Golf Club Head Truss Vibration Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club designs have altered vibration and deflection characteristics due to mass manipulations, leading to suboptimal feel, directional control, and energy transfer during impact, with limited structural tuning to counteract these effects.
Innovation Solution
Incorporating truss members across the rear cavity of the golf club head to mechanically couple the sole and top line, reducing vibration displacement and tuning frequencies to improve energy transfer and overall performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-material constructions and mass manipulations are used to precisely locate the center of gravity, then forgiveness and energy transfer are improved, but vibration and deflection characteristics are altered detrimentally
Solution Approach 1:
The patent changes the structural parameters of the club head by incorporating a truss structure with specific geometry, member thickness, and material properties. This allows tuning of the vibration modes and deflection characteristics to compensate for the effects of mass manipulations, thereby maintaining reliable center of gravity location while correcting harmful vibration effects.
Solution Approach 2:
The patent employs composite construction by combining the truss structure (made of one material) with the club head body (made of different materials including multi-density materials). This composite approach allows independent optimization of vibration characteristics through the truss while maintaining the mass distribution benefits of the multi-material body.
2Adaptability or versatility
If cavity back construction is used to concentrate mass at the periphery, then forgiveness is improved, but structural integrity and vibration control are compromised
Solution Approach 1:
The patent segments the club head structure by adding a truss framework that divides the cavity space. This segmentation provides internal structural support that maintains integrity while preserving the perimeter weight concentration for forgiveness. The truss members act as internal scaffolding that reinforces the cavity back construction.
Solution Approach 2:
The patent adds a three-dimensional truss structure within the two-dimensional plane of the club head face. This dimensional addition provides structural reinforcement throughout the volume of the cavity, improving overall structural integrity without altering the perimeter mass distribution that provides forgiveness.
3Object-affected harmful factors
If viscoelastic back plate materials are used to dampen vibration, then vibration control is partially improved, but structural tuning capability is limited
Solution Approach 1:
The patent introduces the truss structure as an intermediary element between the club head body and the environment. This truss mediator actively tunes vibration modes through its structural properties, providing more comprehensive vibration control than passive viscoelastic materials alone while maintaining design flexibility.
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 truss structure enhances sound, feel, and distance control by efficiently transferring energy to the golf ball, improving the club's structural integrity and forgiveness.
Implementation Method 1
The at least one truss member extends across at least a portion of the rear cavity and mechanically couples the sole and an area of the top line exhibiting maximum displacement of a vibration mode in a frequency less than 5500 Hz

AI summary
A golf club includes a golf club head that is generally constructed as a perimeter weighted golf club head and comprises a perimeter body, a hosel, at least one truss member and a face. The truss member extends between portions of the perimeter body to tune the vibration and deflection response of the golf club head in response to a golf ball impact.
