Golf Club Head Junction Using Complementary Ledge Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head technologies lack advancements in design and manufacturing, particularly in the junction formation between sections, which can affect the distribution of force and strength during impact.
Innovation Solution
The design incorporates complementary ledge members with specific vertical and horizontal sides to form a strong junction area, allowing for separate sections of the golf club head to engage and distribute force effectively, using materials like metals and composites for optimized performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a two-piece golf club head is joined by a brazed joint, then the club head can be manufactured with separate body and face portions, but the junction strength and force distribution are insufficient
Solution Approach 1:
The golf club head is divided into multiple separate sections (body, face, crown, sole) that are manufactured independently and then joined together through engagement features, allowing each section to be optimized separately while maintaining overall structural integrity
Solution Approach 2:
The junction area is designed with ledge members that extend in multiple dimensions (vertical sides, horizontal sides, depth), creating a three-dimensional engagement structure that distributes forces across a larger volume rather than a simple two-dimensional brazed joint
2Ease of manufacture
If ledge members are used to engage sections, then the junction area is formed, but without a third vertical side the engagement is insufficient
Solution Approach 1:
Each section is designed with complementary ledge members that have multiple sides (first vertical side, second vertical side, third vertical side, horizontal sides) that segment the engagement interface into multiple contact surfaces, increasing the reliability of the connection
Solution Approach 2:
Different sections may be manufactured from different materials (metal, composite) and the ledge member design accommodates these material differences by providing a mechanical engagement structure that ensures reliable connection regardless of material properties
3Strength
If sections are engaged to form the club head, then force can be distributed over a larger area, but the device complexity increases
Solution Approach 1:
Multiple sections with complementary ledge members are merged through engagement to form the complete club head, combining the benefits of separate manufacturing with the strength of an integrated structure
Solution Approach 2:
The ledge members are designed to self-align and self-engage during assembly, with the first vertical side matching with the first vertical side of the complementary ledge member, reducing the need for complex alignment procedures or additional fastening mechanisms

AI summary
Golf club heads including first section (113, 117) and a second section (115, 119) that are separate and distinct from one another and are engaged to form at least a portion of the golf club head. The first section may include a first ledge member (113a) and the second section may include a second ledge member (115a) and the first ledge member may be engaged with the second ledge member to form a junction area. The first ledge member includes a first vertical side (113b) and a second vertical side (113d) and a horizontal side (113c) therebetween and the second ledge member may include a first vertical side (115b) and a second vertical side (115d) and a horizontal side (115c) therebetween. The first and second ledge members are complementary. Golf clubs including these club heads and methods of making a golf club and golf club heads also are provided.
