Golf Club Light Indicator for Accurate Club Face Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf clubs with center lines on the club head make it difficult for users to align the club face with the target direction due to the line appearing curved when viewed from a diagonal angle, complicating the alignment process.
Innovation Solution
A method and system using first and second light beams to create a straight-line indicator on the club head, where the first beam is drawn on the floor in the club face direction and the second beam is projected onto the club head, allowing the user to align the club face with the target direction intuitively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a center line is imprinted on the club head to indicate the club face direction, then the indicator is visible on the club head, but the line appears curved when viewed from a diagonal direction, making it difficult to align with the target direction
Solution Approach 1:
The patent introduces a floor surface as an intermediary medium to receive the first light beam, which defines the target direction. This mediator allows the user to align the club face with the target direction by referencing the light beam on the floor rather than relying on a curved indicator on the club head, thereby resolving the alignment accuracy issue while maintaining indicator visibility
Solution Approach 2:
The patent transitions the alignment reference from a two-dimensional curved line on the club head surface to a one-dimensional straight light beam projection on the floor surface. This dimensional change allows the indicator to appear straight when viewed from the user's diagonal perspective, eliminating the curvature distortion while preserving visibility on the club head
2Ease of operation
If a straight line indicator is created on the club head, then alignment with target direction becomes easier, but the indicator may not follow the curved surface of the club head, reducing visibility or accuracy
Solution Approach 1:
The floor surface serves as an intermediary that receives the light beam projection, allowing a straight line indicator to be created in three-dimensional space without being constrained by the curved surface of the club head. This enables the indicator to remain straight for easy alignment while the club head's curved surface is accommodated through the spatial projection method
Solution Approach 2:
The patent replaces the mechanical approach of physically imprinting a straight line on the curved club head surface with an optical system that projects a light beam in three-dimensional space. This substitution allows the creation of a perfect straight line indicator that is not limited by the club head's geometry, improving alignment ease while avoiding manufacturing challenges
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to easily align the club face with the desired direction by following the straight-line indicator, maintaining consistent club head attitude and intuitively checking alignment, regardless of the club's curved or bent surface.
Implementation Method 1
a first light beam extending in a direction in which a club face is facing is drawn on a floor surface by light that is emitted from a first light source
Implementation Method 2
a second light beam that is either parallel with the first light beam or is superimposed thereon is drawn on the club head by light that is emitted from a second light source

AI summary
An indicator creation method enables a user holding a golf club in preparation to swing the club to create an indicator that makes it easy to aim a club face. In this method, a first light beam extending in a direction in which a club face is aimed is drawn on a floor surface by light emitted from a first light source mounted on the club, and the user holds the club in preparation to swing the club in such a way that the first light beam faces in a predetermined direction, a second light beam that is either parallel with the first light beam or superimposed thereon is drawn on the club head by light emitted from a second light source disposed in front of a head portion of the user, and an indicator is created on the club head based on the second light beam.
