Garment Magnetic Carrier with Distributed Load Patch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for carrying personal items, such as bags and pockets, are restrictive, prone to loss, and limited in capacity and accessibility, with existing wearable pockets facing challenges like difficult access and garment distortion due to single magnetic contact points.
Innovation Solution
A magnetically attachable carrier system using a flexible, magnetically active patch that can be attached to the inner side of a garment, allowing personal items or holders to be securely carried on the outer side, distributing load and maintaining garment flexibility, with options for various attachments and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single magnetic contact point is used to attach the pocket to the garment, then the attachment is simple and the magnetic force is concentrated, but the garment experiences distortion and creases due to concentrated load
Solution Approach 1:
The magnetic attachment system is divided into multiple discrete magnets distributed across the patch and button surfaces. Instead of a single magnetic contact point, multiple magnets are arranged in arrays, which segments the magnetic force into multiple contact points. This segmentation distributes the mechanical load across multiple locations on the garment, preventing concentrated stress that causes distortion and creases.
Solution Approach 2:
The magnetic strength and distribution are optimized locally at different positions. Magnets are strategically placed and sized to create varying local magnetic field strengths, with stronger fields at edges and weaker fields toward the center. This local quality variation ensures uniform pressure distribution across the garment surface while maintaining secure attachment, preventing both distortion and slippage.
2Reliability
If the button is rigid and attached from the outside while the pocket is worn inside, then the magnetic attachment is secure, but the access to the pocket is difficult
Solution Approach 1:
The conventional arrangement is inverted: instead of having the rigid component on the outside and the flexible component on the inside, the flexible patch with magnets is placed on the outside surface of the garment where it can be easily accessed. The button with magnets remains on the inside of the pocket. This inversion allows the pocket opening to face outward, making items easily accessible while maintaining secure magnetic attachment through the garment fabric.
3Shape
If magnets are disposed at considerable distance from one another in the patch, then the load is distributed over a larger area of the garment, but the magnetic holding force may be reduced
Solution Approach 1:
The magnetic system parameters are optimized by varying magnet size, spacing, and strength distribution. Larger magnets with moderate spacing provide both load distribution and sufficient holding force. The magnetic field strength is adjusted by selecting appropriate magnet materials and dimensions, ensuring that even with increased spacing for load distribution, the cumulative holding force remains adequate for securing the pocket and its contents.
Applied Scientific Principles
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 convenient, accessible, and load-distributed carrying of personal items on any part of a garment, maintaining flexibility and reducing the risk of loss, while allowing for easy attachment and removal of items without distorting the garment.
Implementation Method 1
a magnetically active member, designed to hold personal articles - either by themselves or within a holder - attached to the garment; it is magnetically active owing to one or more magnets included therein
Implementation Method 2
an anchor member, attachable to the outer side of the garment and including a ferromagnetic part configured to be magnetically attracted by at least one of the magnets and to thereby secure the patch in place

AI summary
There is provided a carrier, for carrying one or more personal articles on any part of a garment, comprising a patch, configured to be temporarily attachable to the inner side of the garment and including one or more magnets, configured to hold attached to the outer side of the garment at least one article or articles holder that may be attracted magnetically. There are also provided holders, each formed to hold one or more of the articles and configured to be temporarily attachable to the outer side of the garment and to be magnetically attracted to any of the magnets. Any of the holders may include one or more magnets, configured to be attracted to corresponding magnets in the patch. Any of the holders may be formed as a pouch or a pocket.
