Non-Concentric Actuator Exercise Device for Active-Passive Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise and rehabilitation devices provide only passive or superficial motions, lacking the interactive and comprehensive physical therapy benefits of both active and passive movements.
Innovation Solution
An interacting exercise device featuring a driving device with multiple shafts and a non-concentric actuator, where the unbalanced centrifugal force from a counterweight causes vibration, enabling both active user movement and passive body stimulation through a system of driving and driven wheels and a non-concentric actuator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If only passive motion training is provided through vibration platform, then users' bones and joints can be relieved from stiffness and tensions, but users don't move their bodies actively thus providing only superficial and limited effects on personal fitness
Solution Approach 1:
The patent combines active exercise functions with passive vibration therapy functions into a single integrated device. The user actively pedals the bicycle while the eccentric flywheel simultaneously provides passive vibration stimulation to the body, merging two previously separate functions into one comprehensive fitness solution
Solution Approach 2:
The exercise bicycle is designed to perform multiple functions: active cardiovascular exercise through pedaling, passive vibration therapy through the eccentric flywheel, and muscular stimulation through the unbalanced centrifugal force. This multi-functional design addresses various fitness needs in a single device
2Object-affected harmful factors
If vibration is generated through unbalanced centrifugal force from counter weight, then passive body stimulation is achieved, but device complexity increases due to non-concentric actuator mechanism
Solution Approach 1:
The patent employs an eccentric flywheel mechanism where the counterweight is positioned offset from the center of rotation. This dynamic arrangement creates unbalanced centrifugal force during rotation, generating vibration without requiring complex non-concentric actuator mechanisms. The simplicity of the eccentric design reduces structural complexity while achieving the desired passive stimulation effect
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 device provides a comprehensive exercise and physical therapy experience by combining active user movement with passive body vibration, enhancing muscle stimulation and joint mobility.
Implementation Method 1
Owing to unbalanced centrifugal force resulted from a counter weight arranged at the non-concentric actuator, the non-concentric actuator has a run-out that causes vibration

AI summary
An interacting exercise device is revealed. The interacting exercise device includes a driving device and a non-concentric actuator driven by the driving device. While the driving device is operated to rotate, the non-concentric actuator vibrates and the vibration generated is delivered to the interacting exercise device for interacting shaking fitness.
