Solution Overview

Problem

Existing adjustable weighting mechanisms in golf club heads consume significant discretionary mass, interfere with sound, and complicate the swing due to structural complexities, particularly with monolithic metal pieces.

Innovation Solution

A golf club head design featuring a channel with adjustable weight assembly using a screw, wedges, and a nut component that converts downward force into a side force to lock the weight within the channel, minimizing mass usage and structural interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If movable or slidable weights are used for adjustable weighting, then weight adjustability is improved, but device complexity increases due to monolithic metal pieces and support structures

Engineering Contradiction:
Improveweight adjustabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The weight assembly is divided into separate components: a weight body, a screw mechanism, and wedge elements. This segmentation allows each component to perform its specific function independently, reducing overall structural complexity while maintaining adjustability. The weight body can be separately optimized for mass properties, while the screw and wedges provide the adjustment mechanism without requiring a monolithic complex structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wedge elements act as intermediaries between the screw mechanism and the weight body. When the screw is rotated, it pushes the wedges which in turn move the weight body along the channel. This intermediary mechanism simplifies the overall structure by using simple geometric shapes (wedges) to transmit force rather than requiring complex guidance structures or monolithic integrated designs.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If support structures (ribs, support struts) are added to support weight positions, then weight positioning stability is improved, but discretionary mass is reduced

Engineering Contradiction:
Improveweight positioning stabilityVSAvoiddiscretionary mass
Core Design Contradiction:
Stability of the object's compositionVSWeight of stationary object

Solution Approach 1:

The weight assembly is designed to be self-contained with all necessary support features integrated into the weight body and channel structure itself. The channel provides inherent guidance and positioning without requiring additional external ribs or support struts. The weight body's geometry and the channel's shape work together to stabilize the weight position through the natural interaction of these two components, eliminating the need for separate support structures that would consume discretionary mass.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The support functions are merged into the existing channel and weight body structures rather than being added as separate components. The channel's geometry inherently provides positioning stability, and the weight body's shape integrates with the channel to maintain the weight in its adjusted position. This merging eliminates the need for additional ribs or support struts that would reduce discretionary mass.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If additional structural support is added for weight adjustment mechanisms, then adjustment reliability is improved, but acoustic performance deteriorates

Engineering Contradiction:
Improveadjustment reliabilityVSAvoidacoustic interference
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The adjustment mechanism is extracted from the monolithic metal piece approach and separated into distinct components (screw, wedges, weight body) that can be independently optimized. This extraction allows the use of simpler, less acoustically intrusive components while maintaining adjustment reliability. The wedge-based mechanism provides reliable adjustment without requiring large monolithic structures that would interfere with sound.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanism transitions from a monolithic metal piece design to a multi-component design using simpler geometric elements (screw threads, wedge angles). This parameter change in the mechanism's physical characteristics reduces acoustic interference while maintaining reliability. The simpler geometry of the screw and wedges produces less acoustic disturbance compared to complex monolithic structures.

Inventive Principle:
Principle #35Parameter changes
