Golf Club Head Structural Tension Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads do not effectively increase ball speed by reducing stress in the striking face section while minimizing mass addition.
Innovation Solution
An adjustable, stress-reducing cable system connects the crown and sole sections of the golf club head, using non-metal materials like aramid or liquid crystal polymer, looped through openings to form a woven structure near the striking face, with adjustable tension to optimize stiffness without compressing the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If interior structures like braces or sound components are added to the golf club head, then structural support and sound quality are improved, but the mass of the club head increases
Solution Approach 1:
The patent uses thin cable elements (flexible structural members) instead of traditional bulky braces or sound components. These cables are looped through openings in the striking face plate and anchored to the club head body, providing structural support and stress reduction with minimal mass addition. The cables act as tension members that reinforce the striking face without requiring heavy interior structures.
2Speed
If the striking face is stiffened to reduce deflection during impact, then ball speed is improved, but stress in the striking face increases
Solution Approach 1:
The cable system applies preliminary tension to the striking face plate before impact occurs. The cables are anchored to prevent excessive deflection during impact, thereby reducing stress concentrations. This preliminary reinforcement allows the face to maintain optimal stiffness for ball speed while distributing impact stresses more evenly across the structure.
Solution Approach 2:
The patent changes the structural parameters of the club head by introducing tension members (cables) that modify the stress distribution in the striking face. The cables create a pre-tensioned structure that alters how forces are transmitted during impact, reducing peak stresses while maintaining the face stiffness needed for high ball speed.
3Stress or pressure
If interior structures are added to reduce stress in the striking face, then stress reduction is achieved, but the complexity of the club head structure increases
Solution Approach 1:
The stress reduction function is segmented into discrete cable elements rather than using a monolithic interior structure. Multiple cables are distributed throughout the club head interior, each providing localized stress reduction where needed. This segmented approach reduces overall complexity compared to a single complex interior brace or sound component while achieving comprehensive stress management.
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 solution enhances ball speed by reducing stress on the striking face during impact without increasing the club head's mass, allowing for adjustable stiffness to optimize performance.
Implementation Method 1
The cable, which is placed in tension between the return or crown section and sole section
Implementation Method 2
adjusting the location of the set screw within the threaded screw bore changes the tension of the elongated cable within the body and a stiffness of the striking face
Data Source
AI summary
The disclosure is directed to a golf club head having an adjustable tension cable disposed proximate the face. The body has a face, a sole, and a return section, and defines a hollow interior. The cable extends between the return section and the sole within the hollow interior near the face to reduce stresses placed on the face during impact with a golf ball. The cable preferably forms a woven structure, with multiple connections between the return section and sole, and the tension in the cable is adjustable via a screw connected to one end of the cable that engages a threaded bore disposed near the hosel.
