Solution Overview

Problem

Golfers face difficulties in consistently hitting putts due to improper loft and lie angles of their putters, leading to inconsistent distance and direction, and aiming errors that can significantly affect the outcome of their shots.

Innovation Solution

A golf club fitting apparatus that includes angle indicators and a stroke-plane indicator to measure and adjust the effective loft, lie angle, and swing plane of a putter, ensuring optimal setup and alignment, comprising a first apparatus body with openings for receiving the shaft, angle indicators on the upper surface, and a collimated light source for precise aiming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a putter is used without special equipment to identify loft and lie angle, then the device complexity is reduced, but the measurement precision of effective loft and lie angle deteriorates

Engineering Contradiction:
Improvecomplexity of putter fitting equipmentVSAvoidprecision of loft and lie angle measurement
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The putter fitting apparatus is divided into separate functional modules: a shaft receiving module with first opening, a head receiving module with second opening, an effective loft indicator, and an effective lie angle indicator. Each module independently measures a specific parameter, allowing the system to provide comprehensive measurements without requiring a single complex integrated device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The apparatus introduces intermediary measurement indicators (effective loft indicator and effective lie angle indicator) that translate the complex geometric relationships of the putter into readable measurements. These indicators act as mediators between the putter's physical geometry and the golfer's understanding of proper fit parameters.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the putter effective loft and lie angle are not properly identified, then the ease of operation is improved (no adjustment needed), but the reliability of putting performance deteriorates

Engineering Contradiction:
Improveease of putter setupVSAvoidconsistency of putting performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The apparatus provides immediate visual feedback through the effective loft indicator and effective lie angle indicator, showing the golfer whether their putter is properly fitted. This feedback loop allows golfers to adjust their setup or equipment based on objective measurements, ensuring reliable putting performance without requiring expert intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The putter fitting apparatus is designed to be used by golfers themselves without requiring professional fitting equipment or expertise. The simple indicators and straightforward setup enable golfers to perform their own fitting, making the service accessible and easy to use while ensuring reliable results.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If multiple indicators (effective loft, effective lie angle, stroke plane) are included in the apparatus, then the measurement precision and comprehensiveness are improved, but the device complexity increases

Engineering Contradiction:
Improvecomprehensiveness of putter parameters measuredVSAvoidnumber of indicators and components in apparatus
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The apparatus combines multiple measurement functions (effective loft measurement, effective lie angle measurement, and stroke plane indication) into a single integrated device that attaches to the putter. By merging these functions into one unit, the system provides comprehensive measurements without requiring multiple separate tools or procedures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The putter fitting apparatus is designed as a multi-functional device that can measure and indicate multiple putter parameters simultaneously. The first opening receives the shaft while the second opening receives the head, allowing the single apparatus to perform multiple measurement functions that would otherwise require separate devices.

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

AI summary

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle and effective loft angle. The golf club fitting apparatus includes a lower surface that contacts a butt end of a grip, an upper surface opposite the lower surface, and a side surface connecting the upper and lower surfaces. An angle indicator is disposed at a predetermined angle relative to a shaft axis of the golf club so as to rest in a neutral position when the golf club is in a normal address position.
