Toggle Switch Control for Lighting and Fan Accessories
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices require additional wiring and installation by an electrician to independently control lighting and additional components, such as fans, using separate switches.
Innovation Solution
A lighting device with integrated control units that receive activation signals from a toggle switch to cycle through operating modes for both light engines and additional components like fans, allowing independent control without additional wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate switches are used to independently control lighting and additional components, then independent control capability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single toggle switch to control multiple operating modes that independently manage lighting and additional components. The control unit interprets different toggle switch activation patterns (single activation, double activation, triple activation) to selectively operate different components, allowing one switch to perform the function of multiple switches while reducing installation complexity
2Adaptability or versatility
If additional wiring is installed to enable independent control of multiple components, then control functionality is improved, but loss of substance and installation cost increase
Solution Approach 1:
The patent eliminates the need for additional wiring by making the existing toggle switch universal. The control unit processes different activation patterns from the same toggle switch to independently control lighting, fans, and other components. This approach maintains full control functionality while avoiding the need to run new wires or install additional switches, thereby reducing material loss and installation costs
3Ease of operation
If a single toggle switch controls multiple operating modes, then ease of operation is improved, but control precision may deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the control precision into distinct segments for different components. The control unit uses activation pattern recognition to segment control precision: single activation precisely controls lighting, double activation precisely controls additional components, and triple activation precisely controls both together. This segmented approach maintains high control precision for each component while keeping the operation interface simple and unified

AI summary
A lighting device having an accessory is provided. The lighting device includes a light engine having two or more operating modes; an accessory comprising at least one additional operable component having at least two operating modes; and a control unit configured to vary the operating modes of the lighting device in accordance with an activation signal received by the control unit. Receipt of the activation signal cycles the lighting device through each of the operating modes.
