AGV Baggage Storage Rack Coordination for Parallel Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baggage storage systems often require human intervention for storage and retrieval, which can be inefficient and limited in capacity, as seen in systems like the ABB robotics 'Yobot' which has size and capacity constraints.
Innovation Solution
An automated baggage management system that includes a storage rack with vertical columns and horizontal rails, a baggage transportation system using automated guided vehicles (AGVs) with controllers and wireless communication, and a baggage administration server that coordinates the movement of AGVs for efficient storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated guided vehicles (AGVs) are used for baggage transport, then productivity and speed are improved, but device complexity increases
Solution Approach 1:
The system is divided into independent functional modules: multiple AGVs for transport, vertical columns for storage, horizontal rails for movement, and a central server for coordination. Each AGV operates independently with its own controller, allowing parallel baggage handling operations that increase productivity while keeping individual components manageable in complexity
Solution Approach 2:
The AGVs are designed as multi-functional units that can perform multiple operations: transporting baggage horizontally along rails, transferring to elevators for vertical movement, and interfacing with the central management server. This universality allows a single system architecture to handle various baggage management tasks, improving productivity without proportionally increasing overall system complexity
2Quantity of substance
If multiple AGVs operate simultaneously, then capacity and simultaneous handling are improved, but coordination complexity increases
Solution Approach 1:
The central server receives real-time status information from all AGVs and continuously monitors their positions and states. Based on this feedback, the server dynamically assigns new tasks to available AGVs and adjusts coordination in real-time, enabling multiple AGVs to operate simultaneously without collisions or conflicts, thus increasing capacity while managing coordination through centralized intelligence
Solution Approach 2:
The central server acts as an intermediary between multiple AGVs, receiving requests from user interfaces and translating them into coordinated commands for appropriate AGVs. This mediator approach allows the system to handle multiple baggage items simultaneously by intelligently distributing tasks across available AGVs, increasing throughput while abstracting the coordination complexity into a centralized management layer

AI summary
A baggage management system includes: a storage rack including a plurality of receptacles shaped and structured to retain one or more baggage items; a baggage transportation system including a plurality of automated guided vehicles (AGVs) configured to transport one or more baggage items between a pick up point, a drop off point, and the storage rack, each AGV including a a wireless communication unit and a controller configured to control movement of the specific AGV based on received control instructions; and a baggage administration server including a processor, a memory unit, and a wireless communication interface, and configured to receive a request to store or retrieve a baggage item from the storage rack, determine the position of the one or more AGVs, identify the one or more AGVs required to either store or retrieve a baggage item as defined in the request, and transmit control instructions to the AGVs.
