Swing Trainer Link Mechanism Inhibits Elbow Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf and other bat sports present challenges in mastering the club swing due to numerous variables, with beginners often struggling to maintain arm position and experiencing 'flying elbow' issues, which existing training aids have not effectively addressed.
Innovation Solution
A swing trainer with arm mounts and a flexible link system that connects to the club, allowing the arms to be drawn together during the backswing, inhibiting elbow separation and promoting a mechanically efficient swing by shortening the link between the arms as the club is cocked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a player attempts to maintain arm position during a golf swing, then swing accuracy is improved, but difficulty in controlling arm position increases due to multiple variables
Solution Approach 1:
The training device uses a link mechanism with arms that acts as an intermediary between the player's arms and the club. This mechanical intermediary guides and constrains arm movement, providing tactile feedback and physical guidance to maintain proper arm position throughout the swing, thereby simplifying the control complexity while improving position accuracy.
2Reliability
If existing training aids are used to address flying elbow, then some guidance is provided, but the difficulty of maintaining proper elbow position throughout the swing remains unresolved
Solution Approach 1:
The training device changes the physical parameters of the swing by introducing a link mechanism that mechanically constrains elbow separation. The link acts as a physical parameter controller, maintaining a predetermined distance between arm mounts, which reliably prevents flying elbow while guiding the player through proper swing mechanics.
3Stability of the object's composition
If the link between arms is shortened during backswing, then arm alignment is improved, but the mechanism complexity increases
Solution Approach 1:
The link mechanism is designed to be dynamic rather than static, allowing automatic adjustment of arm spacing throughout the swing. The link connects to arm mounts that move with the player's arms, dynamically maintaining proper alignment during backswing, downswing, and follow-through without requiring complex active control systems.

AI summary
A swing trainer configured to draw the elbows of the player together by the cocking of the player's wrists. The swing trainer includes arm mounts configured to mount to a player's arms at an intermediate position; and a link with at least a portion connected to the mounts and extending therebetween and arranged such that the portion of the link between the arms is configured to shorten during a swing of a stroke to inhibit splaying of the elbows of the player during the stroke, the link being slidably connected to the one of the mounts so it may slide past. A corresponding method of swing training using said swing trainer is also disclosed.
