Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club designs face challenges in creating a striking face that saves weight, improves Coefficient of Restitution (COR), and maintains durability without sacrificing sound and feel, particularly in bonding fiber-based composite materials with metallic materials under high stress conditions.
Innovation Solution
A golf club head design featuring a multi-material striking face with a perimeter made of a dense material and a central portion filled with a lighter material of lower density, utilizing a dual-layered construction and a dovetail shaped undercut to enhance bonding and durability, while maintaining acoustic characteristics similar to a metallic face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If fiber-based composite materials are used to form the striking face, then weight is saved and COR is improved, but durability and bonding reliability under high stress deteriorate
Solution Approach 1:
The patent employs a hybrid composite structure combining fiber-based composite material (for weight savings and COR improvement) with metallic material (for durability and bonding reliability). The fiber-based composite forms the primary striking face while metallic components provide structural support and bonding interfaces, creating a multi-material composite system that resolves the contradiction between lightweight performance and bonding reliability.
Solution Approach 2:
The patent applies different materials to different regions of the striking face: fiber-based composite material is used in areas requiring weight savings and COR enhancement, while metallic material is strategically placed in regions requiring superior bonding reliability and stress resistance. This localized material differentiation allows each zone to optimize for its specific functional requirements.
2Weight of moving object
If fiber-based composite materials are used to form the striking face, then weight is saved and COR is improved, but sound and feel characteristics deteriorate
Solution Approach 1:
The hybrid composite structure combines fiber-based composite material (providing weight savings and COR improvement) with metallic material (providing desirable sound and feel characteristics). The metallic components contribute to the acoustic properties and tactile feedback during impact, compensating for the limitations of fiber-based composites while maintaining the weight and performance benefits.
3Stability of the object's composition
If weights are added to the rear perimeter to increase MOI, then ability to hit ball straighter improves, but overall weight of club head increases
Solution Approach 1:
The patent segments the club head into distinct functional zones with different material assignments. The striking face uses lightweight fiber-based composite material, while strategic metallic components are placed in the rear perimeter to increase MOI. This segmentation allows weight optimization in the face while concentrating mass in specific rear locations to enhance stability without proportionally increasing overall weight.
Solution Approach 2:
The patent applies local quality by using fiber-based composite material in the striking face for weight savings while placing metallic material with higher density in the rear perimeter regions to increase Moment of Inertia. This localized material distribution optimizes both weight and stability characteristics independently.

AI summary
A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components. The insert may be bonded to the frontal pocket using an adhesive impregnated within a glass fiber weave.
