Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dimple patterns and construction parameters are used, then manufacturing is simpler, but aerodynamic performance and flight consistency deteriorate
Solution Approach 1:
The golf ball surface is segmented into multiple dimple zones with different characteristics (first dimple zone with larger dimples, second dimple zone with smaller dimples). This segmentation allows each zone to contribute differently to aerodynamic performance, improving flight consistency through optimized drag and lift characteristics across various flight phases.
Solution Approach 2:
Different regions of the golf ball surface are given different local qualities through varying dimple sizes, depths, and distributions. The first dimple zone has larger dimples for initial flight stability, while the second dimple zone has smaller dimples for sustained flight control. This local differentiation optimizes aerodynamic performance without requiring complete redesign of the entire surface.
2Reliability
If optimized dimple patterns are implemented, then aerodynamic performance improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies ranges for dimple parameters (sizes, depths, distributions) rather than exact values, allowing for manufacturing tolerances. The optimized aerodynamic performance is achieved through maintaining parameters within specified ranges rather than requiring precise control at single values, thus balancing performance optimization with manufacturing feasibility.
3Reliability
If weight and diameter are optimized for aerodynamic performance, then flight control improves, but compliance with standard golf ball specifications becomes difficult
Solution Approach 1:
The patent optimizes weight and diameter as continuous parameters within acceptable ranges (weight: 1.600-1.620 ounces, diameter: 1.680-1.700 inches) rather than fixed values. This allows the golf ball to maintain standard specification compliance while achieving optimized aerodynamic performance through precise parameter control within these ranges.
