Wireless Load Group Control for Lighting State Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems face challenges in synchronizing the state of multiple lighting devices, leading to some devices being out of sync, and lack a universal status indicator for various electrical loads, causing confusion for end users.
Innovation Solution
A remote control device that communicates wirelessly to synchronize the on/off state and intensity of multiple lighting devices, providing visual feedback through a status indicator, and can be configured to work with various load control devices, including lighting, HVAC, and motorized window treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a common lighting control device controls a group of lighting devices, then the lighting devices can be collectively controlled, but some lighting devices may become out of sync with the rest of the group
Solution Approach 1:
The control device receives status information from each lighting device in the group and uses this feedback to determine whether devices are in sync. This allows the system to detect out-of-sync conditions and respond appropriately by sending synchronization commands or notifying the user.
Solution Approach 2:
The control device sends a synchronization command to lighting devices before they may become out of sync, or immediately upon detecting potential desynchronization. This preliminary action prevents the out-of-sync condition from occurring or resolves it before the user notices.
2Adaptability or versatility
If different types of electrical loads are controlled by a single control device, then the device can control diverse loads, but the status indicator may cause confusion to the end user
Solution Approach 1:
The control device provides different status indications for different types of electrical loads based on their specific characteristics. Each load type receives a customized status representation that is appropriate for its nature, allowing the universal control device to maintain clear, non-confusing status indication for each specific load type.

AI summary
A load control system may include control devices for controlling electrical loads. The control devices may include load control devices, such as a lighting device for controlling an amount of power provided to a lighting load, and controller devices, such as a remote control device configured to transmit digital messages for controlling the lighting load via the load control device. The remote control device may communicate with the lighting devices via a hub device. The remote control device may detect a user interface event, such as a button press or a rotation of the remote control device. The remote control device or the hub device may determine whether to transmit digital messages as unicast messages or multicast messages based on the type of user interface event detected. The remote control device, or other master device, may synchronize and/or toggle an on/off state of lighting devices in the load control system.
