Sliding Panel Ballistic Window Assembly for Tool-Free Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional attack-resistant window assemblies require access to the unsafe 'attack side' for pane installation and replacement, posing safety risks and necessitating tool use, while they may not fully protect against peripheral bullet entry points.
Innovation Solution
A window assembly design featuring a sliding rear panel that allows for tool-free insertion and removal of attack-resistant panes from the protected side, incorporating a peripheral armor portion to prevent bullet escape through the pane's edges, and utilizing a base frame with armor panels for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional window assembly hardware is used, then the pane can be secured firmly, but the pane requires access to the attack side for installation and removal
Solution Approach 1:
The patent inverts the conventional operation direction by enabling pane installation, removal, and replacement to be performed exclusively from the protected side. The hardware configuration allows the pane to be manipulated from the safe side, eliminating the need for personnel to access the dangerous attack side during maintenance operations.
2Ease of operation
If conventional pane securing hardware is used, then the pane is firmly attached, but tool use is required for installation and removal
Solution Approach 1:
The hardware system is segmented into distinct functional components: a frame member with opening, a movable plate that slides to secure the pane, and a pane itself. This segmentation allows the movable plate to be operated independently from the frame, enabling tool-free manipulation while maintaining secure attachment when engaged.
3Reliability
If standard pane protection is used, then central bullet resistance is provided, but peripheral bullet entry points are not protected
Solution Approach 1:
The patent merges the pane protection function with the frame structure by integrating a peripheral armor portion into the base frame. This armor portion extends around the peripheral edges of the pane, combining edge protection with the main pane structure to create comprehensive ballistic resistance that addresses both central and peripheral penetration risks.
4Productivity
If quick pane replacement is implemented, then maintenance time is reduced, but safety during replacement may be compromised
Solution Approach 1:
The hardware configuration enables self-service pane replacement from the protected side. The movable plate can be滑动 to release and secure the pane without requiring tools or access to the attack side, allowing rapid maintenance operations to be performed safely by personnel remaining in the protected zone.

AI summary
An attack-resistant window assembly that can be easily maintained without requiring the use of tools. The attack-resistant window assembly includes a slidable plate for securing the attack-resistant pane into the window assembly. The window assembly also has ballistic-resistant armor around the peripheral sides of the ballistic-resistant pane to prevent bullets from exiting the peripheral sides of the ballistic-resistant pane and coming into the space on the protected side of the window assembly.
