Remote Load Control With Group Sync and Adaptive Status Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems face challenges in synchronizing lighting devices and providing clear status indicators for various electrical loads, leading to confusion for users and inefficiencies in controlling electrical loads within a user environment.
Innovation Solution
A remote control device that transmits messages to load control devices and provides visual feedback through a status indicator, which adjusts based on the type and status of associated load control devices, including lighting, HVAC, and motorized window treatments, to ensure synchronization and clear user feedback.
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 remote control device receives status information from each lighting device in the group and uses this feedback to determine the current state of the group. This allows the device to identify which lighting devices are out of sync and send targeted control commands to restore synchronization, resolving the contradiction between collective control capability and synchronization reliability.
2Device complexity
If a single status indicator is used for various types of electrical loads, then the device complexity is reduced, but user confusion increases due to different load types having different status meanings
Solution Approach 1:
The status indicator displays different visual characteristics (such as different colors, patterns, or intensities) depending on the type of electrical load being controlled. This allows a single physical indicator to convey load-type-specific information, maintaining device simplicity while preserving status clarity for different load types.
Solution Approach 2:
The status indicator dynamically changes its display characteristics based on the current electrical load type and status. The indicator adapts its behavior to match the controlled load, providing context-appropriate visual feedback without requiring multiple fixed indicators.
3Adaptability or versatility
If independent control of individual lighting devices is allowed, then user flexibility increases, but synchronization issues arise between independently controlled devices and the group
Solution Approach 1:
The system continuously monitors the status of individually controlled lighting devices and compares it with the group status. When synchronization issues are detected, the system can send coordination commands to restore group synchronization, allowing independent control flexibility while maintaining group reliability.

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.
