Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current is supplied to both electrodes simultaneously, then therapeutic effect is enhanced, but battery life is depleted rapidly
Solution Approach 1:
The patent implements periodic action by alternating current supply between two electrodes in a cyclic manner. The controller switches the current supply from the first electrode to the second electrode and back repeatedly, ensuring that each electrode receives current in periodic intervals rather than simultaneously. This periodic activation maintains therapeutic effectiveness while reducing overall power consumption, thereby extending battery life.
Solution Approach 2:
The patent applies dynamics by making the electrode selection dynamic rather than static. The controller dynamically switches which electrode receives current based on a predetermined switching cycle, adapting the current distribution over time. This dynamic switching mechanism allows the system to maintain therapeutic effect through alternating stimulation while managing battery consumption efficiently.
2Duration of action of stationary object
If current is supplied to one electrode continuously, then battery life is extended, but therapeutic effect may be insufficient
Solution Approach 1:
The patent uses periodic action to alternate current supply between two electrodes, ensuring that each electrode receives sufficient stimulation over time to maintain therapeutic effect. By switching between electrodes in a predetermined cycle, the system provides continuous therapeutic coverage without requiring both electrodes to be active simultaneously, thus conserving battery power while maintaining treatment efficacy.
3Duration of action of stationary object
If two electrodes are used with alternating current supply, then battery life is extended, but device complexity increases
Solution Approach 1:
The patent implements periodic action through a controller that automatically switches current supply between two electrodes according to a predetermined switching cycle. This automated periodic switching extends battery life by ensuring electrodes are not simultaneously active, while the control complexity is managed through systematic timing mechanisms rather than complex decision-making algorithms.
Solution Approach 2:
The system employs self-service through an automated controller that manages the electrode switching without requiring external intervention. The controller independently monitors and switches current supply between electrodes based on predetermined parameters, reducing the need for complex external control systems and minimizing user burden while extending battery life.

AI summary
According to a deep brain stimulation device and a control method thereof according to one embodiment of the present invention, two electrodes are inserted into a deep brain nucleus and supplied with high-frequency current in order to treat brain and neural diseases such as Parkinson's disease, tremor, myodystonia, Alzheimer's dementia, epilepsy, obsessive compulsive disorder, depression, pain, drug addiction, and post-traumatic syndrome, wherein the two electrodes are not supplied with current at the same time, thus making it possible to extend the life of a battery while achieving treatment effects that are the same as or superior to the prior art.
