Golf Club Head Face Member Segmentation for Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing golf club heads, as described in Patent Document 1, face challenges in face resilience due to the bending of the outer peripheral portion of the face member during ball impact, and there is a need to improve face resilience while maintaining joint strength between the face member and the head main body.
Innovation Solution
A golf club head design featuring a face member with a front plate portion, a backwardly directed first portion extending rearward from the front plate portion, and a centrally directed second portion extending toward the face center. The face member is fixed to the head main body via a face support portion, allowing the front plate portion to bend easily upon ball impact, thereby enhancing face resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the outer peripheral portion of the face member is made thick to maintain joint strength, then the joint strength between the face member and head main body is improved, but the face resilience deteriorates due to hindered bending
Solution Approach 1:
The face member is divided into multiple portions with different thickness characteristics: the outer peripheral portion has larger thickness for joint strength, while the central portion has smaller thickness for bending flexibility. This segmentation allows each region to optimize its function independently.
Solution Approach 2:
Different regions of the face member are assigned different thickness properties to meet local requirements. The outer peripheral portion uses larger thickness for structural support and joint strength, while the central portion uses smaller thickness to allow bending and improve face resilience during ball impact.
2Stability of the object's composition
If the face member is made rigid to maintain structural integrity, then the joint strength is improved, but the face resilience deteriorates due to reduced bending capability
Solution Approach 1:
The face member is segmented into regions with different rigidity characteristics. The outer peripheral portion maintains larger thickness for structural integrity, while the central portion reduces thickness to enable bending, creating a balance between stability and resilience.
Solution Approach 2:
The face member exhibits local quality variations where the outer peripheral portion is more rigid for structural support, while the central portion is more flexible for bending during impact, allowing simultaneous achievement of structural integrity and face resilience.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively improves face resilience by allowing the front plate portion to bend during ball impact, while maintaining the joint strength between the face member and the head main body, thus enhancing the overall performance of the golf club head.
Implementation Method 1
the bending of the outer peripheral portion of the face member at the time of hitting the ball is hindered, and there is room for further improvement in the face resilience

AI summary
A golf club head comprises a head main body and a face member. The head main body is provided with a face support portion to which the face member is fixed. The face member comprises a front plate portion, a backwardly directed portion extending backwardly of the head from the front plate portion, and a centrally directed portion extending toward of a center of the face from the backwardly directed portion. The rear surface of the centrally directed portion is fixed to the face support portion of the head main body.
