3D Structural Model Overlay for Damage Cause Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current structure inspection methods require significant manpower and are inefficient in identifying the causal events of damage, as they rely on two-dimensional diagrams and extensive information gathering, making it difficult to determine the cause of damage and plan repairs effectively.
Innovation Solution
A three-dimensional display device and method that overlays damage on a structural model, displaying events with causal relationships using a processor-driven system, allowing for notification of causal events through markers, color coding, and chronological or positional ranking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two-dimensional damage diagrams and design drawings are used to specify the cause of damage, then the inspection can be performed, but the work requires a large amount of manpower and time, making it inefficient
Solution Approach 1:
The patent transitions from two-dimensional damage diagrams to three-dimensional visualization of the structure model. By displaying damage positions and causal events on a 3D model, inspectors can spatially understand the relationships between damages and their causes without manually analyzing multiple 2D diagrams, significantly improving inspection efficiency and reducing time consumption.
Solution Approach 2:
The patent combines multiple information elements (structure geometry, damage positions, causal events, and their relationships) into a single integrated three-dimensional visualization. This merging of previously separate 2D diagrams and data into one cohesive 3D display allows inspectors to comprehensively analyze damage causes in a unified view, reducing the manpower and time required.
2Loss of information
If multiple two-dimensional damage diagrams are used to analyze positional relationships, then the cause of damage can be specified, but the device complexity and information processing burden increase
Solution Approach 1:
The patent uses three-dimensional visualization to preserve complete spatial information about damage positions and causal relationships without requiring multiple separate 2D diagrams. The 3D model inherently captures positional relationships in all directions, maintaining information completeness while simplifying the processing and display burden.
3Loss of information
If inspectors manually analyze weather, temperature, humidity, and traffic volume data, then causal events can be identified, but the ease of operation decreases and the process becomes cumbersome
Solution Approach 1:
The patent merges environmental data (weather, temperature, humidity, traffic volume) with structural damage data in a unified three-dimensional visualization system. Causal events are displayed alongside damage positions on the 3D model, allowing inspectors to easily correlate environmental conditions with damage occurrences without manually analyzing separate data sets, thereby improving ease of operation while maintaining information completeness.
4Reliability
If inspection managers confirm a large amount of inspection materials, then the inspection results can be verified, but it takes time for search and confirmation, reducing productivity
Solution Approach 1:
The patent enables verification of inspection results through three-dimensional visualization, where managers can spatially understand damage positions and causal relationships in context. This 3D display allows for more intuitive and efficient verification compared to reviewing extensive 2D materials, improving both reliability and productivity in the verification process.

AI summary
Provided are a three-dimensional display device, a three-dimensional display method, and a program capable of notifying a user of an event having a causal relationship with a damage. The three-dimensional display device (10) includes a memory (16) that stores a three-dimensional model of a structure, a damage displayed in the three-dimensional model, and an event that has a causal relationship with the damage; a display unit (26); and a processor (20). In the three-dimensional display device (10), the processor (20) causes the display unit (26) to display the three-dimensional model, superimpose the damage on the three-dimensional model and display the damage, and display the event having the causal relationship with the damage.
