Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a high gloss coating is applied to the golf ball, then the aesthetic appearance is improved, but external light reflection increases causing golfer distraction

Engineering Contradiction:
Improvesurface glossVSAvoidexternal light reflection
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent applies a matte or satin finish coating that changes the surface optical properties from high reflectance (glossy) to low reflectance (matte/satin). This reduces external light reflection toward the golfer's eyes while maintaining the ball's visual appearance, directly resolving the contradiction between aesthetic appearance and light reflection distraction.

2Object-affected harmful factors

If inorganic particles are added to the coating composition, then surface gloss is reduced, but impact resistance and cutting resistance decrease

Engineering Contradiction:
Improvesurface glossVSAvoidimpact resistance and cutting resistance
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent uses a composite coating formulation combining organic resin components with carefully selected inorganic particles. The organic matrix provides flexibility and impact resistance, while the inorganic particles provide matting effect. This composite structure resolves the contradiction by allowing both gloss reduction and maintenance of mechanical properties through synergistic material combination.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent controls the particle size, shape, and concentration of inorganic particles to optimize the balance between matting effect and mechanical performance. By adjusting these parameters, the coating achieves sufficient gloss reduction while maintaining impact and cutting resistance through optimized particle characteristics rather than simply adding more inorganic content.

Inventive Principle:
Principle #35Parameter changes

3Strength

If the coating is made more flexible to reduce surface damage, then impact resistance improves, but the coating may become too soft affecting durability

Engineering Contradiction:
Improveimpact resistanceVSAvoidcoating durability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent adjusts the polymer chain flexibility, crosslink density, and molecular weight of the organic resin to achieve optimal balance between flexibility and durability. By controlling these parameters, the coating becomes flexible enough to absorb impact energy while maintaining sufficient strength and adhesion for long-term durability, resolving the contradiction between impact resistance and coating reliability.

Inventive Principle:
Principle #35Parameter changes
