Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If sensor data is collected and stored in a centralized database, then data accessibility is improved, but data reliability and protection against manipulation deteriorate

Engineering Contradiction:
Improvedata accessibilityVSAvoiddata reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides the centralized database into a distributed network of nodes, where sensor data is segmented and stored across multiple independent locations. This segmentation prevents single-point manipulation while maintaining data accessibility through the distributed network structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces cryptographic checksums and smart contracts as intermediary layers between the sensor data and the distributed database. These intermediaries verify data integrity and prevent manipulation, ensuring reliability while allowing accessible data storage across the distributed network.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If manual sensor calibration is performed, then measurement precision is improved, but operator work and time consumption increase

Engineering Contradiction:
Improvesensor calibration accuracyVSAvoidcalibration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements automatic sensor calibration through smart contracts that continuously monitor sensor data and autonomously adjust calibration parameters when deviations are detected. This self-service mechanism eliminates manual calibration operations while maintaining measurement precision, thereby reducing operator work and time consumption.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent establishes a feedback loop where sensor data is continuously analyzed against predefined thresholds, and calibration adjustments are automatically applied based on this feedback. This closed-loop system ensures measurement precision is maintained without requiring manual intervention, reducing both operator work and calibration time.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If flexible production locations are used, then adaptability is improved, but data verification and quality control become more difficult

Engineering Contradiction:
Improveproduction location flexibilityVSAvoidproduct quality consistency
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent creates a universal distributed database system and smart contract framework that can be deployed across any production location. This universal infrastructure ensures consistent data verification and quality control mechanisms are applied uniformly across all flexible production sites, maintaining manufacturing precision regardless of location.

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

Solution Approach 2:

The patent implements preliminary verification through smart contracts that automatically validate sensor data and manufacturing parameters before production begins at any location. This preliminary action ensures quality standards are established in advance, enabling flexible production location selection without compromising product quality consistency.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If cryptographic verification is implemented for all sensor data, then data reliability is improved, but processing time and computational resources increase

Engineering Contradiction:
Improvedata integrityVSAvoiddata processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies cryptographic verification selectively rather than uniformly to all sensor data. Smart contracts implement partial verification by focusing cryptographic checks on critical parameters and threshold violations, rather than verifying every data point. This partial action approach maintains data reliability for essential measurements while reducing overall processing time and computational resource consumption.

Inventive Principle:
Principle #16Partial or excessive action
