Solution Overview

Problem

Current inventory management systems face challenges in efficiently consolidating items across locations due to manual, non-trackable processes, which lead to subjective decision-making and inefficiencies in space utilization, especially in rapidly changing environments.

Innovation Solution

An electronic apparatus and method for inventory management that receives consolidation task requests, identifies items based on real-time space usage rates, and updates inventory information, allowing for automated allocation of items with high or low order rates to optimize storage and picking processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual consolidation tasks are performed using a stock transfer tool according to a manual, then the consolidation process can be executed, but the process becomes non-trackable and subject to subjective decision-making

Engineering Contradiction:
Improveconsolidation process executionVSAvoidprocess trackability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system implements automated feedback loops where space usage rates are continuously monitored and fed back to the consolidation management server. This enables objective, data-driven consolidation decisions rather than subjective manual judgments, resolving the contradiction between ease of operation and process reliability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical consolidation processes with an automated electronic system that calculates space usage rates and generates consolidation task lists automatically. This substitution eliminates non-trackable manual operations while maintaining ease of execution through automated guidance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If consolidation tasks are performed manually without real-time data, then the process is simple to execute, but space utilization optimization is inefficient

Engineering Contradiction:
Improvespace utilization optimizationVSAvoidsystem automation level
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary calculations of space usage rates and pre-generates consolidation task lists before actual consolidation execution. This preliminary automated analysis optimizes space utilization efficiency while keeping the actual consolidation process straightforward for workers to follow.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The consolidation management server acts as an intermediary between raw space usage data and consolidation execution. It processes real-time volumetric data, applies optimization algorithms, and translates complex calculations into simple task lists, resolving the contradiction between optimization productivity and system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If real-time volumetric space usage rate calculation is implemented, then inventory status is reflected accurately, but the system complexity increases

Engineering Contradiction:
Improveinventory status reflectionVSAvoidreal-time calculation system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements self-service automation where the electronic apparatus automatically captures volumetric data, calculates space usage rates, and updates inventory status without requiring complex manual measurement systems. This maintains high measurement precision while managing system complexity through automated self-measurement capabilities.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If automated consolidation task lists are generated based on space usage rates, then picking tasks are uniformly standardized, but the initial setup and processing complexity increases

Engineering Contradiction:
Improvepicking task uniformityVSAvoidautomated task generation system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system changes the parameter basis for consolidation decisions from subjective manual criteria to objective volumetric space usage rate parameters. This standardization enables uniform picking tasks while the automated calculation of these parameters manages the complexity of the decision-making process.

Inventive Principle:
Principle #35Parameter changes
