Zigbee Install Code Printing via Radio Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for printing Zigbee install codes on Zigbee devices are prone to errors due to the risk of mixing up the device with the NFC card or label, leading to incorrect code printing and potential network access issues.
Innovation Solution
A method that reads the Zigbee install code from the device via a radio interface, allowing for direct printing on the device or its case, even after full assembly, thus eliminating the risk of code mix-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the install code is read via serial interface before full assembly, then the code can be captured, but physical access to connection terminals is required which increases complexity and risk of mixing up devices with NFC cards or labels
Solution Approach 1:
The patent replaces the mechanical/physical connection method (serial interface requiring physical access to terminals) with a wireless radio interface method. The install code is read wirelessly from the Zigbee device without needing to physically connect to connection terminals, thereby eliminating the need for disassembly and reducing the risk of mixing up devices with NFC cards or labels.
2Ease of manufacture
If the install code is read before full assembly, then the code can be printed on NFC cards or labels, but additional information carriers are required which increase manufacturing time and costs
Solution Approach 1:
The patent extracts and eliminates the intermediate information carrier (NFC card or label) from the production process. By reading the install code wirelessly directly from the Zigbee device and printing it directly on the device itself, the process removes the need for separate NFC cards or labels, thereby reducing manufacturing steps, time, and costs.
3Reliability
If the install code is read via radio interface from assembled device, then direct printing is possible eliminating mix-up risk, but the device must remain accessible via radio interface
Solution Approach 1:
The patent performs the radio interface reading operation at a specific timing point - after mechanical assembly is complete but before the device is packaged or the radio interface becomes inaccessible. This preliminary action ensures the install code is captured while the device is still accessible via radio interface, allowing direct printing on the assembled device without subsequent mix-up risks.
