Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If modular electrodes are used for electrical stimulation, then ease of operation and device flexibility are improved, but it becomes difficult to determine when electrode replacement is needed, leading to potential degradation in stimulation quality and safety
Solution Approach 1:
The system incorporates usage tracking that monitors electrode usage metrics and provides feedback to both users and clinicians. The electrode usage module tracks cumulative usage, session counts, and performance metrics, then communicates this information through the system interface to indicate when electrodes should be replaced, ensuring both ease of use and maintained reliability.
Solution Approach 2:
The electrode system performs self-monitoring of its own usage and condition through integrated sensors and tracking modules. The electrodes automatically record their own usage history, connection status, and performance metrics without requiring external monitoring, enabling the system to self-determine when replacement is necessary.
2Reliability
If electrode usage tracking is implemented, then stimulation safety and quality are improved, but device complexity increases due to additional monitoring and control components
Solution Approach 1:
The system employs multi-functional components that perform multiple roles. For example, the electrode assembly serves both as the stimulation interface and as a sensor for monitoring usage and condition. The control module handles both stimulation delivery and usage tracking functions, reducing the need for separate dedicated components and thereby limiting the increase in overall device complexity.
3Reliability
If continuous monitoring of electrode condition is performed, then stimulation efficacy and user safety are improved, but energy consumption increases due to ongoing measurement and data processing
Solution Approach 1:
The monitoring system operates periodically rather than continuously, checking electrode condition at predetermined intervals such as at the start of each stimulation session or at scheduled time points. This periodic monitoring approach maintains adequate oversight of electrode status while significantly reducing energy consumption compared to continuous monitoring.
