Engineering Contradiction Analysis
1Reliability
If remote operation system is used for passenger boarding bridges, then operator safety and reduced idle time are improved, but operational accuracy deteriorates due to latency in command execution
Solution Approach 1:
The system predicts the desired position of the bridge based on recent command history and sends this predicted position as a preliminary command to the actuator. This anticipatory action compensates for the latency in command execution, ensuring the bridge reaches the correct position despite the time delay between operator input and actuator response.
Solution Approach 2:
The system continuously receives feedback from position sensors that report the actual position of the bridge. This feedback is used to calculate the position error between the desired and actual positions, which then drives the prediction algorithm to generate more accurate future commands, thereby maintaining operational accuracy despite remote operation latency.
2Adaptability or versatility
If multiple trained operators are deployed to handle high air traffic volume, then service coverage is improved, but time utilization deteriorates due to extensive idle and waiting time
Solution Approach 1:
The bridge equipping system incorporates autonomous functions including automatic position detection via sensors, automated connection/disconnection operations, and self-diagnosis capabilities. These self-service features reduce the need for continuous human intervention, allowing operators to handle multiple bridges simultaneously and significantly reducing idle time while maintaining service coverage.
Solution Approach 2:
The system replaces manual mechanical operations with automated electronic control and actuation. Position sensors, motorized actuators, and control algorithms substitute for manual positioning and connection operations, enabling faster and more efficient bridge management with reduced operator involvement and improved time utilization.

AI summary
A remote operation system for passenger boarding bridges for craft comprises display means to display the environment of the bridge. Image-capture means is designed to capture an area around the bridge. Interaction means allowing a user-controller to interact with the system is designed such that the user/controller can introduce and/or alter operating parameters for the system. Manual control means is accessible to the user/controller of the system. Indicator means indicates an operating situation of the bridge. These means linked by means of a control unit that controls movement elements of the bridge. The control unit incorporates a correction circuit for latency management through software, establishing latency values in the signals generated from the interaction means to the movement elements of the bridge, such that in the event that the control unit detects a value greater than the predetermined latency value, the control unit generates a signal that activates emergency stop means that are provided on movement elements of the bridge.
