Removable Golf Club Weight with Spring Clip Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads face challenges in maximizing peripheral weight and moment of inertia due to the centralization of mass, which affects distance and accuracy, and existing methods for selective mass placement can lead to delamination or corrosion issues.
Innovation Solution
A golf club head design featuring a removable weight system with a low-profile weight member and a locking mechanism that utilizes a spring clip and cam surface to securely attach the weight without protruding into the center, allowing for adjustable center of gravity and preventing dislodgment during impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If moveable weights are screwed into threaded ports in the club head body, then the mass characteristics can be manipulated by rearranging the weights, but the cylindrical shape of the weights and the receiving features necessarily moves a significant portion of the mass toward the center of the club head, which does not maximize the peripheral weight or the moment of inertia
Solution Approach 1:
The weight member is divided into separate functional components: a weight body for mass, a clip portion for attachment, and a locking mechanism for security. This segmentation allows the weight to be positioned peripherally without compromising attachment strength, maximizing moment of inertia while maintaining adaptability.
Solution Approach 2:
The weight member utilizes the peripheral dimension of the club head body by extending into the hollow interior space near the outer surface. This dimensional positioning places mass at the periphery rather than the center, increasing moment of inertia while maintaining the ability to manipulate mass characteristics through different weight configurations.
2Adaptability or versatility
If composite structures of multiple materials are used to selectively locate mass in the club head, then mass can be strategically placed, but the different materials must be coupled by welding, swaging, or bonding agents which may be subject to delamination or corrosion over time
Solution Approach 1:
The weight member is constructed as a single integrated piece or pre-assembled unit with the weight body, clip portion, and locking mechanism functioning together as one component. This eliminates the need for field coupling of multiple materials, preventing delamination and corrosion issues while maintaining strategic mass placement capability.
Solution Approach 2:
Instead of coupling multiple materials together to create the weight structure, the invention uses a single material construction for the weight member itself, reversing the approach of multi-material composites. This inversion eliminates interface problems between different materials while achieving the same mass placement objectives.
3Strength
If a removable weight system is used to maximize peripheral weight, then the moment of inertia is increased, but the attachment mechanism must securely prevent dislodgment during impact
Solution Approach 1:
The locking mechanism is designed to automatically engage and secure the weight member to the club head body upon insertion. The locking member and rollers预先 configure the attachment state, ensuring security before impact occurs without requiring additional action during use.
Solution Approach 2:
The cam surface on the locking member features curved geometry that converts linear insertion motion into rotational locking action. This curved surface guides the rollers into the locked position, creating a secure attachment that resists dislodgment during impact while maintaining smooth operation.

AI summary
A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.
