Aircraft Cargo Repositioning for In-Flight Balance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircrafts can become unbalanced during flight due to improperly loaded cargo or shifting cargo, leading to difficulty in control and potentially requiring cargo jettisoning to prevent crashes.
Innovation Solution
An apparatus with a mechanical interface, processors, and sensors that detect actuator inputs and states to dynamically adjust the position of cargo relative to the aircraft frame, balancing the center of gravity and maintaining flight control.

Engineering Contradiction Analysis
1Reliability
If cargo is loaded in an unbalanced fashion or shifts during flight, then the aircraft becomes unbalanced and difficult to control, but the cargo remains attached to the aircraft
Solution Approach 1:
The patent applies the dynamics principle by making the cargo position adjustable rather than fixed. The mechanical interface allows the cargo to be moved dynamically during flight to compensate for balance issues. The system detects actuator inputs and sensor outputs in real-time, determines appropriate cargo positioning procedures, and executes movements to maintain aircraft balance, transforming a static cargo arrangement into a dynamic balance-control system.
2Reliability
If the aircraft becomes severely unbalanced, then flight control is compromised, but the cargo remains attached creating harmful imbalance
Solution Approach 1:
The patent converts the harmful effect of attached cargo causing imbalance into a beneficial control mechanism. Instead of viewing the attached cargo as purely harmful, the system uses the cargo's presence and position as a control variable. By detecting actuator inputs and sensor outputs, the system determines procedures to reposition the cargo, transforming the potential harm into an opportunity for active balance management and preventing severe imbalance conditions.
Solution Approach 2:
The system implements feedback by continuously monitoring actuator inputs and sensor outputs that indicate aircraft state. This feedback loop allows the system to detect imbalance conditions, determine appropriate cargo repositioning procedures, and execute movements to correct the balance. The mechanical interface responds to these control signals, creating a closed-loop system that actively manages aircraft balance throughout flight.
3Reliability
If cargo is moved relative to the aircraft frame, then balance is improved, but the mechanical interface and control system complexity increases
Solution Approach 1:
The patent applies universality by designing the mechanical interface to perform multiple functions: it couples the cargo to the aircraft frame, enables position adjustment for balance control, and integrates with the aircraft's existing actuator and sensor systems. This multi-functional design reduces the need for separate dedicated balance control mechanisms, managing complexity through functional integration rather than adding independent systems.

AI summary
An apparatus includes: a mechanical interface configured to couple an object to a frame of an aircraft; one or more processors; and a computer readable medium storing instructions that, when executed by the one or more processors, cause the apparatus to perform functions that include: detecting a control input provided to an actuator of the aircraft and/or an output of a sensor that indicates a state of the actuator; determining, based on the control input provided to the actuator and/or the output of the sensor, a procedure for moving the object relative to the frame; and using the mechanical interface to perform the procedure.
