Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power supply is used to implant a medical device in the body, then the device can be powered without physical connections, but the control cannot adapt to the living body state and places a burden on the operator
Solution Approach 1:
The patent implements feedback control by acquiring living body information through sensors, analyzing the living body state, and using this information to automatically adjust stimulation parameters. The control device receives feedback from the living body state and modifies stimulation intensity, frequency, and duration accordingly, eliminating the need for manual operator adjustment while adapting to changing physiological conditions.
Solution Approach 2:
The system enables self-service control where the medical device automatically adjusts its stimulation parameters based on real-time living body state monitoring. The device independently analyzes sensor data, determines appropriate stimulation settings, and executes control without requiring continuous operator intervention, thereby improving ease of operation while managing complexity through automation.
2Productivity
If manual control is used for implanted medical devices, then the system is simple to operate, but it places a burden on both the operator and the patient
Solution Approach 1:
The system uses feedback from living body state sensors to automatically adjust stimulation parameters in real-time. This eliminates the need for operators to continuously monitor and manually adjust settings, significantly improving control efficiency and reducing the time operators need to spend managing the device while maintaining optimal therapeutic效果.
Solution Approach 2:
The patent replaces manual mechanical control with automated electronic control systems. Sensors, processors, and wireless communication components work together to substitute human operator actions with automated electronic decision-making and parameter adjustment, thereby increasing productivity and reducing operator time requirements.
3Reliability
If continuous stimulation is provided to ensure therapeutic effect, then the treatment effectiveness is maintained, but the energy consumption increases
Solution Approach 1:
The system implements periodic stimulation based on detected living body state patterns rather than continuous stimulation. By analyzing rhythmic physiological signals and providing stimulation only during appropriate phases or when specific thresholds are met, the system maintains treatment effectiveness while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The patent applies dynamic control where stimulation parameters are continuously adjusted based on real-time living body state monitoring. The system transitions between different stimulation states (on/off, high/low intensity) dynamically responding to physiological changes, ensuring reliable therapeutic effect only when and where needed, thereby optimizing energy usage while maintaining treatment reliability.
