Angled Golf Club Back Weight Assembly for Impact Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads with movable weight channels suffer from stress concentrations and oscillations due to heavy weight assemblies, leading to potential failure and reduced durability, while maintaining desirable center of gravity and moment of inertia is challenging.
Innovation Solution
The golf club head incorporates an angled weight assembly with a weight channel oriented at an angle relative to the ground plane, reducing oscillations and eliminating the need for support structures, allowing for redistribution of discretionary mass to improve CG and MOI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If heavy weight assemblies are used in traditional weight channels, then center of gravity and moment of inertia can be adjusted, but stress concentrations and oscillations occur leading to potential failure
Solution Approach 1:
The weight channel is reoriented at an angle (e.g., 45 degrees) relative to the club head's longitudinal axis, transitioning from a conventional straight-channel configuration to an angled configuration. This dimensional change in channel orientation redistributes stress during impact, reducing stress concentrations and oscillations while maintaining the ability to adjust center of gravity and moment of inertia through weight repositioning
Solution Approach 2:
The patent changes the geometric parameter of the weight channel from a conventional straight alignment to an angled configuration. This parameter change (angle of the weight channel) fundamentally alters the stress distribution characteristics during club impact, reducing harmful oscillations while preserving weight adjustment functionality
2Stability of the object's composition
If support structures are added to stabilize weight channels, then oscillations are reduced, but device complexity and structural interference increase
Solution Approach 1:
The patent eliminates the need for additional support structures by extracting the stabilization function from separate structural elements and embedding it into the fundamental geometry of the weight channel itself. The angled configuration of the weight channel inherently provides stability during impact without requiring ribs, braces, or other support features, thereby reducing device complexity
3Reliability
If weight channels are made shorter to reduce stress, then durability improves, but center of gravity adjustment range is limited
Solution Approach 1:
By angling the weight channel relative to the club head's longitudinal axis, the patent effectively increases the usable length of the weight channel within the same physical space. This angular orientation allows the weight to traverse a longer path while maintaining a compact channel structure, thereby extending the center of gravity adjustment range without requiring a longer channel that would increase stress

AI summary
A wood-type golf club head includes an angled weight assembly with an adjustable weight disposed within a weight channel. The adjustable weight assembly is positioned at an angle relative to a ground plane to reduce and redirect bending of the golf club head at impact. The reduction and redirection of bending decreases and redirects stress applied to the weight channel at impact to reduce resultant oscillations of the weight channel, which in turn reduces support material for the weight assembly and increases discretionary mass.
