Jewelry Stone Setting With Shifting Prong
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional prong settings for jewelry stones conceal the stone from view due to multiple prongs and their base attachment, which obstructs maximum visibility.
Innovation Solution
A single ring setting with a shifting prong that secures the stone from above, connected to the jewelry base on one point, allowing maximum exposure while maintaining reliable fixation, suitable for stones of any cut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple prongs are used to secure the stone, then the fixation reliability is improved, but the stone visibility is worsened due to concealment in more than two places
Solution Approach 1:
The setting divides the fixation function into two separate elements: a ring that provides base support and a single prong that provides pin-point securing. This segmentation allows each element to perform its specific function optimally while minimizing overall concealment compared to multiple prongs.
Solution Approach 2:
The invention extracts the base attachment function from the prongs themselves and places it in a separate ring element. This separates the support function (ring) from the securing function (prong), allowing the prong to be positioned optimally for visibility while the ring handles the base attachment.
2Reliability
If multiple prongs are used to secure the stone, then the fixation reliability is improved, but the device complexity is worsened
Solution Approach 1:
The setting is segmented into two distinct functional elements (ring and prong) rather than using multiple similar prongs. This reduces complexity by using fewer, more specialized elements while maintaining the required fixation reliability through the coordinated action of the two segments.
Solution Approach 2:
The ring and prong are merged into a single integrated setting assembly that works together to secure the stone. This combining of two elements achieves the same fixation reliability as multiple prongs while reducing overall structural complexity.
3Reliability
If prongs are attached to the base at multiple points, then the fixation reliability is improved, but the stone exposure is worsened
Solution Approach 1:
The base attachment function is extracted from the prongs and placed in a separate ring element. This allows the prong to be positioned to minimize concealment while the ring handles the base attachment, maximizing the exposed area of the stone.
Solution Approach 2:
Instead of having prongs attach directly to the base at multiple points, the invention inverts the approach by having a ring attach to the base and a single prong extend from the ring to secure the stone. This inversion allows for maximum stone exposure while maintaining fixation reliability.

AI summary
The invention is designed for use in the jewelry industry. A setting for stones of any type of cut in jewelry manufacturing comprises a ring, having a form corresponding to the lower part of the stone being set, connected to the base of the piece of jewelry in two places, and one prong. The prong is connected to the base of the jewelry product in one place at the top part and configured to enable fixation of the stone at a point on the ring after positioning it on the top part. This ensures reliability and simplification of stone fixation in the jewelry product and maximum concealment of the stone from view.
