Pierced Earring Jump Rings for Three-Axis Decorative Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ornaments, such as pierced earrings and necklaces, face challenges in emphasizing the beauty of their decorative components and require a simpler and more diverse dangling mechanism.
Innovation Solution
The ornament features a first and second jump ring with tapered cross-sections forming a point contact, allowing the second jump ring to dangle about three orthogonal axes, enhancing the aesthetic appearance and durability of the dangling motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a double-ring mechanism with coupling portions is used, then the decorative element can dangle, but the dangling motion is limited to about a single imaginary-rotation axis
Solution Approach 1:
The invention divides the dangling mechanism into multiple independent jump rings (first jump ring and second jump ring) that can rotate relative to each other about different axes. The first jump ring rotates about a first imaginary-rotation axis while the second jump ring rotates about a second imaginary-rotation axis, allowing multi-axis dangling motion without requiring a complex integrated mechanism.
Solution Approach 2:
The invention transitions from single-axis rotation to multi-axis rotation by arranging jump rings in sequence along the dangling path. The first jump ring provides rotation about one axis, while the second jump ring adds rotation about another axis, effectively adding dimensional freedom to the dangling motion in a simple additive manner.
2Adaptability or versatility
If the cross-sectional shape of jump rings is changed to tapered shape, then the inner periphery can be linked in point contact, but manufacturing precision requirements increase
Solution Approach 1:
The invention applies a tapered cross-sectional shape specifically to the inner periphery portions of the jump rings where point contact is required, while other portions of the jump rings can have standard cylindrical cross-sections. This localized application of the tapered shape achieves the necessary point contact capability without requiring the entire jump ring structure to be manufactured with high precision.

AI summary
Provided is a pierced earring that has a simple configuration and that is capable of further emphasizing beauty of its decorative component. A first jump ring (21) of a distance adjustment member (17) is provided. A second jump ring (23) is engaged with the first jump ring (21). A cross-section of the first jump ring (21) and a cross-section of the second jump ring (23) are each formed in a tapered shape that protrudes at a distal angle of 60° to 90° to an inner side. With this, an inner periphery of the first jump ring (21) and an inner periphery of the second jump ring (23) are linked in point contact to each other. This allows the second jump ring (23) to dangle about a Z-axis, an X-axis, and a Y-axis (three axes) relative to point-link portions (41) in the point contact.
