Solution Overview

Problem

Golfers often struggle to accurately aim their putts, leading to missed holes due to deviation from the desired path during the swing, as they focus on making contact with the ball rather than maintaining alignment with the hole.

Innovation Solution

An aiming key and putter design featuring a body with an aiming member and target, allowing golfers to align the aiming member with the hole and maintain focus on the target during the swing, enhancing alignment accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If golfers use a line etched in the putter to aim at the hole, then they can establish a desired line of sight, but the aiming accuracy is insufficient and the ball does not follow the desired path

Engineering Contradiction:
Improveaiming accuracyVSAvoidconsistency of following desired path
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The putter head is divided into functional zones: a first region with the face for striking the ball, and a second region with the aiming key featuring parallel sides and opening. This segmentation allows the aiming mechanism to be spatially separated from the striking mechanism, enabling independent optimization of each function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The aiming key acts as an intermediary tool between the golfer's aim and the putter face. The parallel sides and opening provide a reference framework that mediates the alignment process, allowing the golfer to establish the desired line of sight more accurately before executing the putt.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If golfers concentrate on making contact with the ball during putting, then they can execute the swing, but they move the putter off the desired path and miss the hole

Engineering Contradiction:
Improveability to execute swingVSAvoidalignment with desired path
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The aiming key enables preliminary alignment action before the swing execution. The golfer uses the parallel sides and opening to establish the desired line of sight and align the putter face with the target line before making contact with the ball, ensuring both proper alignment and successful execution.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The traditional mechanical alignment method (relying solely on the putter shaft and face) is replaced with an optical-mechanical system using the aiming key's opening and parallel sides as visual references. This substitution enhances the precision of alignment while maintaining the mechanical swing execution.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If golfers face the ball during putting, then they can focus on contact, but they cannot maintain alignment with the hole throughout the swing

Engineering Contradiction:
Improvefocus on ball contactVSAvoidvisual alignment with hole
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The aiming key serves as an intermediary that preserves visual alignment information. By providing the opening and parallel sides as reference markers, it allows the golfer to maintain awareness of the desired line while facing the ball, preventing loss of alignment information during the putting motion.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for enhancing the accuracy of aiming while putting a golf ball with a putter is provided. A head of the putter includes a body having top and bottom surfaces separated by a distance, an interior opening extending part of the distance from the top surface to the bottom surface, a first end and a second end. The second end includes a target and the first end includes an aiming member extending into the opening and towards a center of the target. The method includes the steps of focusing on a pointed end of the aiming member and aligning the pointed end with a hole in the ground, executing a backswing while concentrating on moving the pointed end of the aiming member towards the center of the target, executing a forward swing towards the golf ball, and striking the golf ball to translate the golf ball along the alinement towards the hole.
