Golf Hip-Turn Link Stick with Elastic Retainers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beginner golfers face challenges in correctly timing their hip-turn movement in relation to the upper body's swing, leading to inconsistent swing planes and reduced power, often requiring costly professional instruction to correct.
Innovation Solution
A golf hip-turn timing practice device featuring a fastening belt with retainers and a hip-turn link stick equipped with LEDs and acceleration sensors, providing immediate feedback on incorrect timing by interfering with the swing when the hip-turn is premature, thus guiding the user to correct their timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If golfers hire professional instructors to correct their swings, then swing timing and technique are improved, but training costs and time investment increase
Solution Approach 1:
The device enables golfers to self-diagnose and self-correct their hip-turn timing issues without requiring professional instructors. The visual feedback mechanism allows users to independently identify timing errors and make adjustments, eliminating the need for expensive and time-consuming professional lessons.
Solution Approach 2:
The device provides immediate visual feedback through the link stick's position relative to the target object, allowing golfers to real-time monitor and adjust their hip-turn timing. This continuous feedback loop enables rapid correction of swing timing errors without external instruction.
2Measurement precision
If golfers practice at driving ranges, then swing technique can be improved, but travel time and practice costs increase
Solution Approach 1:
The device transforms the practice process into a self-service activity that can be performed anywhere without requiring access to specialized facilities like driving ranges. Golfers can practice and receive feedback in their own backyard or any open space, eliminating travel requirements.
Solution Approach 2:
The device serves multiple functions: it provides timing feedback, visual alignment guidance, and technique correction all in one portable unit. This multi-functionality replaces the need for specialized driving range facilities while maintaining comprehensive practice capabilities.
3Ease of operation
If the hip-turn link stick is positioned lower on the waist, then it is easier to wear, but the stick bends and fails to provide accurate timing guidance
Solution Approach 1:
The device changes the positional parameter of the retainers from lower waist placement to upper waist placement. This parameter change ensures the link stick remains straight and provides accurate timing guidance while still maintaining ease of wear through the elastic fiber construction and adjustable retainer positions.
Solution Approach 2:
The elastic fiber sheets are strategically positioned at the upper waist area where they provide the necessary structural support to keep the link stick straight, while the overall device remains comfortable to wear. The local quality of the retainer placement optimizes both reliability and comfort.
4Device complexity
If the second fitting passages are positioned at the same level as the first fitting passage, then the structure is simpler, but the hip-turn link stick bends when worn on the waist
Solution Approach 1:
The device changes the vertical position parameter of the second fitting passages relative to the first fitting passage. This parameter adjustment compensates for the curvature of the waist when wearing the device, ensuring the link stick remains straight without requiring complex structural modifications to the retainers.

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 self-practice for golfers to achieve proper swing timing and plane alignment, enhancing power transfer and reducing the need for expensive lessons by providing immediate feedback on incorrect hip-turn timing.
Implementation Method 1
the first retainer and the second retainer are elastic fiber sheets, and the second fitting passages of the second retainer are positioned higher than the first fitting passage of the first retainer such that the hip-turn link stick is maintained straight without bending with the fastening belt on a waist
Implementation Method 2
a hip-turn link stick equipped with LEDs and acceleration sensors, providing immediate feedback on incorrect timing
Implementation Method 3
A hip-turn link stick equipped with LEDs and acceleration sensors, providing immediate feedback on incorrect timing

AI summary
A golf hip-turn timing practice device according to the present disclosure includes: a fastening belt; a first retainer; a plurality of second retainers; and a hip-turn link stick that is fitted in the first retainer and the second retainers in the longitudinal direction of the fastening belt to be fixed at the position and is longer than the width of shoulders. The golf hip-turn timing practice device provides an advantage in that the golf hip-turn timing practice device enables correct swing timing practice by timing a hip-turn, which is a movement of a lower body, with the movements of the arms and hands of the upper body in golf swing. Further, the golf hip-turn timing practice device provides immediate feedback when the timing is wrong, is easily worn on the waist, and corrects a wrong swing by accurately showing the plane by hip-turn.
