Ceiling Fan Speed Control Discovery for Multi-Device Commissioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load control systems face challenges in efficiently identifying and activating remotely located fan-speed control devices, such as ceiling fans, due to their hidden installation and high inertia, making it difficult for users to distinguish between multiple devices during commissioning.
Innovation Solution
A network device initiates a discovery mode by cycling power to the circuit, prompting fan-speed control devices to enter a discovery mode, transmit discovery requests, and receive user confirmation of obstruction-free ceiling fans, allowing easy identification and activation through visible indicators or commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fan-speed control devices are installed remotely in ceiling locations, then the system can control ceiling fans effectively, but the devices become difficult to identify and distinguish during commissioning
Solution Approach 1:
The patent employs visual indicators that change or activate to help users identify specific fan-speed control devices. The indicator mechanism provides visual feedback (such as LED lights or display changes) to distinguish between multiple remotely installed devices, enabling users to accurately identify and select the correct device during commissioning without physical access.
2Adaptability or versatility
If multiple fan-speed control devices are installed in the same space, then the system can control multiple fans, but users experience confusion during commissioning about which device corresponds to which fan
Solution Approach 1:
The system provides feedback mechanisms through visual indicators that respond to device activation and selection. When a fan-speed control device is activated or selected, the indicator provides immediate visual confirmation to the user, helping them understand which device is active and reducing confusion when multiple devices are present in the same space.
Solution Approach 2:
Visual indicators use color changes or illumination patterns to represent different device states and identities. This allows users to distinguish between multiple fan-speed control devices and understand their current operational status without requiring physical proximity or manual testing of each device.
3Stability of the object's composition
If ceiling fans have high inertia, then they maintain stable operation, but they are difficult to start and stop quickly during commissioning testing
Solution Approach 1:
The system performs preliminary identification and selection of the correct fan-speed control device before attempting to control the fan. By using visual indicators to help users accurately identify and select the intended device, the system prevents erroneous control attempts that would be ineffective due to fan inertia, ensuring that control commands are directed to the correct device from the outset.

AI summary
Systems, methods, and apparatus are described herein for configuring (e.g., activating) a fan-speed control device in a wireless control system. The fan-speed control device may control a rotational speed of a ceiling fan. The fan-speed control device may enter a discovery mode and turn off the ceiling fan in response to entering the discovery mode. The network device may receive a selection of a discovered fan-speed control device. The fan-speed control device may transmit a discovery request message for being discovered by a network device. The network device may transmit a message including an identify command to the discovered fan-speed control device. The fan-speed control device may turn on the ceiling fan to an identification speed in response to receiving the identify command. The user may identify the fan-speed control device corresponding to the ceiling fan being identified in the space to be activated in the wireless control system.
