Swimming Trainer With Coupled Arm And Torso Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current non-aquatic swimming trainer devices are uncomfortable for extended use, do not simulate the motion or dynamic resistance experienced while swimming, and isolate arm and shoulder movement from torso and leg movement.
Innovation Solution
An exercise system that includes an arm movement system with handle guides and handles, and a torso movement system with a rotatable platform, designed to mimic the freestyle or front crawl stroke by providing resistive forces and coordinated movement of the arms and torso.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current non-aquatic swimming trainer devices are used, then arm and shoulder movement can be isolated for exercise, but the devices become uncomfortable after short sessions and do not simulate water resistance
Solution Approach 1:
The patent combines the arm movement system with a torso movement system into a single integrated exercise system. The handle guides are coupled to the rotatable platform such that arm movement drives torso rotation, simulating the coordinated motion experienced during swimming. This merging of systems maintains comfort for extended use while accurately simulating water resistance through the coupled mechanical systems.
2Ease of manufacture
If traditional swimming instruction in water is used, then proper stroke technique can be learned, but users face fear of drowning and health safety concerns
Solution Approach 1:
The exercise system creates a dry-land copy of the swimming experience. The handle guides and rotatable platform replicate the mechanical motion and resistance felt during water swimming, allowing users to practice stroke technique safely on land. This copying of the aquatic environment's mechanical effects enables users with health conditions or fear of water to learn swimming techniques without actual water exposure.
3Productivity
If current swimming devices isolate arm and shoulder movement, then focused exercise is achieved, but torso and leg movement coordination is not simulated
Solution Approach 1:
The patent merges isolated arm exercise with torso movement simulation into one integrated system. The handle guides are mechanically coupled to the rotatable platform, so that moving the handles produces both arm exercise and coordinated torso rotation. This maintains focused muscle building effectiveness while adding full-body coordination simulation capability.
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
The exercise system effectively simulates the resistive forces of water, allowing users to build muscle and practice proper form for the freestyle stroke without the complications of a water environment, enhancing comfort and effectiveness of training.
Implementation Method 1
each handle guide includes first and second handle guide cords and first and second handle guide springs. In some implementations, the first handle guide spring is coupled to one end of the first handle guide cord, and the second handle guide spring is coupled to one end of the second handle guide cord. In some implementations, the handle guide springs create a reaction force in response to movement of the respective handle along the handle guide cords
Implementation Method 2
the system further includes a first handle spring coupled to the first handle and a second handle spring coupled to the second handle. In some implementations, the first handle spring creates a reaction force in response to movement of the first handle in a direction that has a parallel component relative to the central axis of the first handle guide
Implementation Method 3
The rotatable platform is rotatable about the rotational axis thereof. The central axis of each handle guide is parallel to the rotational axis of the rotatable platform, and the rotatable platform is disposed adjacent the handle guides such that a user having the user's body supported by the rotatable platform can reach the handles with the user's hands
Implementation Method 4
the system further includes first and second handle damping springs. In some implementations, the first handle damping spring is coupled to and disposed between the first handle weight and the first handle, and the second handle damping spring is coupled to and disposed between the second handle weight and the second handle
