Automated Opportunistic Decant Picking for Order Fulfilment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inefficient order fulfillment processes in warehouses due to size constraints, inventory depletion, and sequencing conflicts, leading to delays and resource inefficiencies, particularly in decanting and downstream picking operations.
Innovation Solution
Implementing opportunistic picking during the decant process, utilizing automated storage and retrieval systems, and dynamic order groupings (dynamic bubbles) to optimize inventory replenishment and reduce labor requirements, with adaptive software managing resource allocation and order sequencing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional sequential order fulfillment processes are used, then process simplicity is maintained, but throughput efficiency is reduced and order fulfillment time increases
Solution Approach 1:
The system performs preliminary actions by pre-picking items during the decant process before orders are fully processed. Items are selected and prepared in advance at the decant workstation, then transferred to downstream systems, eliminating the need for separate downstream picking operations and improving overall throughput efficiency.
Solution Approach 2:
The invention merges the decant process with the picking process by allowing operators to perform both functions at the same workstation. The decant workstation is configured to handle both incoming inventory decanting and order item picking simultaneously, reducing the number of separate processes and improving efficiency.
2Ease of operation
If downstream picking operations are implemented, then order fulfillment flexibility is improved, but labor requirements and facility space increase
Solution Approach 1:
The decant workstation is designed to be self-sufficient by performing both decanting and picking functions. The system automatically determines which items to pick during decanting based on pre-assigned orders, reducing the need for separate downstream picking operations and minimizing additional labor requirements.
Solution Approach 2:
The decant workstation is configured with multi-functionality to perform both decanting incoming inventory and picking items for orders. This universal workstation eliminates the need for dedicated downstream picking stations, reducing facility space requirements while maintaining order fulfillment flexibility.
3Reliability
If items are decanted into inventory storage first, then inventory availability is improved, but order fulfillment time increases due to waiting
Solution Approach 1:
The system performs preliminary picking actions during the decant process itself, before items are fully integrated into inventory storage. This allows order items to be selected and prepared in advance, then transferred directly to customers without waiting for separate downstream picking operations, reducing fulfillment time while maintaining inventory availability.
Solution Approach 2:
The decant process continues seamlessly into the picking process without interruption. Items are decanted and immediately available for picking from the same workstation, eliminating idle waiting time between decanting and picking operations. The continuous flow of items through the decant workstation maintains both inventory availability and fast fulfillment speed.

AI summary
A method and system for opportunistically picking order items during decant processes. An order management system determines which items required for a pending order are depleted within a decant function or storage system and orders replenishment, such as inbound vendor cases containing the depleted required items, to the decant function. Operators at decant workstations pick the required items from the inbound vendor cases into order containers while simultaneously decanting any remaining, non-required vendor items into inventory containers. The order containers and the inventory items are stored in a storage system until all required items for an order are present therein. Once all required items are present, the items are released to a downstream picking workstation, sorter, and/or packing station. The method with opportunistic decant may enable minimized facility space requirements, labor reductions, and resource reductions while improving facility throughput.
