Solution Overview

Problem

Existing article storage facilities struggle to manage articles stored in airtight containers within inactive gas environments, as they lack the ability to display the gas supply state and operation states effectively, leading to potential issues with gas concentration and proper article management.

Innovation Solution

An article storage facility with a storage rack, transport portion, gas supplying portions, and a display system that shows the operation state, including the gas supply state for each container, allowing users to monitor and manage the inactive gas environment intuitively, reducing incidents of undesirable gas concentrations and facilitating proper article management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If only article objects are displayed on the CRT display, then the operation interface is simple and intuitive, but the user cannot monitor the gas supply state and container environment conditions

Engineering Contradiction:
Improveoperation interface simplicityVSAvoidgas supply state information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The display interface is segmented into multiple types of information objects: article objects showing article presence, container objects showing container presence, and gas supply state objects showing gas supply status. Each type of object is displayed in its own designated area or with its own visual characteristics, allowing the user to access comprehensive information without cluttering the interface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display transitions from a two-dimensional planar display to a three-dimensional virtual space representation. The storage rack is displayed as a 3D structure with storage sections arranged in space, and various information objects are positioned within this 3D space, allowing users to intuitively understand the spatial relationships and status of articles, containers, and gas supply states.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If detailed operation state information is displayed for each storage section, then proper article management is enabled, but the display complexity and information overload increase

Engineering Contradiction:
Improvearticle management accuracyVSAvoiddisplay system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Different types of information are displayed with different visual characteristics and in different locations based on their importance and nature. Article objects are displayed with one set of visual properties, container objects with another, and gas supply state objects with yet another. This allows users to quickly identify and focus on the most critical information for each storage section without being overwhelmed by uniform detailed data.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The physical storage rack and its components are represented by virtual copy objects in the display system. Each storage section, container, and article has a corresponding virtual object that mirrors its physical state. This virtual copying allows comprehensive monitoring of all operation states without requiring physical access to each component, simplifying the management interface while maintaining complete information.

Inventive Principle:
Principle #26Copying

AI summary

Proper article storage management is made possible in the article storage facility which stores articles in containers and in an inactive gas environment. The article storage facility includes a storage rack having storage sections, a transport portion which transports containers to the storage sections, gas supplying portions each of which supplies inactive gas to the container stored in the storage section, and a display. The display displays display sections such that the arrangement of the display sections corresponds to the arrangement of the storage sections in the storage rack and displays a supply state of inactive gas in each of the display sections.
