Magnetic Zipper Holder Structure for Preventing Unintended Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zipper designs with loop-shaped cords are prone to unintended opening or closing due to external contact, posing safety and convenience issues.
Innovation Solution
A zipper holding device with a holder and engaging member that securely attaches to a zipper, using magnets and locking portions to prevent the cord from being pulled upward, maintaining the locked state and preventing unintended operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a loop-shaped cord is connected to the zipper handle, then convenience of use is improved, but the cord can easily get caught by external objects or body movement causing unintended opening or closing
Solution Approach 1:
The cord is divided into two functional segments: a loop-shaped portion for user interaction and a tapered portion for secure engagement with the holder. This segmentation allows the cord to maintain ease of operation while preventing unintended opening through the tapered engagement mechanism
Solution Approach 2:
The tapered portion of the cord is designed to preliminarily resist external forces before the zipper can be unintentionally opened. The tapering geometry creates a mechanical barrier that prevents the cord from being caught by external objects, thereby preemptively protecting against unintended opening
2Ease of operation
If the loop-shaped cord remains exposed, then ease of attachment is improved, but unintended opening or closing may occur due to contact with external objects
Solution Approach 1:
The tapered portion of the cord is nested within the holder structure, creating a protected engagement zone. This nesting arrangement allows the cord to remain accessible for attachment while being protected from harmful external contact through the holder's structural enclosure
3Reliability
If the cord is secured to prevent unintended operation, then reliability is improved, but the structure becomes more complex
Solution Approach 1:
The holder acts as an intermediary component between the cord and the zipper mechanism. This intermediary structure provides a simple yet effective solution by creating a mechanical barrier that prevents the cord from being pulled, thereby securing the locked state without requiring complex locking mechanisms
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
The device ensures the zipper remains securely locked, providing ease of use and maintaining an aesthetically pleasing appearance by neatly fixing the cord and engaging member, while preventing unintended opening.
Implementation Method 1
an engaging member (40) including a chamber (41) formed therein, the chamber being configured to house a first magnet (M1),... a second magnet (M2) embedded in a bottom surface of the seating surface (31)

AI summary
A zipper holding device includes: an engaging member including a chamber formed therein, the chamber being configured to house a first magnet, the chamber having an inlet and an outlet formed at opposite sides thereof, wherein the outlet is tapered to gradually narrow toward the exterior; and a holder including a seating surface configured to receive the engaging member, a pair of support portions protruding from both sides of the seating surface, a plate-shaped fixing portion formed along an outer edge of the seating surface, and a second magnet embedded in a bottom surface of the seating surface. The pair of support portions are gradually bent inward toward a front end to form an opening, and locking portions are formed at an upper side of the opening protruding toward each other.
