Golf Club Head Face Segmentation for Rebound Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club heads face limitations in achieving high rebound performance, particularly at the peripheral edge part of the face, where the existing designs do not effectively distribute the CT value and deformation to enhance ball collision outcomes.
Innovation Solution
The design incorporates a connecting part that separates the face back surface from the head body, creating a clearance between the peripheral edge and the head body, allowing for increased deformation and improved rebound performance by distributing the CT value more effectively across the face surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the face part is connected directly to the head body, then the structural strength is improved, but the rebound performance at the peripheral edge part deteriorates
Solution Approach 1:
The face part is segmented from the head body through the introducing of a groove between them. This segmentation allows the face part to deform independently during ball impact, particularly at the peripheral edge regions, thereby improving rebound performance while maintaining structural integrity through the controlled separation.
Solution Approach 2:
The groove is strategically positioned to create different connection characteristics at different locations. The peripheral edge parts are separated from the head body to maximize rebound performance in these regions, while the central region maintains connection for structural support. This local differentiation optimizes both rebound performance and structural strength.
2Reliability
If the peripheral edge part of the face is separated from the head body, then the rebound performance is improved, but the structural stability deteriorates
Solution Approach 1:
The groove creates a controlled segmentation that separates the peripheral edge regions from the head body while maintaining the overall structural integrity. This allows the peripheral regions to achieve high rebound performance through independent deformation while the connected central structure maintains stability.
Solution Approach 2:
The depth and positioning of the groove are carefully controlled to achieve the desired balance. By adjusting the groove parameters (depth, width, position), the design optimizes the degree of separation to maximize rebound performance while maintaining sufficient structural stability for practical use.

AI summary
A head 2 includes a head body h1, a face part Fp1, and a connecting part Cn1. The face part Fp1 includes a face surface f1 and a face back surface f2. The connecting part Cn1 connects the face back surface f2 of the face part Fp1 and the head body h1 to each other. The connecting part Cn1 may be provided at a position separated from a peripheral edge of the face back surface f2. The peripheral edge of the face back surface f2 may be separated from the head body h1. The face part Fp1 may include a face middle region R1 and a face peripheral region R2. The connecting part Cn1 may be provided only in the face middle region R1.
