Dual-Grip Upper Limb Training Device with Spinning Mass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wrist exercisers are designed for single-hand operation, limiting their ability to effectively train multiple body parts and both upper limbs simultaneously, with training benefits primarily focused on the wrist rather than the arms and shoulders.
Innovation Solution
The upper limbs training device features a housing with two grip portions and a spinning mass, allowing simultaneous training of both upper limbs by rotating the device with both hands, incorporating a sleeve ring, annular rail, and a driving assembly to generate centrifugal and inertial forces for comprehensive muscle engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wrist exerciser is designed for single-hand operation, then the structure is simple, but the training coverage is limited to one wrist at a time
Solution Approach 1:
The housing is divided into a first housing and a second housing that are symmetrically disposed, with each housing having its own grip portion. This segmentation allows independent operation of each side while maintaining overall structural simplicity through modular design.
Solution Approach 2:
The first and second housings are combined into a single integrated device with a shared spinning mass and driving assembly. This merging enables simultaneous training of both wrists while avoiding the complexity of two separate devices, as the core mechanical components are shared.
2Productivity
If the wrist exerciser is operated alternately with right and left hands, then the device structure remains simple, but the training efficiency is reduced
Solution Approach 1:
The device enables dynamic simultaneous operation by providing two independent grip portions that can be operated at the same time. The symmetric design allows both hands to apply force concurrently to the spinning mass, doubling the training efficiency compared to alternating operation.
3Adaptability or versatility
If the wrist exerciser focuses training on the wrist, then the device design is simple, but the training scope is limited
Solution Approach 1:
The device is designed to provide multi-functional training by enabling simultaneous engagement of wrists, arms, and shoulders through the two grip portions. The universal design allows the same device to train multiple muscle groups without requiring additional components or mechanisms.

AI summary
An upper limbs training device includes a housing, a sleeve ring, and a spinning mass. The housing includes two casings and an annular rail. The casings surround a space. The annular rail is fixed in the space. The sleeve ring is rotatably disposed on the annular rail. The spinning mass includes two shaft portions located at a first and second insertion hole portion of the sleeve ring. Each casing includes a first, second and third protrusion portion. In each casing, the first protrusion portion is located between the second and third protrusion portion. Two recesses are respectively formed between the first and second protrusion portion and between the first and third protrusion portion. The first protrusion portions form a base portion. The annular rail is mounted on the base portion. The second protrusion portions form a first grip portion. The third protrusion portions form a second grip portion.
