Solution Overview

Problem

Existing methods for executing inspections in air conditioning systems are inefficient, particularly in determining the optimal schedule for inspections across multiple apparatuses with varying abnormality response times and influences on each other.

Innovation Solution

An inspection execution method that determines a schedule for air conditioning systems, prioritizing inspections based on abnormality response times and influences, using a management server and mobile terminal to coordinate and execute inspections efficiently, including scheduling, execution, and result management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If inspections are executed without a determined schedule, then all inspections can be performed, but the inspection time and efficiency are reduced

Engineering Contradiction:
Improveinspection efficiencyVSAvoidinspection time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by determining an inspection schedule in advance that includes the order of executing multiple inspections. This scheduled approach allows inspections to be executed efficiently without unnecessary delays, resolving the contradiction between inspection efficiency and inspection time by planning ahead rather than ad-hoc execution

Inventive Principle:
Principle #10Preliminary action

2Reliability

If inspections with long abnormality response time are executed after inspections with short abnormality response time, then all inspections can be completed, but the response time for critical abnormalities increases

Engineering Contradiction:
Improveabnormality response timeVSAvoidinspection completion efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system changes the execution parameter by prioritizing inspections based on their abnormality response time characteristics. Inspections with longer abnormality response times are scheduled to be executed first, while those with shorter response times follow. This parameter-based scheduling ensures critical inspections are completed promptly while maintaining overall inspection productivity

Inventive Principle:
Principle #35Parameter changes

3Loss of time

If inspections with large influence on other inspections are executed concurrently, then inspection time is reduced, but inspection accuracy and reliability deteriorate

Engineering Contradiction:
Improvetotal inspection timeVSAvoidinspection result accuracy
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system segments inspections into different categories based on their influence relationships. Inspections with large influence on other inspections are separated and executed sequentially, while inspections with small influence are grouped and can be executed concurrently. This segmentation allows the system to reduce total inspection time through parallel execution of independent inspections while maintaining reliability by avoiding concurrent execution of highly interdependent inspections

Inventive Principle:
Principle #1Segmentation

AI summary

An inspection execution method is performed by a computer to cause each of a plurality of apparatuses to execute a plurality of inspections. The inspection execution method includes determining an inspection schedule including at least order of the plurality of inspections, and causing the apparatuses to execute the inspections based on the determined inspection schedule.
