Retrofit Mesh Network Switches for Electrical Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home automation systems face challenges in retrofitting existing wired electrical systems, requiring complex wiring and costly rewiring for multi-way switch configurations, and often consume excessive power due to constant communication needs, limiting their energy efficiency and flexibility.
Innovation Solution
A power control system that includes a master switch with a physical SPDT relay and analog control circuit, capable of retrofitting into existing electrical infrastructure, allowing for local and remote control through a Bluetooth Low Energy network, with capacitive touch activation and self-organizing mesh networking, enabling communication between switches without additional wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional home automation systems are installed in existing electrical infrastructure, then automation functionality is achieved, but complex wiring and costly rewiring are required
Solution Approach 1:
The patent replaces traditional mechanical/wired communication between switches with wireless communication technology. Each switch includes a wireless communication module that enables data exchange without physical wiring connections, thereby eliminating the need for complex rewiring while maintaining multi-way switch functionality.
Solution Approach 2:
The patent creates a universal switch device that can function in multiple configurations (single-way, two-way, multi-way) without requiring different hardware or wiring arrangements. The wireless communication protocol automatically adapts to the network topology, allowing the same device to serve various switching configurations.
2Ease of operation
If constant communication is maintained for automation control, then remote control capability is achieved, but excessive power consumption occurs
Solution Approach 1:
The patent implements periodic communication instead of constant communication. Switches transmit status information and receive control commands only when needed (upon user interaction or system events), allowing the system to enter low-power states during idle periods while maintaining full remote control functionality when activated.

AI summary
Systems and methods that can be retrofitted into an existing wired electrical system replacing existing switches whether as a standalone single switch or part of a multi-way switch configuration that can be controlled locally nominally by touch, controlled remotely by a remote, or controlled remotely by a computer. The systems and method provide that the switches establish a local network allowing for retrofit or construction of a structure or facility with electrical system automation without the need for additional wiring.
