Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is collected and recorded without verification, then data quantity and service provision speed are improved, but data reliability and service quality deteriorate due to potential anomalous data

Engineering Contradiction:

Improvedata collection efficiencyVSAvoiddata quality

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary sensing and verification of data anomalies before recording data in the distributed ledger. The sensing server detects anomalous data patterns in advance, and authentication servers verify transaction data before consensus, preventing unreliable data from being stored while maintaining efficient data collection processes

Inventive Principle:

Principle #10Preliminary action

2Reliability

If data verification and consensus algorithms are implemented, then data reliability is improved, but system complexity and processing time increase

Engineering Contradiction:

Improvedata validityVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides verification responsibilities into specialized components: sensing servers detect anomalies, authentication servers verify transactions, and consensus algorithms validate data. This segmentation allows each component to focus on specific verification tasks, improving reliability while managing complexity through modular architecture

Inventive Principle:

Principle #1Segmentation

3Loss of information

If all collected data is recorded in the distributed ledger, then data availability is improved, but storage efficiency deteriorates due to inclusion of anomalous data

Engineering Contradiction:

Improvedata accessibilityVSAvoidstorage resources

Core Design Contradiction:

Loss of informationVSLoss of substance

Solution Approach 1:

The system extracts and identifies anomalous data through sensing and verification processes before recording. By taking out problematic data through anomaly detection and verification failures, the system ensures only valid data is stored in the distributed ledger, optimizing storage efficiency while maintaining data availability

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A control method for an anomalous data sensing system including at least a plurality of authentication servers and including: sensing whether data obtained from a device is not anomalous; obtaining first transaction data including information indicating the data; verifying, by a first authentication server included in the plurality of authentication servers, the first transaction data obtained, when the data is sensed as not being anomalous; and recording a block including the first transaction data into a distributed ledger when an agreement about validity of the first transaction data is reached using a consensus algorithm.
