Garage Screen Door With Inverted L-Track and Spring Spool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garage door systems lack a cost-effective, safe, and convenient method for incorporating a supplemental single panel garage door with a centrally positioned screen door that is both durable and aesthetically appealing.
Innovation Solution
A garage screen door system featuring inverted L-shaped primary and secondary tracks, a single panel garage door with a centrally positioned rectangular portal, a flexible screen door with a spring-loaded spool and magnetic closure, and a lifting assembly with rollers and pulleys for easy operation, along with a beam deflector for safety, to facilitate movement and minimize lifting strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a supplemental single panel garage door with a centrally positioned screen door is added to an existing garage door system, then the functionality and convenience are improved, but the device complexity and cost increase
Solution Approach 1:
The screen door is nested within the secondary garage door panel, with the screen door assembly fitting inside the larger door structure. The flexible screen is contained within a housing that is integrated into the door rail system, creating a nested configuration that adds functionality without proportionally increasing overall system complexity
Solution Approach 2:
The secondary garage door serves multiple functions: it acts as a structural door panel, contains the screen door assembly, provides the lifting mechanism attachment points, and integrates with the existing primary door track system. This multi-functionality reduces the need for separate components
2Ease of operation
If a flexible screen door with spring-loaded spool and magnetic closure is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The magnetic closure system provides automatic latching when the screen door is closed, eliminating the need for manual locking. The spring-loaded spool automatically reels in the flexible screen when the door closes, and the system self-regulates the screen tension without user intervention
Solution Approach 2:
The magnetic closure replaces traditional mechanical latches or locks with magnetic attraction forces. The spring-loaded spool mechanism converts the flexible screen into a retractable element, replacing what would otherwise require a rigid framed screen door
3Reliability
If the screen door width is made greater than the portal width to ensure coverage, then the reliability is improved, but the device complexity and potential interference increase
Solution Approach 1:
The flexible screen can dynamically adjust its position and shape as it is reeled in and out. When the screen door is in the closed position, the flexible screen extends beyond the portal edges to ensure complete coverage, and when opened, it retracts into the housing, adapting its configuration based on operational state
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
The system provides a safe, convenient, and cost-effective solution for a supplemental single panel garage door with a centrally positioned screen door, ensuring durability and ease of use while minimizing interference between primary and secondary garage doors.
Implementation Method 1
The housing has a spring loaded spool. The spool receives the flexible screen.
Implementation Method 2
The first vertical door rail and the vertical support have magnets. In this manner the flexible screen is maintained in a closed orientation.
Implementation Method 3
The lifting assembly includes a major pulley. The lifting assembly includes secondary pulleys. The pulleys guide the movement of the screen door when lifting and lowering.
Implementation Method 4
The lifting assembly also includes a coil spring. The coil spring couples the secondary pulleys with respect to the horizontal section of the secondary track adjacent to the front opening. In this manner the strength needed to lift and lower the secondary garage door is minimized.

AI summary
Each of two tracks are in an inverted L-shaped configuration and have a vertical section and a horizontal section. A single panel garage door is mounted for movement in the tracks between a closed orientation between the vertical sections and an open orientation between the horizontal sections. A rectangular portal is positioned within the garage door. Major screening in the garage door is at locations remote from the portal. A screen door within the portal is moveable between a closed orientation over the portal and an open orientation remote from the portal.
