NFC Configuration Transfer for Load Control Network Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load control devices in energy control networks face cumbersome and time-consuming processes for initial configuration, specific device database updates, and network integration, particularly due to the need for physical connections or complex button sequences, which limits user functionality and requires device replacement when faulty.
Innovation Solution
The implementation of Near Field Communication (NFC) for low-data-rate, close-proximity wireless protocols to facilitate the download of initial and specific device databases, network configurations, and user interfaces, enabling easy setup and transfer of configurations between devices, including those that become inoperative.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical electronic connection or complex button sequences are used for device configuration and database updates, then device functionality can be established, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces physical electronic connections (mechanical contact-based configuration) with wireless NFC communication. The NFC interface allows devices to exchange configuration data and databases wirelessly through electromagnetic fields, eliminating the need for physical connectors and complex button sequences, thereby significantly reducing configuration time and improving ease of operation.
2Adaptability or versatility
If devices are integrated into wireless communication networks, then network functionality is achieved, but the integration process becomes cumbersome and time-consuming
Solution Approach 1:
The patent applies wireless NFC communication to replace traditional mechanical or manual network integration methods. Devices can be quickly paired and integrated into the wireless communication network through NFC tapping, which automatically establishes connections and transfers necessary network configuration data, dramatically reducing integration time while maintaining full network adaptability.
3Loss of information
If device databases are updated through physical connections, then specific device configurations can be downloaded, but the process requires cumbersome physical connections
Solution Approach 1:
The patent uses wireless NFC communication to transfer device databases and configuration information, replacing physical connection-based methods. The NFC interface enables bidirectional data exchange between devices, allowing complete device databases to be downloaded and updated wirelessly through simple NFC tapping, improving both ease of operation and data transfer reliability.
4Reliability
If faulty devices are replaced, then system reliability is maintained, but device replacement requires complex configuration processes
Solution Approach 1:
The patent implements automatic configuration copying through NFC communication. When a device is replaced, the new device can automatically copy its configuration and database from the replacement source device via NFC tapping, eliminating the need for manual reconfiguration. This copying mechanism maintains system reliability while dramatically simplifying the repair and replacement process.

AI summary
An energy control network may include a number of load control devices, such as dimmer switches, multi-button selector switch, occupancy sensors, and remote controllers, among others. These load control devices may be configured for wireless communication. Other wireless devices, such as laptops, tablets, and “smart” cellular phones may be configured to communicate with the load control devices of the energy control network. The load control devices and the other wireless communication devices may also be configured for Near Field Communication (NFC). NFC may be used to provide a load control device with its initial default configuration and/or an application specific configuration. Also, NFC may be used to transfer a configuration from one load control device that may have become faulty, to a replacement load control device. And NFC may be used to provide and trigger commands that may cause a load control load device to operate in a predetermined manner.
