Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple magnetic coil channels are operated simultaneously with different parameters, then the versatility and precision of magnetic field applications are improved, but the device complexity and control difficulty increase
Solution Approach 1:
The system divides the magnetic coil driver into multiple independent channels, each capable of being controlled separately with different parameters. Each channel can be independently adjusted to deliver different output magnetic energy, allowing precise targeting of different brain regions or application areas while maintaining overall system coordination through a main controller.
2Power
If high power magnetic fields are generated for deep brain stimulation, then the therapeutic effectiveness is improved, but the risk of harmful effects and safety concerns increase
Solution Approach 1:
The system incorporates feedback mechanisms that continuously monitor the magnetic field output and adjust the drive signals accordingly. This feedback control allows the system to maintain high power output when needed for effective deep brain stimulation while automatically reducing power or shutting down if safety thresholds are approached, thereby preventing harmful effects.
3Power
If capacitor banks are used to power each magnetic coil channel, then the ability to deliver high power pulses is improved, but the energy consumption and heat generation increase
Solution Approach 1:
The capacitor banks are charged during idle periods between magnetic pulse deliveries and then rapidly discharged to provide high power pulses when needed. This periodic charging and discharging allows the system to maintain high power delivery capability while minimizing average energy consumption, as the capacitors store energy efficiently during charging phases and release it only when required for stimulation.
