Retrofit Remote Switch Control Without Rewiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load control systems require electrical rewiring and replacement of mechanical switches for advanced features, making them inaccessible for average consumers.
Innovation Solution
A remote control device that can be mounted over an existing mechanical toggle switch, allowing for wireless control of electrical loads without rewiring, using a base portion and intensity adjustment actuator to secure the toggle actuator in the on position and transmit control signals wirelessly to a controllable light source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical toggle switches are replaced by advanced load control devices, 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 toggle switch, nesting the new technology within the old infrastructure. This allows the advanced load control device to utilize the existing electrical wiring and switch mounting location, eliminating the need for complex rewiring while providing dimming and energy savings features
Solution Approach 2:
The remote control device acts as an intermediary between the user and the electrical load. Instead of replacing the switch itself, the remote control device communicates wirelessly with the load control device, mediating the control function without requiring direct electrical connection changes at the switch location
2Use of energy by moving object
If mechanical toggle switches are replaced by load control devices, then energy control is improved, but ease of operation deteriorates
Solution Approach 1:
The system allows the consumer to perform the installation themselves without requiring an electrical contractor. The remote control device is designed to be mounted over the existing switch by the end user, and the load control device in the fixture is configured through simple wireless pairing, making the entire system self-installable while providing energy control capabilities
3Ease of operation
If the toggle actuator is left accessible, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The remote control device is mounted over the toggle actuator in a position where it can maintain the actuator in the on position while preventing the user from manually switching it to the off position. This extracts the manual off capability from the physical switch while maintaining wireless control functionality, ensuring the load remains reliably controlled through the remote device

AI summary
A remote control device may be configured to be mounted over the toggle actuator of a light switch and to control a load control device via wireless communication. The remote control device may include a base portion and a rotating portion supported by the base portion so as to be rotatable about the base portion. The remote control device may include a control circuit and a wireless communication circuit. The control circuit may be operably coupled to the rotating portion and to the wireless communication circuit. The control circuit may be configured to translate a force applied to the rotating portion of the remote control device into a control signal and to cause the communication circuit to transmit the control signal to the load control device.
