Lighting Show Time Override for Task-Specific Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load control systems fail to meet user-specific needs for light output adjustments, as they do not allow for easy customization of light parameters beyond predefined schedules.
Innovation Solution
A load control system that includes control devices capable of adjusting light output parameters based on a user-defined show time, allowing users to easily adjust settings such as light intensity, color temperature, and window covering positions through input devices like keypads or network devices, enabling task-specific lighting configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated light control systems use predefined schedules to adjust light output over time, then the system provides automatic control and simplifies user operation, but the system lacks flexibility to meet user-specific task needs
Solution Approach 1:
The system dynamically switches between automated schedule-based control and manual override modes. Users can temporarily pause or adjust the automated schedule to meet specific task needs, and the system adapts by allowing real-time parameter modifications while maintaining the underlying automated framework.
Solution Approach 2:
The system allows users to modify light output parameters (intensity, color temperature, timing) by overriding the predefined schedule. Users can adjust these parameters to meet specific task requirements while the system maintains the ability to return to or reset the original automated schedule.
2Adaptability or versatility
If the system allows manual adjustments to light parameters, then user flexibility and task-specific customization improve, but system complexity increases
Solution Approach 1:
The system uses an intermediary override mechanism that sits between the automated schedule and the actual light output control. This intermediary layer allows users to temporarily pause or adjust the schedule without fundamentally changing the system architecture, maintaining simplicity while enabling customization.
Solution Approach 2:
The control system is designed to handle both automated schedule execution and manual overrides through a unified control interface. The same control devices and communication protocols are used for both automated and manual operations, reducing the need for separate complex subsystems.
3Adaptability or versatility
If the system tracks show time based on current time of day, then the system provides natural light simulation, but the system cannot easily adapt to user-specific timing needs
Solution Approach 1:
The show time tracking is made dynamic by allowing users to pause or adjust the time progression. Users can temporarily halt the show time to maintain natural light simulation conditions during extended tasks, or speed up/slow down the progression to match their specific timing needs, while the system maintains the ability to resume normal tracking.

AI summary
Systems and methods are disclosed for a load control system which produces a show by adjusting one or more parameter values, such as color temperature, intensity, spectrum, volume, load state, and position of a window covering, as a function of a show time equal to a current time of day. The load control system is responsive to receiving commands to adjust the show time with respect to the current time of day. The load control system is configured to respond to the received commands by initiating a temporary system override in which the one or more parameter values may rewind or forward in time according to the defined show. The temporary override may exit and the defined show may resume at the current time of day after a predetermined amount of time has passed, at a reset time, or in response to a command.
