Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alpha burst stimulation is provided to treat mental disorders and enhance cognitive functions, then brain health and cognitive performance are improved, but the brain's natural variability in alpha frequency makes it difficult to accurately determine and optimize stimulation parameters
Solution Approach 1:
The system performs preliminary measurement and characterization of the subject's intrinsic alpha frequency parameters (AFV and AP) before delivering the stimulation treatment. This preliminary action allows the system to establish baseline values and optimize stimulation parameters tailored to each individual's brain characteristics, thereby resolving the contradiction between treatment effectiveness and measurement accuracy by preparing the optimal stimulation protocol in advance
Solution Approach 2:
The system continuously monitors alpha burst parameters during stimulation and uses this feedback to dynamically adjust stimulation frequency and intensity. By comparing real-time measurements against target values for AFV and AP, the system maintains precise control over stimulation parameters despite natural brain variability, ensuring both measurement accuracy and treatment effectiveness
2Ease of operation
If standardized stimulation frequencies are used for alpha burst brain stimulation, then the stimulation protocol is simple to implement, but it cannot account for individual differences in intrinsic alpha frequency
Solution Approach 1:
The system transitions from static, standardized stimulation frequencies to dynamic, adaptive frequency selection based on each subject's measured intrinsic alpha parameters. The stimulation protocol automatically adjusts frequency and other parameters in real-time or near-real-time based on individual brain state measurements, maintaining ease of operation through automation while achieving full personalization
Solution Approach 2:
The system changes key stimulation parameters (frequency, intensity, duration) based on measured individual differences in alpha burst characteristics. By adjusting these parameters to match each subject's specific AFV and AP values, the system achieves personalized treatment while maintaining a user-friendly interface that handles the complexity automatically
