Golf Club Head Cavity Insert Retention Mechanism
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 a first and second component creating a retention lock or interlock, and protrusions and grooves to prevent dislodging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an insert is placed within a cavity of a golf club head, then vibrations are reduced and feel/sound are enhanced, but the insert becomes dislodged during impact
Solution Approach 1:
The insert is divided into multiple components (first component and second component) that can be separately assembled. The first component is secured to the cavity wall while the second component forms the vibration-dampening core, allowing each part to fulfill its specific function while working together as a unified retention system.
Solution Approach 2:
The second component is nested within the first component, creating a layered structure where the vibration-dampening material is contained within the retention structure. This nested arrangement maximizes space utilization within the cavity while ensuring both retention and vibration reduction functions are achieved.
2Reliability
If a mechanical securement system is implemented, then insert retention is improved, but device complexity increases
Solution Approach 1:
The insert structure utilizes the cavity wall itself as part of the retention mechanism. The first component is directly secured to the cavity wall, eliminating the need for separate retention structures or additional fastening systems. The system serves itself by integrating the retention function into the existing cavity geometry.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The secure insertion of the CTP weight reduces vibrations, enhances the feel and sound of the golf club, and allows for a thinner strikeface while maintaining support, thereby improving the overall gaming experience.
Implementation Method 1
The CTP weight can be secured to the club head using any suitable method, such as adhesive, mechanical interlock, press fit, friction fit, or combinations thereof.
Implementation Method 2
The CTP weight can be secured to the club head using any suitable method, such as adhesive, mechanical interlock, press fit, friction fit, or combinations thereof.
