Golf Club Head with Interchangeable Weights for Center of Gravity Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf clubs lack the ability to adjust the location of the center of gravity without compromising the flexibility in the design of the club head, limiting customization options for golfers.
Innovation Solution
A golf club design featuring a golf club head with two detachable weight members and fasteners that allow for interchangeable positions, enabling adjustment of the center of gravity by using the shaft attachment hole for either weight member, reducing the number of holes required on the bottom side and enhancing design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple holes are provided on the bottom side of the club head for weight member attachment, then the center of gravity can be adjusted to various positions, but the design flexibility and structural simplicity are reduced
Solution Approach 1:
The shaft insertion hole's lower opening is designed to serve dual purposes: as the shaft insertion hole for attaching the shaft to the club head, and as a weight member attachment hole for fixing weight members to adjust the center of gravity. This multi-functional design eliminates the need for separate holes, maintaining adaptability while reducing structural complexity
Solution Approach 2:
The invention merges the shaft insertion hole and the weight member attachment hole into a single hole structure. The lower opening of the shaft insertion hole is combined with the weight member attachment hole, allowing both the shaft and weight members to be attached through the same hole, thereby reducing the total number of holes required in the club head
2Device complexity
If the shaft insertion hole is also used as a weight member attachment hole, then the number of holes is reduced and design flexibility is improved, but the reliability of shaft attachment may be compromised
Solution Approach 1:
The shaft insertion hole is segmented into an upper opening and a lower opening, where the upper opening is dedicated to shaft insertion and the lower opening serves as the weight member attachment hole. This segmentation allows the shaft attachment function and weight member attachment function to be spatially separated within the same hole structure, ensuring that shaft attachment reliability is maintained while enabling weight member attachment
Solution Approach 2:
The lower opening of the shaft insertion hole acts as an intermediary element that connects both the shaft attachment system and the weight member attachment system. By using this intermediate structure, the patent enables dual functionality without compromising the primary shaft attachment function, as the upper opening remains dedicated to shaft insertion while the lower opening accommodates weight members

AI summary
A golf club includes a golf club head provided with a first hole and a second hole on its bottom side, a shaft detachably fixed to the golf club head, a weight member comprising a first weight member and a second weight member each detachably fixed to the golf club head, and a faster including a first fastener for fixing the shaft and the first weight member to the golf club head through the first hole, and a second fastener for fixing the second weight member to the golf club head through the second hole. The first weight member and the second weight member are configured as mutually replaceable weights so that the first weight member is fixed to the second hole using the second fastener and the second weight member is fixed to the first hole using the first fastener.
