Variable Depth Golf Club Grooves for Debris Clearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club head grooves have uniform depth and width, which may not effectively clear debris like water, sand, and grass between the ball and the club face across the entire club head, leading to inconsistent performance.
Innovation Solution
The golf club head features grooves with variable depth and width that progressively increase from the toe end to the heel end, providing a deeper or wider channel in specific areas to effectively clear debris, customizable for individual golfing styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If grooves have uniform depth and width, then manufacturing is simple, but debris clearing effectiveness is insufficient across the entire club head
Solution Approach 1:
The groove design implements local quality by varying depth and width across different regions of the club head. Grooves are deeper and wider at the heel end compared to the toe end, creating region-specific characteristics that optimize debris clearing where needed while maintaining manufacturing feasibility through systematic variation rather than complex customization.
Solution Approach 2:
The invention applies parameter changes by systematically varying groove depth and width parameters along the length of the club head. The groove depth increases from toe to heel, and width variations are implemented to create optimal channels for debris removal in different impact zones, transforming uniform parameters into graduated parameters for enhanced performance.
2Reliability
If grooves have variable depth and width, then debris clearing effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The variable groove design applies local quality by concentrating depth and width variations in specific regions where they are most needed for debris clearing. The heel end features deeper and wider grooves to handle larger debris volumes from that impact zone, while the toe end maintains shallower grooves, creating a graduated structure that improves effectiveness without requiring complete complexity across the entire club head.
Solution Approach 2:
The groove system is segmented into different zones along the club head length, with each zone having optimized depth and width characteristics. This segmentation allows the design to address debris clearing needs in different impact regions independently, creating a structured variation pattern that improves performance while maintaining manageable complexity through zoned design rather than random variation.
3Device complexity
If uniform grooves are used, then club head design is simple, but performance consistency across various playing conditions deteriorates
Solution Approach 1:
The graduated groove design implements local quality by tailoring groove characteristics to match the functional requirements of different club head regions. The heel end, which typically experiences different impact conditions and debris generation than the toe end, receives deeper and wider grooves to ensure consistent performance across various playing conditions, while the toe end maintains appropriate groove dimensions for its specific operational context.
Solution Approach 2:
The invention uses parameter changes to achieve performance consistency by systematically adjusting groove depth and width parameters across the club head. This graduated parameter variation ensures that each region of the club face has optimized groove characteristics for its specific impact zone, maintaining reliable performance across diverse playing conditions while avoiding the oversimplification of uniform grooves.
