Solution Overview
Problem
Existing breathing devices for training and medical use lack the ability to vary the frequency of air flow interruptions during operation, which can lead to user accommodation and reduced effectiveness in improving breathing efficiency.

A breathing device with a valve mechanism, such as a reed or oscillating valve system, that allows for random variation of air flow interruptions between 5 to 100 Hz, controlled by a mechanically or electrically driven valve, enabling strengthening of respiratory muscles through variable frequency training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed frequency valve mechanism is used in breathing devices, then the device structure is simple and easy to manufacture, but the breathing training effectiveness deteriorates due to user accommodation and reduced improvement
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a fixed-frequency valve mechanism to a variable-frequency mechanism that can randomly adjust its operating frequency during use. This dynamic adjustment prevents user accommodation and maintains training effectiveness by continuously adapting to the user's breathing patterns, thereby resolving the contradiction between training effectiveness and device complexity.
Solution Approach 2:
The patent implements parameter changes by randomly varying the frequency parameter of the valve mechanism during operation. This random frequency variation ensures that users cannot adapt to a fixed rhythm, thereby maintaining the effectiveness of breathing training while managing device complexity through controlled parameter adjustment rather than complex structural changes.
2Reliability
If the valve frequency is randomly varied during operation, then breathing training effectiveness is improved by preventing accommodation, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent applies dynamics by implementing a valve mechanism that can randomly adjust its frequency during operation rather than maintaining a fixed frequency. This dynamic capability prevents user accommodation and maintains training effectiveness. The control system achieves this through relatively simple frequency variation mechanisms rather than complex structural changes, balancing effectiveness improvement with acceptable device complexity.
3Strength
If a motor-driven rotary valve is used with variable frequency control, then respiratory muscle strengthening is enhanced through random frequency variation, but the device becomes more complex and expensive
Solution Approach 1:
The patent implements parameter changes by randomly varying the frequency parameter of the motor-driven rotary valve during operation. This frequency variation enhances respiratory muscle strengthening by exposing muscles to diverse frequency stimuli, preventing adaptation. The control system achieves this through software-based frequency modulation rather than complex hardware changes, thereby enhancing muscle strength while managing device complexity and cost.
Solution Approach 2:
The patent applies dynamics by making the valve frequency variable rather than fixed, allowing the system to adapt dynamically to training needs. This dynamic frequency adjustment maximizes respiratory muscle strengthening effectiveness. The motor control system achieves this through controlled frequency variation mechanisms that balance enhanced training effectiveness with acceptable device complexity and manufacturing costs.
