Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless transmission of stimulus information and power is implemented, then treatment efficacy and real-time response capability are improved, but device complexity and energy consumption increase
Solution Approach 1:
The system divides functionality between internal device (stimulus application, biometric sensing) and external device (stimulus information transmission, power transmission, control), allowing each component to be optimized independently while reducing overall system complexity
Solution Approach 2:
The external device performs multiple functions including transmitting stimulus information, transmitting power wirelessly, and receiving biometric data, consolidating these functions into a single integrated system that improves treatment efficacy without proportionally increasing complexity
2Ease of operation
If wireless power transmission is used to drive internal device, then ease of operation and patient management are improved, but energy loss and transmission efficiency deteriorate
Solution Approach 1:
The system uses biometric information feedback to dynamically adjust stimulus parameters and power transmission levels, optimizing energy efficiency by transmitting only the necessary amount of power required for effective treatment
Solution Approach 2:
The stimulus information and power transmission are dynamically adjusted based on real-time biometric data, allowing the system to adapt power levels to actual physiological needs rather than using fixed high-power transmission
3Speed
If real-time biometric monitoring and stimulus application are implemented, then treatment responsiveness is improved, but device complexity and control requirements increase
Solution Approach 1:
Complex control functions including stimulus pattern selection, parameter adjustment, and treatment protocol management are extracted from the implantable device and placed in the external device, reducing the complexity burden on the internal medical device while enabling real-time responsiveness
