Solution Overview

Problem

Large diamonds are expensive due to non-linear pricing, making them costly to purchase and set in jewelry, and existing methods do not effectively reduce the expense while maintaining visual appeal.

Innovation Solution

A method for cutting and setting multiple Princess Cut Diamonds to create the appearance of a larger diamond, involving increasing the table size, repositioning the culet, and arranging them to resemble a single large diamond, which reduces material costs and weight while maintaining visual appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single large diamond is used, then the visual appeal and size are improved, but the cost increases exponentially due to non-linear pricing

Engineering Contradiction:
Improvediamond sizeVSAvoidcost
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The patent divides a single large diamond into multiple smaller princess-cut diamonds (typically four stones) that are arranged and set together to create the visual appearance of a larger diamond. This segmentation allows the total carat weight to be distributed across multiple smaller stones, significantly reducing the exponential cost associated with a single large diamond while maintaining the desired visual impact and size perception.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If multiple smaller diamonds are used instead of one large diamond, then the cost is reduced, but the visual appeal and perceived size may be compromised

Engineering Contradiction:
ImprovecostVSAvoidvisual size
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent combines multiple smaller princess-cut diamonds into a unified setting where they are arranged in a specific configuration (such as a 2x2 grid) and set closely together with minimal spacing. This merging approach creates the visual illusion of a single large diamond, as the individual stones blend together to form a continuous surface area that appears larger and more substantial than the sum of its parts would suggest.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent utilizes the spatial arrangement and dimensional configuration of multiple diamonds to create visual depth and perceived size. By arranging the stones in a specific three-dimensional setting with careful attention to height, spacing, and orientation, the design creates optical illusions that enhance the perceived size and grandeur of the overall piece, compensating for the use of multiple smaller stones rather than one large diamond.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Area of stationary object

If the table size is increased to enhance visual appeal, then the diamond appears larger, but the girdle facets become shorter and the structural integrity may be affected

Engineering Contradiction:
Improvetable sizeVSAvoidgirdle facet length
Core Design Contradiction:
Area of stationary objectVSLength of stationary object

Solution Approach 1:

The patent modifies the traditional princess-cut diamond parameters by increasing the table size relative to the overall diamond dimensions. This parameter change enhances the visual appeal and perceived size of each individual diamond in the cluster. The cutting process is adjusted to create a larger table while相应地 adjusting the girdle facet lengths and crown angles to maintain structural integrity and proper light reflection properties.

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If the culet is repositioned away from the center to achieve seamless appearance, then the visual continuity is improved, but the symmetry and traditional aesthetic are altered

Engineering Contradiction:
Improveseamless appearanceVSAvoidsymmetry
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

The patent deliberately introduces asymmetry by repositioning the culet away from the traditional center position in each princess-cut diamond. This asymmetric modification is designed to create seamless transitions between adjacent diamonds in the cluster, eliminating visible lines or gaps that would disrupt the overall visual continuity. The asymmetric culet positioning allows the facets of adjacent stones to align more smoothly, creating a unified appearance that prioritizes visual continuity over traditional symmetric aesthetics.

Inventive Principle:
Principle #4Asymmetry

AI summary

Presented herein is a diamond comprising a table, a crown, a girdle, a pavilion, and a culet. The table is rectangular, having a length and a width. The table includes a first side, adjacent to a second side, adjacent to a third side, and adjacent to a fourth side. The first side of the table is directly connected with a first facet of the girdle. The second side of the table is directly connected with a second facet of the girdle. The crown includes a plurality of facets connecting the third side and the fourth side of the table to the girdle. The pavilion is connected to the girdle. The culet is positioned directly below a point having a 1% deviation from the center of the girdle.
