Golf Club Screw With Compressible Head For Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club screws tend to loosen or 'back out' due to vibrations during use, leading to potential disengagement from the golf club head, as they are not securely retained within weight ports or receptacles.
Innovation Solution
A golf club screw design featuring a head with a compressible portion and a threaded engagement mechanism, including tapered extensions and a keyed bore insert made of a denser material like tungsten alloy, which provides spring tension when engaged, ensuring secure retention within a conical receptacle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional screw design is used, then the screw can be easily installed and removed, but the screw tends to loosen or back out due to vibrations during use
Solution Approach 1:
The screw head incorporates a compressible portion that dynamically adapts to the conical receptacle, creating spring tension that maintains secure retention during vibration while allowing for controlled installation and removal through threaded engagement
Solution Approach 2:
The compressible portion changes its physical state from uncompressed to compressed as it engages with the conical receptacle, transforming mechanical energy into elastic potential energy that provides continuous retention force against loosening
2Reliability
If the screw is securely retained within the receptacle, then the screw prevents disengagement during use, but the screw becomes difficult to remove for weight adjustment
Solution Approach 1:
The screw is divided into distinct functional segments: a compressible head portion for secure retention and a threaded engagement portion for controlled installation and removal, allowing the screw to simultaneously achieve strong retention and ease of adjustment
Solution Approach 2:
The threaded engagement portion acts as an intermediary mechanism that translates rotational motion into linear motion, providing controlled engagement and disengagement while the compressible portion maintains constant retention pressure
3Ease of manufacture
If a unitary weight design is used, then the manufacturing process is simplified, but the weight distribution cannot be adjusted
Solution Approach 1:
The weight system is segmented into removable screw components that can be independently manufactured and then assembled into the club head, enabling both simplified manufacturing of individual parts and flexible weight distribution adjustment through component selection and 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
The screw remains securely engaged with the golf club head during use, preventing disengagement while allowing for adjustable weight distribution without being permanently fixed.
Implementation Method 1
provides spring tension when engaged
Implementation Method 2
the second taper slope compresses the compressible feature when the screw is fully engaged with the receptacle
Implementation Method 3
The screw may further comprise a keyed bore insert, and the head of the screw may comprise a recess sized to receive the keyed bore insert. In some embodiments, each of the plurality of extensions may comprise an exterior surface, which may comprise a first taper slope. In other embodiments, the golf club head may further comprise a keyed bore insert, and the head of the screw may comprise a recess sized to receive the keyed bore insert. In some embodiments, the keyed bore insert may be composed of a first material, the screw may be composed of a second material, and the first material may be different from the second material. In another embodiment, the second material may have a higher density than the first material

AI summary
A screw for use with a golf club head is disclosed herein. The screw comprises a head portion with a compressible feature that more securely retains the screw within a receptacle in the golf club head. The compressible feature preferably is a plurality of tapered extensions that can be compressed inwards by a tapered portion of the receptacle, creating spring tension between the head of the screw and the tapered portion of the receptacle. This helps to prevent the screw from becoming dislodged from the golf club head when it is in use.
