Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If image information is registered without considering rotation angle, then registration process is simple, but data organization and retrieval efficiency deteriorate

Engineering Contradiction:

Improvedata retrieval efficiencyVSAvoidregistration system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system segments image information based on rotation angle attributes, creating distinct registration destinations for different rotation angles (e.g., 0°, 90°, 180°, 270°). This segmentation enables efficient retrieval by filtering images according to their rotation angle, directly resolving the contradiction between simple registration and efficient data organization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary classification of images by rotation angle before registration, pre-determining the appropriate registration destination based on the detected rotation angle. This preliminary action streamlines the subsequent registration process and improves retrieval efficiency without adding complex real-time processing during registration.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If rotation angle detection is performed, then image registration accuracy is improved, but processing time increases

Engineering Contradiction:

Improverotation angle measurement accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system replaces complex manual measurement methods with automated optical detection mechanisms. The image information acquisition unit automatically detects rotation angles through optical reading and processing, eliminating time-consuming manual measurement while maintaining high precision in rotation angle determination.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the parameter of image registration from simple binary registration to multi-parameter registration that includes rotation angle information. By incorporating rotation angle as a key parameter, the system achieves accurate registration without requiring additional complex processing steps, as the rotation angle is directly extracted and used for registration destination determination.
