Golf Training Device Thigh-Mounted Resistance Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mastering a golf swing is challenging due to strength deficiencies and lack of coordination between muscle groups, particularly in the transverse plane of movement, which is not adequately addressed by conventional strength exercises.
Innovation Solution
A sport training device with an arcuate frame worn on the thigh, coupled with an elastic cord that provides resistance during the golf swing, reinforcing proper technique and muscle strengthening by increasing load on key muscle groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional strength exercises are used, then general muscle strength is improved, but transverse plane strength and golf swing coordination are not adequately addressed
Solution Approach 1:
The device uses a movable lever that rotates on a hinge to follow the natural arc of the golf swing, transforming static resistance into dynamic resistance that adapts to the movement plane. This allows conventional strength training to be adapted for transverse plane golf swing training.
Solution Approach 2:
The invention transitions training from the traditional sagittal plane to the transverse plane by positioning the lever horizontally in front of the user's body, creating resistance in the same dimensional plane as the golf swing motion.
2Strength
If resistance is provided during movement, then muscle strength is increased, but proper technique reinforcement may be compromised
Solution Approach 1:
The lever is pre-positioned in an extended horizontal location before the swing begins, and the elastic cord is pre-tensioned, so that resistance is automatically applied at the correct moment and angle throughout the swing arc, reinforcing proper technique while building strength.
Solution Approach 2:
The device provides immediate mechanical feedback through the lever and elastic cord system, which resists improper motion and guides correct swing mechanics, allowing users to self-correct technique while under load.
3Force
If the lever is extended horizontally in front of the body, then proper resistance angle is achieved, but device complexity increases
Solution Approach 1:
The lever mechanism serves multiple functions: it positions the elastic cord at the correct angle, provides a pivot point for rotational movement, and acts as a mechanical guide for the swing arc, reducing the need for additional complex positioning mechanisms.
Solution Approach 2:
The lever acts as an intermediary between the user's body movement and the elastic cord resistance, translating complex three-dimensional swing motion into effective linear resistance through its hinged rotation mechanism.

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 device enhances muscle strength and technique by providing adjustable resistance, improving posture and stabilization, and ensuring proper movement patterns, particularly beneficial for beginners and those struggling with controlling the golf club's inertia.
Implementation Method 1
an elastic cord is anchored to the lever... the elastic cord stretches, providing resistance against the movement

AI summary
The present invention provides a sport training device for improving technique by providing resistance within the context of a sporting movement. The invention comprises an arcuate frame worn on the thigh of a user, which is secure to the user's thigh with an adjustable belt or cuff coupled to the frame. A lever coupled to the frame extends away from the frame in front of the user's body and an elastic cord is anchored to the lever. An attachment means is coupled to the other end of the elastic cord to allow the user's arms to extend the cord, thereby providing resistance to the user's movement. The attachment means attaches the cord to a wrist strap or glove worn by the user or to the handle of a sport implement such as a golf club.
