Golf Club Weight Assembly With Sliding Cover Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club designs face challenges in securely and selectively adjusting the center of gravity (CG) and moment of inertia (MOI) through weight placement, which affects flight characteristics such as fades, draws, launch angles, ball spin, and speed, without causing undesirable movement or loss of components during adjustments.
Innovation Solution
A golf club head with a recessed channel and a weight assembly that includes a slidable weight, a cover, and a fastener, where the fastener indirectly secures the weight within the channel through the cover, allowing for fine-tuning of CG and MOI by sliding the weight without direct engagement, reducing movement, and enabling quick adjustments without detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weights are directly engaged and secured within the recessed channel, then the weight placement is secure and stable, but the adjustment process becomes complex and requires detachment of components
Solution Approach 1:
The cover acts as an intermediary component between the fastener and the weight. The fastener indirectly secures the weight through the cover, which slides over the weight within the recessed channel. This intermediary mechanism allows secure weight placement while enabling simple adjustment by merely sliding the cover along the channel without requiring detachment of components.
2Reliability
If the fastener directly engages the weight, then the weight is securely held, but the adjustment process requires component detachment and increases complexity
Solution Approach 1:
The cover serves as a mediator that the fastener engages with, rather than directly engaging the weight. This allows the weight to be securely held through the cover while enabling easy adjustment by sliding the cover along the recessed channel, improving ease of operation without compromising weight securing.
Solution Approach 2:
The cover is designed to be dynamically movable along the recessed channel while maintaining engagement with the fastener. This dynamic capability allows the weight position to be easily adjusted by sliding the cover to different locations along the channel, making the adjustment process simple and quick.
3Reliability
If the cover fully covers the recessed channel, then component protection is improved, but the weight cannot be adjusted without removing the cover
Solution Approach 1:
The cover is designed as a dynamic component that can slide along the recessed channel while remaining attached to the golf club head. This allows the cover to protect the weight and internal components while still permitting easy weight adjustment by simply sliding the cover to different positions along the channel, eliminating the need for complete removal.
4Reliability
If multiple fasteners are used to secure the cover, then the cover is firmly attached, but the device complexity and adjustment time increase
Solution Approach 1:
The fastening system is segmented into a minimal number of strategically positioned fasteners rather than using multiple fasteners along the entire cover. This segmentation approach provides sufficient attachment firmness while minimizing the number of fasteners that need to be manipulated during adjustment, thereby reducing adjustment time.

AI summary
A golf club head includes: a body having an outer surface; a recessed channel formed in the outer surface; and a weight assembly including: a weight at least partially disposed within the recessed channel and configured to move therein, a cover configured to engage with the body such that the cover at least partially covers the recessed channel; and a fastener selectively movable along a fastener axis, and configured to lockingly engage with an end of the cover.
