Magnetic Bag Closure Mechanism With Concealed Rotating Latch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closure devices for bags and clothing are aesthetically unattractive due to visible rotating parts, affecting the overall appearance of the item, and lack integration with the design.
Innovation Solution
A closure device with a rotatable movable part hinged to a fixed part using magnetic return means, featuring contoured cavities and engagement teeth, allowing seamless integration with the item's design and ensuring reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional closure device with visible rotatable parts is used, then the closure function is achieved, but the aesthetic appearance of the bag is degraded
Solution Approach 1:
The movable part is designed to nest within or align with the fixed part when in the closed position, causing the engagement tooth to be concealed within the contoured cavity. This nesting arrangement allows the closure mechanism to perform its function while remaining visually integrated with the bag's design.
Solution Approach 2:
The engagement tooth and contoured cavity are designed to merge visually when engaged, creating a seamless appearance. The contoured cavity is shaped to accommodate and visually blend with the engagement tooth, making the closure mechanism indistinguishable from the overall design of the bag.
2Ease of operation
If the movable part is made visible and distinct, then the operation mechanism is clear, but the integration with the bag design is lost
Solution Approach 1:
The movable part is designed with specific local qualities - the engagement tooth is shaped and positioned to engage precisely with the contoured cavity, providing clear tactile feedback for operation. Meanwhile, the overall form and material of both parts are matched to blend seamlessly with the bag's design, achieving both operational clarity and aesthetic integration.
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 provides a visually integrated closure mechanism that maintains reliability and efficiency while being cost-effective to produce, enhancing the aesthetic appeal of bags and clothing.
Implementation Method 1
automatic return means for returning the movable part to the engagement position

AI summary
A closure device (1), particularly for bags and items of clothing in general, which comprises a fixed part (2) associable with a first flap (3) of a bag or item of clothing in general and a movable part (4) which is associated with the fixed part (2) and is engageable with a second flap (5) of the bag or item of clothing in general so as to provide a closure between the flaps (3, 5) as a result of their overlap; the movable part (4) has an engagement tooth (6 upper plate (16) which is associable with the second flap (5); the fixed and movable parts (2, 4) are hinged to each other so as to ensure that the movable part (4) is rotatable with respect to the fixed part (2) about an axis of rotation (8) between an engagement position, in which the movable part (4) is superimposed on the fixed part (2) and in which the engagement tooth (6) is engaged with the contoured cavity (7), and a release position, in which the movable part (4) is rotated with respect to the engagement position and in which the engagement tooth (6) is disengaged from the contoured cavity (7).
