Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home automation systems do not fully leverage the capabilities of smart phones and tablets, particularly near field communication (NFC), for more robust control systems.
Innovation Solution
A system that enables control of home automation devices using a portable electronic device with an NFC interface, which reads information from an NFC tag on a keypad, opens a control application, and transmits control signals to the home automation network, allowing users to control devices through a graphical representation of the keypad on their device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC technology is integrated into home automation control systems, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent uses NFC tags as intermediary elements that store control information and network addresses. When a user brings a portable device near a control point, the NFC tag mediates the connection by providing stored credentials and configuration data, enabling seamless authentication and device pairing without complex manual setup procedures
Solution Approach 2:
The system performs preliminary actions by pre-configuring NFC tags with control point identifiers, network addresses, and authentication credentials during installation. This preliminary setup eliminates the need for complex real-time configuration when users later interact with the system, as all necessary information is already prepared and stored in the NFC tags
2Adaptability or versatility
If multiple control functions are integrated into a single portable device, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing the portable electronic device to perform multiple control functions through a single integrated application. The control application can authenticate users, retrieve control point information from NFC tags, display graphical interfaces, and transmit control signals across different device types (lighting, audio, HVAC), making one device replace multiple specialized controllers

Data Source
AI summary
A system in which a portable electronic device communicates with a keypad including a near field communication (NFC) tag in order to establish remote control of a controllable residential device over a home automation network. Upon placing the portable electronic device near the keypad, a control application running on the portable electronic device is launched and a graphical representation of the keypad is displayed on the portable electronic device. The portable electronic device then provides remote control of the controllable residential device over the home automation network. The portable electronic device may additionally provide expanded control options for the controllable residential device.
