Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf clubs and other ball striking devices experience undesirable effects such as reduced velocity, inconsistent ball flight, and increased vibration due to off-center impacts, which existing technologies fail to adequately address.
Innovation Solution
A ball striking device with a face member and a weight member connected by a resilient member, allowing for efficient transfer of momentum during impacts, including off-center strikes, through the use of a configuration where the weight member is positioned to incrementally transfer momentum based on the impact location relative to the center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ball impacts the face member away from the center of gravity, then the ball striking device can still function, but velocity transfer is reduced, ball flight becomes inconsistent, and vibration increases
Solution Approach 1:
The weight member acts as an intermediary between the face member and the club body, specifically positioned and configured to transfer momentum from off-center impacts more effectively to the club body, thereby maintaining energy transfer efficiency and performance consistency across various impact locations
Solution Approach 2:
The patent modifies the mass distribution parameters by adding a weight member with specific weight and positioning relative to the center of gravity, changing the moment of inertia and mass distribution to improve performance on off-center impacts while managing vibration characteristics
2Loss of energy
If a weight member is added to improve momentum transfer, then energy transfer efficiency improves, but the device complexity increases
Solution Approach 1:
The weight member is integrated with the face member assembly rather than being a completely separate component, combining the functions of momentum transfer and structural support in a single integrated element that attaches to the club body, thereby improving energy transfer while limiting the increase in device complexity
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 solution enhances energy transfer and reduces twisting of the face, resulting in more consistent ball flight and minimized energy loss on off-center impacts, maintaining performance across various impact locations.
Implementation Method 1
The weight member may transfer momentum to the face member upon impact, and the amount of momentum transferred to the face member may increase incrementally with a lateral distance of a location of the impact away from a center of gravity of the face member
Implementation Method 2
The resilient member is compressible to permit the weight member to transfer momentum to the face member through the resilient member upon an impact of the ball on the striking surface

AI summary
A head for a ball striking device, such as a golf club head, includes a face member having a face with a striking surface configured for striking a ball and a rear surface opposite the striking surface, a weight member connected to the face member behind the rear surface of the face member, and a resilient member positioned between the weight member and the face member. The resilient member is connected to the rear surface of the face member to connect the weight member to the face member. The resilient member is compressible to permit energy and/or momentum to be transferred between the weight member and the face member through the resilient member during impact, including an off-center impact on the striking surface. Momentum transferred from the weight member to the face member during an off-center impact may reduce energy loss and twisting of the face on impact.
