Golf Club Head Weight Layout for Lower Sweet Spot Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club heads with internal hollow portions, such as fairway woods and hybrids, face limitations in design freedom due to the need to combine unique metallic main body and face components to create a lip-shaped protrusion, restricting the shaping of the sweet spot and internal weight placement.
Innovation Solution
A golf club head design featuring a hollow main body with an internal weight member positioned within a pedestal portion on the sole, accessible from the outside for easy fixation, allowing for various shapes and positions without contacting the face or thin-wall portion, enhancing design freedom and maintaining rebound performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the metallic main body and metallic face component are combined to create a lip-shaped protrusion, then the structural integrity is improved, but the degree of freedom in designing shapes is reduced
Solution Approach 1:
The golf club head is divided into a head main body and a separate internal weight member. The internal weight member is positioned within the hollow portion and fixed to the pedestal portion, allowing independent design and optimization of each component's shape without being constrained by the need to form a unified lip-shaped protrusion through combination of multiple metallic parts.
2Length of moving object
If the internal weight member is positioned to lower the sweet spot height, then the flight distance is improved, but the design flexibility is reduced
Solution Approach 1:
The internal weight member is positioned in the vertical dimension within the hollow portion, extending toward the face at a position above the thin-walled portion. This vertical positioning allows the sweet spot height to be lowered for improved flight distance while maintaining horizontal design flexibility for various head shapes and weight distributions.
3Strength
If the internal weight member contacts the face or thin-wall portion, then the structural support is improved, but the rebound performance is reduced
Solution Approach 1:
The internal weight member is positioned to extend toward the face at a location specifically above the thin-walled portion, creating a localized weight distribution that provides structural support through the pedestal portion connection without interfering with the face's elastic deformation during ball impact. This localized positioning maintains rebound performance while achieving the desired center of gravity location.

AI summary
A method for manufacturing a golf club head comprises: fixing an internal weight member to a sole of a first member from the outside through an opening; and fixing a second member to the first member to close the opening. The first member is provided, at a position accessible from the outside of the first member, with a pedestal portion protruding toward the crown. The first member comprises a thin-walled portion between the pedestal portion and the face. The pedestal portion comprises: a first part for positioning the internal weight member in the up-down direction, and a second part for positioning the internal weight member in the toe-heel direction and/or front-back direction of the head. The internal weight member positioned by the first and second parts, extends toward the face at a position above the thin-wall portion without contacting with the thin-wall portion and the face.
