Package Sorting Logical Partitioning and Path Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing package sorting robot systems face inefficiencies in energy consumption and sorting efficiency due to the long distances traveled by transporting devices, which are not optimized for minimizing delivery paths and accommodating multiple road directions.
Innovation Solution
The sorting area is divided into logical partitions with designated item collecting and dropping areas, and a path optimization method is implemented to map containers with short delivery distances to high-probability road directions, using mobile transporting devices and transferring devices with height adjustment capabilities to automate item delivery and reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the sorting area is divided into logical partitions with item collecting and dropping areas, then the delivery path distance is reduced, but the device complexity increases
Solution Approach 1:
The sorting area is divided into multiple logical partitions, each containing item collecting areas and item dropping areas. This segmentation allows transporting devices to operate within smaller, defined regions, reducing the overall delivery path distance and energy consumption while maintaining system functionality through modular organization.
2Loss of energy
If path optimization is implemented to map containers with short delivery distances to high-probability road directions, then the delivery path is optimized, but the device complexity increases
Solution Approach 1:
The system pre-establishes mapping relationships between containers and road directions based on delivery distance and probability. This preliminary configuration allows the control system to make optimized routing decisions without complex real-time calculations, reducing energy consumption while keeping control complexity manageable through pre-computed optimization data.
3Productivity
If mobile transporting devices are used to deliver items within logical partitions, then the delivery path distance is reduced, but the device complexity increases
Solution Approach 1:
Mobile transporting devices are deployed within each logical partition to dynamically deliver items to dropping areas. This dynamic approach allows flexible routing and adaptive response to varying delivery demands, improving sorting efficiency while the mobility aspect manages the complexity through flexible rather than rigid fixed-path solutions.

AI summary
Provided is a package sorting method, a sorting area layout, a sorting system, and a path optimization method. The package sorting method includes: dividing a sorting area into at least a first logical partition close to a first item collecting area and a second logical partition close to a second item collecting area, where the first logical partition includes a first item dropping area, and the second logical partition includes a second item dropping area. By this method, a total path of package delivery is reduced.
