Golf Club Head Miter Joint for Vacuum Brazing Thin Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for brazing dissimilar materials in golf club heads, such as titanium and steel, are costly, complex, and impractical for thin cross-sectional regions, leading to stress concentration and limited joint implementation, while traditional joints like tongue-and-groove require precise fitment and add unnecessary weight.
Innovation Solution
A miter joint using nickel-based or copper-based filler materials is employed in a vacuum brazing process to join dissimilar materials, such as titanium and steel, reducing complexity and cost, and allowing for a self-centering, durable joint in highly stressed regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tongue-and-groove joint is used for brazing face plate to club body, then joint strength is improved, but manufacturing complexity and cost increase due to precise fitment requirements and tight corners
Solution Approach 1:
The joint is divided into a male portion on the face plate and a female portion on the club body, with each portion having simplified geometry that eliminates tight corners while maintaining structural integrity through the brazing process
Solution Approach 2:
Instead of creating interlocking geometric features requiring precise fitment, the invention inverts the approach by using a simple male-female configuration where the brazing material itself provides the bonding strength, eliminating the need for complex mechanical interlocking
2Strength
If tongue-and-groove joint is used, then joint security is improved, but weight increases due to additional material required
Solution Approach 1:
The invention extracts the unnecessary geometric interlocking features from the joint design, retaining only the essential male-female configuration needed for alignment, while eliminating excess material that would increase weight without contributing to joint strength
3Reliability
If larger joint width is used for tongue-and-groove, then brazing success is improved, but heat management challenges increase in thin cross-sectional regions
Solution Approach 1:
The joint design adapts to local cross-sectional dimensions by using a male-female configuration that can be scaled to match the available material thickness at each location, allowing adequate brazing material placement without requiring excessive joint width that would cause heat management issues in thin sections
4Reliability
If tongue-and-groove joint with tight corners is used, then brazing security is improved, but stress concentration increases in highly stressed regions
Solution Approach 1:
The invention inverts the traditional approach of creating stress-resistant joints through geometric interlocking, instead using a simplified male-female configuration where the stress distribution is optimized by eliminating tight corners and allowing the brazing material to provide uniform bonding without stress concentration points
