Retrofit Wall Switch Remote Control for No-Rewiring Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in installing advanced load control systems due to the need for electrical rewiring and hiring skilled installers, and existing wall-mounted light switches can disrupt power to controllable light sources when turned off, preventing remote control functionality.
Innovation Solution
A remote control device that mounts over existing mechanical switches, controlling electrical loads wirelessly without rewiring, and maintains actuators in an on position to prevent accidental power cutoff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advanced load control devices are installed by replacing mechanical switches, then energy savings and control features are improved, but installation complexity and cost increase
Solution Approach 1:
The remote control device is mounted over the existing mechanical switch, with the base attaching to the switch's actuator. This nested configuration allows the new control device to utilize the space and mounting structure of the existing switch, enabling advanced control features without requiring replacement of the mechanical switch or complex re-wiring.
2Adaptability or versatility
If mechanical switches are replaced by load control devices, then control capability is improved, but installation cost and difficulty increase
Solution Approach 1:
The remote control device is designed to be installed by consumers themselves without requiring electrical contractors. The base attaches directly to the mechanical switch's actuator using simple mounting mechanisms, and the device integrates with existing wiring through the switch's internal connections, making installation straightforward and eliminating the need for professional electrical work.
3Loss of energy
If wall-mounted light switches are turned off to control controllable light sources, then power consumption is reduced, but remote control functionality is lost
Solution Approach 1:
The remote control device acts as an intermediary between the mechanical switch and the controllable light source. It receives commands from remote control units and translates them into appropriate signals for the light source, while also monitoring the state of the mechanical switch. This allows the system to maintain remote control functionality even when the mechanical switch is in the off position, by using the mechanical switch only as a master power cutoff rather than a control interface.

AI summary
Remote control devices may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be mounted over a mechanical switch that is installed in a wallbox. The remote control device may include a base, a battery, a battery holder, and a control unit. The base may be configured to attach the remote control device to the mechanical switch. The control unit may be configured to be removably attached to the base. The battery holder may be configured to retain the battery therein. The battery holder may be configured to be installed within the void defined by the housing. The battery holder may be operable between a first position in a lower portion of the void and a second position in an upper portion of the void.
