Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If geometric optimizations are used for stealth, then radar detectability is reduced, but the system cannot be dynamically adapted to changing situations
Solution Approach 1:
The patent applies plasma actuators that can be dynamically activated and deactivated to change the electromagnetic properties of the surface in real-time, transforming a static geometric stealth solution into a dynamic adaptive system that can respond to changing radar threats
Solution Approach 2:
The invention changes the physical state of the surface by generating plasma, which alters the electromagnetic impedance and radar cross-section dynamically, allowing the system to adapt its radar signature based on operational requirements
2Object-affected harmful factors
If passive stealth measures are used, then radar cross-section is reduced, but the system lacks active control capability
Solution Approach 1:
The patent incorporates detection units that sense incoming electromagnetic radiation and feed this information back to control units, which then activate plasma actuators to dynamically adjust the radar signature in response to detected threats
Solution Approach 2:
The system uses its own detection capabilities to automatically trigger plasma generation without external control, enabling autonomous adaptation to radar threats through integrated sensing and actuation
3Adaptability or versatility
If plasma actuators are added for active control, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent divides the surface into multiple zones with independent plasma actuators and control units, allowing localized electromagnetic signature modification without requiring system-wide changes, thereby managing complexity through modular segmentation
Solution Approach 2:
The plasma actuators serve multiple functions including radar signature control, electromagnetic interference mitigation, and potential communication enhancement, reducing the need for separate specialized systems and overall complexity
