Solution Overview

Problem

Field operators in plants face challenges in responding promptly to atypical operations due to lack of immediate support for unexpected facility abnormalities, leading to delayed troubleshooting and potential incorrect decisions, especially for less experienced personnel.

Innovation Solution

A portable operation support system that includes a portable terminal device equipped with a position information detector, inspection information processor, and a user interface, allowing field operators to access inspection routes, routine and atypical operation instructions, and historical data for quick decision-making and troubleshooting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If field operators search for materials manually in offices, then they can find repair and replacement information, but it takes too much time and they cannot respond immediately to facility troubles

Engineering Contradiction:
Improveaccess to repair informationVSAvoidresponse time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

A portable terminal device serves as an intermediary between field operators and the central server, enabling operators to access repair information, operation guides, and facility data remotely while moving through the plant, eliminating the need to return to offices for material searches

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system pre-loads and stores operation guides, repair procedures, and facility information in the portable terminal device before operators need them, so that all necessary information is immediately available at the point of need without time-consuming searches

Inventive Principle:
Principle #10Preliminary action

2Productivity

If field operators rely on their own judgment for troubleshooting decisions, then they can make quick decisions, but less experienced operators may make incorrect decisions

Engineering Contradiction:
Improvedecision speedVSAvoiddecision accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system provides feedback mechanisms where operators can input observed symptoms and the system returns recommended actions based on historical data and expert knowledge, ensuring decisions are grounded in proven effectiveness rather than just operator intuition

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables self-service troubleshooting by providing operators with automated diagnostic support and decision recommendations, allowing even less experienced operators to make reliable decisions without needing extensive personal expertise

Inventive Principle:
Principle #25Self-service

3Ease of operation

If field operators follow fixed inspection routes and lists, then they can perform routine inspections systematically, but they cannot immediately access support for atypical operations outside the inspection list

Engineering Contradiction:
Improveroutine inspection processVSAvoidresponse to atypical operations
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts from static inspection lists to dynamic support provision, where the portable terminal can access and provide information for both routine inspection items and atypical operations based on real-time operator needs and facility conditions

Inventive Principle:
Principle #15Dynamics
