Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads face challenges in achieving improved energy transfer, straighter shots, and durability while maintaining sound and feel, as traditional materials like fiber-based composites compromise durability and acoustic properties.
Innovation Solution
A golf club head design featuring a multi-material striking face with a perimeter portion made of a high-density material and a central portion filled with a lightweight, composite material insert, optimized for weight savings and durability, using a dovetail-shaped undercut for secure bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If fiber-based composite materials are used to reduce weight from the striking face, then weight is reduced allowing for improved MOI, but durability and acoustic properties are compromised
Solution Approach 1:
The patent applies composite materials by combining a fiber-based composite face insert with a metallic backing plate. The composite insert (e.g., carbon fiber reinforced polymer) provides weight reduction for improved MOI, while the metallic backing plate (titanium or stainless steel) ensures durability and maintains acoustic properties. This composite structure resolves the contradiction by integrating materials with complementary properties.
Solution Approach 2:
The patent implements local quality by using different materials in different regions of the striking face. The central impact area uses the lightweight composite material for weight savings, while the perimeter and backing structure use metallic materials for strength and acoustic performance. This spatial differentiation allows each region to contribute its optimal properties to the overall performance.
2Weight of moving object
If weight is removed from the striking face to improve MOI, then ability to hit golf ball straighter is improved, but structural integrity and durability may be compromised
Solution Approach 1:
The composite face insert combined with metallic backing plate creates a structurally integrity while maintaining weight reduction. The composite material provides sufficient strength for weight savings, while the metallic backing plate reinforces the structure to prevent deformation and maintain durability during impact.
Solution Approach 2:
The patent changes material parameters (density, strength, stiffness) by selecting specific composite and metallic materials with optimized properties. The composite material has lower density for weight reduction, while the metallic backing plate has higher strength and stiffness to maintain structural integrity. This parameter optimization resolves the contradiction between weight and strength.

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.
