Solution Overview

Problem

Golfers often struggle to accurately aim their putts, leading to missed shots due to deviation from the intended path during the putting stroke, despite using lines etched on their putters for alignment.

Innovation Solution

An aiming key and putter design featuring a body with parallel sides, an aiming member, and a target, along with an interior opening, which helps golfers focus on aligning the aiming member with the hole, enhancing the accuracy of their putting strokes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If golfers use lines etched on their putters for alignment, then they can establish a desired line of sight, but the alignment accuracy is insufficient leading to deviation from the intended path

Engineering Contradiction:
Improvealignment accuracyVSAvoidconsistency of putting path
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The putter head is divided into multiple functional components: a reference line for initial alignment, a rotation axis for adjusting the aiming key, and an aiming key with a target indicator for final precision alignment. This segmentation allows each component to perform a specific function in the alignment process, progressively improving accuracy from coarse to fine adjustment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The aiming key acts as an intermediary element between the golfer's line of sight and the hole. It provides a visual target indicator that mediates the alignment process, allowing the golfer to align with the indicator rather than directly with the hole, thereby improving alignment precision and consistency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If golfers concentrate on making contact with the golf ball, then they can execute the putting stroke, but the ball does not follow the desired path

Engineering Contradiction:
Improveease of executing putting strokeVSAvoidaccuracy of putting path
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The aiming key and target indicator provide preliminary alignment guidance before the putting stroke is executed. By establishing the correct path in advance through visual alignment with the indicator, the golfer can then focus on the mechanical execution of the stroke without worrying about directional accuracy, thereby maintaining ease of operation while improving path accuracy.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If the target is made to protrude into the opening, then visual alignment is enhanced, but the device complexity increases

Engineering Contradiction:
Improvevisual alignment precisionVSAvoidstructural complexity of aiming key
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The target indicator is nested within the aiming key structure, which itself is integrated into the putter head. This nested arrangement allows the target to protrude into the opening for enhanced visibility without requiring a separate, complex external mechanism. The compact nested design minimizes overall device complexity while achieving the visual enhancement goal.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

An aiming key for enhancing the accuracy of aiming while putting a golf ball is provided that includes a body having a pair of parallel sides. Each side has a first terminus and a second terminus and a first end extends between the first terminus of each side. Moreover, the body includes an arcuate second end extending between the second terminus of each side, a circular target proximate the second arcuate end, an interior opening including a first interior end and a second interior end. Furthermore, the body includes an aiming member aimed at a center of the target. The aiming member includes a first aiming member side, a second aiming member side, an aiming member end and an elongated cut-out intermediate the first and second aiming member sides. The cut-out and the aiming member sides are parallel to the parallel sides and the cut-out extends through the body.
