Window Safety Screen Cable Restraint System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window safety measures, such as window screens and guards, are often ineffective in preventing child falls through open windows, and existing window opening control devices can be disabled for improved ventilation, compromising safety.
Innovation Solution
A system featuring a safety screen frame with removable attachment to a window frame via a plurality of cables, providing secure attachment without tools and allowing for emergency egress, while maintaining ventilation and preventing falls even if the screen becomes loose or is improperly installed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional window screens are used, then ventilation is maintained, but child fall protection is insufficient
Solution Approach 1:
The safety system is divided into separate functional components: the existing window screen for ventilation and the cable-restraint system for fall protection. This segmentation allows each component to perform its specialized function effectively without compromising the other.
Solution Approach 2:
Cables serve as an intermediary element between the window frame and the screen frame, providing the restraining force needed to prevent child falls while allowing the screen to remain in place for ventilation purposes.
2Reliability
If window opening control devices are installed to limit window opening to less than 4 inches, then child fall protection is improved, but ventilation is reduced and devices can be disabled for greater ventilation
Solution Approach 1:
The invention extracts the fall protection function from the window opening control device, separating it from the ventilation control function. This allows the window to open fully for ventilation while the cable system independently prevents child falls.
Solution Approach 2:
The cable system serves multiple functions: it restrains the screen to prevent child falls, allows full window opening for ventilation, and cannot be easily disabled by users seeking greater ventilation.
3Reliability
If fall prevention window guards are installed to prevent child passes through windows, then child fall protection is improved, but aesthetic appeal is reduced and installation cost increases
Solution Approach 1:
The invention merges the fall protection function with the existing screen system by attaching cables to the screen frame, eliminating the need for separate window guards and reducing overall system complexity and cost.
Solution Approach 2:
Instead of installing guards across the entire window opening, the cable system applies restraint only at critical points where the screen frame attaches to the window frame, providing effective protection with minimal material and installation effort.
4Reliability
If safety screens are installed to provide fall protection, then child fall protection is improved, but improper installation may compromise safety
Solution Approach 1:
The cable system is pre-configured with attachment points on both the window frame and screen frame, guiding proper installation before the actual mounting process. This preliminary configuration ensures that even inexperienced installers can achieve adequate safety.

AI summary
A system for improved window fall prevention provides removable attachment of a window screen frame to a window frame. Systems according to the disclosure provide removable attachment of a window screen frame to an anchor positioned in the window frame by means of a plurality of cables. The cables attach to the screen frame or rest against an exterior portion of the screen frame at an exterior end, are threaded through the screen frame, and include on an interior end, opposite the exterior end, a releasable attachment to the window frame anchor. The releasable attachment may be between a loop of cable formed at the interior end and the window frame anchor, where the window frame anchor may be a T-screw.
