Secure Garage Door Remote Control via Authentication Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote controls for garage doors and similar closures pose a security risk as they can be accessed by thieves, allowing unauthorized opening of garage doors and potentially leading to unauthorized access to dwellings.
Innovation Solution
A secure remote control system that requires an authentication code, which can be entered via a keypad or obtained from an authorized user device through near field communication or short-wavelength radio, ensuring that the closure is only actuated if a valid code is provided, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control is made simple and easy to use, then ease of operation is improved, but security is worsened because unauthorized users can operate it
Solution Approach 1:
The remote control is segmented into two functional parts: a simple actuation selector element for easy operation and a separate authentication code input mechanism (keypad or wireless device interface) for security. This segmentation allows the actuation button to remain simple while the authentication process provides security verification.
Solution Approach 2:
An authentication code acts as an intermediary between the user and the actuation command. The code must be correctly entered or verified through a wireless device before the actuation command can execute, serving as a mediator that ensures authorized access while maintaining simple operation of the closure itself.
2Reliability
If authentication codes are required for every operation, then security is improved, but device complexity increases
Solution Approach 1:
The remote control system is designed to support multiple authentication methods (keypad entry and wireless device communication) and multiple actuation commands through a single unified interface. This multi-functionality reduces the need for separate devices for different security levels while maintaining comprehensive security coverage.
Solution Approach 2:
The system includes self-service capabilities where the remote control can store multiple authentication codes and automatically verify them without external intervention. The wireless communication interface allows the device to autonomously authenticate user devices and manage access control, reducing the need for complex external authentication systems.
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
Enhances security by ensuring that only authorized individuals can open the closure, reducing the risk of theft and unauthorized access to adjacent dwellings.
Implementation Method 1
using near field communication (NFC), e.g. FeliCa, transceiver
Implementation Method 2
using short-wavelength radio (SWR), e.g. Bluetooth or WIFI, transceiver

AI summary
Actuation of an access closure such as a garage door may be initiated by a remote control (RC) if a correct authentication code is received by the RC and/or if a designated authorization device such as a mobile phone is within near field communication transceiver range of the RC.
