Golf Club Head Weight Insert Structure for Lower Center of Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads lack the ability to effectively adjust the position of the center of gravity and weight distribution, limiting performance enhancements.
Innovation Solution
A golf club head design featuring a weight member that is inserted into a receiving portion and fixed with a joint portion, supported by lower, toe-side, heel-side, and upper support portions, allowing for the center of gravity to be lowered and weight distribution adjusted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a weight member is inserted into a body recess to adjust center of gravity position, then the center of gravity position can be adjusted, but the structural complexity increases
Solution Approach 1:
The weight member receiving portion is divided into multiple support portions (lower support portion, toe-side support portion, heel-side support portion, upper support portion) that independently support different sides of the weight member. This segmentation allows for precise control of the weight member's position and orientation while maintaining a relatively simple overall structure.
Solution Approach 2:
The weight member receiving portion acts as an intermediary structure between the head body and the weight member. It provides a standardized interface that simplifies the assembly process and allows for easy adjustment of the weight member's position without complicating the overall club head structure.
2Stability of the object's composition
If multiple support portions are provided for the weight member, then the weight distribution and balance are improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple support portions are merged into a single integrated weight member receiving portion structure. This combining approach allows the club head to be manufactured as a unified component, reducing the number of separate parts and simplifying the assembly process while maintaining the multi-point support functionality for optimal weight distribution.
Solution Approach 2:
The weight member receiving portion serves multiple functions simultaneously: it supports the weight member, distributes weight, maintains balance, and provides structural integrity. This multi-functionality reduces the need for additional separate components, thereby simplifying manufacturing while achieving stable weight distribution.
3Strength
If the weight member is fixed with a joint portion, then the connection strength is improved, but the device complexity increases
Solution Approach 1:
The joint portion is strategically positioned at specific locations where the weight member interfaces with the head body. By concentrating the joint structure at these critical points rather than uniformly across the entire interface, the design achieves strong connections while minimizing overall structural complexity.
Solution Approach 2:
Instead of adding complex joint structures to achieve strong connections, the design inverts the approach by using the weight member receiving portion's geometric features and material properties to provide inherent strength. The joint portion is designed to be simple and integrated, relying on the overall structure rather than complex fastening mechanisms.

AI summary
A golf club head includes a striking face. The head further includes: a head body having a face opening and a weight member receiving portion; a face member covering the face opening and forming at least a part of the striking face; a weight member inserted into the weight member receiving portion from a face side and fixed thereto; and a joint portion formed on a boundary between the weight member receiving portion and the weight member. The weight member receiving portion includes: a lower support portion supporting a lower side of the weight member; a toe-side support portion supporting a toe side of the weight member; a heel-side support portion supporting a heel side of the weight member; an upper support portion supporting an upper side of the weight member; and an upward opening formed by an absence of a portion of material in the upper support portion.
