VSEngineering Contradiction Analysis

1Stability of the object's composition

If dimple patterns are based on geometric shapes like Platonic Solids and Archimedean Solids to achieve aerodynamic symmetry, then aerodynamic symmetry is improved, but the number of available patterns is limited and surface coverage is suboptimal

Engineering Contradiction:

Improveaerodynamic symmetryVSAvoidnumber of available patterns

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The invention divides the spherical surface into multiple zones (equatorial zone, polar zones) and further segments each zone into multiple dimple rows with different spacing patterns. This segmentation allows for numerous unique pattern variations while maintaining aerodynamic symmetry, directly resolving the contradiction between symmetry and pattern diversity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention applies different dimple row spacing patterns to different zones of the golf ball surface. The equatorial zone has one spacing pattern while polar zones have different spacing patterns, creating locally optimized dimple arrangements that maximize surface coverage and aerodynamic performance without requiring complete pattern redesign.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If dimple patterns are based on geometric shapes to achieve aerodynamic symmetry, then aerodynamic symmetry is improved, but surface coverage is less than optimal

Engineering Contradiction:

Improveaerodynamic symmetryVSAvoidsurface coverage

Core Design Contradiction:

Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The invention creates a dynamic dimple pattern system where rows of dimples are spaced at different intervals within different zones. This dynamic arrangement allows the dimple pattern to adapt to the spherical geometry more effectively, maximizing surface coverage while maintaining aerodynamic symmetry through the coordinated spacing variations.
