Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing short-range communication technologies (Wi-Fi, Bluetooth, ZigBee) are used, then device connection is possible, but communication flexibility and adaptability are limited
Solution Approach 1:
The patent implements dynamic role assignment where devices can switch between main control node and terminal node roles based on real-time communication needs. The controller dynamically determines device roles, negotiates communication parameters, and adjusts connection modes, enabling flexible adaptation to different scenarios while maintaining manageable complexity through automated role management
Solution Approach 2:
The patent changes communication parameters dynamically by allowing devices to negotiate and switch between different role configurations (main control node/terminal node). This parameter change approach enables the same hardware to adapt to various communication scenarios without requiring multiple dedicated devices or complex protocol stacks
2Adaptability or versatility
If fixed role assignment is used in device connections, then device roles are clearly defined, but communication flexibility is reduced
Solution Approach 1:
The system implements dynamic role assignment where the controller determines device roles based on actual communication scenarios. Devices can transition between main control node and terminal node roles as needed, providing flexibility while maintaining reliability through the controller's centralized coordination that ensures role transitions are managed orderly and connections remain stable
Solution Approach 2:
The controller uses feedback mechanisms to determine device roles by evaluating communication needs and device capabilities in real-time. This feedback-driven approach allows the system to adapt roles dynamically while maintaining connection stability through continuous monitoring and adjustment, ensuring that role assignments always match current communication requirements
3Productivity
If next-generation short-range access technology is implemented, then communication efficiency is improved, but device connection methods are not specifically specified
Solution Approach 1:
The patent introduces a controller as an intermediary that manages device connections in next-generation short-range access technology. The controller handles role determination, parameter negotiation, and connection establishment, thereby improving communication efficiency through optimized protocols while reducing the complexity burden on individual devices by centralizing connection management functions

AI summary
This application provides a device connection method, an electronic device, and a system. For a next-generation short-range access technology, a controller and a basic service layer are configured in an electronic device. The controller, the basic service layer, and a peer device interact with each other, to establish a control channel in the electronic device, so as to implement a connection between electronic devices, and provide a basis for subsequent data transmission. In addition, in the short-range access technology provided in this application, final roles of two electronic devices may be determined based on expected roles of the two electronic devices, so that the roles of the two electronic devices can be flexibly changed based on an actual scenario, and communication flexibility is high.
