Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club head designs lack the ability to adjust the center of gravity along multiple axes, limiting the optimization of weight distribution and performance characteristics such as loft, lie, and face angle.
Innovation Solution
A golf club head design featuring adjustable weight components, including weight bars and removable weight members, that allow for horizontal and vertical adjustment of the center of gravity, along with an adjustable sole member and hosel assembly, enabling precise control over face angle, loft, and lie angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable weighting mechanisms are added to golf club heads, then center of gravity adjustability is improved, but device complexity increases
Solution Approach 1:
The weighting system is divided into separate modular components: multiple discrete weight members (different densities and configurations) that can be independently selected and positioned in weight ports distributed across the club head. This segmentation allows flexible CG adjustment without requiring complex mechanical mechanisms, as weights can be simply added, removed, or repositioned between ports.
Solution Approach 2:
The patent extends CG adjustment from traditional single-axis (vertical) control to multi-dimensional control by distributing weight ports across multiple locations and orientations in the club head. This includes vertical ports for loft adjustment, horizontal ports for face angle control, and varied depth positions for lie angle optimization, enabling three-dimensional CG manipulation through strategic weight placement.
2Adaptability or versatility
If multiple weight ports are distributed across the club head, then center of gravity adjustment flexibility is improved, but manufacturing precision requirements increase
Solution Approach 1:
Different regions of the club head are equipped with weight ports having specific local characteristics optimized for their function. For example, ports are positioned at precise locations on the sole, crown, and hosel areas, each with specific orientations and depths tailored to control particular performance parameters (loft, lie, face angle) independently, allowing localized adjustment without affecting the entire club head structure.
3Adaptability or versatility
If weight members of different densities are used, then center of gravity adjustment range is improved, but device complexity increases
Solution Approach 1:
The system employs weight members constructed from different materials with varying densities (e.g., tungsten, stainless steel, aluminum) to achieve diverse weight values and CG positions. This material diversity allows fine-tuned adjustment across a broad range without requiring excessively large or small weight components, as density variations enable precise control with compact weight members.
