Multi-Tote Item Association for Unified Picking Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In materials handling facilities, managing and tracking inventory items across multiple totes and users is inefficient, as existing systems lack a unified method to associate and consolidate items across multiple totes and users, leading to potential errors and inefficiencies in inventory management.
Innovation Solution
A system that associates multiple totes with a single user profile, using item identifier readers and image capture devices to detect and track items as they are added or removed from totes, updating a profile item identifier list and tote item identifier lists in real-time, allowing for seamless item tracking and management across connected totes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple totes are managed separately without association, then each tote can be independently tracked, but inventory management becomes inefficient and error-prone due to lack of consolidation
Solution Approach 1:
The patent associates multiple totes with a single user profile by merging their item identifier lists into a consolidated view. The system combines item tracking across first and second totes under one profile, allowing unified inventory management without requiring separate tracking systems for each tote, thereby improving efficiency while maintaining manageable system complexity.
2Reliability
If items are tracked across multiple totes using separate lists, then each tote can be individually monitored, but a unified view of all items is lost leading to potential errors
Solution Approach 1:
The system merges item identifier lists from multiple totes associated with a user profile into a unified consolidated list. This consolidation provides a complete view of all items across all totes, eliminating information loss and reducing tracking errors while maintaining the ability to individually monitor each tote through the profile association.
Solution Approach 2:
The system provides feedback by updating the consolidated item identifier list in real-time as items are added or removed from any associated tote. This feedback mechanism ensures the unified view remains accurate and current, improving reliability by continuously synchronizing the consolidated list with the actual state of all totes.
3Productivity
If manual tracking methods are used for items across multiple totes, then system complexity is minimized, but time consumption and operational efficiency decrease
Solution Approach 1:
The system implements self-service tracking by automatically detecting when items are placed into or removed from totes using item identifier readers. The associated totes and user profile automatically update their item identifier lists without manual intervention, eliminating time-consuming manual tracking while maintaining simple operational procedures.
Solution Approach 2:
The patent replaces manual mechanical tracking methods with automated detection systems using item identifier readers and electronic list management. This substitution eliminates the time required for manual recording and updating of item lists across multiple totes, significantly improving operational efficiency without adding complex manual procedures.

AI summary
This disclosure describes a system for associating multiple totes with a single profile so that items placed into any of the multiple totes are identified on a profile item identifier list. For example, if two users located in a materials handling facility are picking items that are to be consolidated or otherwise treated together, each user may select a different tote and move separately through the materials handling facility. As either user picks items and places those items into a corresponding tote, a profile item identifier list is updated to include an item identifier for each picked item.
