Aircraft Cargo Hold Movable Plate for Rapid Center-of-Gravity Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the center of gravity in aircraft are inefficient and time-consuming, particularly when frequent changes in cargo and passengers require rapid balancing to ensure safe and efficient flight.
Innovation Solution
A device comprising a movable plate supported by air bearings and driven by actuators, allowing precise adjustment of the center of gravity by minimizing friction and enabling rapid repositioning within the cargo hold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cargo is redistributed to maintain center of gravity balance during multiple short-distance stops, then flight safety is improved, but time consumption increases significantly
Solution Approach 1:
The cargo hold floor is designed as a movable plate that can dynamically adjust its position along the longitudinal axis of the aircraft. This dynamic structure allows the cargo hold to automatically adapt to changing cargo distributions without requiring manual redistribution, thereby maintaining center of gravity balance while reducing time consumption during multiple short-distance stops
Solution Approach 2:
The movable plate system enables the cargo hold to self-adjust its configuration in response to cargo loading changes. By incorporating sensors and control mechanisms, the system automatically detects cargo weight and position changes, then autonomously repositions the movable plate to maintain proper center of gravity, eliminating the need for manual cargo redistribution and reducing operational time
2Measurement precision
If conventional cargo distribution methods are used, then center of gravity can be measured and adjusted, but the process is inefficient and cannot be completed in short periods
Solution Approach 1:
The patent replaces manual cargo redistribution with an automated movable plate system. Instead of physically moving cargo items to adjust center of gravity, the system uses a controlled movable floor that shifts the entire cargo load position electronically or mechanically, dramatically improving adjustment efficiency while maintaining measurement precision through integrated sensors
Solution Approach 2:
The movable plate serves multiple functions: it acts as the cargo hold floor, a positioning mechanism for cargo, and an automated center of gravity adjustment device. This multi-functional design eliminates the need for separate measurement and adjustment operations, thereby improving productivity while maintaining measurement accuracy
