Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual checking of comparing spatial structure with CAD model is performed manually, then diagnostic accuracy can be achieved, but task time is prolonged and skilled operators are required
Solution Approach 1:
The patent creates a digital copy of the spatial structure by capturing images with an image shooting apparatus and generating a model image from CAD data. This digital copy is then superimposed with the captured image to enable automated comparison, replacing manual visual checking while maintaining diagnostic accuracy and reducing task time
Solution Approach 2:
The patent replaces the mechanical/manual visual checking process with an automated image processing system. The control unit automatically superimposes the model image with the captured image and detects misalignments, substituting human operators with automated computational methods to reduce task time while maintaining precision
2Measurement precision
If manual visual checking is performed to diagnose faults, then diagnostic precision can be maintained, but the complexity of the diagnostic process increases
Solution Approach 1:
The patent creates a digital replica of the physical spatial structure through image capture and CAD model integration. This digital copy enables automated superimposition and comparison, maintaining diagnostic precision while simplifying the process by eliminating manual visual inspection steps
Solution Approach 2:
The patent introduces a control unit as an intermediary that automatically performs the superimposition and comparison tasks. This intermediary handles the complex image processing operations, reducing the complexity burden from manual operators while maintaining high diagnostic precision through automated analysis
3Productivity
If superimposition of model image and shot image is performed, then diagnostic efficiency is improved, but image alignment accuracy may be compromised
Solution Approach 1:
The patent creates accurate digital copies through systematic image capture using an image shooting apparatus and precise CAD model representation. This ensures that both the shot image and model image are faithful representations of the actual spatial structure, maintaining alignment accuracy while enabling efficient automated comparison
Solution Approach 2:
The patent employs feedback mechanisms where the control unit detects misalignments between the superimposed images and uses this information to identify faults. The system continuously refines the comparison process by analyzing the degree of misalignment, ensuring accurate results while maintaining high diagnostic efficiency through automated iterative analysis

AI summary
A computer displays a plurality of edge lines extracted from a shot image of a spatial structure that has been shot by an image shooting apparatus, and a plurality of ridge lines included in a model image represented by model information of the spatial structure, in a manner such that the edge lines and the ridge lines are selectable. Then, the computer accepts a selection instruction indicating an edge line and a ridge line of an overlay target. Finally, in accordance with the accepted selection instruction, the computer displays a superimposition image in which the model image has been superimposed onto the shot image in a manner such that the edge line and the ridge line of the overlay target overlap each other.
