Solution Overview

Problem

Existing storage systems face challenges in achieving high material throughput while minimizing space requirements, particularly in high-bay warehouses where throughput capacity is limited and area storage systems require significant space.

Innovation Solution

A hybrid storage system combining area storage with high-bay storage, where continuous conveyors and movable storage and retrieval devices facilitate the transfer of goods between storage lines and high-bay shelves, allowing for efficient loading, unloading, and rearrangement of goods across multiple levels to optimize space usage and throughput.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If high-bay warehouse with storage and retrieval device is used, then storage capacity per floor space is improved, but material throughput capacity deteriorates

Engineering Contradiction:
Improvefloor spaceVSAvoidmaterial throughput
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The storage system is divided into multiple independent storage levels (first level, second level, third level) that can operate semi-independently. Each level has its own storage lines and can handle material flow separately, allowing parallel operations that increase overall throughput while maintaining high vertical space utilization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from traditional two-dimensional floor-based storage to three-dimensional vertical storage by stacking multiple storage levels one above another. This enables the system to exploit vertical space for high storage density while using multiple levels to parallelize material flow and increase throughput capacity.

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

2Productivity

If area storage system with multiple storage lines is used, then material throughput is improved, but space requirement deteriorates

Engineering Contradiction:
Improvematerial throughputVSAvoidspace requirement
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

Instead of expanding area storage horizontally with more storage lines, the system stacks storage lines vertically across multiple levels. The first level, second level, and third level each contain storage lines, but they are arranged vertically rather than horizontally, reducing the floor space footprint while maintaining high throughput capability.

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

Solution Approach 2:

Multiple storage lines from different levels (first level, second level, third level) are merged into a unified system that shares common loading devices and retrieval devices. This consolidation allows the system to achieve high throughput through parallel processing across levels while minimizing the total space required compared to having separate systems.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If storage lines are interrupted for transfer car access, then product distribution between storage lines is improved, but space requirement and structure complexity deteriorates

Engineering Contradiction:
Improveproduct distributionVSAvoidspace requirement
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Loading devices and retrieval devices serve as intermediary elements that can access storage lines from the aisle without requiring interruptions in the storage line structure. These intermediaries enable product distribution between different storage lines and levels while maintaining continuous storage lines, thus avoiding the need for physical interruptions that would increase space requirements and structural complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
