Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to efficiently manage Unit Load Devices (ULDs) within airports, facing challenges in allocation, deallocation, usage, movement, storage, and maintenance due to the increasing number of ULDs and static airport space.
Innovation Solution
An Intelligent Autonomous ULD Control Tower (IAUCT) is implemented, which identifies ULD states and positions, stores this information, and dynamically optimizes routes for ULD movement based on demand, using autonomous vehicles to allocate and manage ULDs within the airport perimeter.

Engineering Contradiction Analysis
1Quantity of substance
If the number of ULDs is increased to meet growing cargo demand, then cargo capacity is improved, but the difficulty of managing ULD allocation, movement, and storage increases
Solution Approach 1:
The system implements continuous feedback loops where ULD sensors transmit real-time data (location, status, weight) to the control tower, which processes this information and sends back control commands. This closed-loop feedback system enables automated tracking and management of numerous ULDs, reducing the complexity of handling increased quantities while maintaining optimal allocation and movement coordination.
Solution Approach 2:
ULDs are equipped with autonomous capabilities including self-tracking via sensors, self-reporting of status and location, and self-navigation to designated destinations. This self-service approach allows each ULD to manage its own operational parameters, significantly reducing the management burden when the number of ULDs increases, as the system becomes increasingly autonomous rather than requiring proportional increases in manual management resources.
2Productivity
If manual tracking and routing of ULDs is used, then system complexity is reduced, but the time and efficiency of ULD handling operations deteriorates
Solution Approach 1:
The patent replaces manual mechanical tracking and routing operations with an automated electronic control system. The control tower uses computer algorithms to optimize ULD routing and allocation decisions, substituting human decision-making processes with automated computational systems. This mechanical-to-electronic substitution dramatically improves handling efficiency and speed while managing the complexity through structured software architectures and standardized communication protocols.
Solution Approach 2:
The system performs preliminary actions by pre-calculating optimal routes, pre-allocating ULDs to specific destinations, and pre-coordinating movements before actual operations begin. The control tower continuously plans and adjusts ULD routing in advance, anticipating future needs and optimizing sequences of operations. This preliminary planning approach maximizes productivity by eliminating delays and coordinating movements efficiently, while the automated nature of this planning manages system complexity through algorithmic processes.
3Loss of time
If autonomous control with real-time tracking is implemented, then ULD allocation and routing efficiency is improved, but the extent of automation and system complexity increases
Solution Approach 1:
The system implements continuous feedback loops where ULD sensors transmit real-time data (location, status, weight) to the control tower, which processes this information and sends back control commands. This closed-loop feedback system enables automated tracking and management of numerous ULDs, reducing the complexity of handling increased quantities while maintaining optimal allocation and movement coordination.
Solution Approach 2:
The autonomous control system is segmented into modular functional components: sensor modules on ULDs for data collection, communication modules for data transmission, a central control tower for decision-making, and execution modules for implementing commands. This segmentation allows the complex automated system to be built and managed as independent, manageable modules, reducing overall system complexity while maintaining high levels of automation and real-time tracking capabilities that minimize ULD empty time.

AI summary
An enhanced system and methods implement intelligent decision making autonomous control of Unit Load Devices (ULDs) within a prescribed airport perimeter, such as an airport. An Intelligent Autonomous ULD Control Tower (IAUCT) receives demands for ULDs, maintains a ULD repository data store, and controls ULDs within the prescribed airport perimeter. The IAUCT identifies at least a ULD state and a specific ULD position for the ULD within a prescribed airport perimeter, and stores the ULD state and specific ULD position in a ULD repository data store. The IAUCT selects a next action for the ULD based upon the demand for ULDs and based upon the ULD state and specific ULD position and the demand for ULDs within the perimeter area. The IAUCT dynamically identifies an optimized route for moving the ULD within the prescribed airport perimeter based upon the selected next action.
