Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for establishing device connections in IoT environments are inconvenient, requiring manual selection and input/output operations, which are not feasible for devices without display screens or with limited input capabilities.
Innovation Solution
A method and apparatus using a first device with a camera to capture and recognize a second device's image, acquire its type, and initiate a connection request using a unique identifier from an IoT server, allowing for automatic connection establishment without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual device selection and connection establishment is used, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables devices to automatically discover and connect to each other through image recognition and identifier matching, eliminating the need for manual selection and connection establishment. The first device captures an image of the second device, automatically extracts its identifier, and initiates connection without user intervention, making the system serve itself.
Solution Approach 2:
The patent replaces manual mechanical operations (typing passwords, selecting from lists, confirming connections) with automated optical recognition and electronic identification. The camera-based image recognition system substitutes for manual device pairing procedures, transforming a mechanically intensive process into an automated visual recognition task.
2Ease of operation
If automated connection establishment is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system introduces an intermediary image recognition and identifier extraction mechanism between the user and the connection establishment process. Instead of directly manipulating connection parameters, the user simply points the camera at the target device, and the intermediary system handles image processing, identifier extraction, and connection initiation, masking the underlying complexity.
Solution Approach 2:
The patent uses image copying and analysis to identify the target device. The camera captures a visual copy (image) of the second device, extracts its unique identifier from the image, and uses this copied information to establish connection. This eliminates the need for direct interaction with complex connection interfaces while maintaining connection reliability.
3Productivity
If image recognition and automatic identifier extraction is used, then productivity is improved, but measurement precision requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-registering device identifiers and making them accessible through image recognition. Before connection is needed, devices are already identified and their identifiers are stored in the system, so when connection is required, the process is expedited by retrieving pre-prepared identification information rather than creating it in real-time.

AI summary
A method and apparatus for establishing a device connection applied to a first device with a camera are provided. The method includes acquiring an image of a second device by the first device through the camera, recognizing the type of the second device through the acquired image of the second device, acquiring a device list corresponding to the type of the second device through an IoT server, and identifying the second device in the device list, acquiring a unique identifier of the second device in the current IoT environment, and using the unique identifier of the second device to initiate a connection request to the second device to establish a connection with the second device. The method may automatically establish a connection between devices with less operation of the devices.
