Solution Overview

Problem

There is a need for an efficient and effective method to cut gemstones that provides a brilliant reflective cut, as existing methods do not adequately enhance the reflective properties of gemstones through facet arrangement and angle.

Innovation Solution

The proposed solution involves a specific arrangement of facets on a gemstone, including a crown with eight star sets, eight bezel facets, and eight pairs of upper girdle facet sets, with additional secondary facets to create stronger reflective lines and enhance light reflection, such as adding narrow rectangular secondary facets adjacent to primary facets and triangular secondary facets, resulting in a higher number of brilliandeering facets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional facet cutting methods are used, then the cutting process is simpler, but the reflective brilliance and light reflection are insufficient

Engineering Contradiction:

Improvereflective brillianceVSAvoidfacet arrangement complexity

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The gemstone crown is divided into multiple distinct facet groups: star facets (8-16 facets), bezel facets (8 facets), and upper girdle facets (16-32 facets). Each group serves a specific optical function and is arranged in systematic patterns around the table, creating enhanced light reflection through segmented structural organization

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different facet groups are positioned at specific locations with predetermined angles relative to the table and girdle. Star facets are arranged in radial patterns, bezel facets form circular patterns, and upper girdle facets create additional reflective lines, with each location optimized for its specific reflective function

Inventive Principle:

Principle #3Local quality

2Illumination intensity

If more facets are added to enhance brilliance, then light reflection improves, but the cutting process becomes more complex

Engineering Contradiction:

Improvelight reflectionVSAvoidcutting process ease

Core Design Contradiction:

Illumination intensityVSEase of manufacture

Solution Approach 1:

The patent establishes predetermined angle relationships between facet groups and the table-girdle axis before cutting begins. Star facets are set at specific angles (e.g., 30-45 degrees), bezel facets at predetermined angles, and upper girdle facets with defined angle ranges, allowing cutters to follow systematic guidelines rather than perform complex real-time calculations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention specifies parameter ranges for facet angles (e.g., star facets at 30-45 degrees, bezel facets at predetermined angles, upper girdle facets with defined ranges) that optimize light reflection while providing flexible manufacturing tolerances, balancing optical performance with cutting feasibility

Inventive Principle:

Principle #35Parameter changes

3Illumination intensity

If facet angles are increased to create stronger reflective lines, then brilliance enhancement improves, but the structural stability may be compromised

Engineering Contradiction:

Improvereflective line strengthVSAvoidstructural stability

Core Design Contradiction:

Illumination intensityVSStability of the object's composition

Solution Approach 1:

The patent defines specific angle ranges for different facet groups (star facets: 30-45 degrees, bezel facets: predetermined angles, upper girdle facets: defined angle ranges) that optimize reflective line strength while maintaining structural integrity through balanced geometric relationships

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The facet arrangement creates asymmetric reflective patterns with star facets radiating from the center, bezel facets forming circular patterns, and upper girdle facets adding additional reflective lines, producing pronounced brilliance effects through non-uniform light distribution while maintaining overall structural symmetry

Inventive Principle:

Principle #4Asymmetry
