Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric wires and implanted power sources are used in conventional DBS devices, then power supply and data transmission are achieved, but device complexity and surgical intervention frequency increase due to wire short-circuits and battery consumption
Solution Approach 1:
The patent extracts and removes the power source and electric wires from the implanted device, placing the power source externally. The implanted device contains only the electrode array and control circuitry, eliminating the need for internal battery implantation and wire connections through the skin, thereby reducing surgical complexity and improving reliability
Solution Approach 2:
The patent introduces a wireless power and data transmission system as an intermediary between the external power source and the implanted electrode array. This intermediary enables power and signal transmission without physical wire connections, eliminating short-circuit risks and reducing the need for repeated surgical interventions
2Reliability
If electric wires are used for power transmission in DBS devices, then power supply is achieved, but short-circuits occur leading to frequent surgical repairs
Solution Approach 1:
The patent removes the vulnerable electric wires from the system by using wireless power transmission. The power source is extracted from the implanted device and placed externally, eliminating the physical connection that causes short-circuits and simplifies maintenance
Solution Approach 2:
The patent replaces the mechanical wire connection system with a wireless electromagnetic field-based power transmission system. This substitution eliminates physical wear, short-circuits, and connection failures, significantly improving reliability and reducing maintenance requirements
3Measurement precision
If conventional DBS devices are used, then deep brain stimulation is achieved, but real-time monitoring and accurate control of specific brain areas are limited
Solution Approach 1:
The patent creates a multi-functional implanted device that combines both monitoring and stimulation capabilities. The electrode array serves dual purposes: recording neural activity for real-time monitoring and delivering stimulation pulses for therapy, enabling accurate control of specific brain areas with a single integrated system
Solution Approach 2:
The patent implements a closed-loop feedback system where the implanted device continuously monitors brain activity and uses this information to adjust stimulation parameters in real-time. This feedback mechanism enables precise control of specific brain areas by adapting stimulation based on actual neural activity patterns
