Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted using traditional aircraft communications addressing and reporting system links, then reliability is maintained for safety-critical communications, but operational costs increase and bandwidth is limited
Solution Approach 1:
The patent segments data transmission into two separate pathways: traditional ACARS links for safety-critical data and Internet protocol links for non-safety data. This segmentation allows each communication channel to be optimized for its specific purpose, maintaining reliability for essential communications while reducing costs for routine data transmission.
Solution Approach 2:
The patent introduces an intermediary routing system that determines whether data should be transmitted via ACARS or Internet protocol links based on data type and availability. This intermediary layer enables intelligent selection of transmission pathways, ensuring safety-critical data uses reliable ACARS while other data utilizes cost-effective Internet links.
2Loss of information
If data volume transmitted from aircraft to ground station increases, then information completeness improves, but transmission cost increases proportionally
Solution Approach 1:
The patent segments data into safety-critical and non-safety categories, transmitting only essential safety data through expensive ACARS links while routing other data through cost-effective Internet protocol links. This segmentation maintains information completeness for safety purposes while dramatically reducing overall transmission costs.
Solution Approach 2:
The patent applies different transmission qualities and channels to different types of data based on their importance. Safety-critical data receives premium treatment through reliable ACARS links, while non-critical data uses economical Internet links, optimizing the balance between information completeness and cost.
3Device complexity
If traditional aircraft communications links are used for all data transmission, then system simplicity is maintained, but transmission speed and bandwidth are limited
Solution Approach 1:
The patent makes the communication system universal by enabling it to handle both traditional ACARS communications and modern Internet protocol communications through a single integrated architecture. This multi-functionality allows the system to maintain simplicity for legacy safety communications while incorporating high-speed Internet links for additional data transmission capacity.
