Golf Club Head Alignment Line for Face Angle Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club face angle appearance can mislead golfers, as the visual appearance of the club at address does not accurately represent the actual face angle, leading to incorrect swing techniques.
Innovation Solution
A wood-type golf club head with an alignment line that extends from the heel end to the toe end, featuring a visually distinct color and width, strategically positioned at the junction of the crown and front portions, allowing the face angle to appear open, closed, or square depending on the actual angle, thereby correcting the perceived face angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the face angle is closed to improve shot accuracy, then the actual face angle is closed, but the visual appearance at address shows an open face angle, causing golfers to swing incorrectly
Solution Approach 1:
The patent applies color changes by introducing an alignment line with a color that is visually distinct from the crown portion (e.g., white line on black crown). This color contrast creates a visual reference that allows golfers to perceive the actual face angle correctly, resolving the contradiction between the closed face angle setting and the misleading open appearance.
Solution Approach 2:
The alignment line serves as an intermediary visual element between the closed face angle and the golfer's perception. It mediates the information gap by providing a reference marker that indicates the true face angle position, enabling golfers to adjust their swing accordingly despite the closed angle setting.
2Measurement precision
If the face angle is open to improve shot accuracy, then the actual face angle is open, but the visual appearance at address shows a closed face angle, causing golfers to swing incorrectly
Solution Approach 1:
The alignment line with its contrasting color (e.g., white on black) creates a visual reference that accurately represents the open face angle position. This color contrast ensures that when the face angle is opened for accuracy, the visual appearance correctly reflects this change, preventing golfers from swinging based on misleading closed appearance cues.
3Measurement precision
If the face angle is square for accuracy, then the actual face angle is square, but the visual appearance may be misleading, causing incorrect swings
Solution Approach 1:
The alignment line acts as an intermediary visual indicator that clearly shows the square face angle position. By providing a distinct visual reference point, it ensures that when the face angle is set to square for accuracy, golfers can visually confirm this position and swing accordingly, eliminating misleading visual information.
4Measurement precision
If an alignment line is added to correct face angle appearance, then visual accuracy is improved, but the device complexity increases
Solution Approach 1:
The alignment line is implemented as a separate, discrete element from the crown portion, allowing it to be added independently without redesigning the entire club head structure. This segmentation approach improves visual accuracy while minimizing the increase in device complexity, as the alignment line can be incorporated through simple manufacturing processes like insert molding or surface application.

AI summary
A golf club having a golf club head with an alignment line that makes the actual face angle of the golf club appear differently when the golf club is at address. The golf club head preferably has a white line at a face-crown junction which changes the appearance of the face angle while the golf club is at address. The golf club head is preferably a driver or fairway wood, and preferably has a volume of 250 cubic centimeters to 475 cubic centimeters.
