Protected Picking Station Layout for Multi-Shelf Worker Safety

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems for moving storage shelves to a picking station in a warehouse pose safety risks to workers performing picking work due to the transportation of multiple shelves, which can compromise worker safety.

Innovation Solution

A picking station unit is designed with a stage, upward-extending pillars, and lateral arms that provide a safe boarding area for workers, along with a mechanism for easy movement and communication features to enhance safety and efficiency.

Engineering Contradictions & Design Principles

1Productivity

If multiple storage shelves are transported to the picking station, then the productivity of the picking operation is improved, but the safety of the worker deteriorates

Engineering Contradiction:

Improvepicking operation efficiencyVSAvoidworker safety risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The picking station is segmented into distinct functional zones: a protected boarding area bounded by pillars and arms, and an open working area for shelf manipulation. This segmentation creates physical separation between the worker's safe zone and the hazardous shelf handling zone, allowing multiple shelves to be present without compromising worker safety.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pillar and arm structure acts as an intermediary protective barrier between the worker and the stored shelves. This intermediate structure defines a protected space that mediates between the worker's need for safety and the system's need to handle multiple shelves efficiently.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a protective structure is added to the picking station, then the safety of the worker is improved, but the device complexity increases

Engineering Contradiction:

Improveworker safetyVSAvoidpicking station structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective structure is merged with the functional elements of the picking station. The pillars serve both structural support and safety boundary functions, while the arms provide both structural framing and protective barrier functions. This merging eliminates the need for separate protective elements, reducing overall complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The pillar and arm structure performs multiple functions simultaneously: structural support, definition of protected space, physical barrier against shelves, and visual guidance for workers. This multi-functionality reduces the need for additional dedicated safety components, thereby limiting complexity increase.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A picking station unit includes a stage where a worker boards; a pillar located at an end portion of the stage and extending upward from the stage; and an arm extending laterally from the pillar along a boundary portion between an area of the stage and an area outside the stage.
