Garment Closure with Rotating Bar and Nylon Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closures for reversibly securing two items are not sufficiently secure and do not provide a reliable mechanism for repeated attachment and detachment.
Innovation Solution
A closure mechanism comprising a male closure member with a first loop, an arm, and a bar, and a female closure member with a second loop, a base portion, and protrusions, which work together to provide secure reversible attachment through a blind hole and recess configuration, with optional nylon coating for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing closure mechanisms are used, then the closure can be opened and closed, but the securement reliability is insufficient for repeated attachment and detachment
Solution Approach 1:
The closure is divided into separate male and female members, each with specific functional elements (bar with arm, blind hole with protrusions). This segmentation allows each component to be optimized for its specific function while working together to provide reliable securement through defined engagement geometry.
Solution Approach 2:
The bar is inserted into the blind hole, with the arm nesting within the recess formed by the protrusions. This nested configuration ensures proper alignment and provides multiple contact points for secure engagement, enhancing reliability through geometric interlocking.
2Duration of action of stationary object
If the closure mechanism uses additional coating and structural elements, then the durability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The closure combines metal or plastic base materials with a nylon coating layer. This composite structure provides the mechanical strength and form of the substrate while the nylon coating adds wear resistance and durability, extending the service life of the closure components.
Solution Approach 2:
The nylon coating is applied to specific portions of the male or female closure members where wear occurs during engagement and disengagement. This localized treatment provides enhanced durability at critical contact points without requiring complete coating of all surfaces, balancing manufacturing complexity with performance benefits.

AI summary
A garment and associated closure including a male closure member including a first loop, an arm, and a bar; a female closure member including a second loop and a base portion including a top edge, a bottom edge, a blind hole into which the bar of the male closure member is insertable at the top edge and moveable along and configured for rotational pivoting of the bar in the blind hole, a recess configured to receive the arm of the male closure member upon rotational pivoting of the bar in the blind hole, and two protrusions extending from the recess and configured to reversibly secure the arm of the male closure member between the two protrusions upon rotational pivoting of the bar in the blind hole; and a nylon coating disposed on at least a portion of the male closure member or the female closure member.
