Modular Smart Switch Retrofitting Existing Electrical Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted switches and outlets lack advanced features and require new wiring for installation, limiting their ability to integrate with home automation, security, and climate control systems without compromising the integrity of the wall space.
Innovation Solution
A smart switch device with a modular design that fits within existing electrical boxes, featuring a switch module, a control panel with user interface, and power line communication capabilities, allowing for control of multiple electrical loads and integration with security and automation systems without the need for new wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mechanical switches are replaced with electronic alternatives to add functionality, then home automation and security features are improved, but installation complexity and wiring requirements increase
Solution Approach 1:
The device is divided into separate functional modules: a control panel with user interface and a switch module with electronic components, allowing independent installation and replacement without complete system replacement
Solution Approach 2:
The control panel is designed with a size sufficient to fully cover the open front of multi-gang electrical boxes, enabling the same device to be used with single-gang or multi-gang boxes without leaving uncovered portions, thus providing universal applicability
2Ease of manufacture
If smart switches are installed in existing electrical boxes, then retrofit capability is improved, but the control panel size must be reduced to fit within the box
Solution Approach 1:
The device separates the control panel from the switch module, allowing the control panel to extend beyond the electrical box while the compact switch module fits within the box constraints
Solution Approach 2:
The control panel and switch module are combined into a single integrated device that can be installed in existing electrical boxes, merging the benefits of full-coverage control panels with compact retrofit-capable dimensions
3Adaptability or versatility
If a control panel is sized to fully cover multi-gang electrical boxes, then versatility across different box types is improved, but the device may not fit within single-gang boxes
Solution Approach 1:
The device is segmented into a compact switch module that fits within any electrical box and a control panel that can extend beyond the box to provide full coverage when installed in multi-gang boxes
Solution Approach 2:
The device provides dynamic adaptability by being usable with either single-gang or multi-gang electrical boxes, adjusting its effective coverage area based on the installation context without requiring different device versions

AI summary
An electrical switch device features a switch module housing that fits at least partially within an in-wall electrical box. The housing contains electrically controlled switches and has line and neutral contacts carried for each of the electrically controlled switches to enable connection of a different respective load circuit across each electrically controlled switch. A control panel is mountable over an open front of the in-wall electrical box and the housing therein, and has a user-interface for operation of the switch module to control the electrically controlled switches and connected loads. The control panel is sized to fully cover the open front of a multi-gang electrical box, whereby the same switch module and control panel are usable with either a single-gang or multi-gang electrical box without leaving any portion of the open front of the single-gang or multi-gang electrical box uncovered by said control panel.
