Removable Golf Club Crown Weight System for Center of Gravity Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers experience difficulties in consistently hitting the ball in the intended direction and with desired flight paths, particularly with long-distance clubs like drivers and woods, due to challenges in accurately positioning the center of gravity in existing golf club designs.
Innovation Solution
The design of wood-type golf club heads featuring a removable weight portion with weight inserts that can be strategically positioned to alter the center of gravity, allowing for customization to correct swing flaws and optimize ball flight, including the use of a crown portion with a fixed and removable weight member, and a frame member to support the weight inserts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If weight is fixed in the club head body, then manufacturing is simpler, but adaptability for different swing corrections is reduced
Solution Approach 1:
The weight system is divided into separate components: a weight member with multiple receptacles and interchangeable weight inserts. This segmentation allows the club head to be manufactured with integrated receptacles while enabling post-manufacturing customization of the center of gravity position by inserting weights into different receptacles, thus resolving the contradiction between manufacturing simplicity and adaptability.
Solution Approach 2:
The weight system transitions from a static, fixed weight configuration to a dynamic, adjustable configuration. The weight member with multiple receptacles and interchangeable inserts enables the center of gravity to be repositioned based on different swing correction needs, providing adaptability while maintaining a simple manufactured base structure.
2Measurement precision
If center of gravity is positioned to correct ball flight, then accuracy improves, but requires complex weight adjustment mechanisms
Solution Approach 1:
The weight correction system is segmented into a weight member with multiple receptacles and separate interchangeable weight inserts. This allows precise center of gravity positioning for different ball flight corrections (draw, fade, straight) while keeping the adjustment mechanism simple - golfers only need to swap inserts rather than manipulate complex mechanisms.
Solution Approach 2:
The system enables change in the positional parameters of the center of gravity by inserting weights into different receptacles located at specific positions in the club head body. This allows precise adjustment of the center of gravity coordinates to correct various ball flight inaccuracies without requiring complex adjustment mechanisms.

AI summary
Wood-type golf club heads (e.g., drivers, fairway woods, wood-type hybrid clubs, or the like) include: (a) a ball striking face; (b) a club head body engaged or integrally formed with the ball striking face, wherein the club head body includes a crown portion, the crown portion including a fixed portion proximal to the ball striking face, and a removable weight portion, which is configured to be coupled with the fixed portion on a side of the crown potion away from the ball striking face. The club head body may further include an interior portion with a frame member defined therein. The crown weight may further include a weight member attached to the frame member, the weight member including at least one receptacle defined therein. The removable weight portion may further include at least one weight insert supported within the weight member in the at least one receptacle.
