Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garage door locking systems are complex, require multiple actuators, and lack a streamlined integration with existing garage door openers, making them difficult to install and operate, especially in cases of power outages or encrypted systems.
Innovation Solution
A single actuator box with a rack and pinion gear system that integrates with existing garage door openers, using reed switches and magnetic activation for locking/unlocking, along with an optional solenoid for encrypted systems, and includes remote control and manual operation capabilities, with external LED indicators for status display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single actuator box with rack and pinion gear is used, then device complexity is reduced and ease of installation is improved, but the reliability of locking mechanism may be compromised
Solution Approach 1:
The patent combines the door opening/closing function and locking/unlocking function into a single actuator box. The motor-driven rack and pinion gear system performs both functions: moving the locking bar horizontally to lock/unlock, and vertically to open/close the door. This integration reduces the number of actuators from two to one, simplifying the system while maintaining reliability through the unified mechanical design.
Solution Approach 2:
The single actuator box is designed to perform multiple functions: it operates the locking bar for security locking/unlocking and simultaneously controls the door opening/closing mechanism. The motor and gear system are configured to provide both horizontal and vertical movement capabilities, making the actuator universal for both security and operational functions.
2Ease of operation
If integration with existing garage door openers is implemented, then ease of operation is improved, but adaptability to different systems may be reduced
Solution Approach 1:
The actuator box is designed with universal mounting capabilities that allow it to integrate with various existing garage door opener systems. The device can be installed on different door types and configurations, and the motor-driven mechanism can work with different opener brands and models, providing both ease of operation through integration and adaptability to different systems.
Solution Approach 2:
The locking system is designed as a separate, modular actuator box that can be independently installed and configured. This segmentation allows the device to be adapted to different existing garage door opener systems without requiring complete system replacement, enhancing both ease of operation and adaptability.
3Reliability
If manual operation capability is added for power outage scenarios, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking bar is designed with a manual operation handle that extends outward, allowing users to directly manipulate the locking mechanism during power outages. The mechanical design enables the locking bar to be moved manually to locked or unlocked positions without requiring electrical power, providing self-service capability that enhances reliability during failures.
Solution Approach 2:
The manual operation handle is pre-positioned and accessible on the locking bar, allowing immediate manual intervention when power is lost. The mechanical linkage is designed so that the handle can directly move the locking bar to the appropriate position, providing preliminary preparedness for power outage scenarios without adding complex emergency systems.

Function Achieved in This Case
Provides a simplified, easy-to-install garage door locking system that integrates door opening/closing and locking/unlocking functions, ensuring secure operation with power outage resilience and compatibility with encrypted systems, while offering clear external locking status indication.
Implementation Method 1
a magnetic external actuator built into the clip that mounts to the track to activate said CPU to activate said motor to move said rack gear with said pinion gear that is activated when said magnetic external actuator comes into alignment with one of said reed switches
Implementation Method 2
a first reed switch; a second reed switch; a third reed switch... activated when said magnetic external actuator comes into alignment with one of said reed switches
Implementation Method 3
a lighted indication LED that extends from the system to the outside of the garage door so that the locked state of the door can be seen from the outside

AI summary
A garage door locking system that includes a single actuator locking box that integrates with existing garage door openers to form a system that is easy to install and that can not only open and close the garage door, but provide a sequential locking/unlocking function. The actuator utilizes a rack and pinion gear that moves the locking bar in a horizontal position to lock or unlock. A lighted indication LED extends from the system to the outside of the garage door so that the locked state of the door can be seen from the outside. The actuator box utilizes LED lights that light up to show proper alignment of the magnet mounted on the track Specialized clips both tie down the power cords from the actuator box and provide a magnetic activation that indicates to the CPU to move the bar to lock and also indicate the door position at all times.
