Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If IoT devices use diverse operating systems and configurations to target narrow application spaces, then device versatility and application specificity are improved, but security reliability deteriorates due to lacking security standards

Engineering Contradiction:

Improvedevice versatilityVSAvoidsecurity reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a gateway server as an intermediary between diverse IoT devices and the network. The gateway implements standardized security protocols (IP address restriction, transitory identifiers, encryption) to mediate communications, allowing devices with diverse operating systems to maintain their versatility while achieving uniform security standards through the gateway layer.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If gateway server implements enhanced administrative features with IP address restriction and encryption, then security reliability is improved, but device complexity increases

Engineering Contradiction:

Improvesecurity reliabilityVSAvoidgateway complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The gateway server is designed as a universal security platform that handles multiple security functions (IP address restriction, transitory identifier generation, encryption/decryption, access monitoring) in a single device. This consolidates complexity into one multi-functional component rather than requiring each IoT device to implement individual security features, thereby improving security reliability while managing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Difficulty of detecting and measuring

If gateway server monitors all IoT device communications for security, then security detection capability is improved, but loss of time increases due to processing overhead

Engineering Contradiction:

Improvesecurity detection capabilityVSAvoidcommunication processing time

Core Design Contradiction:

Difficulty of detecting and measuringVSLoss of time

Solution Approach 1:

The gateway server performs preliminary security actions by establishing IP address restrictions and generating transitory identifiers before communications occur. These pre-configured security measures automatically validate communications without requiring real-time analysis of each data packet, thereby maintaining high security detection capability while minimizing processing time overhead during actual device communications.

Inventive Principle:

Principle #10Preliminary action
