Infrared Control Device Tag Scanning for Mesh Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infrared control devices in mesh network environments require connection to a cloud database to download control instructions, leading to usability issues when a connection is unavailable.
Innovation Solution
Infrared control devices that record and store control instructions directly on an identification tag, eliminating the need for a cloud database connection by using a tag identification module and database to scan and store control instructions for controlled devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control instructions are downloaded from a cloud database via network connection, then the control device can obtain control instructions for controlled devices, but the system requires external network connection which reduces reliability when network is unavailable
Solution Approach 1:
The infrared control device is designed to perform multiple functions: it can obtain control instructions through network connection when available, and alternatively scan identification tags directly when network is unavailable. This multi-functionality ensures the device maintains control capability across different network conditions, resolving the contradiction between reliability and system complexity.
Solution Approach 2:
The identification tag serves as an intermediary carrier that stores control instructions locally. Instead of requiring direct network connection between the control device and cloud database, the identification tag mediates the transmission of control instructions, enabling operation without external network connection and thus improving reliability.
2Ease of operation
If control instructions are downloaded from cloud database, then control instructions can be obtained, but the process requires network connection which reduces ease of operation when connection is unavailable
Solution Approach 1:
Control instructions are pre-stored on identification tags before use. When the control device needs to control a controlled device, it simply scans the identification tag to obtain the pre-stored control instructions. This preliminary action eliminates the need for real-time network connection during operation, improving both ease of operation and reliability.
3Adaptability or versatility
If the control device connects to cloud database to download control instructions, then the control instructions can be obtained, but the system becomes dependent on external network connection
Solution Approach 1:
The system is segmented into independent components: the control device, the identification tag, and optionally the cloud database. The identification tag contains self-contained control instructions that can be read by the control device without requiring connection to the cloud database. This segmentation allows the system to adapt to different network environments while maintaining independent operation capability.

AI summary
An infrared control device (1, la) is configured for use in a mesh network environment to control a controlled device (90) by transmitting an infrared signal. The controlled device (90) includes an identification tag (91). The identification tag (91) includes a first control instruction (911). The control device (1,1a) includes a tag identification module (20, 81) and a database (30). The tag identification module (20, 81) scans the identification tag (91) to identify the first control instruction (911). The database (30) is electrically connected to the tag identification module (20, 81) to store the first control instruction (911).
