Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication techniques between aircrafts are vulnerable to detection by third parties, particularly when data transmission is interrupted by terrain, as they rely on simple relaying methods that do not effectively minimize detection risks.
Innovation Solution
A data communication system that uses a configuration of aircrafts equipped with detection sensors, location sensors, and a controller to assess and minimize the detection possibility by a third party, by selecting the aircraft with the lowest detection possibility to relay data when transmission is interrupted, utilizing positional information and terrain data to optimize communication paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simple relaying method is used to transmit data when direct transmission is interrupted by terrain, then data communication can be maintained, but the possibility of detection by third party increases
Solution Approach 1:
The patent introduces an intermediary aircraft that performs intelligent relay of data between transmission source and destination. This intermediary evaluates detection possibilities using sensor data and positional information, then selectively relays data only when detection risk is low, thus maintaining communication reliability while reducing detection probability compared to simple relaying methods
Solution Approach 2:
The system dynamically changes operational parameters including selecting different relay aircraft based on real-time evaluation of detection possibility, transmission power levels, and data relay timing. By adjusting these parameters based on environmental conditions and positional information, the system maintains communication reliability while optimizing security against third-party detection
2Object-affected harmful factors
If intelligent relay with detection assessment is implemented, then detection possibility is reduced, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by equipping relay aircraft with both normal communication functions and security evaluation functions. The same aircraft performs data relay, detection possibility assessment using sensors, and decision-making, eliminating the need for separate security infrastructure and reducing overall system complexity while maintaining enhanced security
Solution Approach 2:
Each aircraft in the system performs self-assessment of detection possibility using its own sensors and positional information. The system is self-organizing where aircraft autonomously evaluate security conditions and make relay decisions without centralized control, reducing the complexity of coordination and control infrastructure

AI summary
A data communication system (1) includes an information acquiring unit (13, 14) and a selector (18). The information acquiring unit (13, 14) acquires positional information of a third party (T) capable of detecting data communication performed between communication bodies (10), positional information of each of the communication bodies (10), and terrain information. The selector (18) selects a fourth communication body from third communication bodies when transmission of transmission data from a first communication body to a second communication body out of the communication bodies (10) is not successful. The third communication bodies are remaining communication bodies out of the communication bodies (10) excluding the first and the second communication bodies and successful in receiving the transmission data from the first communication body. The fourth communication body is lowest in a possibility that the data communication is detected by the third party (T) out of the third communication bodies, and transmits the transmission data to the second communication body.
