Remote Lighting Control Timing for Lamp Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lighting control systems experience latency and synchronization issues due to RF communication protocols, leading to poor user experience and undesirable visual effects in lighting control.
Innovation Solution
A remote control device with a processor that detects continued user interaction and reduces command message transmission frequency by starting a usage timer, decreasing transmission intervals, and adjusting based on angular velocity and position changes, and illuminating a visual indicator to indicate reduced transmission state.

Engineering Contradiction Analysis
1Speed
If the remote control device transmits command messages at a high transmission frequency in response to continued user interaction, then the lighting level can be adjusted quickly and responsiveness is improved, but the lighting devices may become out of sync and produce undesirable visual effects
Solution Approach 1:
The system dynamically adjusts the transmission frequency based on the duration of user interaction. A usage timer tracks how long the user has been interacting with the control device, and the transmission frequency is modified accordingly - higher frequency for brief interactions, reduced frequency for prolonged interactions. This dynamic adaptation resolves the contradiction by allowing fast response when needed while preventing desynchronization during extended use.
Solution Approach 2:
The system implements feedback through the usage timer mechanism that monitors the duration of user interaction and provides feedback by adjusting transmission frequency. The visual indicator also provides feedback to the user about the current transmission state. This feedback loop enables the system to automatically balance between responsiveness and synchronization stability based on actual usage patterns.
2Ease of operation
If the remote control device transmits command messages frequently to maintain responsiveness, then user interaction responsiveness is improved, but latency in the lighting control system increases due to RF protocol limitations
Solution Approach 1:
The system uses periodic command message transmission based on the usage timer. Instead of continuous transmission, commands are sent at periodic intervals determined by the duration of user interaction. This periodic action reduces overall transmission frequency and associated latency while maintaining responsiveness during the interaction window, resolving the contradiction between ease of operation and time loss.
3Duration of action of moving object
If the remote control device continues to transmit command messages during prolonged user interaction, then continuous lighting adjustment is maintained, but the lighting devices may not be controlled in a uniform manner
Solution Approach 1:
The transmission frequency is dynamically reduced when the usage timer indicates prolonged interaction. This dynamic adjustment ensures that while lighting adjustment continues over an extended duration, the transmission rate is modulated to maintain uniform control across all lighting devices, preventing the desynchronization that would occur with constant high-frequency transmission.
Solution Approach 2:
The system changes the transmission frequency parameter based on the usage timer state. For prolonged interactions, the transmission frequency parameter is modified to a lower value, which maintains the duration of lighting adjustment while ensuring uniform control across devices. This parameter change resolves the contradiction between duration and control uniformity.

AI summary
A remote control device for controlling lighting devices may be configured to detect an excessive user interaction (e.g., a continued user interaction) and reduce a number of command messages that are being transmitted to prevent the lighting devices from producing undesirable visual effects. The remote control device may comprise a user interface (e.g., that may include a rotation portion, such as a rotary knob) and a processor configured to receive an indication of a user interaction via the user interface. The processor may periodically transmit command messages at a transmission frequency in response to a continued user interaction, where each of the command messages comprise a respective command for adjusting to a respective lighting level. The processor may also start a usage timer in response to receiving the indication of the user interaction, and decrease the transmission frequency in response to the usage timer exceeding a usage threshold.
