Secure Exit Shade With Status Indicators And Emergency Instructions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure exit shades for classroom windows during lockdowns fail to provide emergency instructions to teachers and status information for emergency personnel, are flammable, difficult to install, and often break or fall apart, leading to inefficiencies in emergency response.
Innovation Solution
A secure exit shade made of powder-coated metal, folded into five sections with heavy-duty magnets and small hinges, featuring a color wheel for status indication, a plastic pocket for instructions, and a 'EXIT' display, which can be easily bolted to the door and pulled down to block intruder access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional opaque materials are used for secure exit shades, then visual access is blocked, but emergency instructions and status information cannot be provided to teachers and emergency personnel
Solution Approach 1:
The shade is divided into multiple sections: opaque sections for blocking visual access and transparent sections for displaying emergency instructions and status information. This segmentation allows the shade to simultaneously provide both visual blocking and information transmission functions.
Solution Approach 2:
Different portions of the shade have different optical properties - some areas are opaque to block views, while other areas are transparent to allow information display. This local differentiation of material properties enables the shade to fulfill multiple functions in different locations.
2Ease of operation
If magnetic latching assemblies are used for easy shade deployment, then installation is simplified, but space for emergency instructions is reduced
Solution Approach 1:
The magnetic latching assembly is extracted and positioned in a header component separate from the main shade body. This extraction allows the shade to have sufficient area for emergency instructions while maintaining the ease of magnetic deployment.
Solution Approach 2:
The latching mechanism is moved to a different spatial dimension (the header above the window) rather than occupying space within the shade panels themselves. This dimensional relocation preserves instruction space while maintaining operational ease.
3Ease of manufacture
If flammable materials are used for shade construction, then ease of manufacture is improved, but safety during fire emergencies is compromised
Solution Approach 1:
The shade uses a composite construction combining non-flammable materials (metal frame, plastic components) with fire-resistant treatments or coatings. This composite approach maintains manufacturability while eliminating fire hazards.
Solution Approach 2:
The material properties are changed from flammable to non-flammable through material substitution or fire-retardant treatment. This parameter change in material composition eliminates fire safety risks while preserving the ease of manufacture through standardized non-flammable materials.
4Productivity
If simple attachment methods are used for shade installation, then installation speed is increased, but reliability of attachment is reduced
Solution Approach 1:
The attachment system merges multiple functions: magnetic latching for quick attachment, mechanical hinges for stable connection, and overlapping panels for secure fit. This combination of attachment methods achieves both rapid installation and high reliability.
Solution Approach 2:
The shade components are pre-assembled with attached panels and pre-positioned magnetic latches before installation. This preliminary assembly reduces installation time while ensuring proper alignment and secure attachment through pre-configured connection points.

AI summary
A shade adapted for covering a classroom viewing window and assisting with compliance with emergency protocol during an emergency is disclosed. The shade may include a plurality folds connected to each other by a plurality of hinges configured to cover a classroom viewing window. Emergency related information and status indicators may be revealed upon the unfolding of the shade to assist teachers, school officials, police, and others to comply with established school emergency protocol. The shade further fulfills the requirement that the classroom viewing window be covered during an emergency lockdown. The shade may function as a standard “Exit” sign during non-emergency time. Another shade may include a case holding a material portion with handles that enable the shade to be moved up and down.
