Solution Overview

Problem

Existing putters have not optimized for easy interchangeability between striking surfaces while providing greater stability for high handicap golfers.

Innovation Solution

A putter-type club head design featuring a blade member with interchangeable face surfaces, a peripheral mass belt, a crown member, a sole member, and a dampening member, allowing for adjustable weight distribution and alignment aids, with components made from materials like aluminum alloys and stainless steel for enhanced stability and adjustability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a putter head uses fixed striking surfaces, then manufacturing is simpler, but interchangeability of faces is poor

Engineering Contradiction:

Improveinterchangeability of facesVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The putter head is divided into a blade member with multiple recesses and separate insert members that can be independently removed and repositioned. Each insert can be placed in different recesses to create different striking surfaces, enabling face interchangeability without redesigning the entire putter head structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The insert members are designed to be movable between different recesses in the blade member, allowing the golfer to dynamically change the striking surface configuration. This dynamic reconfiguration capability provides versatility while maintaining a relatively simple base structure.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If a putter head uses uniform mass distribution, then manufacturing is easier, but stability is reduced

Engineering Contradiction:

ImprovestabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The putter head employs non-uniform mass distribution through strategically placed inserts with different densities and positions. The blade member contains multiple recesses that can accommodate inserts of varying masses at specific locations, allowing local adjustment of weight distribution to optimize stability and moment of inertia without complicating the overall manufacturing process.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If a putter head uses single material construction, then manufacturing is simpler, but customization capability is limited

Engineering Contradiction:

Improvecustomization capabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The putter head utilizes composite construction by combining the blade member made from one material with separate insert members made from different materials. This allows the golfer to customize the club by selecting inserts with different material properties (such as density, hardness, or alignment characteristics) while the blade member provides a consistent structural base, achieving customization without requiring multiple complete putter head designs.

AI summary

A putter-type club head having a blade member and a peripheral mass belt is disclosed herein. The blade member is preferably composed of an aluminum alloy, and has a first surface with a first insert and a second surface with a second insert. The blade member is removably attached to the peripheral mass belt to allow for a reversal of the striking surface from the first face surface to the second face surface.
