Golf Club Head Keel Adjuster for Resting Face Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club performance is affected by the position of the center of gravity and resting face angle, which existing golf clubs struggle to adjust effectively, leading to inconsistent ball flight and increased likelihood of hooks or slices.
Innovation Solution
A golf club head with a multi-component resting face angle adjuster that includes a recess and an adjustment member with a keel surface, allowing for adjustable positioning between different keel points on the sole to alter the resting face angle, thereby influencing the club's orientation at address.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the resting face angle is fixed in traditional golf clubs, then the structure is simple and easy to manufacture, but the ball flight consistency deteriorates and hooks or slices occur more frequently
Solution Approach 1:
The patent applies the dynamics principle by making the keel point adjustable rather than fixed. The adjustment member can be repositioned along the sole of the club head, allowing the keel point location to change dynamically. This enables the resting face angle to be adjusted according to player preferences and course conditions, improving ball flight consistency while managing the added structural complexity through a relatively simple sliding mechanism.
2Reliability
If an adjustable keel point mechanism is added to modify resting face angle, then ball flight consistency improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the club head into distinct functional components: the club head body, the adjustment member, and the keel point feature. This modular approach allows each component to be manufactured separately using standard processes, then assembled together. The adjustment member can be produced independently and inserted into the club head, simplifying manufacturing compared to creating a fully integrated adjustable mechanism.
3Adaptability or versatility
If the adjustment member is positioned at different locations on the sole, then the resting face angle can be customized, but the precision required for positioning increases
Solution Approach 1:
The patent applies partial action by providing a limited number of discrete positioning locations for the adjustment member along the sole, rather than allowing continuous adjustment. This approach offers sufficient versatility for customization while avoiding the need for high-precision manufacturing that would be required for continuous adjustment. The adjustment member can be positioned at predetermined locations that provide adequate range for different playing styles without requiring sub-millimeter precision.

AI summary
A golf club head includes a club body and a resting face angle adjuster. The club body includes a crown opposite a sole, a toe end opposite a heel end, a back end opposite a face, and a hosel. The sole includes a sole surface. The resting face angle adjuster includes an adjustment member having a keel surface, and a recess formed in the sole such that a portion of the sole surface at least partially bounds the recess. The adjustment member is disposed in the recess and positionable between a first adjustment position and a second adjustment position. In the first adjustment position, the keel surface is at a first distance relative to the portion of the sole surface. In the second adjustment position, the keel surface is at a second distance relative to the portion of the sole surface not equal to the first distance in the direction.
