Switch Paddle Clamp Base for Wire-Free Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of advanced load control systems in homes is often hindered by the need for electrical contractors, as consumers are uncomfortable with electrical wiring and may find hiring one cost-prohibitive. Additionally, controllable light sources can have power interrupted when traditional wall-mounted light switches are turned off, disrupting remote control functionality.
Innovation Solution
A remote control device is designed to be mounted over an existing mechanical switch, allowing for control of electrical loads without accessing the switch's wiring. This device includes a base with a clamp arm and screw mechanism to secure itself to the switch, a user interface, and a wireless communication circuit to control load control devices, ensuring continuous power delivery to controllable light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional wall-mounted light switch is used to control power delivery, then power control functionality is achieved, but power to controllable light sources is interrupted when the switch is turned off, disrupting remote control functionality
Solution Approach 1:
A remote control device is introduced as an intermediary between the user and the controllable light source. The device includes a base that mounts to the existing mechanical switch and a control unit with wireless communication circuitry that transmits control signals to the light source, eliminating the need for direct wall switch operation while maintaining power control functionality
Solution Approach 2:
The control system is segmented into three independent components: the existing mechanical switch (which remains installed and provides power control), the remote control device (which mounts to the switch and provides wireless communication capability), and the controllable light source (which receives wireless commands). This segmentation allows the light source to remain powered while enabling remote control functionality
2Adaptability or versatility
If advanced load control devices are installed to replace mechanical switches, then advanced control functionality is achieved, but installation requires electrical wiring access and removal of existing switches, making the process complex and costly
Solution Approach 1:
The remote control device is designed to nest around the existing mechanical switch. The base of the remote control device fits over the paddle actuator of the installed switch, allowing the new functionality to be added without removing or replacing the existing switch. This nested configuration enables advanced control while maintaining the original switch installation
Solution Approach 2:
The remote control device serves as an intermediary layer between the existing mechanical switch and the user interface. It captures the switch's power control function and adds wireless communication capability, allowing advanced load control functionality to be achieved without complex wiring modifications
3Reliability
If the base is securely attached to the paddle actuator, then mounting stability is achieved, but the attachment mechanism becomes more complex with multiple components
Solution Approach 1:
The clamp arm is designed as a dynamic component that can be adjusted during installation. It features a movable jaw that can be positioned to accommodate different paddle actuator sizes and shapes, then secured in place. This dynamic adjustment capability provides secure mounting across various switch types without requiring a completely custom-designed attachment mechanism for each case
Solution Approach 2:
Multiple attachment functions are merged into a single integrated base assembly. The frame provides structural support, the clamp arm provides adjustable clamping force, and the screw provides secure fastening - all combined in one unit that attaches to the paddle actuator. This merging reduces the number of separate components the user must handle during installation

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.
