Convex Tactical Mirror for Concealed Room Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Military and law enforcement personnel face challenges when entering and clearing buildings, as they are vulnerable when viewing room interiors through doorways, necessitating a safer method to assess threats without exposure.
Innovation Solution
A man-portable tactical mirror system featuring a convex mirror that can be rapidly deployed and affixed to a door, providing a wide-angle view of the room interior from a concealed position, allowing team members to assess threats safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If team members view room interiors through doorways to assess threats, then they can identify potential dangers, but they become vulnerable to attacks from persons within the room
Solution Approach 1:
A convex mirror is introduced as an intermediary device that allows team members to view the room interior indirectly. The mirror is positioned outside the room on the door or adjacent surface, reflecting the interior space so team members can assess threats without physically exposing themselves by looking through the doorway opening.
Solution Approach 2:
The solution transitions from direct linear viewing through the doorway to indirect viewing via reflection. By using the mirror's reflective surface, team members gain a side-angle view of the room interior from a concealed position, effectively changing the dimensional approach to threat assessment.
2Object-affected harmful factors
If team members remain in concealed cover positions outside rooms, then they reduce vulnerability to attack, but they lose the ability to view room interiors and assess threats
Solution Approach 1:
The convex mirror serves as the intermediary that bridges the gap between concealed positioning and threat assessment. Team members remain in protected cover positions while the mirror, positioned on or near the door, transmits visual information from the room interior to the observer's eyes.
Solution Approach 2:
By using the mirror's reflective geometry, the system enables viewing from a different spatial dimension - team members observe the room interior from a side angle rather than directly through the doorway, maintaining concealment while gaining intelligence.
3Loss of information
If a convex mirror is used to provide wide angle viewing, then team members can assess the entire room interior, but the mirror device becomes larger and harder to carry and deploy rapidly
Solution Approach 1:
The use of a convex (curved) mirror surface provides a wide-angle field of view that captures more of the room interior compared to a flat mirror of the same size. This curvature allows comprehensive threat assessment with a smaller, more portable device that can be rapidly deployed and concealed.
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
Enables entry team members to safely view room interiors before entering, reducing vulnerability and enhancing tactical efficiency during building clearance operations.
Implementation Method 1
The mirror surface is preferably generally convex to provide a wide angle field of view
Implementation Method 2
The mounting surface includes at least one generally planar portion adapted for adhesively securing the mirror device to a vertical door surface

AI summary
A tactical mirror system includes a convex mirror that may be rapidly deployed and adhesively affixed to a room entry door to provide a room entry team member with a view of the room interior from a concealed cover position outside the room adjacent to the doorway is disclosed. A rip-cord is affixed to allow the user to peel away a protective layer thereby exposing an adhesive coated surface thereby allowing for rapid affixation of the mirror. A pair of diametrically opposed notches and a resilient transversely disposed band that function to allow the mirror device to be removably mounted to a baton to allow a room entry team member to manually extend and position the mirror. A plurality of mirrors may be provided and configured for compact nested storage thereby providing the user with a plurality of deployable mirror devices.
