Solution Overview

Problem

Existing automated storage and retrieval systems require manual processes for distributing stored goods to customer-accessible locations, which are time-consuming and costly, and pose safety risks due to the need for human intervention and mechanical handling.

Innovation Solution

Integrate a storage system with side-accessible storage columns that include a retractable top-access barrier and a side-access barrier, allowing customers to access goods directly from storage columns while preventing simultaneous access by lifting devices, ensuring safety and efficiency through a control system that manages barrier states based on lifting device presence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual processes are used for distributing stored goods to customer-accessible locations, then goods can be accessed, but the process is time-consuming and costly with safety risks

Engineering Contradiction:
Improvecustomer access to goodsVSAvoidtime for redistribution
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The storage column enables customers to directly access and retrieve goods from the storage location without requiring manual redistribution by staff. The self-service mechanism allows customers to open the barrier, take items, and close the barrier independently, eliminating the time-consuming manual process of transferring goods from storage to display areas.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention extracts the redistribution function from the automated storage system by providing direct customer access to the storage column. Instead of goods being moved from storage to separate display areas through manual handling, customers can directly access and remove goods from the storage column itself, eliminating the intermediate redistribution step.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If manual handling is used for goods distribution, then goods can be accessed, but safety risks increase due to human intervention

Engineering Contradiction:
Improvegoods accessVSAvoidsafety risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system enables customers to safely access goods through a controlled self-service mechanism. The barrier provides safety by preventing direct access to the storage column interior, while still allowing customers to retrieve items through a safe, standardized interface that eliminates risks associated with manual handling and direct access to moving parts.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The barrier acts as an intermediary between the customer and the storage column interior. It mediates the access process by providing a controlled interface that allows goods retrieval while maintaining safety boundaries, preventing customers from directly contacting potentially hazardous areas such as lifting device pathways.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If side-access is provided to storage columns, then customer access is enabled, but simultaneous access by lifting devices must be prevented

Engineering Contradiction:
Improvecustomer accessVSAvoidsafety coordination
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control system continuously monitors the state of the barrier and the position of lifting devices, and provides feedback control to prevent unsafe conditions. When the barrier is opened for customer access, the control system detects this state and prevents lifting devices from entering the storage column, ensuring safe coordination between customer access and automated operations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The barrier is designed to be dynamically controllable, changing its state based on real-time conditions. The barrier can be opened for customer access or closed to prevent access during lifting device operations, with the control system dynamically adjusting barrier state according to the current operational context to maintain safety while enabling functionality.

Inventive Principle:
Principle #15Dynamics

AI summary

A storage system (4) comprising one or more side-accessible storage columns (10), wherein each of the storage columns (io) comprises an access side (11), a side-access barrier (30, 30'), and a retractable top-access barrier (40, 40', 40"), wherein the side-access barrier (30, 30') is configured to allow access into the storage volume (ioV) from the access side (11) when open, and to prevent access into the storage volume (ioV) from the access side (11) when closed, and wherein the top-access barrier (40, 40', 40") is configured to be in an active state in which it is extended, and in an inactive state in which it is retracted, wherein the top-access barrier (40) is configured to prevent access of a lifting device (600) into the storage volume (ioV) from above when in active state, and to allow access of the lifting device (600) into the storage volume (ioV) from above when in inactive state, and wherein the top-access barrier (40, 40', 40") is configured so that, when the side-access barrier (30, 30') is able to be opened, the top-access barrier (40, 40', 40") is in the active state or the top-access barrier (40, 40', 40") is moved to the active state in response to opening the side-access barrier (30, 30').
