Device Pairing via Server-Mediated Image Identifier Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device connection methods, which rely on generating and printing unique two-dimensional codes for each communications device, result in reduced production efficiency and increased costs due to potential failures in code generation and the need for one-to-one correspondence, leading to high fault possibilities.
Innovation Solution
A method where a terminal device acquires an image identifier, sends it to a server to retrieve characteristic information, detects connection information from communications devices, and selects a target device by comparing this information to establish a connection, eliminating the need for unique codes on each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If unique two-dimensional codes are generated and printed on each communications device, then device identification accuracy is improved, but production efficiency deteriorates due to batch generation failures and one-to-one correspondence requirements
Solution Approach 1:
The patent applies universality by using a common image identifier for all communications devices of the same model rather than unique identifiers for each device. This allows the same two-dimensional code to be universally used across multiple devices, eliminating the need for individual code generation and printing for each device while maintaining accurate device identification through characteristic information matching.
Solution Approach 2:
The patent uses copying by allowing the same image identifier (two-dimensional code) to be copied and applied to multiple communications devices of the same model. Instead of creating unique codes for each device, the system copies the same identifier across devices and distinguishes them through characteristic information such as device numbers, thereby improving production efficiency while maintaining identification accuracy.
2Reliability
If unique two-dimensional codes are generated for each communications device, then device tracing capability is improved, but production costs increase due to batch generation and one-to-one correspondence processes

3Adaptability or versatility
If any terminal device can add any communications device remotely, then device addition flexibility is improved, but system security deteriorates due to unauthorized remote additions
Solution Approach 1:
The patent applies feedback by implementing a verification mechanism where the terminal device sends characteristic information to the server, and the server responds with matching results. The system uses two-way feedback: the terminal provides device characteristics, receives matching communications devices from the server, and the server verifies the terminal's credentials before allowing device addition. This ensures secure authorized addition while maintaining flexibility.
Solution Approach 2:
The patent uses an intermediary (the server) to mediate between the terminal device and communications devices. The server acts as a trusted third party that verifies device characteristics, performs matching operations, and authorizes connections. This intermediary mechanism ensures that only authorized devices can be added while maintaining system security, preventing direct unauthorized pairings.

AI summary
The present disclosure discloses a communications device connection method, a terminal device, and a server system. The method includes: acquiring an image identifier of a communications device, sending the image identifier to a server side, and receiving characteristic information of at least one dimension for a device type of the communications device, where the characteristic information is returned by the server side based on the image identifier; detecting connection information sent by at least one communications device, obtaining a device identifier of the at least one communications device by parsing the connection information, and obtaining to-be-matched characteristic information of at least one dimension for a type of the registered at least one communications device from the server side based on the device identifier; comparing the characteristic information of the at least one dimension for the device type of the communications device with the to-be-matched characteristic information of the at least one dimension for the type of the registered at least one communications device, and selecting a target communications device; and binding to and establishing a communications connection to the target communications device.
