Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional methods for hanging articles such as banners or posters often result in permanent damage to surfaces, are difficult to reposition, and provide insecure attachments, especially on non-walled structures.

Innovation Solution

A magnetic hanging system using ferromagnetic retainers and retaining plates that can be attached and detached, along with mounting discs for various surfaces, and reinforcing tabs for added security, allowing secure and temporary hanging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If nails or screws are used to hang articles, then the attachment is secure and permanent, but the surface is damaged and the mounting cannot be easily repositioned

Engineering Contradiction:

Improveattachment securityVSAvoidsurface damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical penetration system (nails and screws that physically pierce surfaces) with a magnetic field-based retention system. The magnetic retainers attract ferromagnetic retaining plates through magnetic force, eliminating the need for physical penetration and thus preventing surface damage while maintaining secure attachment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental attachment parameter from mechanical interlocking (physical penetration) to magnetic attraction (field-based force). This parameter change allows the retaining plates to be securely held without penetrating the surface, resolving the contradiction between secure attachment and surface protection.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If nails or screws are used to hang articles, then the attachment is secure, but the mounting points cannot be easily repositioned

Engineering Contradiction:

Improveattachment securityVSAvoidrepositionability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces dynamic repositionability to the attachment system. The retaining plates can be easily moved to different locations on ferromagnetic surfaces, and the magnetic retainers can be quickly detached and reattached at new positions. This dynamic capability allows flexible repositioning while maintaining secure attachment at each position.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If clips or hooks are used to hang articles on wires or ropes, then the mounting is temporary and repositionable, but the attachment is insecure and articles shift laterally

Engineering Contradiction:

Improvetemporary and repositionable mountingVSAvoidattachment security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent employs curved or contoured retaining plate designs that conform to the cylindrical shape of wires, ropes, or poles. This curvature adaptation allows the retainers to maintain secure contact and prevent lateral shifting while preserving the temporary and repositionable nature of the mounting system.

Inventive Principle:

Principle #14Spheroidality (Curvature)

4Adaptability or versatility

If conventional mounting methods are used on non-walled structures, then articles can be hung, but the presentation is insecure

Engineering Contradiction:

Improvemounting on diverse surfacesVSAvoidattachment security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent creates a universal mounting system where ferromagnetic retaining plates can be attached to any ferromagnetic surface (walls, poles, wires, fences, vehicles) and magnetic retainers provide consistent secure attachment across all these diverse substrates. This multi-functionality resolves the contradiction between versatility and security.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A magnetic hanging system is disclosed herein. The magnetic hanging system includes a plurality of retainers and one or more plurality of retaining plates. The retaining plates are ferromagnetic, and the retainers include an attachment surface that attracts and secures the retaining plate (or another ferromagnetic surface) to the retainer. A retainer may comprise a retaining base and a retaining top. The magnetic base includes the base attachment surface that includes a base magnet that attracts and secures the retainer to a ferromagnetic surface. The retaining base also includes a base securing feature. The retaining top includes the top and a top securing feature. portion. The retainer is configured for securing at least a portion of the article by connecting the top securing feature to the bottom securing feature through a securing hole in the to-be-hung article.
