Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas of different sizes and shapes are used to target various brain regions, then the ability to stimulate different brain regions is improved, but the device complexity and time required for changes increases
Solution Approach 1:
The antenna is divided into multiple selectable portions or segments, each capable of being independently connected to the current-generating device. This allows a single antenna structure to provide multiple functional configurations, replacing the need for multiple separate antennas while maintaining the ability to target different brain regions with appropriate spatial resolution
Solution Approach 2:
A single antenna is designed to perform multiple functions by selectively connecting different portions to the current-generating device. The antenna serves as a universal component that can stimulate various brain regions through configuration selection, eliminating the need for multiple specialized antennas
2Manufacturing precision
If multiple antennas of different sizes and shapes are used to target various brain regions, then the spatial resolution for different regions is improved, but the time required to change antennas increases
Solution Approach 1:
The antenna configuration is made dynamically selectable through switching mechanisms that allow rapid reconfiguration between different portions. This dynamic selection capability enables quick adaptation between different spatial resolution requirements without the time-consuming process of physically changing antennas
3Device complexity
If a single antenna is used for all brain regions, then the device complexity is reduced, but the spatial resolution and penetration capacity for specific regions deteriorates
Solution Approach 1:
The single antenna is segmented into multiple portions with different geometric characteristics. By selecting and activating specific portions through switching mechanisms, the system maintains the spatial resolution and penetration capacity benefits of specialized antennas while using a single physical antenna structure
Solution Approach 2:
Different portions of the antenna are designed with local geometric optimizations suited for specific brain region stimulation requirements. Each portion maintains the quality characteristics needed for its intended target region, while the switching mechanism allows selection of the appropriate local quality configuration
