Garage Door Controller Wireless Relay Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garage door remote control systems are limited to a range of about 50 feet, preventing users from controlling or determining the status of garage doors from farther distances, leading to potential issues like forgotten closed garage doors.
Innovation Solution
A garage door controller with wireless communication capabilities, allowing remote operation and status monitoring via WiFi or cellular networks, integrated with a camera for visual confirmation and safety sensors for enhanced safety features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional remote control devices are used to control garage doors, then the control function is achieved, but the control range is limited to about 50 feet
Solution Approach 1:
The patent introduces a relay server as an intermediary component between the remote control device and the garage door opener. The relay server receives control signals from the remote device via WiFi network and forwards them to the garage door opener, enabling control beyond the direct 50-foot range limitation. This mediator approach allows the system to overcome the inherent range constraint while maintaining control functionality.
2Loss of information
If conventional remote control devices are used, then basic control is possible, but status monitoring capability is lost
Solution Approach 1:
The patent implements a feedback mechanism where the garage door opener continuously reports its operational status (open/closed state) back to the relay server, which then transmits this information to the remote control device. This feedback loop enables the user to monitor the door status remotely without adding significant complexity to the overall system, as the status information is already available at the opener and is simply being relayed back to the user.
3Length of stationary object
If wireless communication modules are added to enable remote control, then control range is extended, but device complexity increases
Solution Approach 1:
The patent extracts the wireless communication functionality from the garage door opener itself and places it in a separate relay server component. The opener maintains its simple wired design with basic open/close control, while the complex WiFi communication hardware and protocol handling are isolated in the relay server. This separation allows the control range to be extended without increasing the complexity of the opener device.

AI summary
Methods for replacing a first garage door controller with a second garage door controller can include electrically decoupling the first garage door controller from a first wire that is electrically coupled to the garage door opener. Methods can include electrically decoupling the first garage door controller from a second wire that is electrically coupled to the garage door opener. Methods can also include electrically coupling the second garage door controller to the first wire and electrically coupling the second garage door controller to the second wire. Methods can even include communicatively coupling the second garage door controller to an Internet router to thereby communicatively couple the second garage door controller to a wireless network.
