Engineering Contradictions & Design Principles
Engineering 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
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.
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.
2Ease of operation
If traditional LoRaWAN networks are deployed with centralized control, then network management is simplified, but security and confidentiality are compromised
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.
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.
3Productivity
If nodes communicate directly without intermediaries, then communication efficiency is improved, but security and payment enforcement become difficult
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.
4Adaptability or versatility
If decentralized network deployment is enabled, then flexibility and adaptability are improved, but device complexity and coordination challenges increase
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.
