Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hub node from a different IoT system attempts to control a target device, then interconnection across IoT systems is achieved, but the cost and complexity increase significantly
Solution Approach 1:
The patent introduces an access management device as an intermediary between the hub node and the target device. This mediator handles the complex authentication and authorization processes, allowing the hub node to control the target device without directly implementing complex control logic. The access management device translates and manages the control permissions, reducing the complexity burden on the hub node while enabling cross-system interconnection.
2Productivity
If device control authority is set across different IoT systems, then device control capability is improved, but the cost increases
Solution Approach 1:
The patent implements a self-service mechanism where the access management device automatically manages control authority settings. When a hub node needs to control a target device, the access management device automatically performs authentication, generates access tokens, and configures control permissions without requiring manual intervention or expensive external services. This automated self-service approach reduces operational costs while maintaining improved device control capability across different IoT systems.
3Adaptability or versatility
If hub node establishes connection with target device across different IoT systems, then intercommunication is enabled, but system complexity increases
Solution Approach 1:
The patent segments the connection management functionality into distinct components: the hub node handles connection initiation, the access management device handles authentication and authorization, and the target device handles control execution. This segmentation allows each component to focus on specific tasks, reducing the overall system complexity while enabling intercommunication across different IoT systems. The access management device acts as a dedicated segment for handling cross-system connection protocols.
Solution Approach 2:
The access management device serves as an intermediary that simplifies cross-system connection management. It handles the complex protocols and authentication mechanisms required for connecting different IoT systems, shielding the hub node and target device from this complexity. The intermediary translates between different system protocols, enabling seamless intercommunication without requiring either endpoint to implement complex connection management logic.

AI summary
Disclosed in the present application are a device control permission setting method and apparatus, and a device and a storage medium. The method comprises: receiving and responding to a device capability request sent by a hub node that has established a connection relationship with a target controlled device; returning device capability information of the target controlled device to the hub node, so as to instruct the hub node to generate device control information; receiving the device control information sent by the hub node; and setting permission information of the hub node for the target controlled device on the basis of the device control information sent by the hub node, so as to efficiently control the device.
