Solution Overview

Problem

The accuracy and quality of inspection reports for construction machines depend on the competence and experience of the service person, leading to inconsistent quality and increased creation time.

Innovation Solution

An inspection support system equipped with a camera, monitor, and guidance display section that provides guidance images for photographing specific components, ensuring consistent data collection and transmission to a management server for report creation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If inspection data is collected manually by service persons, then the inspection report can be created, but the quality and accuracy of the report depend on the competence and experience of the service person, leading to inconsistent quality

Engineering Contradiction:
Improveinspection report qualityVSAvoidconsistency of inspection quality
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The inspection system performs self-service through automated image capture and processing. The portable terminal automatically captures images of construction machine components, stores them in the image storage unit, and transmits them to the management server, eliminating dependence on service person competence for data collection quality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical process of service persons collecting and recording inspection data is replaced by an automated electronic system. The camera captures images automatically, the portable terminal manages data storage and transmission electronically, and the management server processes images centrally, substituting human manual operations with automated technological systems

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual inspection data collection is used, then inspection reports can be created, but it requires significant creation man-hours

Engineering Contradiction:
Improveinspection report creation efficiencyVSAvoidcreation man-hours
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically capturing and storing inspection images at the time of service visit. The portable terminal captures images of construction machine components and stores them locally, preparing the data in advance for efficient processing and report generation, eliminating the need for time-consuming manual data collection later

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates copies of the inspection data in multiple locations. Images are stored in the portable terminal's image storage unit and simultaneously transmitted to the management server's storage, creating redundant copies that can be processed in parallel, reducing the time required for report creation

Inventive Principle:
Principle #26Copying
