Virtual Window Door with Hardened Core and Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Schools face the challenge of protecting students from intrusions, as classroom doors are often the last line of defense, and existing security measures do not adequately address the threats of fire, bullets, and unauthorized entry while providing real-time observation and communication.
Innovation Solution
A dual-view virtual high-security window system integrated into doors, comprising cameras, digital displays, a hardened core, and laminate layers, which creates a virtual window for observation and communication, while being resistant to fire, bullets, and intrusion, and includes features like facial recognition, emergency alerts, and deterrents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a classroom door is made solid and secure to prevent intrusion, then security against unwanted entry is improved, but the ability to observe the exterior environment in real-time deteriorates
Solution Approach 1:
The patent uses cameras to capture visual information from the exterior environment and displays it on digital screens mounted on the interior side of the door. This creates a visual copy of the external scene, allowing occupants to observe their surroundings without physically opening the door or compromising its security integrity.
Solution Approach 2:
The patent introduces cameras and digital displays as intermediary devices between the occupants and the exterior environment. These intermediaries transmit visual information through the solid door structure, enabling observation without creating physical openings that would compromise security.
2Reliability
If a solid core door is used to provide security protection, then resistance to intrusion and fire is improved, but the ability to provide natural light and visual connection deteriorates
Solution Approach 1:
The patent uses digital displays to create a visual copy of the external environment, compensating for the lack of natural light transmission through the solid door. The cameras capture external scenes and reproduce them on screens, providing visual connection without requiring light to pass through the door material.
3Loss of information
If cameras and digital displays are added to create a virtual window, then real-time observation capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent integrates multiple functions into the door assembly: the camera system provides both security monitoring and environmental observation, the digital displays serve as both information sources and potential communication interfaces, and the intercom system enables two-way communication. This multi-functionality reduces the need for separate systems and minimizes overall device complexity.
4Strength
If high-performance laminate material is used to laminate and encapsulate components, then durability and resistance to fire and bullets are improved, but manufacturing complexity increases
Solution Approach 1:
The patent uses high-performance laminate material to composite the various door components together. This laminate structure provides enhanced strength, fire resistance, and bullet resistance while encapsulating the electronic components (cameras, displays, intercom) in a protected environment. The composite construction integrates structural and protective functions in a single manufacturing process.

AI summary
A high security two-way virtual cross-barrier observation and communication device has a mounting frame with a hardened core, a pair of digital displays, and a pair of cameras. The mounting frame may correspond to a typical interior door of a building or a relevant component of a vehicle, aircraft, or other relevant application. The hardened core is bullet-resistant and fire-resistant to protect occupants of a protected space from harm. The digital displays and cameras are positioned on opposing sides of the mounting frame, each camera transmitting a live video feed to the opposing display, creating the appearance of a window while protecting occupants. The digital displays may be used to display any desired information. An emergency protocol may be activated to communicate with emergency services. A plurality of laminate layers bond and encapsulate the displays and cameras to the hardened core, forming a rugged, self-contained unit with no moving parts.
