Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles use radio-based navigation and communication devices, then navigation and communication capabilities are provided, but vulnerability to signal interference from high energy electromagnetic radiation emitters occurs
Solution Approach 1:
The system performs preliminary identification of HE EM radiation emitters and pre-determines interference-controlled routings before the vehicle encounters interference problems. The database stores pre-mapped locations of HE EM radiation emitters and their interference patterns, allowing the vehicle to proactively select safe routes rather than reacting to interference after it occurs.
Solution Approach 2:
The processing module acts as an intermediary between the vehicle's navigation system and the environmental interference. It queries the database to determine interference levels along proposed routes and selects alternative routings that avoid HE EM radiation zones, mediating between the vehicle's navigation needs and the harmful electromagnetic environment.
2Reliability
If vehicles follow previously determined interference-controlled paths, then protection from signal interference is achieved, but ability to depart from routings for performance or threat avoidance is limited
Solution Approach 1:
The system dynamically generates alternative routings based on real-time queries to the database rather than following fixed predetermined paths. When interference is detected or anticipated, the processing module can compute new routes on-demand, allowing the vehicle to adapt its path dynamically while maintaining protection from interference through database-guided route selection.
Solution Approach 2:
The system changes routing parameters dynamically by querying the database for alternative paths that satisfy interference constraints. Instead of being locked into fixed routes, the vehicle can request and implement different routings (alternative frequencies and stations) based on current operational needs while maintaining compliance with interference control requirements.
3Adaptability or versatility
If vehicles autonomously determine interference-controlled routings, then navigation flexibility is improved, but capability to identify and avoid HE EM radiation threats is insufficient
Solution Approach 1:
The vehicle autonomously queries the database using its own position and proposed routing information to determine interference threats. The processing module self-services by automatically comparing the vehicle's intended path against the stored HE EM radiation emitter locations and interference patterns, enabling autonomous identification of threats without external assistance.
Solution Approach 2:
The system implements feedback by continuously monitoring the vehicle's position, querying the database for interference conditions along the current and proposed routes, and adjusting routing recommendations based on the retrieved interference information. This closed-loop feedback ensures the vehicle maintains awareness of HE EM radiation threats and adapts its path accordingly.

AI summary
A system for providing the capability for a vehicle to avoid regions of signal interference from high energy (HE) electromagnetic (EM) radiation emitters. The system includes a processing module. A database is operatively connected to the processing module. The database comprises a plurality of geographical areas affected by HE EM radiation emitters and data associated with the geographical areas. The data includes location, lateral and vertical extents, and signal attenuation for selected geographical areas affected by HE EM radiation emitters. The data preferably also includes affected frequency spectrum for the selected geographical areas. A display system is operatively connected to the processing module. The processing module functions to receive information regarding the position of the vehicle and query the database to retrieve relevant HE EM radiation emitters which are a threat to the vehicle's ability to properly navigate or communicate. The relevant HE EM radiation emitters are displayed on the display system. The present invention provides enhanced situational awareness to the pilot and permits decision support systems to refine their trajectory through hazards.
