Vertical Swim Trainer Balance Platform and Eddy Current Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming exercise training apparatuses fail to combine efficient arm movement along a longitudinal axis with strengthening of the core muscles, leading to wasted energy and reduced swimming speed due to improper arm and torso alignment.
Innovation Solution
A vertical swim trainer with a balance platform and pulley system that requires users to maintain a rigid, aligned position, utilizing core muscles by adjusting the balance platform's stability and incorporating a loading mechanism with eddy current resistance to ensure optimal hand position and motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional swimming training apparatuses are used, then arm strength can be developed, but core muscle strengthening and body alignment control are not achieved
Solution Approach 1:
The device merges arm pulling exercise with core muscle engagement by requiring the swimmer to maintain an upright position on an unstable support structure while performing the pulling motion, thereby simultaneously developing both arm strength and core stability
Solution Approach 2:
The apparatus serves multiple functions: it provides arm strength training through resistance, core muscle strengthening through balance requirements, and body alignment control through the upright positioning mechanism, making it a multi-functional training device
2Ease of operation
If arm movement is not along the longitudinal axis, then ease of movement is improved, but energy efficiency and propulsion are reduced
Solution Approach 1:
The device incorporates feedback mechanisms including visual alignment indicators and the inherent feedback of maintaining balance on an unstable platform, which guide the swimmer to maintain proper longitudinal arm movement alignment while providing natural correction for energy-efficient positioning
3Ease of operation
If the balance platform is highly stable, then ease of operation is improved, but core muscle strengthening is reduced
Solution Approach 1:
The balance platform transitions from a static stable surface to a dynamic unstable surface that requires continuous active adjustment by the swimmer's core muscles, transforming the platform from a passive support to an active training element that strengthens core musculature
4Ease of operation
If the body is allowed to flex and bend during pulling, then ease of movement is improved, but speed and penetration are reduced
Solution Approach 1:
The device applies preliminary anti-action by creating an unstable support condition that preemptively counteracts unwanted body flexing and bending during the pulling motion, forcing the swimmer to maintain rigid body alignment before the harmful movement can occur

AI summary
A swim trainer comprising: a base; an upright member extending from the base; two arms each carried by the upright member and terminating with an end pulley; two pull cords each having one end connected to a hand pull, extending from the hand pull over the end pulley, a second pulley positioned adjacent to the upright member, and then along the upright member; a rotatable shaft positioned adjacent to the base; a loading mechanism, connected to the shaft, to resist rotation and unwinding of the cord around the shaft; a clutch assembly positioned on the shaft arranged to rotate the shaft when the handle is pulled down and otherwise spin freely; a rewind bias means to rewind the cord around the shaft; and, a tipping and/or rotating balance platform assembly, seated on the base, for the swimmer to stand on, when pulling the hand pull.
