Golf Club Head Support Bracket for Center of Gravity Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cavity back golf club heads face limitations in controlling ball flight trajectory due to their high center of gravity and limited options for repositioning the center of gravity, which affects accuracy and distance, especially for off-center hits.
Innovation Solution
The design incorporates a thin striking face and perimeter weighting member with support brackets made of lightweight materials, allowing for discretionary weight placement to alter the weight distribution and reposition the center of gravity, enhancing trajectory control and forgiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If perimeter weighting is used in cavity back golf club heads, then the moment of inertia increases and resistance to twisting improves, but the center of gravity becomes relatively high which limits trajectory control
Solution Approach 1:
The club head is divided into functional zones: perimeter weighting members provide stability while support brackets create open spaces that allow strategic weight placement. This segmentation enables simultaneous optimization of both twisting resistance and trajectory control by separating the functions of structural support and weight distribution.
Solution Approach 2:
Different regions of the club head are assigned different weight densities. Lightweight materials are used in the striking face and support brackets to lower the center of gravity, while dense weighting members are positioned at the perimeter to maintain moment of inertia. This local differentiation of material properties resolves the contradiction between stability and trajectory control.
2Adaptability or versatility
If weight is repositioned away from the club head face and lower in the structure, then options for center of gravity positioning increase, but structural integrity may be compromised
Solution Approach 1:
Support brackets serve as intermediary structural elements that connect the striking face to the perimeter weighting members. These brackets provide the necessary structural integrity to allow weight repositioning, as they maintain the rigidity of the club head while enabling the separation of weight-bearing functions between the perimeter members and the support structure.
Solution Approach 2:
The club head employs composite construction with lightweight materials (such as titanium or aluminum alloys) for the striking face and support brackets, combined with dense weighting materials (such as tungsten or lead) at the perimeter. This composite approach allows strategic weight distribution that expands center of gravity positioning options while maintaining overall structural strength through the synergistic combination of materials with different density and strength properties.

AI summary
A cavity back golf club and golf club head having one or more support brackets is disclosed. Each support bracket includes a first portion engaged with the rear surface of the striking face, a second portion engaged with the perimeter weighting member, and a third portion that is curved. The one or more of the support brackets are engaged with a rear surface of a striking face and a perimeter weight member of the golf club head. The one or more support brackets are at least partially located in a rear cavity of the golf club head. The support brackets provide structural integrity to a thin striking face on the golf club head. Additionally, a discretionary weight is engaged with the at least one of the support brackets at the toe portion of the golf club head.
