Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If defibrillators are used for electrical stimulation, then stimulation current can be delivered to treat essential tremor, but the control of stimulation signal output cannot achieve dynamic smooth control or precise control
Solution Approach 1:
The patent implements dynamic control of stimulation signals by enabling real-time adjustment of stimulation parameters including frequency, pulse width, and amplitude. The system transitions from fixed static stimulation to dynamic adaptable stimulation that can respond to changing physiological conditions, achieving smooth control through continuous parameter modulation rather than discrete on/off states.
Solution Approach 2:
The patent applies parameter changes by systematically varying multiple stimulation parameters (frequency, pulse width, amplitude, duty cycle) to achieve precise control of the electrical stimulation output. This multi-parameter control approach enables fine-tuned adjustment of stimulation effects, allowing the device to deliver therapeutically optimal signals with high precision.
2Adaptability or versatility
If defibrillators perform regular stimulation at fixed locations in a fixed stimulation mode, then the device operation is simple, but the neural system adapts to the stimulation mode and the therapeutic effect diminishes
Solution Approach 1:
The patent implements dynamic stimulation patterns that vary over time, including randomization of stimulation delivery timing and parameter modulation. This dynamic approach prevents the neural system from adapting to fixed patterns, maintaining therapeutic effectiveness by continuously changing the stimulation regime rather than using static repeated patterns.
Solution Approach 2:
The patent employs periodic action through structured variation of stimulation parameters at different time scales. This includes rhythmic modulation of stimulation intensity, alternating between different stimulation modes, and using periodic patterns that adapt to physiological rhythms while preventing neural adaptation through controlled variability.
3Ease of operation
If fixed stimulation mode is used, then the device is easy to operate, but user experience is poor and disease relief is ineffective
Solution Approach 1:
The patent implements self-service functionality through automated parameter adjustment and adaptive control algorithms that automatically optimize stimulation parameters based on physiological feedback. The system self-regulates stimulation delivery without requiring manual intervention, maintaining ease of operation while achieving reliable therapeutic effects through intelligent autonomous control.
Solution Approach 2:
The patent applies feedback mechanisms by incorporating sensors and control systems that monitor physiological responses and adjust stimulation parameters in real-time. This closed-loop control ensures therapeutic effectiveness is maintained while the system adapts to individual patient needs, combining ease of operation with reliable disease relief through automated feedback-driven optimization.
