Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hand signals and radio communications are used to coordinate task completion, then personnel can communicate task status, but miscommunication and delays occur reducing reliability
Solution Approach 1:
The patent replaces manual communication methods (hand signals and radio communications) with an automated electronic system using RFID tags and mobile devices. Task completion is automatically detected when a mobile device scans an RFID tag, eliminating human error in communication and automatically notifying the coordination system, thus improving both reliability and reducing turnaround time.
2Reliability
If manual coordination methods are used, then system complexity is low, but communication errors increase reducing reliability
Solution Approach 1:
The patent introduces RFID tags as intermediary objects between task completion actions and system verification. The RFID tags are placed at task locations and automatically verify completion when scanned, serving as a reliable intermediary that confirms task status without complex manual verification procedures, thereby improving reliability while keeping the system relatively simple.
3Measurement precision
If electronic devices and RFID tags are deployed throughout the aircraft, then task completion accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the aircraft into discrete task zones, each marked with an RFID tag. This segmentation allows precise tracking of task completion in specific locations without requiring a fully integrated complex system throughout the entire aircraft. Each RFID tag independently verifies completion of its associated task, providing high measurement precision through distributed simple components.
