Solution Overview

Problem

Existing automated storage and retrieval systems face congestion issues around ports due to the limited number of ports, which impedes system operation and requires costly infrastructure expansions. Additionally, these systems struggle to efficiently utilize non-ideal storage facility spaces with varying ceiling heights and configurations.

Innovation Solution

The system comprises two vertically displaced track systems with parallel tracks forming a grid pattern, allowing for the use of a vehicle lift device to transfer vehicles between the track systems. This configuration enables efficient storage container handling and temporary storage, optimizing available space in storage facilities with non-ideal layouts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single track system is used for container handling vehicles, then the system structure is simple, but congestion occurs around ports limiting system operation

Engineering Contradiction:
Improvesystem operation efficiencyVSAvoidtrack system configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the single track system into multiple vertically displaced track systems (first track system and second track system). Each track system operates independently with its own container handling vehicles, allowing vehicles to be distributed across different levels and reducing congestion around ports. This segmentation resolves the contradiction by improving productivity through reduced congestion while accepting increased device complexity through the multi-level configuration.

Inventive Principle:
Principle #1Segmentation

2Productivity

If infrastructure is expanded to reduce port congestion, then system operation improves, but cost increases

Engineering Contradiction:
Improveport throughputVSAvoidinfrastructure expansion cost
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent introduces a vertical dimension by displacing track systems at different heights (first horizontal plane and second horizontal plane). This allows container handling vehicles to operate on multiple levels, distributing traffic and reducing port congestion without requiring horizontal infrastructure expansion. The vertical stacking approach improves port throughput while avoiding the high costs associated with expanding horizontal infrastructure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If storage facility space is optimized for ideal layouts, then storage capacity is maximized, but adaptability to non-ideal spaces is reduced

Engineering Contradiction:
Improvespace configuration flexibilityVSAvoidstorage capacity utilization
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent employs dynamically configurable track system arrangements that can adapt to different storage facility layouts. The vertically displaced track systems can be positioned and dimensioned to match non-ideal space configurations, allowing the system to utilize available storage capacity effectively regardless of the facility's original layout constraints. This dynamic adaptability resolves the contradiction by maintaining high storage capacity utilization while achieving flexibility in non-ideal spaces.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention concerns an automated storage and retrieval system, a storage facility and a method for operating such a system. The system comprises a first track system and a second track system, wherein a first horizontal plane P1 of the first track system and a second horizontal plane P2 of the second track system are arranged vertically displaced relative each other. The system comprises a vehicle lift device for transfer of at least one of the vehicles between the first track system and the second track system. The vehicle lift device comprises a support and transport platform arranged to carry the vehicle and a lift mechanism arranged to move the support and transport platform between:a first lift stop position LS1 establishing access between the support and transport platform and the first track system for enabling relocation of the vehicle between a support position on the support and transport platform and an operative position on the first track system,a second lift stop position LS2 establishing access between the support and transport platform and the second track system for enabling relocation of the vehicle between a support position on the support and transport platform and an operative position on the second track system.
