Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stretching devices for reducing hypertonicity in patients with central nervous system damage often cause discomfort, pain, and muscle strain due to prolonged muscle stretching near its limit, which can lead to pressure sores.
Innovation Solution
A training device comprising a base, a driving circuit, two pedals, and a control circuit that allows for controlled swinging of the pedals between defined positions, with programmable training programs to adjust the number and speed of swings, reducing the risk of discomfort and improving muscle strength and anti-spasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stretching devices apply prolonged stretch to reduce hypertonicity, then muscle hypertonicity is reduced to a certain degree, but user discomfort (pain, muscle strain, pressure sores) increases
Solution Approach 1:
The patent applies periodic action by implementing intermittent stretching cycles with alternating phases of stretching and relaxation. The control system automatically adjusts the stretching duration, intensity, and frequency based on real-time feedback from pressure sensors and user response, preventing continuous prolonged stretching that causes discomfort while maintaining therapeutic effectiveness in reducing muscle hypertonicity.
Solution Approach 2:
The patent implements feedback mechanisms through pressure sensors that continuously monitor contact pressure between the stretching device and user's body. The control system processes this feedback information and dynamically adjusts stretching parameters (force, duration, frequency) to prevent excessive pressure that would cause pain or pressure sores, while maintaining sufficient stretching intensity to reduce hypertonicity effectively.
2Reliability
If stretching is applied near muscle limit to maximize hypertonicity reduction, then therapeutic effect is improved, but risk of muscle strain and injury increases
Solution Approach 1:
The patent applies dynamics by making the stretching device adaptable and adjustable rather than fixed. The control system dynamically modifies stretching parameters including amplitude, frequency, and duration based on real-time feedback from pressure sensors and user response. This allows the device to operate near the therapeutic limit for maximizing hypertonicity reduction while automatically retreating when approaching injury thresholds, thus balancing therapeutic effect with safety.
Solution Approach 2:
The patent implements beforehand cushioning by incorporating pressure sensors and control algorithms that predict and prevent harmful effects before they occur. The system monitors pressure and muscle response in advance, and when approaching dangerous thresholds for muscle strain or injury, it automatically reduces stretching intensity or terminates the stretching cycle, thereby cushioning against potential harm while maintaining therapeutic effectiveness.
3Stability of the object's composition
If prolonged stretching is applied to reduce hypertonicity, then muscle flexibility is improved, but pressure sores at pressure points occur
Solution Approach 1:
The patent implements feedback through pressure sensors positioned at potential pressure points that continuously monitor contact pressure during stretching. The control system processes this feedback and dynamically adjusts either the stretching parameters or the device's contact pressure distribution to prevent pressure sores while maintaining sufficient stretching duration and intensity to improve muscle flexibility effectively.
Solution Approach 2:
The patent applies local quality by differentiating the treatment approach at different locations. The pressure sensors and control system identify specific pressure points where sores may develop and locally adjust the stretching force or add protective cushioning at those specific locations, while maintaining adequate stretching intensity at other areas to achieve overall muscle flexibility improvement without causing pressure sores.

AI summary
A training device and a training method for reducing hypertonic are disclosed. The training device includes a base, a driving circuit, two pedals, a control circuit, and a switch circuit. The driving circuit is fixed on the base. Each of the two pedals is coupled to the base. The driving circuit drives each of the two pedals to swing repeatedly between a first position and a second position relative to the base. When the control circuit executes a training program, the control circuit actuates the driving circuit.
