Golf Club Head Alignment With Rotatable Hosel Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers often suffer from natural visual deviations that lead to misalignment of the club face, resulting in errant shots and additional strokes.
Innovation Solution
A system and method that adjusts the angle of the club face relative to the club shaft using a hosel fitting and neck rotation, incorporating a laser alignment aid to correct for visual inaccuracies, with a raised sight line providing visual guidance without revealing the adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the club face is adjusted to compensate for visual deviation, then alignment accuracy is improved, but the visual appearance of straight alignment is lost
Solution Approach 1:
A laser alignment aid is introduced as an intermediary tool to project a reference line that accounts for the golfer's visual deviation. The laser provides an objective alignment reference that compensates for the subjective visual inaccuracy, allowing the club face to be aligned correctly while the golfer still perceives straight alignment through the laser guide.
Solution Approach 2:
The system changes the alignment parameter by introducing a deliberate angular offset between the club shaft axis and the club face normal. This parameter change compensates for the golfer's visual deviation, transforming the alignment from apparent straightness to actual accuracy by adjusting the reference frame used for alignment.
2Adaptability or versatility
If the neck is made rotatable for adjustment, then adaptability is improved, but structural stability deteriorates
Solution Approach 1:
The neck is designed with dynamic characteristics, allowing rotation during the adjustment phase to enable club face angle modification. Once adjustment is complete, the neck transitions to a stable locked position using an interference fit mechanism, providing structural stability for swing execution. This dynamic design allows the system to switch between adjustable and stable states as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures accurate club face alignment, allowing golfers to consistently strike the ball along the intended path, reducing errant shots and improving overall performance.
Implementation Method 1
the open interior is dimensioned to receive a laser unit therein, wherein powering of the laser causes a light beam to extend outwardly of the club face through the aperture

AI summary
A system for adjusting alignment of a golf club head includes a club shaft having a proximal end and an opposing distal end, with a hosel fitting fixedly secured to the distal end of the club shaft. A neck is rotationally coupled to the hosel fitting at a first end and a club head is coupled to the second end of the neck. The hosel fitting includes a reference line and the neck includes a series of angle index lines. The angle of the club face is adjusted by selectively aligning a singled angle index line with the reference line.
