Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load control systems require electrical work to replace standard mechanical switches with advanced devices like dimmer switches, making it difficult for average consumers to install these systems without professional assistance.
Innovation Solution
A remote control device is designed to be mounted over an existing mechanical switch, allowing for control of electrical loads without the need to access or rewire the switch's electrical wiring. The device includes a base and a control unit with a wireless communication circuit that can transmit control signals in response to user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard mechanical switches are replaced with advanced load control devices like dimmer switches, then load control capability is improved, but installation complexity increases requiring electrical work and professional assistance
Solution Approach 1:
The remote control device is nested over the existing mechanical switch, with the frame fitting around the switch and the control unit housed within the base structure. This allows the advanced load control device to be installed without removing or replacing the existing switch, eliminating the need for electrical wiring work while maintaining load control capability.
Solution Approach 2:
The mechanical switch acts as an intermediary between the power source and the load, while the remote control device serves as a mediator that wirelessly controls the load. The mechanical switch remains in place to provide physical circuit breaking capability, while the remote device provides wireless control functionality without requiring electrical installation.
2Adaptability or versatility
If mechanical switches are replaced with load control devices, then power delivery control is improved, but ease of operation deteriorates requiring skilled installers
Solution Approach 1:
The remote control device is designed for self-service installation by consumers. The mechanical switch remains in place and continues to function, while the remote device is simply mounted over it using the frame and biasing member mechanism, requiring no electrical wiring skills. The device serves itself by utilizing the existing switch infrastructure.
Solution Approach 2:
The remote control device provides multiple functions: wireless control of the load, visual indication of switch position through the paddle, and maintains the circuit breaking capability of the mechanical switch. This multi-functionality allows advanced power delivery control while keeping installation simple and accessible to consumers.
3Adaptability or versatility
If electrical wiring is accessed to install load control devices, then load control functionality is improved, but safety risks increase for average consumers
Solution Approach 1:
The wireless control functionality is extracted from the electrical wiring system and placed in a separate remote control device that operates independently. The mechanical switch remains connected to the electrical system and continues to provide safe physical circuit control, while the remote device provides additional control capability without requiring consumers to access or work with electrical wiring.
4Shape
If existing mechanical switches are covered with remote control devices, then aesthetic appeal is improved, but mounting complexity increases
Solution Approach 1:
The biasing member provides a dynamic mounting mechanism that automatically adjusts to fit the mechanical switch. When the control unit is inserted into the base, the biasing member engages with the mechanical switch and applies outward force against the stop, securely holding the assembly in place. This dynamic mechanism simplifies mounting while maintaining a clean, integrated aesthetic appearance.

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 include a control unit and a base that may be configured to be mounted over a paddle actuator of an installed mechanical switch. The base may include a frame, a biasing member, and/or a ribbon portion. The frame may be configured to secure the remote control device thereto. The frame may define a rear surface that is configured to abut a bezel of the mechanical switch. The biasing member may be configured to engage a rear surface of a faceplate of the mechanical switch. The ribbon portion may be configured to attach the biasing member to the frame. The ribbon portion may be configured to extend through a gap between the bezel and the faceplate.
