Adjustable Weight Golf Club Head Center of Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club head designs lack adjustable weight systems, making it difficult to fine-tune performance characteristics such as center of gravity and moment of inertia to suit individual golfer preferences.
Innovation Solution
A golf club head with a position-adjustable weight system, featuring an adjustable weight that can be locked or unlocked by rotating a fastener, allowing the center of gravity to be manipulated along specific axes, thereby enhancing playability and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed weight system is used in the club head, then the manufacturing process is simple, but the ability to fine-tune performance characteristics is limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the static fixed weight system into a dynamic adjustable weight system. The weight can be repositioned along the sole of the club head using a threaded fastener mechanism, allowing the center of gravity to be adjusted according to different performance requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent applies segmentation by separating the weight component from the main club head body. The weight is made as a distinct, movable component that can be independently positioned and adjusted, rather than being permanently fixed within the club head structure. This allows for flexible reconfiguration without redesigning the entire club head.
2Adaptability or versatility
If the weight position is made adjustable, then performance can be customized, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies self-service through the threaded fastener mechanism that allows the user to self-adjust the weight position. The system includes its own adjustment mechanism integrated into the design, eliminating the need for external tools or complex assembly procedures. The threaded bore and fastener create a self-contained adjustment system that maintains precision through its mechanical design.
3Ease of operation
If a simple fastening mechanism is used, then ease of operation is improved, but reliability of weight retention may be compromised
Solution Approach 1:
The patent replaces simple mechanical fastening with a threaded fastener system that combines ease of operation with high reliability. The threaded engagement provides secure retention through friction and mechanical interlocking, while still allowing for simple rotational adjustment. This substitution of the fastening mechanism type resolves the contradiction between simplicity and reliability.
