Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home automation systems require products to be powered with electricity for configuration, and locating and pairing multiple products within a network is cumbersome, especially before installation.
Innovation Solution
A method utilizing a mobile device with a microcontroller and NFC/RFID chip reader for bidirectional communication to configure and pair home automation products before power-up, allowing configuration and parameterization without electricity and facilitating product identification and pairing within a home automation network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If configuration is carried out via wireless link (hertzian waves) as described in prior art, then configuration can be performed remotely, but the products must be supplied with electricity for configuration to occur
Solution Approach 1:
The patent introduces an intermediary device (portable controller with NFC/RFID interface) that mediates between the user and the home automation products. This intermediary can store configuration data and transfer it to products via near-field communication, enabling configuration before the products are connected to power supply. The intermediary acts as a buffer that decouples the configuration operation from the power supply requirement.
2Adaptability or versatility
If multiple products are present in the network, then the system functionality is enhanced, but it becomes impossible to locate and identify specific products for configuration from the installer's location
Solution Approach 1:
The patent employs visual indicators (LED lights or display elements) on each home automation product that change color or illuminate to indicate the product's identity, status, or selection state. This allows the installer to visually identify and locate specific products among multiple devices in the network, even from a distance or without accessing each product's interface individually.
3Productivity
If configuration is performed before installation, then installation efficiency is improved, but the products must be accessible and powered for configuration
Solution Approach 1:
The patent enables preliminary configuration actions to be performed on home automation products before they are installed in their final locations and before they are connected to power supply. The portable controller allows users to pre-configure product parameters, settings, and pairings by bringing the controller close to each product during the installation process, rather than requiring products to be powered and networked in advance.
