Solution Overview

Problem

Existing window coverings for metal-framed windows and doors require permanent attachment devices, which can damage the structure and make it difficult to easily replace or reconfigure the coverings.

Innovation Solution

A magnetic curtain window covering with magnets positioned along the upper and lower ends, allowing secure attachment to metal surfaces without the need for screws, hardware, or curtain rods, enabling multiple configuration options and easy installation/removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If permanent attachment devices (screws, hardware, curtain rods) are used to secure window coverings, then the window covering is securely attached, but the door or wall structure is damaged and replacement becomes difficult

Engineering Contradiction:

Improveattachment securityVSAvoidstructural damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical attachment system (screws, hardware, rods) 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 damage to the structure.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic field acts as an intermediary force between the window covering and the door frame. Instead of direct mechanical contact that causes damage, the magnetic field transmits the attachment force through space, allowing secure fastening without physical intrusion into the door or wall structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If permanent attachment devices are used, then the window covering is securely fixed, but easy replacement and reconfiguration is prevented

Engineering Contradiction:

Improveattachment securityVSAvoidreplacement ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The attachment system transitions from a static permanent fixation to a dynamic reversible connection. The magnetic attachment allows the window covering to be easily attached and detached by overcoming the magnetic force, enabling flexible reconfiguration and replacement without permanent installation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

By replacing mechanical fastening systems with magnetic attraction, the patent enables simple attachment and detachment operations. Users can easily install or remove the window covering by pulling it away from the magnetic field, providing operational flexibility while maintaining secure attachment during use.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If magnets are positioned only along the periphery, then the curtain can be attached, but multiple configuration options are limited

Engineering Contradiction:

Improveattachment simplicityVSAvoidconfiguration flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The magnetic attachment system is divided into multiple independent magnetic elements distributed across the window covering surface. This segmentation allows different portions of the covering to be attached or detached independently, enabling multiple configuration options such as partial coverage, different positioning heights, and flexible arrangement patterns.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The distributed magnetic elements provide universal attachment capability across the entire window covering. Each magnetic element can function independently or in combination with others, allowing the same window covering to be configured in multiple ways (full coverage, partial coverage, different positions) without requiring different attachment mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

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.
