Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If individual comparison of captured images with 3D model is performed, then verification accuracy is improved, but verification time increases

Engineering Contradiction:
Improveverification accuracyVSAvoidverification time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines multiple captured images and the 3D model into a single integrated display screen, allowing simultaneous visualization of all comparison elements. This merging approach maintains verification accuracy by preserving individual image-model comparison capability while reducing verification time through consolidated viewing, eliminating the need to switch between multiple displays or files.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent superimposes two-dimensional captured images with a three-dimensional model in a unified display space, creating a multi-dimensional comparison interface. This dimensional integration allows users to verify accuracy across different viewing angles and depths simultaneously, maintaining thorough verification while reducing the time required compared to sequential two-dimensional comparisons.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If detailed difference extraction is performed, then verification precision is improved, but processing complexity increases

Engineering Contradiction:
Improvedifference detection precisionVSAvoidprocessing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs color-coded visualization to represent different types and magnitudes of differences between captured images and the 3D model. By assigning distinct colors to various difference categories (e.g., geometric deviations, texture variations), the system achieves high detection precision while simplifying the user interface and reducing processing complexity through intuitive visual encoding.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent transforms complex difference extraction results into simplified visual parameters displayed on the screen, such as color intensity, overlay transparency, and highlight intensity. This parameter transformation maintains precise difference detection capability while reducing processing complexity by presenting results in an easily interpretable visual format rather than raw data.

Inventive Principle:
Principle #35Parameter changes
