TV Remote Security Control With IR-to-Network Signal Bridging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home security systems are not compatible with conventional IR remote controls, limiting their interaction to key fobs, which may not be readily available when needed.
Innovation Solution
A system that enables interaction with a home security system using a television remote control, converting IR signals into electronic signals via a server and wide-area network to control security functions and display status on a TV.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key fob is used to control the security system, then the system can be conveniently controlled wirelessly, but the key fob may not be within reach when the user is inside the home watching TV
Solution Approach 1:
The TV remote control is designed to serve multiple functions: controlling the television and controlling the security system. By programming the remote with both TV codes and security system codes, a single device provides universal control across different locations and contexts, eliminating the need for separate key fob and TV remote.
Solution Approach 2:
The patent introduces an intermediary device (the TV remote control) that bridges between the user and the security system. The remote acts as a mediator that translates user commands into security system actions, allowing control without direct physical contact with the security system or key fob.
2Ease of operation
If a TV remote control is used to interact with the security system, then convenient control is achieved, but the IR signals from the remote are incompatible with the home security system
Solution Approach 1:
The patent changes the signal parameters by programming the TV remote control with specific security system codes and protocols. The remote is configured to transmit IR signals at specific frequencies, durations, and patterns that match the security system's requirements, transforming an incompatible device into a compatible one through parameter adjustment.
Solution Approach 2:
The patent creates a copy of the key fob's functionality within the TV remote control. By programming the remote to replicate the wireless transmission capabilities and command structure of the original key fob, the system enables control through a familiar device without requiring changes to the security system itself.
3Reliability
If the security system uses a dedicated keypad/display device, then direct communication is established, but the device is not portable and may not be accessible in all locations
Solution Approach 1:
The patent replaces the mechanical/physical keypad and display device with a wireless remote control system. Instead of requiring physical contact with buttons and visual inspection of displays mounted in fixed locations, the system uses wireless IR signal transmission and reception, allowing control and monitoring from any location within range.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient control and monitoring of home security systems using a TV remote, allowing for remote control of security features and visual display of system status on a television.
Implementation Method 1
Most TV remote controls generate infra-red (IR) signals that are incompatible with home security systems
Data Source
AI summary
A method and apparatus is described for interacting with a security system using a television remote control. Commands sent by the remote control are received by an auxiliary interface device, which then provides the commands to a security system controller either directly, via a local-area network, or via a wide-area network and server. Status and acknowledgement messages are transmitted from the security system controller to the auxiliary device, whereupon they are provided to and displayed by a television in the form of a security dashboard.
