Magnetic Pocket Closure Structure to Prevent Object Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pockets in garments suffer from low reliability due to non-removable seams that can rupture, and they fail to prevent small objects from falling out or getting jammed, with closures potentially turning inside out.
Innovation Solution
A pocket design featuring edge elements made of dense fabric with integrated magnets, reinforced with additional stitching and a reinforcing layer, and a removable zipper for easy closure, ensuring secure and reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If non-removable seams are used to connect pocket elements, then the pocket structure is simple and easy to manufacture, but the reliability is low and the material integrity is lost when damaged
Solution Approach 1:
The pocket is divided into separate elements (front wall, back wall, closure) that can be independently manufactured and then assembled using removable magnetic fasteners instead of permanent seams. This segmentation allows each component to be optimized independently while maintaining overall reliability through removable connections that prevent material rupture.
2Device complexity
If traditional closure elements are used, then the pocket structure is simple, but small objects can fall out or get jammed and the closure may turn inside out
Solution Approach 1:
The closure element integrates multiple functions into a single component: it closes the pocket opening, prevents small objects from falling out through its extended lower edge, and the magnetic fastener system prevents the closure from turning inside out. This merging of functions maintains simplicity while significantly improving reliability.
Solution Approach 2:
The closure element is designed with a lower edge that extends beyond the pocket opening to proactively prevent small objects from falling out. The magnetic fastening system also preemptively prevents the closure from turning inside out by creating a secure magnetic bond that resists such deformation.
3Ease of operation
If magnetic fasteners are integrated into the closure, then the pocket becomes easier to use, but the manufacturing complexity increases
Solution Approach 1:
The traditional mechanical sewing system is replaced with a magnetic fastening system. The magnetic fasteners provide easy open/close operation through magnetic attraction and repulsion, eliminating the need for complex mechanical fastenings or repeated sewing operations. This substitution significantly improves ease of use while the modular nature of magnetic fasteners keeps manufacturing complexity manageable.

AI summary
The proposed invention relates to details of garments and can be used in various garments, including jackets, trousers and skirts, preferably for everyday wear, and can furthermore be used in garments that have pockets with a substantially vertical or inclined opening, as well as in bags. The claimed pocket is formed from a lining, the material of which is made up either of the main fabric of the article and/or of a lining fabric. The pocket can be formed from a single panel of lining folded along a fold line, or from at least two interconnected parts that make up the walls of the pocket and form the interior cavity (volume) of the pocket. The lining can be single-layered or multi-layered.
