Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If aircraft and aerial platforms use conductive materials for construction, then structural strength and electrical conductivity are improved, but susceptibility to lightning strikes increases
Solution Approach 1:
The system applies preliminary anti-action by detecting the formation of ionized plasma channels (leaders) before they can establish a complete discharge path, and actively disrupting them through electromagnetic wave transmission. This prevents the harmful lightning strike before it can occur, while allowing the use of conductive materials for structural strength.
2Reliability
If active lightning prevention systems transmit electromagnetic waves to disrupt plasma channels, then lightning strike prevention is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic action by continuously monitoring electric field conditions and only transmitting electromagnetic waves when ionized plasma channels are detected above a threshold. This on-demand operation reduces energy consumption compared to continuous transmission, while maintaining reliable lightning prevention when needed.
3Reliability
If electromagnetic waves are transmitted to collapse ionized plasma channels, then leader attachment prevention is improved, but system complexity increases
Solution Approach 1:
The system uses an intermediary approach by employing sensors to detect ionized plasma channels and a control system to coordinate the transmission of electromagnetic waves from antennas. This intermediary detection and control mechanism enables reliable leader attachment prevention while managing system complexity through modular functional components.
