Golf Training Device Tactile Forearm Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf swing training devices face issues with cumbersome and expensive light source-based systems that are prone to breakage and require battery replacement, as well as mechanical attachments that are susceptible to damage and high costs, while also failing to provide effective feedback for proper swing alignment.
Innovation Solution
A golf training device featuring a cylindrical body with a flange section that attaches to the club grip, providing a tactile alignment angle through a disc-shaped edge that contacts the forearm, ensuring proper hand, wrist, and forearm alignment with the club shaft, and is designed to be lightweight, durable, and easy to use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If light source-based systems are used to provide visual indication of club position, then feedback to golfer is improved, but device reliability deteriorates due to breakage risk and battery replacement requirements
Solution Approach 1:
The patent removes the light source and battery components from the training device, extracting the problematic elements that caused reliability issues. Instead of using optical feedback, the invention employs a simple mechanical alignment guide that provides tactile and visual alignment reference without requiring power sources or fragile components.
Solution Approach 2:
The invention replaces expensive, maintenance-requiring light sources with a simple, inexpensive mechanical alignment guide made from durable materials. The device is designed to be robust and maintenance-free, eliminating batteries and fragile optical components that required replacement or careful handling.
2Ease of operation
If mechanical attachments are used to teach proper swing, then swing guidance is improved, but device complexity and susceptibility to damage increase
Solution Approach 1:
The patent extracts complex mechanical mechanisms from the training device, retaining only the essential alignment function. The solution uses a simple cylindrical body with a conical alignment surface that provides swing guidance through basic geometric reference, eliminating complicated mechanical linkages, joints, and adjustment mechanisms.
Solution Approach 2:
Instead of using complex mechanical attachments that move with the club, the invention inverts the approach by providing a static alignment reference that the golfer positions relative to their swing path. The alignment guide remains fixed on the training device while providing reference for the dynamic swing motion.
3Loss of information
If light sources are mounted in the golf club, then swing tracking is improved, but cost and maintenance requirements increase
Solution Approach 1:
The patent removes light sources and electronic components from the golf club training device, extracting the expensive and maintenance-requiring elements. The invention provides swing tracking functionality through simple mechanical alignment references that can be manufactured at low cost using conventional machining or molding processes.
Solution Approach 2:
The invention replaces electronic/optical swing tracking systems with a mechanical alignment reference system. The conical surface and cylindrical body provide geometric reference for swing plane without requiring sensors, light sources, or electronic processing, significantly reducing manufacturing cost and maintenance requirements.

AI summary
A golf training device comprising a body having a cylinder section including a first end and a second end opposite the first end. The cylinder section defines an interior portion extending from the first end to the second end. A flange section is coupled to the cylinder section proximate the second end. An edge is formed on a perimeter of the disc. A receiver is formed in the interior portion proximate the first end of the cylinder section. The receiver is configured to receive an end of a golf club grip. The interior portion is configured to contact the golf club grip in a fixed position. The edge portion configured to contact a forearm such that the forearm and a centerline of the golf club form an alignment angle. The alignment angle orients the golfers hands, wrist and forearms with a centerline of a golf club shaft.
