Dual-Hand Training Device with Coupled Rotating Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional training devices primarily focus on arm muscle training, limiting the range of motion and failing to effectively engage the entire musculoskeletal system, including the torso and other muscle groups, thereby offering a limited and unvaried workout experience.
Innovation Solution
A dual-hand operated training device with two independent rotating devices, each with a handle, that can be actuated differently, and are rotationally coupled through gear wheels or a toothed belt, allowing for synchronized or asynchronous operation, enabling a wide range of movements that stress both arm and torso muscles, and can be adjusted for various directions and planes of rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single rotating mechanism is used for training, then the device structure is simple, but the range of motion and muscle engagement is limited
Solution Approach 1:
The training device is divided into two independent rotating mechanisms, each with its own handle and resistance device. This segmentation allows each mechanism to operate independently, providing varied ranges of motion and engaging different muscle groups, thereby resolving the contradiction between simplicity and versatility.
Solution Approach 2:
Each rotating mechanism is designed to perform multiple functions: training arm muscles, engaging torso muscles through synchronized or asynchronous operation, and providing varied ranges of motion. This multi-functionality increases adaptability without requiring entirely separate devices for each training goal.
2Adaptability or versatility
If conventional training devices are used, then the device structure is simple, but the strain on muscles is unvaried
Solution Approach 1:
The device incorporates two rotating mechanisms that can operate dynamically in different modes: synchronously to engage torso muscles, asynchronously to focus on arm muscles, or independently to provide varied strain patterns. This dynamic operation capability increases muscle strain variety while maintaining a relatively simple overall structure.
Solution Approach 2:
Each rotating mechanism has its own resistance device that can be independently adjusted to provide different levels of strain on specific muscle groups. This local quality adjustment allows for varied muscle strain without requiring complex overall device modifications.
3Adaptability or versatility
If both hands operate the same rotating mechanism, then the device structure is simple, but the operating possibilities are limited
Solution Approach 1:
The device segments the rotating mechanism into two independent units, each operable by one hand. This segmentation enables independent operation of each mechanism, allowing for synchronized or asynchronous hand movements and significantly increasing operating possibilities while maintaining structural simplicity through modular design.

AI summary
A training or gymnastic device (10) can be operated by a user by a rotating motion with both hands. For this purpose, a first rotating mechanism (11) and a second rotating mechanism (13) are provided. Each of the first and second rotating mechanisms has a handle (21, 23) for the user to grasp and rotate. The first and second rotating mechanisms each interact with a rotational resistance device (15) and are rotationally coupled to each other.
