Solution Overview

Problem

Existing AGV systems for transporting shelves in warehouses are inefficient in managing multiple tasks with varying priorities and require better utilization of buffer storage spaces to enhance operational efficiency.

Innovation Solution

A method and apparatus that utilize buffer storage spaces to decompose transporting routes into sections, allowing automated guided vehicles to manage tasks with varying priorities and optimize their use by selecting idle vehicles and managing buffer storage space allocation based on task priorities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If AGV systems transport shelves directly from storage to picking stations without buffer storage spaces, then the transportation process is simple, but the system cannot efficiently manage multiple tasks with varying priorities and vehicle utilization is low

Engineering Contradiction:
Improveshelf transportation efficiencyVSAvoidtransportation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The transportation route is decomposed into multiple sections by introducing buffer storage spaces between shelf storage and picking stations. This segmentation allows the system to break down complex transportation tasks into manageable segments, enabling priority-based task management and improving overall transportation efficiency without overwhelming the AGV system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Buffer storage spaces are introduced as intermediary zones between shelf storage and picking stations. These buffer zones act as mediators that temporarily hold shelves, allowing the system to decouple the transportation process from immediate picking demands. This enables better task prioritization and AGV utilization by allowing shelves to wait in buffers rather than requiring immediate direct transport.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If AGV systems use direct point-to-point transportation without buffer storage, then the system structure is simple, but task completion flexibility and hit rate are reduced

Engineering Contradiction:

Solution Approach 1:

The transportation route is decomposed into multiple sections by introducing buffer storage spaces between shelf storage and picking stations. This segmentation allows the system to break down complex transportation tasks into manageable segments, enabling priority-based task management and improving overall transportation efficiency without overwhelming the AGV system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Shelves are transported to buffer storage spaces in advance before actual picking operations. This preliminary action allows the system to prepare shelves ahead of time and store them in buffers, enabling flexible task prioritization and ensuring that shelves are ready when needed without requiring immediate direct transport to picking stations.

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If AGV systems prioritize urgent tasks dynamically, then task completion efficiency improves, but the control system complexity increases

Engineering Contradiction:
Improvetask completion timeVSAvoidpriority management system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

Shelves are transported to buffer storage spaces in advance before actual picking operations. This preliminary action allows the system to prepare shelves ahead of time and store them in buffers, enabling flexible task prioritization and ensuring that shelves are ready when needed without requiring immediate direct transport to picking stations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements dynamic priority management by monitoring task urgency and adjusting transportation priorities in real-time. When urgent tasks are detected, the system provides feedback to re prioritize AGV assignments and route planning, ensuring that time-sensitive operations receive immediate attention while maintaining overall system efficiency.

Inventive Principle:
Principle #23Feedback

AI summary

A method and apparatus for carrying a shelf. One specific implementation of the method comprises: receiving first task information from a task server (104); determining, according to an identifier of a shelf to be carried, the position of a shelf storage location (201) for storing the shelf as a starting point position; determining, according to an identifier of a first picking station, the position of a first temporary storage location in a temporary storage location set corresponding to the first picking station as an ending point position; generating first carrying information according to the determined starting point position and ending point position; and sending the first carrying information to automated guided vehicles (106,107), so that the automated guided vehicles (106, 107) carry the shelf. According to the implementation, the automated guided vehicles (106,107) can be used more fully.
