Solution Overview

Problem

Current inventory management systems in warehouses lack efficiency in optimizing storage and retrieval processes, as they do not effectively utilize user-defined facts and rules to dynamically assign storage spaces based on consumption patterns and current warehouse conditions, leading to suboptimal space utilization and increased operational costs.

Innovation Solution

A method and system that receive item location requests and determine recommended storage or retrieval spaces within a warehouse by using user-defined facts and rules, taking into account the current state of the warehouse, to dynamically assign storage spaces based on anticipated consumption patterns during workflow operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional inventory management systems are used, then storage and retrieval operations can be performed, but space utilization is suboptimal and handling time increases

Engineering Contradiction:
Improvestorage and retrieval efficiencyVSAvoidhandling time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system dynamically determines storage and retrieval locations based on current warehouse state, item characteristics, and consumption patterns rather than using fixed location assignments. This allows the system to adapt to changing conditions and optimize each operation in real-time, reducing handling time and improving space utilization

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates user-defined facts and rules about item consumption patterns and warehouse conditions to continuously optimize location recommendations. By using feedback from actual warehouse operations and consumption data, the system learns and improves its location determination algorithm over time, enhancing productivity while reducing handling time

Inventive Principle:
Principle #23Feedback

2Area of stationary object

If fixed storage location assignments are used, then item retrieval is straightforward, but storage space utilization becomes inefficient

Engineering Contradiction:
Improvestorage space utilizationVSAvoidlocation assignment system complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

Instead of fixed location assignments, the system uses dynamic location determination based on current warehouse state, item properties, and consumption patterns. This allows flexible utilization of available storage spaces while maintaining straightforward retrieval through automated location recommendations presented to users

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system automatically determines optimal storage and retrieval locations by evaluating user-defined facts and rules about item characteristics and consumption patterns. This self-service capability eliminates the need for complex manual location assignment while improving space utilization, as the system autonomously optimizes each location decision

Inventive Principle:
Principle #25Self-service

AI summary

Inventory is managed to minimize the footprint of storage spaces affected by variable production volumes and high inventory turnover. A warehouse includes a plurality of storage spaces for storage of items in the inventory. In response to receiving a request to store or retrieve a particular item, a recommended storage space in the warehouse can be determined for the particular item. The determination can be at least partially based on one or more user-defined facts, one or more user-defined rules, and a current state of the warehouse at the time the item location request is received. The user-defined facts can relate to an item, the inventory, the plurality of storage spaces, and/or the warehouse. The user-defined rules can be configured to dynamically assign storage spaces to the warehouse based at least partially on user-defined indications of how items will be consumed during a workflow performed within the warehouse.
