Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smart home and smart medical fields, smart terminals face challenges in accurately connecting with communication modules due to the need to search and select from multiple surrounding networks, leading to potential misconnections.
Innovation Solution
A two-dimensional code based communication method where a smart terminal scans a displayed two-dimensional code to establish communication with a controller, which acquires and updates address information, manages connection thresholds, and verifies user information to ensure accurate and secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart terminal searches all surrounding networks to establish communication, then the terminal can find available communication modules, but the terminal is easily connected to a wrong communication module
Solution Approach 1:
The system performs preliminary actions by generating and displaying a two-dimensional code containing the address information of the communication module before the actual connection process. This allows the smart terminal to obtain the correct address in advance through scanning, eliminating the need to search through multiple surrounding networks and ensuring accurate connection from the start.
2Reliability
If a two-dimensional code is displayed for communication establishment, then the smart terminal can accurately connect to the correct communication module, but the code may become invalid when address information is updated
Solution Approach 1:
The system implements a feedback mechanism where the controller continuously monitors whether the address information of the communication module has changed. When an update is detected, the controller automatically triggers the displaying module to generate and display a new two-dimensional code, ensuring the code always reflects the current address information and maintaining both accuracy and adaptability.
3Adaptability or versatility
If multiple smart terminals connect to the same communication module, then user collaboration is enabled, but connection security and resource management become complex
Solution Approach 1:
The controller serves as an intermediary that manages multiple smart terminal connections to the same communication module. It tracks the number of connected terminals and enforces connection thresholds, automatically preventing new connections when the limit is reached. This intermediary management simplifies the complexity by providing centralized control over multi-terminal access.

AI summary
Disclosed are a two-dimensional code based communication method, a two-dimensional code based communication apparatus, and a two-dimensional code based lift desk, wherein the communication method comprises: acquiring, by a controller, address information of a communication module, and transmitting the address information, together with product information, to a displaying module; generating, by the displaying module, a two-dimensional code based on the address information and the product information, and displaying, by the displaying module, the two-dimensional code; and scanning, by a smart terminal, the displayed two-dimensional code to establish communication with the communication module. The present disclosure may achieve the following effects: upon connecting with the communication module via the smart terminal, it becomes unnecessary to search all surrounding communication modules and then select one to connect; instead, the present disclosure ensures an accurate connection by directly scanning the two-dimensional code, which prevents misconnection and facilitates the user to use; besides, the two-dimensional code is displayed via the displaying module, which avoids aging or loss of the two-dimensional code.
