Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coordination of multiple autonomous Internet of Things (IoT) devices in a spatial area is challenging due to the complexity of central coordination, requiring high computing power and communication bandwidth, and there is a need for decentralized, secure, and transparent movement coordination to prevent collisions and ensure smooth operations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If central coordination is used to coordinate movements of autonomous IOT devices, then coordination effectiveness is improved, but system complexity and computing power requirements increase significantly
Solution Approach 1:
The patent divides the centralized coordination system into multiple distributed nodes that each independently participate in consensus formation. Instead of one central coordinator, the system segments coordination functions across all devices, reducing single-point complexity while maintaining collective coordination effectiveness through blockchain-based consensus mechanisms.
Solution Approach 2:
The patent introduces a blockchain-based distributed ledger as an intermediary layer that enables coordination without direct central control. This intermediary provides transparent, immutable record-keeping and consensus validation, allowing devices to coordinate reliably while the intermediary handles the complexity of trust and agreement verification.
2Reliability
If central coordination is implemented to manage multiple autonomous IOT devices, then movement coordination is improved, but communication bandwidth requirements increase
Solution Approach 1:
The patent segments communication traffic into essential consensus-related data and optional detailed movement data. Only critical coordination information is transmitted through the bandwidth-constrained channel, while less critical data can be handled locally or through alternative channels, reducing overall bandwidth requirements while preserving coordination reliability.
Solution Approach 2:
The patent extracts and separates the essential coordination function from detailed movement control. The blockchain network handles only the critical consensus and coordination decisions, while individual devices independently execute their own movement control based on the coordinated framework, reducing the communication burden on the central system.
3Device complexity
If decentralized consensus network is used for coordination, then system complexity is reduced, but coordination speed may be affected
Solution Approach 1:
The patent implements preliminary action by pre-configuring consensus parameters, validation rules, and communication protocols before coordination events occur. This preparation allows the decentralized network to operate more efficiently during actual coordination, reducing the time needed for consensus formation while maintaining the simplified system architecture.
Solution Approach 2:
The patent employs periodic action through time-bounded consensus rounds and structured communication intervals. By organizing decentralized consensus into periodic cycles with defined phases for proposal, validation, and commitment, the system maintains reduced complexity while achieving predictable coordination speeds through rhythmic, organized interaction patterns.
