3D Member Display for Construction Damage Inspection

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing three-dimensional display methods for construction inspection fail to facilitate easy viewing of specific members and their damage information, as unwanted information is displayed and hidden parts are difficult to see.

Innovation Solution

A three-dimensional display device and method that allows users to instruct the display to show or hide specific members and their associated damage information, using a processor to map damage information onto a three-dimensional model and accept user instructions for displaying or hiding members, enabling clear visualization of inspection targets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all members of the construction are displayed on the three-dimensional model, then complete information is provided, but unwanted information is displayed and specific members become difficult to view due to occlusion

Engineering Contradiction:

Improvedamage information completenessVSAvoidmember visibility

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The three-dimensional model is segmented into multiple independent members (beams, columns, slabs, etc.), allowing selective display and hiding of individual members based on inspection needs, thus resolving the conflict between showing complete information and maintaining visibility

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The display state of members is made dynamic and adjustable through user interaction, allowing inspectors to show or hide specific members as needed, transforming the static complete-display approach into a flexible adaptive display system

Inventive Principle:

Principle #15Dynamics

2Loss of information

If damage information is mapped onto all members, then comprehensive inspection data is available, but the information becomes difficult to locate and check

Engineering Contradiction:

Improvedamage information completenessVSAvoidinspection time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

Damage information is segmented and associated with specific members rather than displayed uniformly across all members, allowing inspectors to focus on relevant damage data by selectively displaying only the members containing damage or of interest

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system extracts and highlights damage information from the complete set of member data, allowing selective presentation of only the damage-relevant information while maintaining the option to view complete data when needed

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A CPU 20 that functions as a processor of a three-dimensional display device 10 maps pieces of damage information stored in a storage unit 16 and associated with members of a construction onto members, on a three-dimensional model stored in the storage unit 16, corresponding to the pieces of damage information. When accepting an instruction for displaying an inspection target member of the construction from an operation unit 18, the CPU 20 creates a three-dimensional model of only the member for which the instruction for displaying is accepted and onto which a piece of damage information is mapped and causes a display unit 30 to display the three-dimensional model.
