Carriage Allocation by Destination Area for Faster Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing conveyance systems, such as those described in Patent Literature 1, lack efficiency in conveying multiple targets due to unspecified departure and destination places, leading to suboptimal allocation and movement of conveyance targets across divided regions.
Innovation Solution
A conveyance system with a control device that allocates conveyance targets to carriages based on acquired departure and destination information, ensuring that destinations within the same region are allocated to the same carriage, thereby optimizing the movement across and within bays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a carriage conveys multiple conveyance targets individually without considering destination areas, then the carriage can transport various targets, but the conveyance efficiency decreases due to unnecessary movements across different areas
Solution Approach 1:
The control device performs preliminary allocation of conveyance targets to carriages based on destination area information before actual conveyance begins. This ensures that carriages are assigned targets within the same area group, preventing unnecessary inter-area movements and optimizing the conveyance route from the outset
Solution Approach 2:
The system changes the allocation parameter from individual target assignment to area-based batch assignment. By grouping targets by their destination areas and allocating them together to the same carriage, the system reduces the number of trips required and eliminates redundant movements across area boundaries
2Adaptability or versatility
If the carriage travels to multiple different destination areas, then it can deliver diverse targets, but the movement distance and time increase
Solution Approach 1:
The movable region is segmented into multiple areas, and the allocation process ensures that each carriage is assigned targets whose destinations fall within the same segmented area. This segmentation strategy allows the system to maintain high-speed conveyance within areas while still providing comprehensive coverage across all areas through coordinated carriage deployment

AI summary
In order to efficiently convey a conveyance target, a conveyance system includes: a carriage configured to be capable of conveying a plurality of conveyance targets; and a carriage controller configured to perform an allocation process of allocating, to the carriage, a conveyance target to be conveyed, the carriage controller performing the allocation process such that, in a case where a region in which the carriage is movable is divided into a plurality of areas, areas of destinations of the plurality of conveyance targets that are to be simultaneously conveyed by the carriage are the same.
