Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If LoRaWAN networks are deployed to cover large areas, then communication coverage is improved, but deployment resources and infrastructure requirements increase significantly

Engineering Contradiction:
Improvecoverage areaVSAvoiddeployment resources
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent segments the network into independent nodes that can autonomously join and leave the network. Each node operates independently with its own cryptographic keys, allowing the network to scale across large areas without requiring centralized control or extensive infrastructure deployment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Nodes in the patent perform self-service by autonomously generating cryptographic key pairs, selecting their own parents, and managing their own connections. This eliminates the need for manual configuration and reduces deployment resources while enabling large-scale coverage.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If traditional LoRaWAN networks are deployed with centralized control, then network management is simplified, but security and confidentiality are compromised

Engineering Contradiction:
Improvenetwork managementVSAvoidsecurity and confidentiality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements local quality by giving each node its own cryptographic identity and allowing local decision-making for network joins and connections. This distributed approach maintains security while enabling autonomous operation without centralized control.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces cryptographic protocols as intermediaries that enable secure peer-to-peer communication without requiring trusted centralized authorities. The blockchain ledger acts as an impartial mediator for recording transactions and maintaining network state.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If nodes communicate directly without intermediaries, then communication efficiency is improved, but security and payment enforcement become difficult

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidsecurity and payment enforcement
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms through the blockchain ledger that record and verify all communications and transactions. This enables automated payment enforcement and security verification while maintaining efficient peer-to-peer communication, as nodes can quickly verify credentials and payment status on-chain.

Inventive Principle:
Principle #23Feedback

4Adaptability or versatility

If decentralized network deployment is enabled, then flexibility and adaptability are improved, but device complexity and coordination challenges increase

Engineering Contradiction:
Improvedeployment flexibilityVSAvoidcoordination complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamics by allowing the network topology to change continuously as nodes autonomously join, leave, and reconfigure connections. The blockchain ledger dynamically records these changes, enabling flexible deployment while maintaining coordination through cryptographic verification of each node's actions.

Inventive Principle:
Principle #15Dynamics
