Dual-Material Golf Club Face Grooves for Customized Feel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf clubs, particularly putters and irons, lack sufficient customization to cater to individual player preferences and swing characteristics, affecting the 'feel' and performance.
Innovation Solution
Golf club heads with a ball striking face featuring a combination of materials with different hardnesses, including alternating grooves with edges formed from these materials, to enhance sensory feedback and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-material design is used for the ball striking face, then manufacturing is simpler and cost is lower, but the club lacks customization capability and sensory feedback variety
Solution Approach 1:
The ball striking face is segmented into multiple regions with different materials (e.g., softer material in the center, harder material at the periphery) to provide differentiated sensory feedback and performance characteristics for different areas of contact
Solution Approach 2:
Different regions of the ball striking face are assigned different material properties (hardness, elasticity) to optimize local performance - softer materials for comfort and feel, harder materials for durability and ball control
2Ease of operation
If grooves are formed entirely from a single material, then manufacturing is easier, but the groove edges cannot provide differentiated tactile feedback
Solution Approach 1:
The grooves are segmented into multiple sections with different material compositions, creating distinct tactile zones along the groove length that provide varied sensory feedback during ball contact
Solution Approach 2:
The grooves utilize composite material structures combining different materials (e.g., polymer and metal, or materials with different hardness levels) to create edges that provide differentiated tactile sensations while maintaining structural integrity

AI summary
The invention is a golf club head with a ball striking face including a plurality of recesses, a plurality of first grooves, and a plurality of second grooves that extend between a heel edge and a toe edge of the club head. The ball striking face includes a first material, for example a metal material, and the plurality of recesses are filled with a fill material, for example a polymer material. The depth of the grooves, the height of the grooves, the fill material, and the positioning of the grooves can all affect the performance of the club head. In some embodiments, the club head is a putter-type club head.
