Golf Club Head Connecting Portion for Face Member Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club head structures with an elastic member interposed between the head body and face member have inferior durability and ball striking performance compared to directly joined structures.
Innovation Solution
A hollow golf club head design featuring a connecting portion between the head body and face member, with a first concave portion on the head body and a second concave portion on the face member, allowing the face member to be floatingly supported and slightly displaced, using materials like titanium alloys for the head and face members and lower rigidity materials like rubber or resin for the connecting portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elastic member is interposed between the head body and face member, then ball striking performance is improved through displacement, but durability of the connection is reduced
Solution Approach 1:
A connecting portion is introduced as an intermediary element between the head body and face member. This connecting portion includes a first concave portion on the head body and a second concave portion on the face member, creating a controlled interface that allows limited displacement while maintaining strong mechanical connection through the interlocking concave structures, thus resolving the contradiction between performance improvement and connection durability
Solution Approach 2:
The rigidities of the connecting portion are adjusted by changing material properties and structural parameters. The connecting portion is designed with specific rigidity characteristics that allow it to be flexible enough for displacement during impact yet rigid enough to maintain durable connection, optimizing both ball striking performance and connection reliability through parameter control
2Reliability
If the face member is directly joined to the head body, then durability of connection is improved, but ball striking performance is reduced due to lack of displacement capability
Solution Approach 1:
The direct joined structure is segmented into three distinct components: the head body, the connecting portion with concave portions, and the face member. This segmentation allows the connecting portion to serve as a specialized interface element that provides both mechanical connection and controlled displacement capability, overcoming the limitations of direct joining while maintaining connection durability
3Reliability
If a connecting portion with concave portions is used, then durability is improved through better connection, but device complexity increases
Solution Approach 1:
The connecting portion merges multiple functions into a single integrated component: it provides mechanical connection between head body and face member, enables controlled displacement through its concave portion design, and ensures durability through the interlocking structure. This merging approach achieves improved reliability without proportionally increasing overall device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves ball striking performance by reducing spin and enhancing carry, while increasing the durability of the connection between the head body and face member through adjustable displacement and reduced collision risk, maintaining conventional face portion alignment with the shaft.

AI summary
A hollow golf club head includes a face portion. The head includes a hollow head body, a face member that forms the face portion, and a connecting portion provided between the head body and the face member connects the head body and the face member. The head body includes a front surface to which the face member is connected through the connecting portion. The front surface of the head body includes an opening portion and a first concave portion formed around the opening portion and on which the connecting portion is arranged. The back surface of the face member includes a second concave portion on which the connecting portion is arranged.
