Necklace Keeper Clasp With Sliding Lock Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional necklace clasps are difficult to manipulate, making them complex and hard to operate effectively for securing necklace ends and charms.
Innovation Solution
A necklace clasp design featuring a support ring with a gap, a top head piece, a sliding lock pad biased by a coil spring, and a guide ring with a U-shaped channel, allowing for easy engagement and release to secure charms, with the sliding lock pad inhibiting relative rotation in the locked position and enabling alignment of gaps for rotation in the released position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional clasps are used, then necklace ends can be secured, but the clasps are difficult to manipulate and operate
Solution Approach 1:
The clasp is divided into separate functional components: a support ring with gap for necklace passage, a sliding lock pad with spring for securing, and a guide ring with channel for alignment. This segmentation allows each component to perform its specific function independently, improving ease of operation while maintaining security.
Solution Approach 2:
The lock pad is designed to slide dynamically between locked and unlocked positions, controlled by spring bias. This dynamic mechanism allows easy manipulation - the user simply slides the lock pad to engage or disengage the necklace, transforming a complex manual manipulation into a simple linear motion.
2Ease of operation
If a sliding lock pad with spring is used, then the clasp becomes easier to operate, but the device complexity increases
Solution Approach 1:
The spring-loaded lock pad automatically returns to its locked position after being slid to the unlocked position. The spring provides self-return functionality, eliminating the need for manual manipulation to return the lock pad to its starting position. This self-service mechanism simplifies operation while adding only a single spring component.
Solution Approach 2:
The support ring and guide ring structure serves multiple functions: providing structural support, guiding the necklace passage, and enabling the sliding lock mechanism. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity despite adding the spring-loaded lock pad.

AI summary
A necklace keeper or clasp for securing a jewelry item and for receiving one or more charms. The clasp includes a support member constructed of a support ring that extends less than a full circle so as to define a support ring gap, and a top head piece that extends upwardly from the support ring. A sliding lock pad engages with the top head piece and is normally biased to an extended position. A guide ring is providing having a channel for receiving a support ring and extending less than a full circle so as define a guide ring gap. The sliding lock pad has a lock position in which it engages the support ring to inhibit relative rotation between the support ring and the guide ring; and has a release position in which there is relative rotation between the support ring and the guide ring so that the respective supporting ring gap and guide ring gap each align.
