Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed frequency pulses are used for stimulation, then the system is simple to operate, but the adaptability to individual brain frequencies is poor
Solution Approach 1:
The stimulation system dynamically adjusts the frequency of pulses based on the user's intrinsic brain frequency detected through EEG signals. The frequency parameter is made variable rather than fixed, allowing the system to adapt to individual differences in brain oscillation patterns while maintaining ease of operation through automated adjustment.
Solution Approach 2:
The system changes the frequency parameter of the stimulation pulses to match the detected intrinsic frequency of the user's brain activity. By measuring EEG signals and identifying the dominant frequency, the system modifies the stimulation frequency parameter in real-time to achieve resonance with the target brain region, thereby improving therapeutic efficacy.
2Adaptability or versatility
If variable frequency stimulation is implemented to match individual brain frequencies, then adaptability improves, but device complexity increases
Solution Approach 1:
The head-mounted device integrates multiple functions into a single unit: EEG signal acquisition, intrinsic frequency detection, stimulation pulse generation, and real-time frequency adjustment. This multi-functional integration allows the system to adapt to individual brain frequencies without requiring multiple separate devices, thereby managing complexity through consolidation.
Solution Approach 2:
The system automatically detects the user's intrinsic brain frequency through EEG sensors and autonomously adjusts the stimulation frequency without requiring manual input or complex configuration by the user. This self-adjusting capability reduces the operational complexity burden on the user while maintaining high adaptability to individual neural characteristics.
3Ease of operation
If traditional rTMS or tACS systems are used with fixed pulse trains, then the treatment protocol is simple to implement, but the therapeutic efficacy for individualized treatment is limited
Solution Approach 1:
The system incorporates real-time feedback through EEG monitoring to detect the user's intrinsic brain frequency and automatically adjusts the stimulation parameters accordingly. This closed-loop feedback mechanism ensures that the stimulation remains synchronized with the target brain oscillations, thereby improving therapeutic efficacy while maintaining protocol simplicity through automated control.
Solution Approach 2:
The system performs preliminary detection of the user's intrinsic brain frequency before initiating the stimulation protocol. By measuring EEG signals and identifying the dominant frequency in advance, the system pre-configures the optimal stimulation parameters, ensuring that the subsequent treatment is immediately effective without requiring complex real-time adjustments during the protocol execution.
