Golf Club Shaft Plug Sealing Epoxy Lumen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the manufacture of golf clubs, excess epoxy can flow into the shaft lumen, requiring removal, which is inefficient and may compromise the secure attachment of the club shaft to the club head.
Innovation Solution
A shaft plug is designed to seal off the shaft lumen by inserting a sealing member and internal members that deform or have cut-aways/slit configurations to create a fluid-tight barrier, preventing epoxy from entering the lumen during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If epoxy is applied to secure the club shaft to the club head, then attachment strength is improved, but excess epoxy flows into the shaft lumen requiring removal
Solution Approach 1:
A shaft plug is inserted into the shaft lumen before epoxy application to prevent excess epoxy from entering the lumen during the attachment process. This preliminary protective action eliminates the need for post-application cleanup and ensures clean epoxy distribution in the hosel gap.
2Strength
If epoxy is applied to secure the club shaft to the club head, then attachment strength is improved, but excess epoxy requires removal which compromises secure attachment
Solution Approach 1:
The shaft plug is installed beforehand to create a barrier that prevents epoxy contamination of the shaft lumen. This ensures that the epoxy remains concentrated in the hosel gap where it is needed for secure attachment, improving both the strength and reliability of the bond without requiring removal operations.
