Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional communication systems are used for data transfer between aircraft and ground-based systems, then data transmission can be established, but the systems are insecure, lack standardization, and have varying availability across different airports
Solution Approach 1:
The patent applies universality by using the electrical power cable as a multi-functional medium that serves both power transmission and data communication purposes. The BPL communication channel is established over the existing power infrastructure, allowing the same cable to perform dual functions without requiring separate communication wiring between aircraft and ground systems.
Solution Approach 2:
The patent introduces BPL communication technology as an intermediary that enables data transmission through the power cable infrastructure. The biometric authentication system acts as another intermediary layer that mediates access control, ensuring that only authorized users can establish communication channels, thereby resolving the security and compatibility issues of traditional systems.
2Reliability
If biometric authentication is implemented for BPL communication channel establishment, then data security is enhanced, but system complexity increases
Solution Approach 1:
The biometric authentication system applies self-service by using the user's own biometric characteristics (fingerprint, iris, facial features, etc.) as the authentication credential. The system automatically captures, processes, and verifies biometric data without requiring manual credential entry or external authentication agents, thereby enhancing security while keeping the operational process simple.
Solution Approach 2:
The patent replaces traditional mechanical authentication methods (physical keys, cards, or passwords) with biometric authentication. This substitution uses biological characteristics instead of physical or memorized credentials, enhancing security while simplifying the user interaction process through automatic biometric capture and verification.
3Adaptability or versatility
If BPL communication channels are established through electrical power cables, then standardized data transmission is achieved, but interference with power transmission may occur
Solution Approach 1:
The patent applies segmentation by dividing the electrical power cable into functionally distinct segments or channels. The BPL communication system uses specific frequency ranges or time slots within the power cable's capacity, separating data transmission from power transmission to minimize interference while utilizing the same physical infrastructure.
Solution Approach 2:
The patent resolves interference by adding another dimension to the power cable's functionality - using frequency dimension for BPL communication while maintaining the power transmission function. By operating in different frequency domains, the system enables simultaneous power and data transmission through the same cable without significant interference.

AI summary
Provided are methods and systems for transmission of terrestrial data between aircraft and ground-based systems using broadband over power line (BPL) communication channels. These channels are established based on authentication of biometric data. Specifically, a biometric module, positioned on an aircraft or a gate, receives biometric data from a user and then authenticates this data based on available reference data. The authentication results are used by a BPL module to establish (or not establish) a BPL communication channel. The BPL communication channel is established through an electrical power cable connecting the aircraft to the gate. Furthermore, the BPL communication channel is established through at least a portion of the onboard electrical power distribution system of the aircraft. The terrestrial data, e.g., aircraft control data, in-flight entertainment data, and/or airplane information system data, is then transmitted through this BPL communication channel.
