Intelligent Switch for Multi-Way Circuit Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-way electrical switching systems require extensive replacement of hardware and are prone to failure due to dependence on continuous communication, making them unsuitable for applications where reliability and security are critical, especially in buildings with antique or non-standard fixtures.
Innovation Solution
An intelligent switching apparatus that actsuates a conventional mechanical switch, allowing remote toggling of a multi-way circuit by replacing only one switch, which includes a logic unit and computer system to detect and manage system state, ensuring manual operation remains functional even if the intelligent switch fails, and communicates wirelessly for remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If existing multi-way electrical switching systems are replaced with intelligent switching systems, then remote control capability and advanced features are improved, but hardware replacement extent and system complexity increase
Solution Approach 1:
The patent extracts the intelligence from a complete system replacement and concentrates it in a single standalone intelligent switch device. This intelligent switch can be installed in existing multi-way circuits without requiring replacement of other switches, thereby achieving remote control capability while minimizing hardware replacement extent.
Solution Approach 2:
The intelligent switch is designed to work with existing multi-way switching geometries (three-way, four-way, etc.) without requiring modification of the overall system architecture. It can replace just one switch in the chain and maintain compatibility with conventional wiring, making the solution universally applicable to various existing installations.
2Extent of automation
If intelligent switching systems depend on continuous communication, then remote control functionality is improved, but system reliability deteriorates
Solution Approach 1:
The intelligent switch includes local intelligence and decision-making capability within the device itself, rather than relying entirely on continuous external communication. The switch can autonomously process control signals and maintain operation even when communication is interrupted, providing a buffer against communication failures and improving overall system reliability.
3Extent of automation
If conventional switches are replaced with smart switches requiring extensive hardware changes, then automation features are improved, but ease of installation and compatibility with antique fixtures deteriorate
Solution Approach 1:
The patent extracts the smart functionality into a single replaceable unit that interfaces with existing wiring configurations. This allows the intelligent features to be added without modifying antique fixtures or requiring extensive rewiring, as the smart switch adapts to the existing circuit topology.
Solution Approach 2:
The intelligent switch is designed to accommodate various existing switching configurations (three-way, four-way, single-pole) and can be installed in different positions within the circuit chain. This universality enables compatibility with antique fixtures and diverse existing installations without requiring system-wide replacement.

AI summary
An intelligent electrical switch comprising a conventional mechanical switch connected to a computer system in communication with an external device and receiving instructions therefrom. The switch may be installed in an existing circuit to replace one switch in a multi-way wiring geometry, and includes a sensor detecting current on the neutral line. By determining the circuit state, the switch can determine whether, when instructions are received wirelessly to power the circuit on or off, the mechanical switch element should be toggled.
