Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads exhibit instability in spin performance during off-center impacts, leading to inconsistent ball flight and reduced average distance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single surface texturing is applied to the striking face, then the manufacturing process is simple, but the spin performance stability during off-center impacts is poor
Solution Approach 1:
The striking face is divided into multiple regions (central region, toe region, heel region) with different surface texturing patterns. The central region has a first surface texturing while the toe and heel regions have a second surface texturing, creating distinct functional zones that optimize spin performance across different impact locations.
Solution Approach 2:
Different surface texturing characteristics are applied to different regions of the striking face. The central region receives a first surface texturing with specific properties, while the toe and heel regions receive a second surface texturing with different properties, allowing each region to be optimized for its specific function.
2Reliability
If the toe and heel regions have additional texturing and overlapping surfaces, then the spin stability during off-center impacts is improved, but the manufacturing complexity increases
Solution Approach 1:
The first surface texturing is applied to the entire striking face including the central, toe, and heel regions as a preliminary step. Then, the second surface texturing is applied specifically to the toe and heel regions, creating overlapping processed surfaces that enhance spin stability while following a systematic manufacturing sequence.
Solution Approach 2:
The patent introduces a dimensional aspect to the surface texturing by creating overlapping processed surfaces through multiple texturing passes. This multi-layer approach adds complexity in the surface structure dimension, providing enhanced spin stability through the cumulative effect of multiple texturing layers.
3Manufacturing precision
If multiple surface texturing layers are applied to enhance spin performance, then the spin control is improved, but the manufacturing time and process complexity increase
Solution Approach 1:
The manufacturing process employs periodic action by applying surface texturing in distinct stages: first, the central region is textured, then the toe and heel regions are textured with overlapping processing. This periodic application of texturing ensures precise spin performance while organizing the manufacturing process into manageable cycles.

AI summary
A golf club head includes a face portion that includes a striking face, a sole portion, and a hosel portion. The striking face is divided into a central region, a toe region located on a toe side of the central region, and a heel region located on a heel side of the central region. The central region includes first processed surfaces formed by a first surface texturing. The toe region and the heel region each include the first processed surfaces formed by the first surface texturing, second processed surfaces formed by a second surface texturing, and overlapping processed surfaces formed by the first surface texturing and the second surface texturing overlapping each other. The first processed surfaces are covered by a coating layer.
