Adjustable Weight Insert for Golf Club Head Center of Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club designs face challenges in optimizing weight distribution and center of gravity to enhance playability and distance, particularly in wood-type clubs, where environmental factors and golfer-specific issues affect performance.
Innovation Solution
A golf club head design featuring a weighted insert with a heavy end and a lighter end, adjustable along a longitudinal axis, and a locking mechanism allowing rotation to adjust the center of gravity along the x-axis and z-axis, utilizing a spring to secure the insert and facilitate easy orientation within a cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-piece construction is used to facilitate access to the cavity for attaching components and adjusting weights, then ease of operation and adaptability improve, but device complexity increases due to multiple joining operations and components
Solution Approach 1:
The club head is divided into multiple pieces including a body, crown, and sole that are joined together to form a hollow cavity. This segmentation allows access to the cavity for inserting and adjusting weight components while maintaining structural integrity through welding or other joining methods.
Solution Approach 2:
The club head incorporates adjustable weight components that can be repositioned within the cavity to dynamically change the center of gravity and weight distribution. This dynamic adjustment capability allows the club to be adapted to different playing conditions and golfer preferences.
2Manufacturing precision
If adhesive is injected into the club head to provide correct swing weight and retain debris, then manufacturing precision and reliability improve, but device complexity increases due to the additional injection process and material
Solution Approach 1:
Adhesive material is injected into the hollow cavity of the club head to precisely adjust the swing weight by adding or removing material as needed. The adhesive serves dual purposes of weight adjustment and debris retention, optimizing the club's performance characteristics.
3Strength
If titanium material is used to enhance the performance of the club face, then strength and durability improve, but weight increases which may affect the overall club head weight distribution
Solution Approach 1:
Titanium material is specifically used for the club face to enhance its strength, durability, and performance characteristics. The rest of the club head body can be constructed from lighter materials, allowing the heavy titanium to be localized only where needed for face performance while managing overall weight through strategic material placement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for precise adjustment of the club's center of gravity, improving playability and ball flight characteristics by optimizing weight distribution, enhancing distance and control, and accommodating various golfer preferences and environmental conditions.
Implementation Method 1
A spring may be located in the cavity and configured to force the weighted insert away from the terminal end of the cavity
Implementation Method 2
The insert locking feature is configured to engage the head locking feature as the insert locking feature is rotated relative to the head locking feature
