Solution Overview

Problem

Existing systems for managing plant inspections lack the ability to dynamically control the display of information based on the roles of operators and site workers, leading to inefficiencies in the inspection process.

Innovation Solution

A plant management device equipped with display control means that displays a plant model on a display device, receiving user operations, and displaying information corresponding to the user's role and operation, allowing for tailored information presentation for operators and site workers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple pieces of management information are displayed on a single display device, then information completeness is improved, but readability and understandability deteriorate due to screen clutter

Engineering Contradiction:
Improveinformation completenessVSAvoidreadability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The display device is divided into multiple virtual display regions (first display region, second display region, third display region) that can independently present different management information. This segmentation allows comprehensive information display while maintaining readability within each region, as each region can be optimized for its specific content type.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes spatial arrangement of multiple display regions on the screen, creating a two-dimensional layout that organizes information hierarchically. Different information types are placed in different spatial zones, allowing the system to present multiple pieces of information simultaneously without cluttering a single viewing area.

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

2Quantity of substance

If management information is displayed in a list format, then information completeness is improved, but understanding the degree of influence on productivity deteriorates

Engineering Contradiction:
Improveinformation completenessVSAvoidproductivity influence understanding
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

Different display regions are assigned different functions: the first display region shows management information with productivity influence indicators, while the second display region displays detailed lists. This local quality differentiation allows each region to serve its specific purpose optimally, with the first region providing productivity context and the second providing comprehensive information.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The first display region acts as an intermediary between the detailed list information and the productivity assessment. It translates detailed management information into productivity influence indicators that are easier to understand, serving as a bridge that preserves information completeness while enhancing productivity understanding.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If detailed management information is displayed, then information completeness is improved, but screen clutter increases reducing readability

Engineering Contradiction:
Improveinformation completenessVSAvoidscreen clutter
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The screen is segmented into multiple functional regions that organize detailed management information in a structured manner. This segmentation reduces perceived clutter by creating visual boundaries and hierarchies, allowing detailed information to be displayed without overwhelming the user interface.

Inventive Principle:
Principle #1Segmentation
