Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security devices for temporarily obstructing passages, such as corridors or windows, are cumbersome, time-consuming to install, and expose security personnel to risks during installation, as they require mechanical attachment and complex locking systems, lacking a quick and easy solution for rapid intervention.
Innovation Solution
An autonomous protection device featuring a telescopic bar that can be easily extended and locked between wall surfaces, equipped with removable obstruction elements like rigid slats or a flexible screen, utilizing a pneumatic jack for quick deployment and retraction, allowing adaptation to existing walls without modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical attachment methods are used to secure anti-burglary grids, then the device provides secure blocking, but the installation time increases and device complexity increases
Solution Approach 1:
The patent replaces complex mechanical attachment systems with a pneumatic jack mechanism. The jack uses pneumatic pressure to automatically extend the telescopic bar and engage blocking surfaces, eliminating the need for manual mechanical fastening operations and reducing installation time while maintaining secure blocking.
Solution Approach 2:
The device performs its own installation through the pneumatic jack system. Once positioned between blocking surfaces, the jack automatically extends and locks the bar without requiring external mechanical attachment tools or complex manual procedures, making the installation process self-contained and rapid.
2Reliability
If heavy grids with complex locking systems are used, then the device provides secure protection, but the ease of operation decreases and handling becomes difficult
Solution Approach 1:
The device is divided into modular components: a telescopic bar, removable obstruction elements, and a pneumatic jack system. This segmentation allows each component to be optimized independently - the bar provides structural strength, the obstruction elements can be quickly attached or removed, and the jack provides easy actuation, overall improving handling ease while maintaining protection.
Solution Approach 2:
The pneumatic jack system replaces heavy mechanical locking mechanisms with a lightweight pneumatic actuation system. The compressed air cartridge provides sufficient force to extend and lock the telescopic bar without requiring heavy mechanical linkages, complex springs, or multiple manual steps, thereby improving ease of operation while maintaining secure protection.
3Ease of operation
If rolling shutter systems with mechanical fixing are used, then the device provides obstruction capability, but the installation complexity increases and time required increases
Solution Approach 1:
The patent replaces the mechanical fixing systems of rolling shutter devices with a pneumatic actuation system. The telescopic bar extended by pneumatic pressure from a compressed air cartridge provides the obstruction capability without requiring complex mechanical fixing mechanisms, reducing device complexity and installation time while maintaining effective obstruction.
4Reliability
If the device requires adaptation of wall frames, then the device can be securely installed, but the adaptability to existing structures decreases and installation time increases
Solution Approach 1:
The device is designed with universal applicability to existing wall structures. The telescopic bar can be positioned between standard wall surfaces without requiring modification to the wall frame or structure. The pneumatic jack system adapts to different wall thicknesses and configurations, making the device versatile for various existing structures while maintaining secure installation through the blocking surface engagement mechanism.
