Dimmer Status Indicator Idle State Wake-Up Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dimmers lack an effective mechanism to conserve energy by reducing the intensity of status indicators after a period of inactivity, leading to unnecessary power consumption and visibility issues in bright environments.
Innovation Solution
A touch dimmer with a voltage source switchable between low and high intensity for status indicators, which transitions to a dim mode after a predetermined period of inactivity, reducing power usage and maintaining visibility in sunlight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If status indicators are kept at high intensity continuously, then visibility in bright environments is improved, but power consumption increases
Solution Approach 1:
The status indicators dynamically adjust their illumination intensity based on system activity state. During active operation, indicators maintain high intensity for visibility. During idle periods, indicators automatically reduce to low intensity, creating a dynamic adaptation to operational conditions that resolves the contradiction between visibility and power consumption.
Solution Approach 2:
The system implements periodic monitoring of activity states and transitions status indicators between high and low intensity modes. A timer mechanism creates periodic checks for user interaction, switching indicators to low intensity after a threshold period of inactivity, thereby reducing power consumption while maintaining visibility during actual use periods.
2Use of energy by moving object
If status indicators are dimmed to save energy, then power consumption is reduced, but visibility in low light conditions deteriorates
Solution Approach 1:
The status indicators dynamically respond to system state changes. When the system detects active user interaction or transitions from idle state, indicators automatically increase intensity from low to high, ensuring visibility is restored precisely when needed while maintaining energy savings during periods when visibility is not critical.
3Loss of information
If status indicators remain brightly lit continuously, then user feedback visibility is improved, but energy waste increases
Solution Approach 1:
The system employs periodic activity detection to determine when status indicators should maintain high intensity versus when they can be dimmed. By implementing time-based thresholds for activity detection, the system ensures user feedback remains visible during interaction periods while automatically reducing intensity during extended idle periods, thereby minimizing energy waste without sacrificing critical feedback visibility.

AI summary
A load control device comprises an actuator for controlling a connected lighting load and a plurality of status indicators for displaying the intensity of the lighting load as feedback to a user. One or more of the status indicators are illuminated to a bright active level when the actuator is actuated. After a predetermined amount of time, the intensity of the status indicators is faded one of two dim levels depending upon whether the lighting load is on or off. Accordingly, the load control device will "wake up", i.e., the status indicators will illuminate to the bright active level, upon another actuation of the actuator.
