Golf Club Head Crown Structure for Low Weight and Impact Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads face challenges in achieving durability and lightweight properties, particularly in areas subject to impact forces such as the club face, while maintaining performance factors like center of gravity, moment of inertia, and coefficient of restitution.
Innovation Solution
A golf club head design incorporating a composite material crown portion with integrated stiffening features, including thin portions and multiple crown stiffening regions, to enhance structural integrity and reduce weight, while maintaining performance characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If composite materials are used in the club face area, then weight is reduced, but durability deteriorates
Solution Approach 1:
The patent applies different material properties to different regions of the club head. The composite material is specifically used in the crown portion where weight reduction is beneficial, while the face portion maintains traditional durable materials to withstand impact forces. This localized material selection resolves the contradiction by optimizing each region for its specific functional requirements.
Solution Approach 2:
The patent utilizes composite materials in the crown portion to achieve weight reduction while maintaining structural integrity. The composite construction allows for optimized strength-to-weight ratio in non-impact areas, resolving the contradiction between lightweight design and overall durability by applying composite materials strategically where they provide maximum benefit without compromising impact resistance.
2Weight of moving object
If the crown portion is made thinner, then weight is reduced, but structural integrity deteriorates
Solution Approach 1:
The crown portion is divided into multiple layers or plies of composite material, each contributing to the overall structural integrity. This segmented construction allows the thin crown to maintain strength through layered reinforcement, resolving the contradiction between reduced thickness for weight loss and maintained structural integrity through distributed material layers.
Solution Approach 2:
The patent changes the material parameters of the crown portion by using high-strength composite materials with optimized fiber orientation and density. These parameter changes allow the crown to be thinner while compensating for reduced thickness through enhanced material properties, thus resolving the contradiction between thinness for weight reduction and strength for structural integrity.
3Weight of moving object
If composite material is added to the club head, then weight distribution is improved, but manufacturing complexity increases
Solution Approach 1:
The composite material layers are pre-formed and pre-positioned in the mold during the manufacturing process, allowing for precise weight distribution and center of gravity positioning before final curing. This preliminary action resolves the contradiction by enabling complex weight optimization without proportionally increasing manufacturing complexity, as the material placement is established early in the process.
