Golf Club Head Alignment Features for Consistent Shot Spin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club manufacturing methods lead to variability in alignment features, affecting performance consistency due to imprecise application of masking stickers, resulting in inconsistent alignment and spin characteristics.
Innovation Solution
Incorporation of precise alignment features using orthogonal axes and contrasting shades or colors on the golf club head, including primary and secondary alignment features, electronic displays, and dielectric coatings to enhance alignment accuracy and consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If masking stickers are used to guide painting of alignment features, then the alignment feature can be applied, but the positioning precision and consistency vary between club heads
Solution Approach 1:
The club head body itself provides the alignment reference through molded-in features (protrusions, recesses, or integral structures) that automatically guide the positioning of alignment features without requiring external masking stickers or guides. The alignment feature is applied relative to these self-provided reference features, ensuring consistent positioning across all club heads.
Solution Approach 2:
The alignment reference features are integrated into the club head body structure itself rather than being separate external elements. The protrusions, recesses, or molded features are formed as part of the club head manufacturing process, merging the reference system with the club head body to eliminate variability in positioning.
2Reliability
If alignment features are painted using manual masking methods, then alignment features can be created, but variability in shape and angle occurs between club heads
Solution Approach 1:
The club head body provides self-contained alignment reference features (protrusions, recesses, or molded structures) that define the exact shape and angle of alignment features. These reference features are integral to the club head design and ensure that all alignment features are manufactured with identical geometry and orientation, eliminating variability.
Solution Approach 2:
The alignment reference features are designed with specific geometric parameters (angles, positions, dimensions) that are precisely controlled during club head manufacturing. By defining these parameters in the club head body design, the alignment features automatically inherit consistent shape and angle characteristics across all produced clubs.
3Productivity
If masking stickers are used for alignment feature application, then painting guidance is provided, but the method is time-consuming and reduces productivity
Solution Approach 1:
The club head body contains built-in alignment reference features that are automatically visible and accessible during the painting process. Workers can directly use these molded-in protrusions, recesses, or structures as guides without needing to apply masking stickers, significantly reducing preparation time while maintaining consistent alignment feature positioning.
Solution Approach 2:
The alignment reference features are pre-formed as integral parts of the club head body during the molding or manufacturing process. This preliminary creation of reference features eliminates the need for subsequent masking and positioning steps, allowing alignment features to be applied quickly and accurately in a single operation.
