Golf Club Head Face Plate Segmented Support Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club heads lack an effective structure for attaching a face plate that enhances rebound performance and flight consistency, particularly in deviating hit points.
Innovation Solution
A golf club head design featuring a face plate with a circular outer peripheral edge divided into first and second portions, where the second portion does not abut the receiving surface, forming a gap, and an elastic body or plastic deforming part is used to promote deflection and improve rebound performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the face plate is fully supported by the receiving surface, then the structural stability and durability are improved, but the rebound performance and flight consistency deteriorate due to restricted deflection
Solution Approach 1:
The outer peripheral edge part is segmented into a first portion that abuts the receiving surface and a second portion that does not abut, creating a gap. This segmentation allows different regions of the face plate to have different support conditions, enabling both stability and deflection capability
Solution Approach 2:
Different portions of the face plate are given different local properties: the first portion has full support for stability, while the second portion has reduced support (gap formation) to enable deflection. This local differentiation resolves the contradiction between overall stability and localized rebound performance
2Power
If the face plate is made thinner to reduce weight, then the rebound performance is improved, but the strength and durability worsen
Solution Approach 1:
The face plate is designed as a thin-walled structure that can flexibly deform during impact. The thin design enables better rebound performance while the strategic support arrangement (first portion abutting, second portion with gap) provides necessary structural integrity
Solution Approach 2:
The face plate transitions from a static, fully-supported structure to a dynamic structure that can deflect. The gap under the second portion allows the face plate to dynamically deform during ball impact, improving rebound while maintaining durability through controlled flexibility
3Strength
If the face plate is made thicker to increase strength, then the durability is improved, but the rebound performance and flight consistency deteriorate due to reduced deflection capability
Solution Approach 1:
By segmenting the support structure into first and second portions with different support characteristics, the invention enables thick face plates to maintain both strength and deflection capability. The gap region allows necessary flexibility even in thicker designs
Solution Approach 2:
The support condition is locally differentiated: full support in the first portion for strength, and reduced support (gap) in the second portion for deflection. This allows the face plate to have overall thickness for durability while maintaining local flexibility for rebound performance

AI summary
A head 2 includes a head body h1 and a face plate p1 fixed to the head body h1. The face plate p1 includes a plate front surface f1 having a hitting face, a plate back surface b1 which is a surface opposite to the plate front surface f1, and a plate side surface s1. The head body h1 includes an opening part to which the face plate is disposed, and a receiving surface u1 which supports the face plate p1 from back. The plate back surface b1 includes an outer peripheral edge part 16 having a circular shape. The outer peripheral edge part 16 includes a first portion x1 which abuts on the receiving surface u1, and a second portion which does not abut on the receiving surface u1 and forms a gap gp between the second portion and the receiving surface u1.
