Solution Overview

Problem

Existing golf putters lack a design that combines offset shaft attachment with alignment aids, leading to distractions for golfers during putting, as alignment features can shift focus away from the ball.

Innovation Solution

A golf putter design featuring a tube coupled to the club head at an angle, with a coupling member connecting the tube and shaft, providing offset and blocking alignment indicia from view when properly aligned, thus focusing the golfer's attention on the ball.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If alignment indicia are provided on the club head to help with putting alignment, then the golfer can achieve proper alignment more easily, but the alignment indicia become distracting and shift the golfer's focus away from the golf ball

Engineering Contradiction:
Improvealignment capabilityVSAvoiddistraction from ball
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The alignment indicia are extracted from the main viewing area and relocated to the heel side of the club head where they are positioned to be blocked by the tube. This allows the alignment function to be preserved while removing the distracting visual element from the golfer's primary focus area.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The tube serves as an intermediary element that blocks the alignment indicia from the golfer's view when the club is properly aligned. This mediator allows the alignment indicia to remain on the club head for alignment purposes while preventing them from becoming distractions during the putting stroke.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the tube is coupled to the head at an angle to block alignment indicia, then the golfer's focus remains on the ball, but the structural complexity of the shaft attachment increases

Engineering Contradiction:
Improvedistraction eliminationVSAvoidshaft attachment structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shaft attachment is segmented into multiple components: a tube coupled to the club head at an angle, a coupling member connecting the tube and shaft, and the shaft itself. This segmentation allows each component to perform its specific function while managing the overall structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tube serves multiple functions: it provides structural support for the offset shaft attachment, blocks the alignment indicia from view when properly aligned, and contributes to the club's moment of inertia. This multi-functionality reduces the need for additional components, managing complexity while achieving multiple objectives.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If offset is provided by extending the shaft forward of the hosel, then the golfer achieves a desired putting posture with hands forward of the club head, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveputting postureVSAvoidoffset alignment
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The offset structure is segmented into the tube (coupled to the head at an angle), the coupling member (providing the offset connection), and the shaft. This segmentation allows for modular manufacturing and assembly, reducing the precision requirements compared to creating a single integrated offset hosel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling member acts as an intermediary that provides the offset connection between the tube and shaft. This separate coupling component allows for easier manufacturing and assembly while maintaining the desired offset geometry, reducing the overall manufacturing precision requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A golf putter with a novel offset and shaft-attachment design is disclosed and claimed. The club includes a head having a strike surface, a sole, and a top line. A tube is coupled to the head, a coupling member is coupled to the distal end of the tube, and a shaft is also coupled to the coupling member. The coupling member connects the tube and the shaft such that they are relatively offset. The longitudinal axes of the tube and the shaft may be substantially parallel, or the coupling member may be adjustable such that the longitudinal axes are not parallel. An alignment indicia is provided on the club head. The tube is coupled to the head at an angle such that it blocks the indicia from a user's view at address when the head is aligned properly. If the club head is not properly aligned, the golfer will be able to see the indicia and therefore know to adjust the club head before putting. Thus, putter disclosed and claimed herein provides both offset and a putting alignment aide.
