Engineering Contradiction Analysis
1Measurement precision
If manual weight and balance calculation methods are used, then simplicity and ease of operation are maintained, but accuracy and real-time feedback capability deteriorate
Solution Approach 1:
The patent replaces manual mechanical calculation methods with an automated computer-based system that performs weight and balance calculations electronically. The system uses processors to automatically compute load distribution data, center of gravity positions, and provide real-time feedback, eliminating the need for manual calculations while improving accuracy.
Solution Approach 2:
The system enables automatic self-calculation of weight and balance parameters by the aircraft loading system itself. The processor automatically determines load distribution, updates center of gravity positions, and generates feedback without requiring external manual intervention, making the system self-sufficient in maintaining accurate weight and balance records.
2Reliability
If real-time load distribution monitoring is implemented, then flight safety and stability are improved, but system complexity and data processing requirements increase
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors cargo loading, automatically recalculates load distribution data and center of gravity positions, and provides real-time feedback to operators. This closed-loop feedback system ensures flight safety by immediately alerting operators to any weight and balance violations and suggesting corrective loading actions.
Solution Approach 2:
The cargo loading system is divided into multiple zones with individual weight tracking. The patent segments the cargo area into distinct zones, each monitored separately, allowing granular control over load distribution. This segmentation simplifies the monitoring complexity by breaking down the overall weight and balance problem into manageable zone-level calculations.
3Productivity
If dynamic load distribution recommendations are provided, then loading efficiency and productivity are enhanced, but computational requirements and processing time increase
Solution Approach 1:
The system performs preliminary calculations of optimal load distribution before actual cargo loading begins. By pre-computing recommended weight allocations for different zones based on the total cargo weight and desired center of gravity position, the system enables operators to efficiently load cargo without requiring complex real-time calculations during the loading process itself, thus improving productivity while managing computational energy consumption.
