Solution Overview

Problem

Existing big data processing technologies struggle to understand specific relationships within groups or regions due to limitations in data collection, storage, and analysis, making it difficult to identify individual device interactions within a network.

Innovation Solution

An electronic apparatus and method that calculates similarity between devices connected to a network by acquiring operation time information, compressing it into bitmap-based time slots, and identifying device groups with high similarity for cluster management and graph-based representation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If statistical techniques are used to analyze big data, then group trends can be identified, but specific individual relationships within the group cannot be understood

Engineering Contradiction:
Improvegroup trend identificationVSAvoidindividual device relationships
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments the analysis into two levels: first, statistical techniques identify group trends from aggregated log data; second, graph-based clustering segments individual devices into specific groups based on similarity metrics, preserving individual relationships while maintaining group-level insights

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from one-dimensional statistical aggregation to multi-dimensional analysis by incorporating device identifiers, operation time information, and similarity calculations, enabling both group trend identification and individual device relationship tracking simultaneously

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If detailed log data of all devices is collected and stored, then individual device relationships can be understood, but data storage and processing complexity increases

Engineering Contradiction:
Improveindividual device relationshipsVSAvoiddata storage and processing
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts only the necessary operation time information from device log data, storing it in a compressed time index format rather than retaining complete detailed logs, thus preserving individual device relationships while reducing storage complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms detailed log data into a simplified parameter representation (operation time information with timestamps) and further compresses it into bitmap-based time slots, maintaining the essential information for relationship analysis while significantly reducing data volume and processing complexity

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If operation time information is compressed into bitmap-based time slots, then data storage efficiency improves, but calculation complexity increases

Engineering Contradiction:
Improvedata storage efficiencyVSAvoidsimilarity calculation process
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent merges multiple operation time records into a single bitmap-based time slot representation, where each bit represents a time unit, efficiently encoding when devices were active. This compression reduces storage requirements while enabling efficient similarity calculations through bitwise operations

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces traditional mechanical comparison methods for analyzing operation times with computational bitmap operations, where similarity between devices is calculated using efficient bitwise AND, OR, and XOR operations on the compressed time slot representations

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