VSEngineering Contradiction Analysis

1Measurement precision

If coating texture information is provided using large datasets from multiple angles, then measurement precision is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

Solution Approach 1:

The patent extracts only the most relevant texture characteristics from comprehensive multi-angle measurements. The system identifies and extracts key texture parameters that human observers actually perceive, discarding redundant data while maintaining measurement precision for the essential characteristics.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms complex multi-angle texture data into simplified relative texture characteristics through mathematical processing. By changing the parameter representation from raw multi-angle measurements to processed relative characteristics, the system maintains precision while reducing complexity for user interpretation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 1:

The patent introduces relative texture characteristics as an intermediary between raw measurement data and user interpretation. This intermediary layer processes complex multi-angle data into intuitive relative comparisons that users can easily understand while preserving the precision of the original measurements.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the parameter representation from complex multi-angle measurements to simplified relative texture characteristics. This transformation maintains the precision information while presenting it in a format that is much easier for users to interpret and use for matching decisions.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If relative texture characteristics are calculated for all coatings, then texture matching accuracy is improved, but loss of time increases

Engineering Contradiction:
Improvetexture matching accuracyVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent calculates relative texture characteristics for all coatings in advance and stores them in a database. This preliminary action allows the system to quickly retrieve pre-computed characteristics during matching operations, achieving high accuracy without time-consuming real-time calculations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system computes texture characteristics for all available coatings rather than just potential matches. This excessive action ensures that when a target coating is presented, the system can immediately compare against all coatings using pre-computed data, achieving both high accuracy and fast response.

Inventive Principle:
Principle #16Partial or excessive action
