Solution Overview

Problem

In shared warehouse facilities, there is a challenge in managing and preventing the incorrect unloading of transporting tools such as pallets, which are shared among multiple users, leading to potential misallocation and misuse.

Innovation Solution

A warehouse facility is designed with a storage area, work area, and management units that allocate and manage transporting tools using unique codes for each user and tool, ensuring that unloading operations are authorized based on the stored relationships between tool codes and user codes, thereby preventing incorrect unloading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If transporting tools are shared among multiple users to improve resource utilization, then productivity increases, but the risk of incorrect unloading and misallocation increases

Engineering Contradiction:
Improveresource utilizationVSAvoidcorrect unloading
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements feedback mechanisms where the storage area management unit communicates with the comprehensive management unit to verify tool codes against user codes before permitting unloading operations. This closed-loop feedback ensures that only authorized users can unload their allocated transporting tools, preventing misallocation while maintaining shared resource efficiency.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The comprehensive management unit acts as an intermediary between the work block management units and the storage area management unit. It mediates the unloading permission process by receiving unloading requests, verifying the relationship between tool codes and user codes, and coordinating with the storage area management unit to execute authorized unloading operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a comprehensive management system is implemented to manage tool codes and user codes, then reliability of tool allocation improves, but device complexity increases

Engineering Contradiction:
Improvetool allocation accuracyVSAvoidmanagement system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The comprehensive management unit performs multiple functions: it manages tool codes for all transporting tools, manages user codes for all users, stores usage-related information linking tools to users, processes unloading requests, and coordinates with both work block and storage area management units. This multi-functional approach consolidates complexity into a single versatile component rather than distributing it across multiple specialized systems.

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

Solution Approach 2:

The system enables self-service through automated verification processes. When a user requests to unload a transporting tool, the comprehensive management unit automatically verifies the tool code against the stored usage-related information and the user code, and coordinates with the storage area management unit without requiring manual intervention. This automation reduces operational complexity while maintaining high reliability.

Inventive Principle:
Principle #25Self-service

AI summary

A warehouse facility for transporting and storing transporting tools for placing articles thereon or putting articles therein when the articles are transported is disclosed in which the transporting tools handled by a plurality of users can be appropriately managed. If an unloading request is made from a target block management unit Mb, a comprehensive management unit Mt gives a storage area management unit Ms an unloading transport instruction to perform unloading transport for a transporting tool P for which the unloading request has been made, under an unloading permission condition that the relationship between a tool code Cp designated in the unloading request and a user code Ch of a target user H1, H2 is stored in usage-related information Ih.
