Solution Overview

Problem

Existing grid storage systems do not adequately address the risk of fire damage to warehouses, despite their efficient space utilization.

Innovation Solution

The system is divided into sub-grids separated by fire walls with aisles and bridges, equipped with closable fire doors to contain fires within manageable sections, allowing bin handling vehicles to traverse between sub-grids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the grid storage system is divided into sub-grids separated by fire walls with closable fire doors, then fire containment capability is improved, but device complexity increases

Engineering Contradiction:

Improvefire containment capabilityVSAvoidsystem structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The grid storage system is divided into multiple sub-grids by fire walls that extend from the top surface to the bottom surface of the grid structure. Each sub-grid can be independently isolated using closable fire doors positioned at the grid openings, allowing fire containment in one section without affecting other sections. This segmentation approach directly improves fire containment capability while maintaining operational flexibility.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If fire walls are installed to separate sub-grids, then fire damage risk is reduced, but space utilization decreases

Engineering Contradiction:

Improvefire damage riskVSAvoidstorage space availability

Core Design Contradiction:

Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

Fire walls are positioned to extend vertically from the top surface to the bottom surface of the grid structure, utilizing the vertical dimension to create fire separation. This allows fire containment without significantly reducing the horizontal storage area available for bins, as the separation occurs in the vertical dimension rather than consuming horizontal storage space.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If closable fire doors are positioned at grid openings, then fire spread is prevented, but bin handling operations become more complex

Engineering Contradiction:

Improvefire spread preventionVSAvoidbin handling operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Fire doors are designed with closable mechanisms that allow them to be opened during normal bin handling operations to maintain operational flow, and automatically or manually closed when fire risk is detected. This dynamic operation enables the system to adapt between operational mode (doors open) and safety mode (doors closed), preventing fire spread while minimizing impact on bin handling efficiency.

Inventive Principle:

Principle #15Dynamics

AI summary

An autonomous grid storage system (1) arranged in a warehouse space (12). The autonomous grid storage system is divided within the warehouse space, for example on a single floor of said space, into a plurality of sub grids (10a/10b) separated by fire walls (18). One or more bridges (14) pass through openings in the fire wall to allow bin handling vehicles (210/301) to traverse between the sub grids. The openings (20) are provided with closable fire door (22).
