Engineering Contradiction Analysis
1Productivity
If manual data collection methods are used with data recording devices coupled to aircraft interfaces, then data transfer can be performed without additional physical connections, but the data transfer process is time-consuming and inefficient
Solution Approach 1:
The patent replaces manual mechanical data collection processes with automated electronic data transfer systems. The system automatically retrieves data from aircraft systems through electronic interfaces and transmits it to ground systems, eliminating the need for manual data recording device coupling and significantly improving transfer efficiency while reducing time loss.
Solution Approach 2:
The system performs preliminary data preparation and formatting before transmission. Data is pre-processed, validated, and organized on the aircraft side before the actual transfer occurs, which streamlines the overall data collection process and reduces the time required during actual data transfer operations.
2Productivity
If additional communication channels are installed on the aircraft, then data transmission capacity increases, but the aircraft structure requires additional holes to be drilled
Solution Approach 1:
The patent makes existing aircraft power line infrastructure multi-functional by enabling it to carry both electrical power and data communication signals simultaneously. This approach allows the power distribution system to serve dual purposes, eliminating the need for separate communication channels and avoiding additional structural modifications to the aircraft.
Solution Approach 2:
The system merges power transmission and data communication functions into a single infrastructure. By combining these two functions in the existing power lines, the patent avoids the need for additional communication channels and the structural modifications they would require, while still achieving high data transmission capacity.
3Ease of operation
If data is transmitted over existing power lines, then additional physical connections are avoided, but data security and integrity become compromised
Solution Approach 1:
The patent introduces intermediary components including encryption modules and validation systems that process data before it traverses the power line infrastructure. These intermediaries ensure that sensitive data is encrypted and authenticated, maintaining security and integrity while still utilizing the convenient existing power line connections for data transmission.
Solution Approach 2:
The system changes the state parameters of data transmission by applying encryption transforms and validation protocols to the data stream. These parameter changes ensure that even though data travels over existing power lines, the security and integrity are maintained through cryptographic protection and error detection mechanisms.
4Productivity
If multiple data streams are transmitted simultaneously over power lines, then communication efficiency improves, but signal interference and noise increase
Solution Approach 1:
The patent segments the data transmission by assigning different data streams to different phases of the three-phase power system. This segmentation allows multiple data streams to be transmitted simultaneously over the power lines without interfering with each other, as each phase operates independently, thereby maintaining high communication efficiency while minimizing signal interference.
Solution Approach 2:
The system transitions from single-dimensional data transmission to three-dimensional transmission by utilizing all three phases of the power system. This dimensional expansion allows parallel transmission of multiple data streams without interference, as each phase provides an independent transmission channel, thus improving communication efficiency while avoiding the harmful effects of signal interference.
