Wedge Golf Club Head Center of Gravity Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wedge type golf club designs do not maximize backspin and ball speed due to a high center of gravity location, which limits the efficiency of energy transfer between the club head and the golf ball, and existing methods to increase backspin often suffer from wear and tear or require adjustments to grooves or surface treatments.
Innovation Solution
A wedge type golf club head with a center of gravity located substantially along a neutral axis, preferably behind the hitting surface, and incorporating a weighted sole with a higher density material to lower the center of gravity, optimizing energy transfer and performance characteristics such as backspin, ball speed, and launch angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the center of gravity is located higher in traditional wedge designs, then the club head is easier to manufacture with conventional weight distribution, but the energy transfer efficiency to the golf ball is reduced, limiting backspin and ball speed
Solution Approach 1:
The patent changes the positional parameter of the center of gravity from a conventional higher location to a lower location (5-15mm from the ground), fundamentally altering the weight distribution parameters to optimize energy transfer while maintaining manufacturability through adjusted sole configuration
Solution Approach 2:
The patent employs composite construction by combining a metallic club head body with a separate high-density material weight (tungsten, lead, or steel) in the sole, allowing independent optimization of the weight position and distribution without compromising the overall structural integrity or manufacturing process
2Productivity
If surface treatments or groove configurations are added to increase backspin, then the coefficient of friction is improved, but the treatments suffer from gradual wear and tear reducing effectiveness over time
Solution Approach 1:
The patent extracts the backspin generation function from the club face surface treatments and grooves, relocating it to the center of gravity positioning in the sole. This separates the spin generation mechanism from the wear-prone hitting surface, making it dependent on the durable structural weight placement instead
Solution Approach 2:
The optimized center of gravity positioning creates a self-sustaining backspin mechanism that does not require additional surface treatments or grooves. The club head structure itself generates the necessary friction and spin through its weight distribution and impact dynamics, eliminating the need for maintenance-prone additive features
3Speed
If additional loft is added to maintain shot distance, then the launch angle is improved, but the center of gravity location must be adjusted to maintain constant distance without compromising spin
Solution Approach 1:
The high-density weight in the sole acts as a counterbalance that stabilizes the center of gravity position. When additional loft is added to increase launch angle, the counterweight ensures the center of gravity remains in the optimal lower position, preventing loss of spin rate while allowing the loft adjustment for improved launch
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
The optimized center of gravity location improves energy transfer, resulting in increased backspin, ball speed, and launch angle, enhancing the overall performance of the golf shot while maintaining shot distance and accuracy, and allowing for additional loft to maintain constant distance without compromising spin.
Implementation Method 1
a center of gravity of the wedge type golf club head is located behind the hitting surface substantially along the neutral axis
Implementation Method 2
This increased loft angle in wedges generally yield a golf shot with a higher trajectory because of the impact surface with the golf ball is not perpendicular to the trajectory of the club head; but rather, the golf ball interacts with the wedge at an inclination closely resembling the actual loft angle of the wedge itself. This inclination generally causes the golf ball to move up along the inclination of the wedge when struck by the wedge type golf club head, creating a backward rotation of the golf ball as it leaves the wedge club face.
Implementation Method 3
one method to generate increased backspin may be increasing the coefficient of friction of the wedge club face
