Doorway Putt Trainer With Rollers for Single-Plane Stroke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Amateur golfers often adopt improper putting strokes with horizontal shoulder motion and misalignment between shoulders and feet, necessitating a training aid that promotes vertical shoulder rotation and proper alignment.
Innovation Solution
A putt training aid utilizing a back bar with adjustable rollers and support arms that fits within a doorway, ensuring the golfer's shoulders move vertically and maintain alignment during the putting stroke, optionally with a wearable harness for support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a golfer uses a traditional putting stroke without training aid, then the golfer has freedom of motion, but the golfer develops improper form with horizontal shoulder motion and misalignment
Solution Approach 1:
The training aid is divided into separate components: a back bar with rollers, support arms, and a base. These segments can be easily assembled and disassembled in a doorway without complex tools or setup procedures, resolving the contradiction between providing reliable form correction and maintaining ease of operation.
Solution Approach 2:
The rollers act as an intermediary mechanism between the golfer's shoulders and the doorway frame. They provide physical guidance to enforce vertical shoulder motion while remaining simple to install and remove, achieving reliable form correction without complex setup.
2Adaptability or versatility
If a training aid is designed to be portable and collapsible, then storage and transport are easy, but structural stability during use may be compromised
Solution Approach 1:
The device is segmented into modular components that can be collapsed and stored compactly when not in use. During use, the segments assemble into a stable configuration where the back bar is supported by the doorway frame and the base, achieving both portability and structural stability.
Solution Approach 2:
The back bar extends partially into the doorway space and is supported by the rollers contacting the door frame. This partial extension provides sufficient structural stability for training while maintaining the ability to collapse and store the device compactly when not in use.
3Adaptability or versatility
If the back bar is made adjustable to fit different golfers, then adaptability improves, but device complexity increases
Solution Approach 1:
The back bar is segmented into telescoping sections that can be adjusted to different lengths. These segments connect with simple locking mechanisms that allow easy adjustment for different golfer heights without adding significant complexity to the overall device structure.
Solution Approach 2:
The adjustable back bar design allows a single device to serve multiple golfers of different heights. The same adjustment mechanism provides both length adjustment and secure locking, achieving universality without proportionally increasing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates proper putting form by forcing vertical shoulder motion and alignment, is easy to set up, and collapsible for storage and transport.
Implementation Method 1
Two opposing rollers each extend away from one of the two opposing ends of the back bar. Each roller comprises an outer rolling surface and an inner stationary member. The outer rolling surface is free to rotate about a longitudinal axis of the roller.

AI summary
A putt training aid for use by a golfer in a doorway includes a back bar having two opposing ends and at least two arm receiving apertures therethrough. Two rollers each extend away from one of the two opposing ends of the back bar. Two support arms each include a proximal end fixable with one of the arm receiving apertures of the back bar, and a distal end that is preferably curved upwardly to engage the golfer under his arms. In use, with each support arm fixed under one of the arms of the golfer, and with the back bar positioned across a back of the golfer, the golfer stands in a putting position in the doorway with the rollers each contacting one of the sides of the doorway to maintain a putter in a single plane during a putting stroke.
