Golf Club Non-Metallic Connection Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf clubs require professional assistance for modifications, such as changing shafts or club heads, due to adhesive bonding, which is costly and time-consuming, limiting golfer flexibility in adjusting to physical changes or playing conditions.
Innovation Solution
A golf club assembly with a removable shaft and club head connection using a sleeve with external splines and an internally threaded opening, allowing for easy assembly and disassembly by the golfer, along with an adjustable loft system and sole piece for independent adjustment of loft and face angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive bonding is used to attach shaft to club head, then connection strength is improved, but ease of repair deteriorates
Solution Approach 1:
The connection assembly is divided into separate components: a hosel in the club head, a shaft with a receptacle, and a removable connector. This segmentation allows the shaft and club head to be easily separated and reconnected without damaging adhesive bonds, resolving the contradiction between connection strength and ease of repair.
Solution Approach 2:
A removable connector acts as an intermediary element between the shaft receptacle and the hosel. This mediator provides a mechanical connection that can be easily inserted and removed, maintaining connection integrity while enabling simple repair and modification by the consumer.
2Ease of repair
If mechanical fastener is used for removable connection, then ease of repair is improved, but device complexity deteriorates
Solution Approach 1:
The connection system is segmented into three main parts (hosel, shaft with receptacle, and connector), which simplifies the repair process by allowing easy separation and recombination of components without complex disassembly procedures.
Solution Approach 2:
The connector design integrates multiple functions: it provides mechanical attachment, prevents rotation through splines, and allows for easy removal and reattachment. This multi-functionality reduces the need for additional components, thereby managing device complexity while maintaining ease of repair.
3Reliability
If conventional adhesive bonding is used, then connection integrity is improved, but adaptability deteriorates
Solution Approach 1:
The connection assembly transitions from a static adhesive bond to a dynamic mechanical connection that can be easily adjusted, removed, and reconfigured. This allows golfers to adapt their clubs to changing physical conditions or playing requirements while maintaining reliable connections through the mechanical fastening system.
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
Enables golfers to customize their clubs without professional help, improving the golfing experience by allowing frequent adjustments to suit changing needs and conditions while maintaining the integrity and rigidity of conventional club head-shaft connections.
Implementation Method 1
The lower portion defines a longitudinally extending, internally threaded opening adapted to receive a screw for securing the shaft assembly to the club head
Implementation Method 2
The lower portion having eight, longitudinally extending, angularly spaced external splines located below the shaft and adapted to mate with complimentary splines in the hosel opening
