Jewelry Extender with Ring Fastener for Secure Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Jewelry articles often fall off wearers due to loosening knots or failed fasteners, necessitating additional security measures that do not compromise their appearance.
Innovation Solution
A jewelry article design featuring a main segment, extender, and ring with a fastener that creates a variable circumference loop, where the fastener is larger than the ring opening, allowing for adjustable and secure attachment to the extender or ring, preventing accidental detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional fastener or knot is used to close the jewelry article, then the article can be worn around the body part, but the fastener or knot may loosen over time or fail, causing the jewelry to fall off
Solution Approach 1:
The jewelry article is divided into distinct segments: a main segment with a fastener, an extender segment with multiple links, and a ring component. This segmentation allows the fastening function to be separated from the decorative chain, enabling reliable attachment while maintaining the aesthetic appearance of the jewelry.
Solution Approach 2:
The extender segment is designed to pass through the ring, creating a nested configuration where the extender is partially contained within the ring structure. This nesting provides mechanical constraint that prevents accidental detachment while allowing the extender to be pulled through for adjustment or removal.
2Reliability
If the fastener is made larger to prevent it from passing through the ring opening, then security is improved, but the appearance may be compromised
Solution Approach 1:
The fastening function is extracted from the main decorative portion of the jewelry and concentrated in a dedicated fastener component. This allows the fastener to be optimized for security (larger size, robust construction) while being visually separated from the main jewelry design, minimizing its aesthetic impact.
Solution Approach 2:
The ring serves as an intermediary element between the main segment and the extender/fastener assembly. It provides a structural interface that constrains the fastener while maintaining the overall aesthetic design of the jewelry, allowing the fastener to be functional without dominating the visual appearance.
3Adaptability or versatility
If the jewelry article uses a fixed circumference design, then the structure is simple, but it cannot accommodate variable body part sizes or provide adjustable fit
Solution Approach 1:
The jewelry article transitions from a fixed circumference design to a dynamic, adjustable structure. The extender segment can be pulled through the ring to adjust the circumference, and the fastener can be attached at different positions on the extender to create variable loop sizes, enabling adaptation to different body part sizes and preferences.

AI summary
A jewelry article is disclosed. The jewelry article includes a main segment configured to loop around a body part and having a first and second end. A ring with a center opening is attached to the second end of the main segment. An extender has a first and second end, wherein the first end of the main segment is attached to the second end of the extender and the first end of the extender passes through and extends beyond the center opening of the ring, providing a variable circumference loop. The jewelry article further includes a fastener attached to the first end of the extender, wherein the fastener is larger than the opening of the ring and cannot pass therethrough, and the fastener is configured for removeable connection to the extender or the ring. Methods of securing the jewelry article around a body part are also disclosed.
