Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If measurement devices collect comprehensive energy consumption data and physical parameters at high sampling rates, then measurement precision and data completeness are improved, but the quantity of data increases significantly making analysis difficult

Engineering Contradiction:
Improveenergy consumption measurement precisionVSAvoidquantity of measurement data
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent segments the large volume of measurement data into smaller time-series segments or data chunks, which are then processed and analyzed individually. This segmentation allows the system to handle comprehensive measurement data without being overwhelmed by the total quantity, maintaining measurement precision while making the data manageable for analysis.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts key features and characteristics from the comprehensive measurement data, such as typical consumption patterns, anomalies, and relevant parameters. By extracting only the essential information from the large dataset, the system maintains measurement precision while reducing the quantity of data that needs to be stored and analyzed.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of information

If comprehensive measurement data is collected from multiple sensors and meters, then data completeness is improved, but the complexity of processing and analyzing the data increases

Engineering Contradiction:
Improvedata completenessVSAvoiddata processing system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent merges data from multiple sensors and measurement devices into a unified processing framework. By combining the data streams and applying integrated processing algorithms, the system maintains complete information from all sources while reducing the overall complexity of handling multiple separate data streams through standardized processing procedures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a universal data processing platform that can handle various types of measurement data (energy consumption, physical parameters, operational data) through a single system architecture. This multi-functional approach maintains data completeness from diverse sources while avoiding the complexity of separate processing systems for each data type.

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

3Measurement precision

If detailed analysis of energy consumption patterns is performed, then detection precision of anomalies is improved, but the time required for analysis increases

Engineering Contradiction:
Improveanomaly detection precisionVSAvoidanalysis time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary processing of measurement data, including segmentation, feature extraction, and pre-analysis, before detailed anomaly detection is conducted. By preparing the data in advance and identifying obvious patterns early, the system achieves high anomaly detection precision while reducing the time required for the final detailed analysis phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual or mechanical analysis methods with automated computational algorithms for detecting anomalies in energy consumption patterns. This substitution enables detailed analysis of comprehensive data with high precision while significantly reducing the time required, as automated systems can process data much faster than human analysts.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
