Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud platform is used for device linkage control, then device information can be stored and operations can be forwarded, but real-time response is delayed and security is compromised
Solution Approach 1:
The patent extracts the cloud platform intermediary from the device linkage control process. Devices establish direct peer-to-peer connections through local area network or wireless networks, eliminating the need for cloud-based data transfer and storage. This extraction resolves the contradiction by removing the source of both delay and security vulnerability while maintaining device communication capability.
Solution Approach 2:
The patent introduces a token-based authentication mechanism as a lightweight intermediary for security verification. Instead of relying on cloud-based authentication servers, devices exchange and verify tokens locally. This mediator enables secure direct communication without the delays and security risks associated with cloud platform intermediation.
2Adaptability or versatility
If cloud platform stores all device information, then device linkage can be achieved, but security becomes a bottleneck and information leakage risk increases
Solution Approach 1:
The patent segments device information storage and processing across individual devices rather than centralizing it in the cloud. Each device maintains its own information locally, and only necessary communication data is exchanged peer-to-peer. This segmentation eliminates the single point of failure and information leakage risk associated with centralized cloud storage while preserving full device linkage capability.
Solution Approach 2:
Devices perform their own authentication and information verification independently through token validation, without relying on cloud-based security services. This self-service approach distributes security responsibilities across devices, eliminating the security bottleneck and information leakage risks inherent in centralized cloud storage architectures.
3Ease of operation
If cloud platform forwards all linkage operations, then device communication can be established, but operational complexity and network access requirements increase
Solution Approach 1:
The patent extracts the operation forwarding function from the cloud platform and implements it directly between devices. Devices establish direct communication channels and execute operations locally without cloud intervention. This extraction simplifies the network architecture by removing unnecessary intermediaries while maintaining ease of operation through automatic peer-to-peer connection establishment.
Data Source
AI summary
The present application relates to the technical field of Internet of Things control, and provides a device linkage control method and system. According to the device linkage control method, after detecting information, a main control device determines a controlled device according to a linkage type by querying a linkage parameter table, the controlled device interacts with token information generated by the controlled device, and execution information is sent to the controlled device, so as to achieve a linkage operation on the controlled device. The whole linkage process does not require the participation of a cloud platform, and also does not require a user to input any account and password information, which improves the timeliness of the linkage operation, reduces the delay of the linkage operation, and also reduces the operational difficulty of the linkage operation and improves the user's experience.
