Jewelry Clasp Concealment via Nested Ingot Charm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jewelry clasps often lack both security and aesthetic appeal, as they can be unsightly and prone to misalignment due to voids or hollow areas, which can make them difficult to use and less appealing.
Innovation Solution
A clasp design that features a main body and tongue configuration, where the tongue is received by a through-hole in the main body, forming a secure and space-filling flat surface when engaged, allowing for easy and secure coupling while appearing as a charm or ingot, thus hiding the clasp aesthetically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional clasp mechanisms (ball clasp, barrel clasp, lobster clasp, etc.) are used, then the jewelry can be easily opened and closed, but the clasp appears unsightly and compromises the aesthetic appearance of the jewelry
Solution Approach 1:
The clasp mechanism is extracted from the visible portion of the jewelry and concealed within a hollow cavity of an ingot-shaped charm. The tongue extends through a through-hole in the ingot body, allowing the clasp to function while remaining hidden inside the charm housing, thus eliminating the visual impact of traditional clasps.
Solution Approach 2:
The clasp components (main body and tongue) are nested within the hollow cavity of the ingot charm. The main body is received by the hollow cavity, and the tongue passes through the through-hole, creating a nested structure where the functional clasp mechanism is contained within the decorative charm.
2Device complexity
If traditional clasp mechanisms with voids or hollow areas are used, then the clasp can be simplified in structure, but the voids cause misalignment of moving parts and make the clasp difficult to use
Solution Approach 1:
The through-hole in the ingot body provides a localized guided path for the tongue, ensuring proper alignment. The hollow cavity provides localized space for the main body, allowing simplified structure while maintaining correct positioning through the constrained geometry of the through-hole and cavity interface.
3Device complexity
If the clasp is made visible as a separate component, then the coupling mechanism can be simplified, but it disrupts the balance and aesthetic of the jewelry item
Solution Approach 1:
The clasp mechanism is merged with the ingot charm by housing the main body within the charm's hollow cavity and having the tongue pass through the charm's through-hole. This integration makes the clasp appear as part of the charm itself, maintaining jewelry balance and aesthetics while keeping the coupling mechanism relatively simple.

AI summary
The inventive disclosures described herein pertains to an improved clasp-type device for connecting two ends of a wrap-around personal-adornment/jewelry item, such as a necklace, bracelet, or anklet. The improved jewelry clasp provides for both easy and secure coupling of two ends of a wrap-around jewelry item, while providing a decorative “hiding” of the clasp. In variations, the improved jewelry clasp can appear as just one of several ingots/charms that the wrap-around jewelry item may contain. Various other practical applications of the improved jewelry clasp are also disclosed.
