Automated Order Dispensing System with Mobile Robot Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional order fulfillment systems in supply chains face inefficiencies in processing and dispensing orders, particularly in managing totes and containers, which can lead to increased fulfillment time and resource utilization.
Innovation Solution
An automated or semi-automated order fulfillment system that utilizes mobile robots to transfer totes between storage structures and workstations, allowing for staged container placement near customer pickup locations, enabling faster order fulfillment and efficient resource management through multi-level asynchronous dispensing and buffering arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional systems transfer totes using mobile robots between storage structure and picking workstations, then order fulfillment is achieved, but fulfillment time and resource utilization increase
Solution Approach 1:
The system stages containers locally at dispensing locations in advance of customer pickup. Mobile robots deliver containers from storage structures to dispensing locations before they are needed, so that when customers arrive, their orders are already prepared and immediately available for pickup, eliminating waiting time
Solution Approach 2:
The patent introduces dispensing locations as intermediary structures between storage and customer pickup points. These locations act as buffer zones where containers are pre-positioned, decoupling the storage retrieval process from the customer pickup process and enabling parallel operations that reduce overall fulfillment time
2Ease of operation
If conventional systems use sequential picking from inventory totes, then orders are processed, but manual handling and processing time increase
Solution Approach 1:
The system enables automated container staging and dispensing without requiring manual sequential picking. Mobile robots autonomously retrieve containers from storage and deliver them to dispensing locations, and the system automatically tracks and manages container inventory, reducing manual intervention while maintaining operational simplicity
Solution Approach 2:
The patent creates a multi-functional system where mobile robots perform both storage retrieval and dispensing delivery functions, and where dispensing locations serve both as storage buffers and customer pickup points. This consolidation reduces the number of separate operations and manual handling steps required
