Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual setup and configuration of wireless mesh networks is performed, then network security and stability can be maintained, but setup time and operational complexity increase significantly

Engineering Contradiction:

Improvenetwork stabilityVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring mesh nodes with unique identifiers and codes before deployment. The system automatically scans these pre-prepared codes and registers nodes with a registration computer, eliminating the need for manual on-site configuration while maintaining security through automated verification of node credentials before network integration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service through automated node registration and configuration. Mesh nodes autonomously present their unique identifiers, the user device scans and validates their codes, and the system automatically completes registration without requiring manual intervention for configuration, thereby reducing setup time while maintaining reliability through automated security checks.

Inventive Principle:

Principle #25Self-service

2Productivity

If automated node registration is implemented, then setup efficiency improves, but security risks increase due to potential vulnerabilities in automated authentication

Engineering Contradiction:

Improvesetup efficiencyVSAvoidsecurity risks

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent uses an intermediary approach by introducing a registration computer as a secure intermediary between the user device and mesh nodes. This centralized registration authority validates node credentials and manages authentication, separating the automated registration process from direct peer-to-peer trust establishment, thereby maintaining security while enabling automated setup.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies feedback mechanisms through verification of node codes and credentials against stored registration information. The system provides feedback by validating each node's unique identifier and code, ensuring authenticity before allowing network integration. This feedback loop maintains security by continuously verifying node legitimacy while enabling automated registration.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If multiple mesh nodes are added simultaneously, then network scalability improves, but configuration errors and instability increase

Engineering Contradiction:

Improvenetwork scalabilityVSAvoidconfiguration stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies segmentation by processing multiple node registrations through a structured, modular approach. Each node is scanned, validated, and registered independently through discrete steps, allowing multiple nodes to be added simultaneously while maintaining configuration stability through systematic processing and individual verification of each node's credentials.

Inventive Principle:

Principle #1Segmentation

4Use of energy by moving object

If low-power wireless communication is used for node scanning, then energy consumption decreases, but communication range and data transmission capability are limited

Engineering Contradiction:

Improveenergy consumptionVSAvoidcommunication range

Core Design Contradiction:

Use of energy by moving objectVSLength of stationary object

Solution Approach 1:

The patent extracts the critical identification and registration function from the main wireless mesh network communication. By using low-power communication only for the initial node scanning and code reading phase, and reserving high-power or wired communication for subsequent data transmission and network integration, the system achieves low energy consumption during setup without compromising overall communication capability.

Inventive Principle:

Principle #2Taking out (Extraction)
