Carriage System Dynamic Route Selection via Real-Time Congestion Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carriage systems in semiconductor and liquid crystal display manufacturing plants do not effectively determine congestion statuses among multiple running routes, leading to inefficient route selection and increased transit times.
Innovation Solution
A carriage system equipped with running status reporting means and a controller that generates and transmits congestion information, allowing each carriage to re-search and choose a route based on real-time congestion levels, thereby optimizing route selection to avoid congested paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple running routes are provided to increase conveyance flexibility, then adaptability is improved, but route selection efficiency deteriorates due to inability to determine congestion status
Solution Approach 1:
The system implements feedback mechanisms where carriages report their running status and speed to the controller. The controller aggregates this information to generate real-time congestion data for each route section, which is then fed back to carriages to enable dynamic route selection based on current system state
Solution Approach 2:
Each carriage is equipped with autonomous route re-searching capability that allows it to independently determine optimal routes based on received congestion information, eliminating the need for centralized route assignment and enabling self-optimized conveyance
2Speed
If real-time congestion monitoring is implemented to improve route selection, then conveyance speed is improved, but system complexity increases due to additional reporting and control mechanisms
Solution Approach 1:
The controller serves as an intermediary that simplifies the system architecture by centralizing congestion information aggregation and processing. Instead of complex peer-to-peer communication between carriages, the controller mediates information flow, collecting status reports and distributing congestion data to enable coordinated route optimization
Solution Approach 2:
The controller performs multiple functions including receiving running status reports from carriages, generating congestion information, transmitting route guidance to carriages, and coordinating overall system operation, thereby reducing the need for separate dedicated components for each function

AI summary
The present invention provides a carriage system which, to choose one of a plurality of running routes, can appropriately determine the congestion statuses of the running routes to choose one of them along which a carriage can reach its destination earliest. In a carriage system 10, each carriage 1 is provided with running status reporting means 1b for reporting a running status based on a running speed to a zone controller 3. The zone controller 3 is provided with congestion information generating means 3b for generating congestion information by putting together reports from the running status reporting means 1b of the carriages 1.
