Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dimple patterns are used, then manufacturing is simple, but aerodynamic performance is not optimized
Solution Approach 1:
The patent applies local quality by creating different dimple types (first, second, and third dimples) with varying depths, diameters, and distributions across different regions of the golf ball surface. This localized variation optimizes aerodynamic performance in specific flight conditions while maintaining overall ball performance.
Solution Approach 2:
The patent employs parameter changes by systematically varying dimple depth, diameter, spacing, and distribution patterns to achieve desired drag and lift coefficients. The dimple parameters are optimized across different Reynolds numbers and spin ratios to enhance flight characteristics.
2Reliability
If multi-layered construction is added, then aerodynamic performance is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the golf ball into multiple functional layers (core, intermediate layers, and cover) with the dimple pattern integrated into the cover layer. This allows independent optimization of each layer's properties while simplifying the manufacturing process through modular construction.
Solution Approach 2:
The patent implements nested doll by placing intermediate layers within the core and cover structure, with the dimple pattern formed on the outer surface. This nested arrangement allows complex multi-layered construction to be achieved through sequential manufacturing steps.
