Head-Mounted Laser Training Aid for Golf Swing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers find it difficult to maintain a proper swing technique due to the lack of effective visual feedback on head movement during practice, leading to the development of bad habits, especially for novice golfers who cannot afford professional coaching.
Innovation Solution
A training aid mounted on headwear with two adjustable laser pointers that cross over a target, providing instantaneous visual feedback on head movement by shifting their endpoints when the golfer's head moves, allowing for improved awareness and correction of swing alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single light beam is used to guide the golfer, then the device is simple and easy to use, but it fails to detect certain head movements that do not change the beam's endpoint position
Solution Approach 1:
The single light beam is divided into multiple light beams (first light beam and second light beam) that originate from different positions on the headwear. This segmentation allows each beam to detect different types of head movements, thereby improving measurement precision while maintaining relative simplicity of the device.
Solution Approach 2:
The invention adds spatial dimensionality by positioning light sources at multiple locations (e.g., left and right sides of the head) rather than a single central position. This multi-dimensional arrangement creates multiple reference lines that can detect movements in different directions, improving the ability to detect head movements without significantly complicating the device.
2Device complexity
If parallel light beams are used, then the device structure is simple, but it cannot detect rotational head movements that maintain beam alignment with the target
Solution Approach 1:
Instead of using symmetric parallel beams, the invention employs asymmetric light beam arrangements where beams originate from different lateral positions on the headwear. This asymmetric configuration ensures that rotational movements of the head will cause at least one beam to deviate from its reference line, improving detection reliability while keeping the structure relatively simple.
Solution Approach 2:
The light beams are pre-positioned to create reference lines that bracket the target before the swing begins. This preliminary setup establishes a detection framework that automatically indicates head movement during the swing, improving reliability without requiring complex real-time adjustment mechanisms.
3Measurement precision
If multiple light beams from different positions are used to detect all head movements, then detection accuracy improves, but the device becomes more complex and harder to adjust
Solution Approach 1:
The light beam system is designed so that multiple beams serve dual purposes: they collectively detect various types of head movements (translation and rotation) while also providing a comprehensive visual reference framework for the golfer. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity.
Solution Approach 2:
The system uses the golfer's own head and body as the reference frame for the light beams. By positioning beams on the headwear and having them project relative to the golfer's natural stance and target, the system self-adjusts to different golfers without requiring complex calibration mechanisms, thus improving measurement precision while minimizing device complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The training aid enhances the golfer's ability to maintain proper head alignment and stance awareness, facilitating better swing technique through immediate visual feedback, making it easier for golfers to practice and correct their swing without the need for expensive coaching.
Implementation Method 1
The training aid comprises two laser pointer devices that are adjustably mounted on the headwear, one on each side of the head

AI summary
A training aid for practicing a golf swing. Two laser pointers are mounted at opposite ends of a bar that is affixed to a hat. The laser pointers are horizontally and vertically adjustable and are adjusted such that the laser beams from the two laser pointers cross at a desired point in front of the user. While maintaining the proper stance for a golf swing, the beams are adjusted to intersect each other a short distance above the golf ball. Any movement of the head will cause the beams to shift. This provides immediate feedback to the user and is useful in training the user to execute a golf swing while keeping the head in a certain position and motionless.
