Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional diamond cutting methods are used, then the manufacturing process is simple, but the brilliance and visual effect are insufficient
Solution Approach 1:
The diamond is divided into 81 precisely calculated facets, including 24 crown facets, 33 pavilion facets, and 24 girdle facets. This segmentation allows each facet to be optimized for specific light interaction, creating the ten hearts and ten arrows effect while maximizing brilliance through controlled light refraction and reflection paths.
Solution Approach 2:
Different regions of the diamond are given different facet characteristics. The crown portion has facets optimized for light entry and initial refraction, the pavilion has facets designed for total internal reflection and light return, and the girdle has facets that bridge these functions. Each local region is tailored to its specific optical function to achieve overall superior brilliance.
2Illumination intensity
If the number of facets is increased to create complex inner structures, then the brilliance is improved, but the manufacturing precision requirement increases
Solution Approach 1:
The patent provides comprehensive preliminary guidance for achieving the desired optical effects, including specific angle ranges for different facet configurations (e.g., crown facets at 34-35 degrees to the girdle, pavilion facets at 40.5-40.8 degrees). These pre-calculated parameters guide the cutting process to achieve consistent results while managing the complexity of creating 81 facets.
Solution Approach 2:
The invention optimizes multiple geometric parameters simultaneously, including facet angles, facet sizes, crown height (14.5-15.5% of diameter), pavilion depth (43.5-45% of diameter), and table size (56-57% of diameter). By carefully adjusting these parameters within specific ranges, the design achieves the ten hearts and ten arrows effect while maintaining manufacturability.
3Measurement precision
If precise facet angles and proportions are implemented, then the ten hearts and ten arrows effect is achieved, but the difficulty of detection and measurement increases
Solution Approach 1:
The patent establishes clear verification criteria for the ten hearts and ten arrows effect, providing measurable standards for assessing whether the cutting has been successful. These include specific angle tolerances and visual inspection guidelines that allow craftsmen and quality control personnel to verify the inner structure precision without requiring overly complex measurement equipment.
