Solution Overview

Problem

Existing storage warehouse systems face complexity and increased costs when handling articles of differing sizes, as they require separate configurations for each size, leading to inefficiencies and higher operational expenses.

Innovation Solution

A storage warehouse design that includes an attachment mechanism allowing articles of different sizes to be handled using the same system, with a transport apparatus and buffer part enabling the transformation of larger articles into a form that matches the size of smaller articles, allowing them to be stored and retrieved using common shelves and transport mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If separate transport systems are prepared for each article size, then positioning accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single transport system that can handle multiple article sizes through interchangeable attachments. The attachment unit can be exchanged to match different storage container sizes, allowing the same transport apparatus to accurately position both small and large articles without requiring separate systems for each size category.

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

Solution Approach 2:

The patent implements dynamics by making the transport system configurable through attachment exchange. Rather than a fixed configuration, the system dynamically adapts to different article sizes by replacing the attachment unit, enabling the same base structure to maintain positioning accuracy across varying dimensions.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If separate storage configurations are prepared for each article size, then storage precision is improved, but device complexity increases

Engineering Contradiction:
Improvestorage precisionVSAvoidconfiguration complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by creating storage shelves and attachment units that work together in a standardized system. The attachments are designed to interface with universal shelf structures, allowing precise storage of different sized articles on the same shelf system without requiring separate storage configurations for each article size.

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

3Measurement precision

If multiple transport systems are installed for different article sizes, then handling accuracy is improved, but cost increases

Engineering Contradiction:
Improvehandling accuracyVSAvoidsystem cost
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single transport system with interchangeable attachments that can handle multiple article sizes. This eliminates the need to purchase and maintain separate transport systems for different sizes, reducing overall system cost while preserving handling accuracy through proper attachment matching.

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

Solution Approach 2:

The patent merges the functionality of multiple size-specific transport systems into a single unified system. By combining the base transport apparatus with exchangeable attachments, the system achieves the handling accuracy of specialized systems while avoiding the cost of maintaining multiple separate systems.

Inventive Principle:
Principle #5Merging (Combining)

4Measurement precision

If separate systems are used for each article size, then positioning accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvepositioning accuracyVSAvoidoperational simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent applies universality by creating a standardized attachment interface that works with the same transport system regardless of article size. Operators work with a consistent system and procedures, exchanging attachments rather than switching between different systems, which simplifies operation while maintaining positioning accuracy.

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