Semicircular Core Trainer with Resistance for Golf Swing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf training methods often prioritize hand and arm dominance over core rotation, which can diminish club head speed and mechanics in a golf swing, as the natural physiological hand dominance in humans hinders the development of a biomechanically advantageous swing.
Innovation Solution
A training device designed to increase rotary power and muscle memory of the core structures by using a semicircular apparatus with a resistance member, such as an elastic tether or pulley/weight system, that allows the user to rotate their shoulders and hips while keeping their hands and arms passive, focusing on core rotation as the primary source of club head speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand and arm dominance is prioritized in golf training, then complex motor activities and control are improved, but core rotation power and club head speed are diminished
Solution Approach 1:
The training device inverts the traditional golf training approach by making the hands passive and the core active. The semicircular apparatus with resistance member forces the user to generate power through core rotation rather than hand dominance, reversing the natural physiological tendency and creating the desired biomechanical swing pattern
Solution Approach 2:
The semicircular apparatus with resistance member serves as an intermediary training tool that mediates between the user's natural hand-dominant tendency and the desired core-dominant swing. The resistance member provides feedback that guides the user to rotate the core rather than use hand strength, acting as a mediator to transfer the motion pattern
2Power
If hands are kept passive during training, then core rotation is emphasized, but hand synchronization with body rotation must be precisely controlled
Solution Approach 1:
The training device uses preliminary action by having the user grip the handles and position themselves on the semicircular apparatus before the actual rotational training begins. This preliminary positioning ensures that when the user rotates, their hands are already correctly positioned to follow the core rotation naturally, reducing the complexity of synchronization control

AI summary
A core training apparatus for the golf swing. A semicircular member is coupled with a support member, and a resistance member is connected to one of the coupling points. The resistance member is secured to a fixed point, and the user rotates the apparatus back and forth with the user standing at the center rotational axis of the semicircular member, with the resistance member being guided along the semicircular member. The back-and-forth rotation acts to increase and decrease tension on the resistance member thereby exercising the core of the user.
