Solution Overview

Problem

Conventional inventory management systems for large, diverse, and dynamically changing storehouses are slow, labor-intensive, and resource-consuming due to decentralized processing and frequent location changes of storage goods.

Innovation Solution

An automated inventory management system utilizing storage region and goods identification devices to create a data record associating storage goods with their locations, enabling efficient tracking and reordering, with features like image recognition, RFID tags, and Augmented Reality for intuitive management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If decentralized manual inventory management is used, then flexibility in handling diverse goods is maintained, but productivity is low and time consumption is high

Engineering Contradiction:
Improveinventory management efficiencyVSAvoidtime for stock control and reordering
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical inventory management with an automated optical recognition system. The determination device automatically detects storage goods and their positions using optical recognition technology, eliminating the need for manual stock control and significantly improving productivity while reducing time consumption.

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

Solution Approach 2:

The system enables self-service inventory management where the determination device autonomously monitors storage regions, identifies goods positions, and triggers reordering automatically. This eliminates the need for continuous human intervention in stock control operations.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If detailed tracking of storage goods positions is implemented, then inventory accuracy is improved, but device complexity increases

Engineering Contradiction:
Improveposition determination accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The determination device performs multiple functions including optical recognition of storage goods, position determination, data record creation, and reordering triggering. By consolidating these functions into a single multi-functional device, the system achieves high measurement precision without proportionally increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a data record as an intermediary that stores the relationship between storage goods and their positions. This data structure simplifies the complexity by providing a standardized way to represent and manage position information without requiring complex real-time tracking mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If automated determination of storage good positions is implemented, then labor requirements are reduced, but initial resource investment increases

Engineering Contradiction:
Improveautomation levelVSAvoidresource consumption
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The system continuously monitors storage regions and automatically triggers reordering when stock levels are low. This feedback mechanism ensures that the automated system maintains optimal inventory levels without excessive resource consumption, balancing automation benefits with resource efficiency.

Inventive Principle:
Principle #23Feedback
