Paddle Switch Clamp Base for Wire-Free Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in installing advanced load control devices without professional help due to the need for electrical wiring, 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 with a base and control unit that attaches to a mechanical switch's paddle actuator, allowing installation without electrical wiring, featuring a clamp arm and screw mechanism for secure attachment and a wireless communication circuit for controlling load devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanical switch is replaced by a load control device, then advanced control functionality is achieved, but installation complexity increases due to electrical wiring requirements
Solution Approach 1:
The patent uses an existing mechanical switch as an intermediary component to enable load control functionality without requiring replacement of the switch or access to electrical wiring. The control device attaches to the external actuator of the mechanical switch, allowing consumers to install advanced control features while the mechanical switch continues to serve as the power control mechanism.
2Ease of operation
If a wall-mounted light switch is operated to an off position, then power control is achieved, but controllable light source cannot respond to remote control commands
Solution Approach 1:
The patent applies preliminary action by keeping the mechanical switch in the on position continuously, and instead uses the control device to pre-establish wireless communication and control pathways before any lighting control is needed. This allows the system to maintain power flow while enabling remote control functionality through preliminary setup of the control mechanism.
3Adaptability or versatility
If a mechanical switch is disconnected and removed for installation of a load control device, then advanced control is achieved, but installation cost increases due to professional contractor requirements
Solution Approach 1:
The patent enables self-service installation by designing a control device that attaches to the external actuator of an existing mechanical switch, eliminating the need for consumers to perform electrical wiring or disconnect the mechanical switch. The device can be installed by average consumers without professional electrical contractors, making the system accessible and cost-effective.

AI summary
A remote control device may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be configured to be mounted over an installed mechanical switch having a paddle actuator and may include a base and a control unit that is configured to be removably attached to the base. The base may include a frame, a clamp arm, a screw, and/or a sleeve. The clamp arm may be configured to secure the base to a protruding portion of the paddle actuator. The clamp arm may be attached to the frame at a pivot joint. The clamp arm may be configured to pivot about the pivot joint. The pivot joint may be located proximate to an endpoint or a midpoint of the frame.
