to ferromagnetic surfaces through magnetic force and indirectly to non-ferromagnetic surfaces through ferromagnetic intermediaries, achieving multi-surface compatibility while maintaining reliable attachment.

AI summary
The present invention describes a window covering which is useful for securing to objects having windows without using permanent attachment devices. The window covering preferably contains a plurality of magnets arranged along the upper end and along the lower end. The magnets are arranged so that they are coupleable or securable to a metal part of a window itself or a metal surface which houses the window as well as one or more additional magnets positioned within the window covering. The window covering further comprises one or more non-magnetic surface adapters constructed and arranged to secure to at least one magnet along a first surface and to a second, non-magnetic surface along a second surface. The window covering provides at least one contact point for securing to at least one non-magnetic surface.
