Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user account registration is used for inter-device linking, then device control function is provided, but convenience deteriorates when multiple users exist and security risks increase due to shared pairing information

Engineering Contradiction:

ImprovesecurityVSAvoidconvenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts and removes the user account information dependency from the device pairing process. Instead of requiring user accounts for inter-device linking, the system enables direct device-to-device pairing through local communication protocols, eliminating the security vulnerability of shared pairing information while maintaining operational convenience

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary pairing mechanism that facilitates direct communication between devices without requiring user account mediation. The pairing process uses local discovery and authentication protocols that enable devices to establish secure connections independently of user accounts, resolving both the security and convenience issues

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If user account registration is required for device linking, then device control service is provided, but device complexity increases due to account management requirements

Engineering Contradiction:

Improvedevice control serviceVSAvoidaccount management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables devices to perform self-service pairing without external account management systems. Devices automatically discover each other through local communication, authenticate using device-specific credentials, and establish connections independently, eliminating the need for user account registration and reducing system complexity while maintaining full device control functionality

Inventive Principle:

Principle #25Self-service
