Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The traditional approach of shipping products in pallets and disassembling them at multiple facilities is inefficient and labor-intensive, particularly for e-commerce models, requiring two separate stages of breakdown and not suitable for mixed pallets.

Innovation Solution

A warehouse system with robotic pickers and a conveyor system that dismantles pallets in a single stage, using robotic arms to remove individual units and assemble orders in customizable shipping cases, with automated case erection and liner insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If products are shipped in pallets and disassembled at multiple facilities, then shipping efficiency is maintained, but labor intensity increases and e-commerce fulfillment becomes unsuitable

Engineering Contradiction:

Improveshipping efficiencyVSAvoidlabor intensity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system segments the pallet into individual units using robotic pickers that automatically separate and handle each product unit, eliminating the need for manual disassembly at multiple facilities while maintaining shipping efficiency

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The robotic system performs self-service by automatically picking, sorting, and assembling individual units into new configurations without human intervention, reducing labor intensity while preserving productivity

Inventive Principle:

Principle #25Self-service

2Reliability

If traditional two-stage pallet breakdown is used, then standard shipping processes are maintained, but the process becomes inefficient for e-commerce and mixed pallets

Engineering Contradiction:

Improveprocess consistencyVSAvoidorder fulfillment efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary action by consolidating the pallet breakdown process into a single stage at the warehouse, preparing individual units in advance for various fulfillment scenarios including e-commerce and mixed pallets, thereby improving efficiency while maintaining process reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The robotic picker system provides multi-functionality by handling various pallet types and configurations in a single stage, accommodating both traditional and e-commerce fulfillment needs without requiring separate breakdown processes

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If manual pallet disassembly is performed at multiple facilities, then product distribution is achieved, but the process is not suitable for newer retail models like e-commerce

Engineering Contradiction:

Improveretail model compatibilityVSAvoidnumber of facilities

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system merges multiple facility functions into a single warehouse location by combining pallet breakdown, unit sorting, and order assembly operations in one automated system, enabling adaptability to various retail models while reducing the number of facilities needed

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The robotic system provides dynamic adaptability by being reconfigurable to handle different retail models and pallet types through software control, allowing the same physical system to serve multiple fulfillment scenarios without requiring additional facilities

Inventive Principle:

Principle #15Dynamics

AI summary

A warehouse system and method for fulfilling orders comprising a plurality of products. As pallets containing cases of individual units are received, they are transported to a specific storage location within a warehouse. There, a picker arm is configured to retrieve individual units from the pallets and place in a tote according to a specified order. The totes are transported through the warehouse to the specific storage locations, then sent to a packing station.
