Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static, prediction-driven operations are used in sorting terminals, then operational simplicity is maintained, but productivity and adaptability deteriorate due to inaccurate payload estimation and sub-optimal configurations
Solution Approach 1:
The patent transforms static, prediction-driven operations into dynamic, real-time adaptive operations. The system continuously adjusts sorting terminal configurations, payload estimates, and resource allocations based on real-time data from multiple sources, enabling the system to adapt to changing conditions while maintaining operational simplicity through automated decision-making.
Solution Approach 2:
The patent implements comprehensive feedback mechanisms by collecting real-time data from various sources including package scanners, weight sensors, and operational systems. This feedback is processed to continuously refine payload estimates and optimize terminal configurations, creating a closed-loop system that improves productivity while maintaining ease of operation through automated adjustments.
2Measurement precision
If expert managers make manual interventions to improve payload accuracy, then measurement precision may improve, but device complexity and time consumption increase due to multiple interventions and decision-making burdens
Solution Approach 1:
The patent enables the system to self-correct payload estimation errors through automated algorithms that process real-time data and adjust configurations without human intervention. The system performs self-optimization by automatically refining payload estimates and adjusting terminal operations, eliminating the need for expert managers to make manual interventions while maintaining high measurement precision.
Solution Approach 2:
The patent replaces manual expert decision-making with automated computational systems. Machine learning algorithms and real-time data processing systems substitute for human experts, automatically making decisions about payload estimation and terminal configurations. This substitution reduces system complexity by automating previously manual processes while maintaining or improving measurement precision.
3Measurement precision
If multiple interventions are implemented to correct payload estimation errors, then measurement precision improves, but loss of time increases due to fatigue-induced errors and repeated corrections
Solution Approach 1:
The patent performs preliminary actions by continuously refining payload estimates using real-time data before operational decisions are made. The system proactively adjusts configurations and predictions in advance, preventing the need for repeated corrections later. This preliminary optimization reduces both the need for interventions and the time lost to corrections by maintaining accurate estimates throughout operations.
4Productivity
If real-time adaptive optimization is implemented using digital twins, then productivity improves, but device complexity increases due to sophisticated cyber-physical systems and multiple data sources
Solution Approach 1:
The patent uses digital twins as virtual copies of the physical sorting terminal to perform simulations and optimizations without affecting actual operations. The digital twin replicates the terminal's behavior and allows testing of different configurations and interventions in a virtual environment, enabling productivity improvements while managing complexity by isolating the sophisticated systems from the physical infrastructure.

AI summary
This disclosure relates generally to the method and system for dynamically optimizing the operations of logistics management system. The existing methods for optimizing the operational processes in the sorting terminals are not dynamic as the sorting terminal operations are largely manual and experience driven. The proposed method and system describe an actor-based representation of simulatable digital twin of the sorting terminal that enables in-silico quantitative exploration of design space to help human experts arrive at the right decisions related to the logistics management system. The proposed method and system initially construct a high-fidelity simulatable digital twin of the sorting terminal, validate it, set it up with real data, and simulate various adaptation and design alternatives to understand their impacts on the key performance indicator values.
