Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If attribute information is not considered in prediction, then the prediction system is simpler, but the prediction accuracy deteriorates

Engineering Contradiction:
Improveprediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary classification of target devices based on attribute information before prediction. By pre-grouping devices with similar attributes (e.g., device type, specifications, operating conditions) into categories, the system prepares filtered datasets in advance, which improves prediction accuracy without adding complex real-time processing requirements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The prediction system segments the overall device population into distinct groups based on attribute information. Each segment is handled by a dedicated prediction model trained on specific attribute characteristics, allowing the system to maintain high accuracy for each segment while keeping individual model complexities manageable.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If attribute information filtering is applied, then prediction accuracy improves, but data processing time increases

Engineering Contradiction:
Improveprediction accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

Attribute-based filtering and device classification are performed in advance to pre-organize historical data into attribute-specific datasets. This preliminary action eliminates the need for time-consuming filtering operations during real-time prediction, as the system can directly access pre-filtered data corresponding to the target device's attributes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system applies different filtering and processing strategies tailored to each attribute category. Rather than uniformly processing all data, the system selectively applies attribute-specific filters and models only to relevant data subsets, reducing overall processing time while maintaining accuracy for each specific case.

Inventive Principle:
Principle #3Local quality
