Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a conventional dimple pattern is used, then the golf ball can be manufactured with simple cover formation techniques, but the golf ball assembly becomes unstable and asymmetric during complex cover formation processes

Engineering Contradiction:

Improvegolf ball assembly stabilityVSAvoiddimple pattern complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The golf ball surface is segmented into multiple zones (first zone, second zone, third zone, fourth zone) with distinct dimple configurations. Each zone contains specific numbers and arrangements of dimples, allowing different regions to serve different functional purposes during cover formation while maintaining overall assembly stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The dimple pattern incorporates asymmetric arrangements where certain zones have different dimple densities and configurations. The first and second zones differ from the third and fourth zones, with specific zones containing 3-6 dimples while others contain 7-10 dimples, creating controlled asymmetry that stabilizes the assembly during complex formation processes.

Inventive Principle:

Principle #4Asymmetry

2Ease of manufacture

If the dimple pattern is simplified, then the manufacturing process becomes easier, but aerodynamic performance deteriorates

Engineering Contradiction:

Improvecover formation easeVSAvoidaerodynamic performance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

Different zones of the golf ball surface have different dimple configurations optimized for local requirements. The first and second zones have different dimple arrangements than the third and fourth zones, with each zone's dimple pattern tailored to provide appropriate aerodynamic characteristics while facilitating the specific manufacturing techniques used for that region.

Inventive Principle:

Principle #3Local quality

3Reliability

If a complex dimple pattern is used, then aerodynamic performance is improved, but the manufacturing process becomes more difficult and less stable

Engineering Contradiction:

Improveaerodynamic performanceVSAvoidcover formation difficulty

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

By dividing the golf ball surface into distinct zones with specific dimple configurations, the complex pattern becomes manageable during manufacturing. Each zone can be formed with controlled precision, allowing complex overall patterns to be achieved through systematic regional construction rather than attempting uniform complexity throughout.

Inventive Principle:

Principle #1Segmentation
