Solution Overview

Problem

Existing automated storage and retrieval systems struggle to accommodate a diverse range of items efficiently, leading to increased complexity, space inefficiency, and longer retrieval times due to the need for separate processes for in-grid and off-grid storage of items with varying sizes and shapes.

Innovation Solution

The introduction of a container design that allows for vertically discriminating storage through the use of racks and side-access doors, enabling the storage of items at different heights within the container, which can be stacked in a column, and facilitating easier and quicker retrieval without damaging the items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If all containers are made the same size and shape to enable automation and efficiency, then the automated storage and retrieval system operates efficiently, but space is wasted inside containers storing smaller goods and the system cannot accommodate items with special storage requirements

Engineering Contradiction:
Improveautomation efficiencyVSAvoidaccommodation of diverse items
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The container is divided into multiple compartments separated by partition walls. Each compartment can independently store different items, allowing the container to accommodate diverse items with varying sizes and shapes while maintaining the standardized external dimensions needed for automated handling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized container design with internal partitions serves multiple functions: it maintains uniform external dimensions for automated robot handling while internally providing customized storage spaces for diverse items including bulky goods, heavy items, and items requiring special positioning, eliminating the need for separate off-grid storage.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If bulky, heavy or irregularly shaped goods are accommodated by making containers particularly large, then these items can be stored, but space is wasted in containers storing smaller goods

Engineering Contradiction:
Improveaccommodation of bulky itemsVSAvoidcontainer space utilization
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The container is divided into multiple compartments separated by partition walls. Each compartment can be optimized for specific item types (e.g., one compartment for bulky items, another for smaller goods), allowing efficient space utilization across all containers while maintaining the ability to accommodate diverse item sizes.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If items are stored in typical containers without internal structures, then the system is simple, but it is difficult to retrieve an individual item from a plurality of items stored within these containers

Engineering Contradiction:
Improvecontainer structureVSAvoiditem retrieval
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The container is divided into multiple compartments that physically separate different items or groups of items. This segmentation allows the robotic system to retrieve specific items by accessing only the relevant compartment, significantly improving retrieval efficiency compared to searching through a single undivided space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition walls act as intermediaries that organize items within the container. This intermediate structure enables the robotic retrieval system to efficiently locate and access specific items without having to search the entire container volume, improving operation ease while maintaining relatively simple container construction.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If large, bulky or otherwise unwieldy items are stored outside the storage grid, then these items can be accommodated, but additional complexity is introduced requiring at least two separate retrieval processes

Engineering Contradiction:
Improveaccommodation of diverse itemsVSAvoidretrieval process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container integrates multiple storage compartments for different item types (including bulky items) into a single standardized unit that can be handled by the automated retrieval system. This merging of previously separate storage locations (in-grid and off-grid) into one container allows all items to be retrieved through the same automated process, eliminating the need for multiple retrieval systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The standardized container serves as a universal storage unit that can accommodate diverse items including bulky goods through internal partitions. This multi-functional container design eliminates the need for separate off-grid storage areas and their associated retrieval processes, simplifying the overall system to a single unified retrieval operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)
