VSEngineering Contradiction Analysis

1Measurement precision

If a rich database of reference images is used to compute atmospheric precipitation rates, then measurement precision is improved, but storage resources are significantly increased

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The invention extracts and removes the dependency on reference image databases from the precipitation rate computation system. Instead of comparing captured images against stored reference images, the system uses a mathematical model that directly computes precipitation rates from image features, thereby eliminating the need for extensive storage resources while maintaining computation accuracy

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the physical storage of reference images with a mathematical model that can be represented and stored in a compact form. The model captures the essential relationships needed for precipitation rate computation without requiring actual image copies, significantly reducing storage requirements

Inventive Principle:
