Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple image captures from different viewpoints are performed sequentially to analyze three-dimensional structure, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent combines multiple viewpoint images into a single composite image that contains three-dimensional structural information. By merging the information from multiple angles into one integrated image, the system achieves 3D structure analysis without requiring sequential capture from multiple viewpoints, thus reducing analysis time while maintaining measurement precision.
Solution Approach 2:
The patent introduces a new dimensional approach by creating a composite image that encodes three-dimensional spatial information in a two-dimensional format. This dimensional transformation allows the system to capture and analyze 3D structure data in a single image capture, eliminating the need for sequential multi-viewpoint capturing and significantly reducing analysis time.
2Productivity
If multiple cameras are used to capture images simultaneously from different viewpoints, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple camera views into a single composite image through image processing. This approach maintains the productivity benefit of simultaneous multi-viewpoint capture while reducing device complexity by processing the combined information in software rather than requiring complex hardware coordination and synchronization systems.
