Automated Picking Station Order Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current order fulfillment systems are labor-intensive and prone to errors due to the need for multiple 'touches' of inventory items, which increases labor costs and the risk of errors in processing and shipping, especially when handling a large number of small orders with varying physical characteristics.
Innovation Solution
An automated system that uses a computerized method to manage inventory receptacles and assign orders to pick stations, allowing for reduced 'touches' of items by consolidating orders and using a network of inventory receptacles with compartments to streamline the picking and packing process, with the ability to prioritize orders and group them for efficient processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple individual picking receptacles are used for each order portion, then order fulfillment can be achieved, but the number of handling touches increases and labor costs increase
Solution Approach 1:
The patent combines multiple order portions into a single mixed picking receptacle. Instead of using separate receptacles for each order portion, the system allows one receptacle to contain items from multiple different orders, thereby reducing the total number of receptacles needed and minimizing handling touches while maintaining order fulfillment capability
Solution Approach 2:
The picking receptacle is designed to serve multiple functions: it can hold items for a single order or multiple orders simultaneously. This universal receptacle design allows the same physical container to adapt to different picking scenarios, reducing the need for specialized receptacles for each order and decreasing overall system complexity
2Productivity
If inventory warehouse is divided into geographic portions for individual pickers, then picking efficiency is improved, but the warehouse footprint must be very large to accommodate many SKU's
Solution Approach 1:
The system dynamically assigns order portions to pickers based on current workload and receptacle contents rather than assigning fixed geographic zones. This dynamic allocation allows flexible distribution of picking tasks across the warehouse footprint, maintaining picker efficiency while optimizing space utilization without requiring rigid geographic divisions
Solution Approach 2:
The computer system acts as an intermediary that coordinates between multiple pickers and the centralized inventory storage. It manages the distribution of mixed picking receptacles to different pickers, enabling efficient collaboration across the warehouse without requiring each picker to have dedicated geographic zones, thus reducing overall footprint
3Productivity
If multiple receptacles are used for orders with multiple items, then complete order fulfillment is achieved, but subsequent sorting and processing time increases
Solution Approach 1:
The system performs preliminary consolidation of items for multiple orders into mixed picking receptacles during the picking phase itself. By pre-organizing items destined for different orders into single receptacles during picking, the system eliminates or reduces the need for subsequent sorting operations, thereby completing orders efficiently without adding processing time

AI summary
A method of filling orders and order fulfillment system includes storing inventory receptacles in an automated warehouse, some having a plurality of different types of inventory items. A queue of orders is maintained in a computer system, each including at least one inventory item. Each order is selected from the queue and assigned to a pick station. The computer system retrieves inventory receptacle(s) from the automated warehouse for the selected order and supplies the receptacle(s) to the pick station. The computer system identifies to an operator which inventory item is to be segregated with the selected order in at least one put receptacle. One or more of the put receptacles receives inventory items for at least one individual order and is directed to a secondary order processing station where items are separated into individual orders. The operator may be provided the capability to consolidate inventory items from inventory receptacles while picking orders to consolidate partially filled inventory receptacles in a consolidated inventory receptacle.
