Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electrical stimulation approaches are used, then the stimulation protocol is simple and fixed, but the system cannot adapt to the subject's condition resulting in overstimulation or understimulation
Solution Approach 1:
The patent implements a closed-loop feedback system where sensor electrodes detect physiological signals (EMG, ECG, respiration) from the subject, and this feedback is used to dynamically adjust stimulation parameters. The processor continuously monitors sensor signals and modifies stimulator output in real-time based on the subject's condition, enabling adaptive stimulation that prevents overstimulation or understimulation.
Solution Approach 2:
The system transitions from a static, fixed stimulation protocol to a dynamic, adjustable protocol. Stimulation parameters such as intensity, frequency, and duration are made variable and can be adjusted in real-time based on feedback from sensor electrodes, allowing the system to adapt to changing subject conditions during treatment.
2Manufacturing precision
If fixed stimulation protocol is used, then the device complexity is low, but the control precision over micturition or bowel movements is inadequate
Solution Approach 1:
Sensor electrodes detect physiological signals (EMG, ECG, respiration) from the subject, and this feedback is used to dynamically adjust stimulation parameters. The processor continuously monitors sensor signals and modifies stimulator output in real-time based on the subject's condition, enabling adaptive stimulation that prevents overstimulation or understimulation.
Solution Approach 2:
The system dynamically changes stimulation parameters (intensity, frequency, pulse width) based on detected physiological conditions. Different parameter sets can be applied depending on the subject's real-time state, allowing precise control adjustment to achieve optimal stimulation effect.
3Reliability
If electrical stimulation is increased to ensure adequate control, then control effectiveness improves, but the risk of overstimulation and discomfort increases
Solution Approach 1:
The system uses sensor electrodes to continuously monitor physiological signals and adjusts stimulation intensity accordingly. This feedback mechanism ensures that stimulation remains within safe and comfortable limits while maintaining adequate control effectiveness, preventing both understimulation and overstimulation.
Solution Approach 2:
Stimulation parameters are dynamically adjusted based on real-time physiological feedback rather than using a fixed high intensity. The system can modulate intensity levels to match the subject's condition, ensuring adequate control without causing discomfort or overstimulation.
