Shared-Sensing Route Planning for Article Transport Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article transport facilities face inefficiencies in route determination due to changing environmental conditions, as movable bodies rely solely on static map information, leading to suboptimal route planning.
Innovation Solution
Implement a system where movable bodies include surrounding detection devices to acquire real-time information, share this information through a communication system, and utilize shared data to refine route determination, considering dynamic changes in the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If movable bodies rely solely on static map information for route determination, then the system structure remains simple, but the route planning becomes suboptimal due to changing environmental conditions
Solution Approach 1:
The patent transforms the static route determination system into a dynamic one by enabling movable bodies to acquire real-time surrounding information through surrounding detection devices and update routes based on current environmental conditions. This allows the system to adapt to changing states hourly or in real-time, improving moving efficiency while managing complexity through distributed intelligence.
Solution Approach 2:
The patent implements feedback mechanisms where movable bodies continuously detect surrounding information and feed it back to the route determination process. The route determination section uses this feedback to search for optimized routes based on current conditions, creating a closed-loop system that improves productivity through adaptive decision-making.
2Measurement precision
If movable bodies use only map information for route search, then the device complexity is low, but the route determination precision deteriorates due to environmental changes
Solution Approach 1:
The patent merges multiple information sources (map information from storage sections and real-time surrounding information from detection devices) to create a comprehensive basis for route determination. This combination allows the route determination section to achieve high precision by considering both static map data and dynamic environmental conditions simultaneously.
Solution Approach 2:
The patent introduces an information sharing process as an intermediary mechanism that collects surrounding information from multiple movable bodies and makes it available to all participants. This mediator layer enables precise route determination without requiring each movable body to have complex individual detection capabilities, as they can rely on shared information from the network.
3Productivity
If each movable body determines routes independently using only its own map information, then the system operates autonomously, but the overall moving efficiency of the facility deteriorates
Solution Approach 1:
The patent creates a universal information sharing infrastructure that serves all movable bodies in the facility. The communication system enables each movable body to access surrounding information not only from its own sensors but also from other movable bodies, making the information system multi-functional and facility-wide rather than individual-specific.
Solution Approach 2:
The patent ensures continuous acquisition and sharing of surrounding information through the communication system, allowing movable bodies to maintain up-to-date knowledge of environmental conditions. This continuous information flow enables ongoing optimization of routes and maintains high overall moving efficiency throughout the facility's operation.

AI summary
An article transport facility includes a plurality of movable bodies each configured to move in a movable area. Each of the movable bodies includes a surrounding detection device; and a surrounding information acquisition section configured to acquire surrounding information based on a detection result from the surrounding detection device. A plurality of movable bodies in a predetermined sharing range performs an information sharing process of sharing respective pieces of surrounding information acquired by the plurality of movable bodies. Each of the movable bodies searches for a routes to its destination based on the pieces of surrounding information shared in the information sharing process.
