Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated transportation systems face inefficiencies and stability issues due to the spatial integration of transportation facility control systems with transportation equipment, leading to reduced operational efficiency, increased resource utilization, and delayed response to failures.
Innovation Solution
Implementing an integrated control system that is spatially separated from transportation facilities, managed by virtualized hosts, and integrated with a Material Control System (MCS) and Real-Time Dispatcher (RTD) to manage multiple transportation facilities efficiently and stably, allowing for flexible expansion and rapid response to failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transportation facility control systems are spatially integrated with transportation equipment, then ease of operation is improved, but reliability deteriorates due to reduced operational efficiency and delayed response to failures
Solution Approach 1:
The system divides the control architecture into separate layers: the facility layer containing transportation equipment and the system layer containing the integrated control system. This segmentation allows each layer to operate independently while maintaining communication through standardized interfaces, thereby improving reliability without sacrificing ease of operation.
Solution Approach 2:
The patent transitions from spatial integration (co-locating control systems with equipment) to hierarchical integration (separating control functions into distinct layers connected through communication protocols). This dimensional shift from physical proximity to logical connectivity resolves the contradiction by maintaining operational ease through standardized interfaces while improving reliability through centralized monitoring and faster failure response.
2Reliability
If control systems are spatially separated from transportation facilities, then reliability is improved through centralized monitoring, but device complexity increases due to multiple layered components
Solution Approach 1:
The integrated control system in the system layer serves multiple functions simultaneously: it controls transportation facilities, monitors system status, manages databases, and handles real-time dispatching. This multi-functionality consolidates what would otherwise require separate systems, thereby improving reliability through centralized monitoring while minimizing the increase in device complexity.
Solution Approach 2:
The patent merges the Material Control System (MCS) and Real-Time Dispatcher (RTD) into a single integrated control system. This consolidation reduces the number of separate control systems needed, simplifying the overall architecture while maintaining reliable centralized monitoring and control of transportation facilities.
3Adaptability or versatility
If multiple control systems are established for multiple transportation facilities, then adaptability is improved, but device complexity increases due to multiple control systems and virtualized hosts
Solution Approach 1:
The patent employs virtualization technology where virtualized hosts create virtual copies of control system resources. This allows multiple transportation facilities to share common physical infrastructure while maintaining independent control instances, thereby achieving adaptability for different facility types without proportionally increasing physical device complexity.
Solution Approach 2:
The integrated control system is designed to handle multiple types of transportation facilities (AGV, OHT, stacker cranes, conveyors) through a unified architecture. This universal design provides adaptability across different facility types while avoiding the need for separate dedicated control systems for each facility type, thus limiting the increase in device complexity.
4Productivity
If integrated control system is established as a single server, then productivity is improved through efficient resource utilization, but reliability deteriorates due to single point of failure
Solution Approach 1:
The system segments the server infrastructure into multiple physical servers, each running virtualized hosts. This segmentation creates redundancy where multiple servers can handle control functions, eliminating the single point of failure while maintaining efficient resource utilization through virtualization. The integrated control system can migrate between servers, ensuring continuous operation and improved reliability.

AI summary
An automated transportation system includes a facility layer including at least one first transportation facility, and a system layer, in which an integrated control system controlling the at least one first transportation facility, a material control system (MCS) controlling a transport command with respect to the integrated control system, an application server managing a Real-Time Dispatcher (RTD), and a database storing information corresponding to an operation of the material control system and the real-time dispatcher are established. The facility layer and the system layer are spatially separated. Therefore, in the automated transportation system, the integrated server may be efficiently and stably operated, to quickly respond to a problem when a problem occurs in the system.
