Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads do not effectively accommodate various golf swing types, leading to inconsistent performance in terms of launch angle, spin rate, and direction of the golf ball.
Innovation Solution
A golf club head design featuring multiple weight portions and configurations that allow for adjustable center of gravity and moment of inertia, enabling it to accommodate different swing styles and optimize launch trajectory and forgiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed weight configuration is used in golf club heads, then the manufacturing process is simple, but the club cannot accommodate various golf swing types leading to inconsistent performance
Solution Approach 1:
The club head is divided into multiple weight portions (first weight portion, second weight portion, third weight portion) that can be independently positioned within respective weight ports. This segmentation allows each weight portion to be adjusted to specific locations to accommodate different swing types, resolving the contradiction between adaptability and structural complexity by making the complexity modular and functional rather than monolithic.
Solution Approach 2:
The weight portions are made adjustable and repositionable within the club head structure, transforming the static weight configuration into a dynamic system. This allows the center of gravity and moment of inertia to be changed based on the golfer's swing type, achieving adaptability while managing complexity through a systematic adjustment mechanism rather than multiple fixed configurations.
2Manufacturing precision
If multiple weight portions are added to customize center of gravity, then launch trajectory control is improved, but manufacturing complexity increases
Solution Approach 1:
The manufacturing process is segmented into distinct stages: forming the base club head structure, creating separate weight portions, and assembling them in specific configurations. This segmentation allows each component to be manufactured independently with standard precision, then assembled to achieve the required center of gravity positioning accuracy, thereby improving manufacturing precision without proportionally increasing overall manufacturing complexity.
Solution Approach 2:
Different weight portions are placed in specific locations (first weight port, second weight port, third weight port) to achieve precise center of gravity control for different swing types. This local quality approach allows the manufacturing process to use standardized components with consistent properties, while the precision is achieved through the strategic local arrangement of these components rather than requiring high precision in every manufacturing step.
3Reliability
If weight portions are made adjustable for different swings, then performance consistency is improved, but device complexity increases
Solution Approach 1:
The weight portions are designed to be adjustable within the club head, allowing the center of gravity and moment of inertia to be dynamically changed to match different swing types. This dynamic capability ensures consistent performance across various swings by optimizing the weight distribution for each swing type, while the adjustment mechanism is kept relatively simple through the use of standardized weight ports and interchangeable weight portions.
Solution Approach 2:
The club head design incorporates multiple weight portions that can be arranged in different configurations to serve multiple functions: accommodating draw swings, fade swings, and neutral swings. This multi-functionality allows a single club head structure to provide consistent performance across different swing types without requiring multiple specialized club heads, thereby improving reliability while managing device complexity through a universal adjustable platform.

AI summary
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head includes a body portion, a crown portion having a composite material, a first groove on a bottom portion extending in a heel-to-toe direction, a second groove on the bottom portion extending in a heel-to-toe direction, a first set of ports on the bottom portion between the first groove and the second groove, a second set of ports on the bottom portion between the second groove and a rear portion, and a filler material in the body portion between the first groove and the rear portion. The filler material at least partially surrounds the first set of ports and the second set of ports. Other examples and embodiments may be described and claimed.
