Pedal-Actuated Releasable Security Shutter System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security window shutter systems do not allow for easy access during emergencies, as they lack a mechanism to move protective bars out of the way without compromising security.
Innovation Solution
A lock assembly that secures the shutter frame to the securing frame when closed, allowing it to be pivoted away upon user actuation, featuring pivotally coupled slat members that can switch between vertical and horizontal orientations for light and visibility control, and an actuation assembly using a pedal and linkage system to disengage the lock for emergency access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shutter frame is securely locked to the securing frame, then security against forced entry is improved, but ease of access during emergencies deteriorates
Solution Approach 1:
The lock assembly incorporates a pedal-actuated release mechanism that transforms the static locked state into a dynamically controllable state. When the pedal is depressed, it actuates the lock assembly to release the shutter frame, allowing quick emergency egress. This dynamic mechanism maintains secure locked operation during normal conditions while enabling rapid access when needed.
Solution Approach 2:
The system enables users to independently control the locking and unlocking of the shutter frame through the pedal mechanism. The pedal actuation directly engages the lock assembly to release the shutter frame without requiring external assistance or complex procedures, allowing occupants to quickly exit during emergencies.
2Reliability
If the shutter frame completely blocks the window, then security and privacy are improved, but light transmission and visibility deteriorate
Solution Approach 1:
The shutter frame is divided into multiple slat members that can be independently adjusted. This segmentation allows users to control the degree of light transmission and visibility by angling individual slats, while still maintaining overall security and privacy when needed.
Solution Approach 2:
The slat members are designed to be selectively pivotable between vertical and horizontal orientations. In the vertical orientation, they provide full security and privacy blocking. When pivoted to horizontal orientations, they allow light transmission and visibility while maintaining some degree of security. This dynamic reconfiguration resolves the contradiction between security and light transmission.

AI summary
A security shutter system for providing security against forced entry through a window. The security shutter system includes a securing frame being coupled to a wall of the structure around the window. A shutter frame is pivotally coupled to the securing frame and is selectively pivoted over the securing frame and secured to the securing frame over the window. The shutter frame is designed for inhibiting access into the structure through the window when the shutter frame is positioned over the window. A plurality of slat members are pivotally coupled to the shutter frame. Each of the slat members is selectively pivoted between a vertical orientation and a horizontal orientation. Each of the slat members controls light passage and visibility through the window.
