Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If analysis is performed without considering learner attributes, then the analysis process is simple, but the state estimation accuracy deteriorates

Engineering Contradiction:
Improvestate estimation accuracyVSAvoidanalysis complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the analysis process into multiple processing stages: data acquisition from sensors, attribute information retrieval, state estimation processing, and result output. This segmentation allows complex attribute-based analysis to be broken down into manageable steps, improving accuracy while maintaining analytical tractability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediate processing unit that receives both sensor data and attribute information, then integrates them to produce state estimates. This intermediary component acts as a mediator that combines multiple data sources systematically, enabling accurate attribute-based analysis without overwhelming system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple types of measurement information are collected, then the state estimation accuracy improves, but the data processing complexity increases

Engineering Contradiction:
Improvestate estimation accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges multiple measurement data streams (sensor data, attribute information) into a unified analysis framework. By combining these diverse data types through a centralized processing approach, the system achieves comprehensive state estimation while avoiding the complexity of separate processing systems for each data type

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a universal processing framework that handles multiple types of measurement information through a single integrated system. This multi-functional approach allows the same processing infrastructure to accommodate various sensor inputs and attribute data, reducing overall system complexity while maintaining high estimation accuracy

Inventive Principle:
Principle #6Universality (Multi-functionality)
