Solution Overview

Problem

Golf clubs are limited by volumetric, speed, and forgiveness constraints, particularly in adjusting the center of gravity (CG) for improved performance, necessitating an adjustable weight assembly for discretionary mass distribution.

Innovation Solution

A golf club head with an elongate channel featuring scalloped depressions and a weight member secured by a fastener, allowing adjustable positioning and secure fastening within the channel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed weight distribution is used in golf club head, then manufacturing is simple, but CG adjustability is limited

Engineering Contradiction:

ImproveCG adjustabilityVSAvoidweight assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The weight assembly is segmented into a weight member and a weight member receiver, allowing the weight member to be positioned at different locations within the receiver. This segmentation enables CG adjustability while keeping each component relatively simple in structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The weight assembly transitions from a fixed configuration to an adjustable one, where the weight member can be repositioned along the longitudinal axis of the weight member receiver. This dynamic capability allows golfers to adjust CG location based on performance needs.

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If weight member is made adjustable, then CG positioning precision is improved, but fastening reliability may be compromised

Engineering Contradiction:

ImproveCG positioning precisionVSAvoidfastening security

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

The fastening mechanism uses a cam surface and cam follower instead of traditional threaded fasteners. The cam surface converts rotational motion of the set screw into linear motion that pushes the weight member against the retention rail, providing both precise positioning and secure fastening.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cam surface is curved, allowing the set screw to engage the weight member at different positions along its longitudinal axis. This curvature enables precise CG positioning while the mechanical engagement ensures reliable fastening through the cam-follower interaction.

Inventive Principle:

Principle #14Spheroidality (Curvature)
