Solution Overview

Problem

Existing golf balls lack durable and effective sighting aids that allow golfers to accurately align the ball with the intended direction of travel, violating the Rules of Golf and hindering performance improvement.

Innovation Solution

A golf ball with a sighting aid featuring a continuous or discontinuous series of characters, symbols, or a combination thereof, extending partially around the perimeter, determined by specific equations to provide alignment references, with surface coverage and wrap percentages optimized for visibility and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a continuous or discontinuous series of characters or symbols is used as a sighting aid, then alignment accuracy is improved, but the complexity of the design increases

Engineering Contradiction:
Improvealignment accuracyVSAvoidsighting aid design complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sighting aid is segmented into discrete characters or symbols arranged in a sequence around the ball's perimeter. This segmentation allows for durable, discrete alignment markers that can be individually positioned and maintained, resolving the contradiction by providing precise alignment references without requiring a continuous complex pattern.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sighting aid extends around the perimeter of the ball in a circumferential arrangement, utilizing the three-dimensional surface of the sphere. This dimensional approach allows multiple characters to be distributed around the ball, providing alignment references from various angles while maintaining a systematic, non-overlapping configuration that manages design complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Illumination intensity

If the sighting aid extends partially around the perimeter of the ball, then alignment visibility is improved, but the surface area occupied increases

Engineering Contradiction:
Improvealignment visibilityVSAvoidsurface area occupied
Core Design Contradiction:
Illumination intensityVSArea of stationary object

Solution Approach 1:

The sighting aid is positioned specifically at the perimeter of the ball, concentrating the alignment functionality in a localized circumferential zone. This local placement provides maximum visibility for alignment purposes while confining the occupied surface area to the equatorial region, leaving the rest of the ball surface available for other markings or aesthetics.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If handmade lines are used for alignment, then customization is improved, but durability deteriorates

Engineering Contradiction:
Improvealignment customizationVSAvoidmarking durability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The sighting aid consisting of characters or symbols is pre-applied to the ball during manufacturing, establishing durable alignment markings before the ball enters service. This preliminary application ensures the alignment aids are factory-sealed and protected, combining the customization of pre-designed character sequences with the durability of integrated manufacturing processes.

Inventive Principle:
Principle #10Preliminary action
