Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If implantable medical devices use manual intervention for stimulus delivery, then device complexity is reduced, but treatment adaptability and real-time response capability deteriorate
Solution Approach 1:
The system is divided into an implantable medical device for real-time biometric monitoring and an external device for stimulus delivery and control. This segmentation allows the implantable device to remain relatively simple while the external device handles complex adaptive control algorithms, resolving the contradiction between treatment adaptability and device complexity.
Solution Approach 2:
A wireless communication system acts as an intermediary between the implantable device and the external control system. This intermediary enables real-time data transfer for adaptive stimulus delivery without requiring complex processing within the implantable device itself, maintaining simplicity while achieving high adaptability.
2Ease of operation
If implantable medical devices require frequent manual adjustment, then ease of operation is reduced, but measurement precision and control accuracy are maintained
Solution Approach 1:
The system implements automatic feedback control where the implantable device continuously monitors biometric parameters and wirelessly transmits this data to an external device that automatically adjusts stimulus parameters in real-time. This eliminates the need for manual adjustment, significantly improving ease of operation and reducing the time loss associated with manual interventions.
Solution Approach 2:
The closed-loop system enables the medical device to self-adjust stimulus delivery based on real-time biometric feedback without requiring user intervention. The device automatically adapts to changing patient conditions, making operation extremely easy while maintaining precise control.
3Ease of operation
If wireless power and data transmission are used, then ease of operation and patient comfort are improved, but energy consumption and device complexity increase
Solution Approach 1:
The wireless power and data transmission operate in periodic intervals rather than continuously. The implantable device transmits biometric data at scheduled intervals and receives stimulus control commands periodically, which significantly reduces energy consumption compared to continuous transmission while maintaining effective real-time monitoring and control capabilities.
