Golf Club Head Weight Distribution via Nested Cover Void
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club designers face challenges in achieving optimal weight distribution and aesthetics, as existing designs often compromise on weight reduction and performance characteristics, leading to undesirable sound and trajectory issues during ball strikes.
Innovation Solution
The introduction of a golf club head with a geometric weighting feature, such as a void formed in the rear, which is covered to maintain a traditional appearance, allowing for reduced weight and adjustable weight redistribution to enhance performance characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If weight is reduced from the club head, then performance characteristics improve, but the club head appearance becomes non-traditional and aesthetics deteriorate
Solution Approach 1:
A cover member is positioned within a recess formed in the club head, creating a nested structure where the cover fits inside the recess. This allows the club head to have an internal void for weight reduction while the cover restores the traditional external appearance, resolving the contradiction between weight reduction and aesthetic appearance.
2Weight of moving object
If weight is redistributed in the club head, then center of gravity adjusts and ball flight improves, but the structural complexity increases
Solution Approach 1:
The club head is divided into multiple segments including a body, a recess, and a cover member. This segmentation allows independent optimization of each component - the body can contain weight redistributing features while the cover restores appearance, managing structural complexity through modular design.
Solution Approach 2:
The nested structure of the cover within the recess allows the club head to incorporate weight redistribution features internally while maintaining a simple external appearance, managing complexity by hiding complex internal structures within the nested configuration.
3Weight of moving object
If a void is created in the club head for weight reduction, then performance improves, but unwanted sound is generated during ball strikes
Solution Approach 1:
The cover member nested within the recess acts as a sound-dampening element that fills the internal void space. This nested structure allows the club head to benefit from the weight reduction of the void while the cover material absorbs impact sounds, resolving the contradiction between weight reduction and unwanted sound generation.

AI summary
A golf club head has a body defining a ball striking face. The body further has a rear portion comprising a plurality of side walls and a planar lower portion. The plurality of side walls extend downward from a top of the golf club head towards the planar lower portion. The body further comprises a cover extending over the rear. The body further defines a gap between the cover and the planar portion.
