Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf swing posture correction technologies are limited in their ability to effectively detect and correct the movement of the anchored leg during a golf swing, often requiring cumbersome equipment, analysis by personal computers, or are specific to head posture, making them difficult to use and transport for practical golfing.
Innovation Solution
A portable golf swing posture correction apparatus featuring a sensor unit to detect angular and vertical/horizontal movements of the anchored leg, a control unit to process signals, and a notification unit providing immediate feedback via sound or vibration, allowing the golfer to correct their posture efficiently on the golf course.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mat with swing detecting sensor is used to correct golf swing posture, then the trace of golf swing can be corrected, but the apparatus is difficult to carry on an actual golf course
Solution Approach 1:
The patent divides the golf swing detection system into separate wearable sensor units attached to specific body parts (head, shoulders, hips, knees, ankles) rather than using a single large mat-based system. This segmentation enables portable, distributed measurement that can be easily carried and worn on the golf course while maintaining detection capability.
Solution Approach 2:
The patent replaces the mechanical mat-based detection system with wearable sensors that use accelerometers and gyroscopes to detect body movement. This substitution eliminates the need for a physical mat while maintaining the ability to track and correct golf swing traces through digital signal processing.
2Measurement precision
If a system with sensors attached to various parts of the body is used to quantitatively analyze golf swing, then changes of the body in golf swing can be analyzed, but the system requires a personal computer for analysis causing inconveniences and is difficult to carry
Solution Approach 1:
The patent combines the sensor units, signal processing capabilities, and notification functions into an integrated portable system. The control unit processes signals from multiple sensors and generates feedback notifications, eliminating the need for external personal computers while maintaining comprehensive body movement analysis capability.
Solution Approach 2:
The wearable system performs self-contained signal processing and analysis through its control unit, which automatically processes sensor data and generates feedback without requiring external computer systems. This self-service capability enables the system to be portable and convenient for use on the golf course.
3Measurement precision
If an in-the-ear type system is used for head posture correction, then the head can be kept still, but the device requires minimization causing various restrictions and is costly to manufacture
Solution Approach 1:
The patent uses universal accelerometer and gyroscope sensors that can detect motion in multiple directions and are applicable to various body parts. These standard sensors replace specialized in-the-ear systems, reducing manufacturing costs while maintaining the ability to correct head posture and providing additional functionality for detecting movements of other body parts.

AI summary
A golf swing posture correction apparatus and method therefor are provided. Provided is the golf swing posture correction system apparatus capable of detecting movement of an anchored leg in a golf swing and notifying a user, thereby correcting a golf swing posture. The anchored leg is a left leg for a right-handed person and a right leg for a left-handed person. The golf swing posture correction apparatus detects the movement of the anchored leg, and processes a detected signal, thereby generating sound via a speaker or vibration.
