Golf Club Head Cavity Insert Retention via Segmented Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club head inserts within cavities can become dislodged during impact, leading to undesirable vibrations and a compromised gaming experience.
Innovation Solution
A golf club head design featuring a central tuning port weight (CTP) insert that is mechanically secured within the cavity using a combination of surface friction, press fits, and adhesive, with components such as first and second components creating a retention lock or interlock to prevent dislodging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an insert is placed within the cavity to reduce vibrations, then vibration reduction is improved, but the insert becomes dislodged during impact
Solution Approach 1:
The insert is divided into multiple segments or components that can independently engage with corresponding features in the cavity. This segmentation allows each component to perform a specific retention function while collectively providing secure anchoring and vibration reduction.
Solution Approach 2:
The insert components are nested within the cavity such that each component fits into a corresponding recess or feature. This nesting arrangement ensures that the insert remains securely positioned within the cavity while maintaining the desired vibration damping properties.
2Ease of operation
If the strikeface is made thinner to improve ball contact, then ball contact is improved, but structural support is compromised
Solution Approach 1:
The golf club head incorporates composite materials with varying mechanical properties in different regions. The strikeface uses materials optimized for ball contact and energy transfer, while the cavity and insert structures use materials providing structural support and vibration damping, creating a composite construction that achieves both thin strikeface and adequate support.
Solution Approach 2:
Different regions of the golf club head are designed with locally optimized properties. The strikeface area is designed for optimal ball contact with appropriate thickness and material properties, while the cavity regions incorporate inserts with specific mechanical characteristics to provide localized support and vibration control without compromising the thin strikeface design.
