Nested Jewelry Ring Assembly with Asymmetric Anti-Rotation Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rings tend to rotate on the wearer's finger, causing the gemstone or head to face the side of the finger, which can be uncomfortable and aesthetically undesirable, especially when multiple rings are worn.
Innovation Solution
A jewelry system comprising an outer ring and an inner ring, where the inner ring fits within the outer ring and features protrusions at 5 o'clock and 7 o'clock positions to prevent rotational movement, aligning both rings and keeping the gemstone facing the dorsal side of the hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single ring is worn on a finger, then the ring can be easily manufactured and worn, but the ring tends to rotate about the finger causing the gemstone to face the side or bottom of the finger
Solution Approach 1:
The patent applies the nesting principle by placing an inner ring inside an outer ring, creating a nested structure where the inner ring fits within the aperture of the outer ring. This nested configuration provides rotational stability while maintaining ease of wearing, as the combined structure acts as a single unit on the finger.
Solution Approach 2:
The patent employs asymmetry through the protrusions on the inner ring that are positioned at specific angular locations (5 o'clock and 7 o'clock positions). These asymmetric protrusions engage with corresponding features on the outer ring to prevent rotation, while the overall design maintains aesthetic symmetry when viewed from the front.
2Adaptability or versatility
If multiple rings are worn on the same finger, then fashion expression and style can be enhanced, but the rings become misaligned and uncomfortable
Solution Approach 1:
The nested ring structure allows multiple rings to be worn in a coordinated manner, with the inner ring fitting within the outer ring. This configuration maintains alignment between rings and provides comfort by creating a unified structure that moves together on the finger, while still allowing for fashion expression through different ring designs.
3Ease of manufacture
If the inner ring is freely movable within the outer ring, then the rings can be easily assembled and disassembled, but the inner ring rotates causing misalignment of the heads
Solution Approach 1:
The patent uses asymmetric protrusions positioned at specific angular locations (5 o'clock and 7 o'clock) on the inner ring to engage with corresponding features on the outer ring. This asymmetric arrangement prevents rotation and maintains head alignment, while the overall design remains simple enough for easy assembly and disassembly.

AI summary
A jewelry system includes an outer ring having an open shank and an aperture on either side of the shank, and an inner ring configured to be received within an aperture of the outer ring such that the outer ring and the inner ring are removably coupled to one another. The inner ring includes extending surfaces or protrusions at side points on opposite sides of its shank, near the base of the shank, which are configured to be seated within the apertures in the outer ring. The extended surfaces are located at approximately 5 o'clock and 7 o'clock on the inner ring and are configured prevent the movement of the inner ring with respect to the outer ring while the inner ring is coupled to the outer ring.
