Twisted Golf Club Face Geometry and Adjustable Hosel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club designs struggle to maintain the appearance of traditional cavity back clubs while shifting the center of gravity toward the sole and perimeter, and they often compromise acoustical properties and hosel integrity during loft and lie adjustments.
Innovation Solution
The design incorporates a twisted striking face with specific loft and face angle variations across the club head, utilizing a titanium alloy with aluminum and molybdenum, and a hosel system that allows for adjustable loft, lie, and face angle, maintaining a traditional appearance while enhancing performance and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the center of gravity is shifted toward the sole and perimeter to improve forgiveness, then the appearance of traditional cavity back clubs is compromised
Solution Approach 1:
The patent applies local quality by creating a twisted face geometry where only specific regions of the club head have modified contours. The bulge and roll contours are varied across different zones of the face, allowing the center of gravity to shift toward the sole and perimeter for improved forgiveness while maintaining the traditional cavity back appearance in the overall structure.
2Adaptability or versatility
If the hosel is made adjustable for loft and lie, then the structural integrity and acoustical properties are compromised
Solution Approach 1:
The patent applies dynamics by implementing an adjustable hosel mechanism that allows the loft, lie, and face angle to be modified after manufacturing. The hosel includes a removable insert system with multiple positioning options, enabling golfers to adjust club specifications while maintaining structural integrity through precision-machined interfaces and secure retention mechanisms.
3Reliability
If the face contours are varied to counteract gear effect, then the manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by systematically varying the bulge and roll contour parameters across different regions of the club face. The twisted face geometry is defined by specific mathematical relationships between the contours at different locations, allowing complex performance characteristics to be achieved through controlled parameter variation rather than arbitrary shaping.

AI summary
An iron-type golf club head has a hosel portion, a heel portion, a sole portion, a toe portion, a topline portion, and a striking face including a center face location. A toe side topline-to-sole contour of the striking face is more lofted than a center face topline-to-sole contour of the striking face, a heel side topline-to-sole contour of the striking face is less lofted than the center face topline-to-sole contour, a topline side toe-to-heel contour of the striking face is more open than a center face toe-to-heel contour of the striking face, and a sole side toe-to-heel contour of the striking face is more closed than the center face toe-to-heel contour. The toe side topline-to-sole contour, the center face topline-to-sole contour, the heel side topline-to-sole contour, the topline side toe-to-heel contour, the center face toe-to-heel contour, and the sole side toe-to-heel contour are straight line contours.
