Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inventory management systems rely heavily on human operators, leading to errors and inefficiencies, and require customized automated robots for specific tasks, resulting in complexity and high costs, with bottlenecks forming due to limited task capabilities of specialized robots.
Innovation Solution
A system of interchangeable automated mobile robots configured to operate in multiple modes (replenishment, defragmentation, order fulfillment, and delivery) based on real-time demand, allowing them to perform various tasks across the automated store, optimizing inventory management and reducing the need for excess robots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If customized specialized robots are used for specific tasks, then task performance reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal mobile robot platform that can perform multiple tasks including order fulfillment, replenishment, delivery, and storage management through software configuration rather than hardware specialization. The robot includes interchangeable end effectors and adjustable operational modes that enable it to adapt to different task requirements, eliminating the need for separate specialized robots for each function.
2Adaptability or versatility
If multiple specialized robots are deployed for different tasks, then task capability versatility is improved, but quantity of robots and cost increase
Solution Approach 1:
A single mobile robot design serves multiple functions through configurable software modes and interchangeable end effectors. The robot can switch between order fulfillment, replenishment, delivery, and storage management tasks, replacing the need for multiple specialized robot fleets and reducing overall system cost.
Solution Approach 2:
The robot's operational characteristics are dynamically adjusted through software configuration rather than fixed hardware design. The same physical platform can be reconfigured for different tasks by loading appropriate software modules and attaching suitable end effectors, enabling flexible adaptation to changing task requirements without requiring additional specialized robots.
3Manufacturing precision
If specialized robots are used for each task, then task execution precision is improved, but ease of operation and management deteriorate
Solution Approach 1:
The universal robot platform maintains task execution precision through specialized software modules and interchangeable end effectors that are optimized for specific tasks, while simplifying management through a unified control system that manages all robot functions from a single interface.
Solution Approach 2:
The robot's operational parameters are dynamically changed through software configuration rather than physical reconfiguration. The same hardware platform can switch between tasks by loading different software parameters and operational modes, maintaining precision while simplifying management.
4Reliability
If fixed-mode robots are deployed, then operational reliability for specific tasks is improved, but adaptability to changing demand deteriorates
Solution Approach 1:
The robot system transitions from fixed hardware specialization to dynamic software-based task assignment. The same physical robot can be dynamically reassigned to different tasks based on real-time demand through software reconfiguration, maintaining operational reliability through proven task-specific software modules while gaining flexibility to adapt to changing requirements.

AI summary
A system and method for managing a plurality of automated mobile robots within automated mobile robot storage and retrieval system is provided, which repurposes one or more automated mobile robots operating within the automated inventory management system to perform a plurality of tasks across multiple different areas of an automated store. The same mobile robot is enabled to move horizontally and vertically in a multi-level storage structure, operate in an order fulfillment mode retrieving order totes from an automated fulfillment section and delivering the order totes to the delivery section, operate in a replenishment mode receiving eaches of goods and depositing the eaches of goods in designated storage totes, and operate in a delivery mode receiving delivery bundles and transporting the delivery bundles to designated locations at the transfer station.
