Anti-removal Elastic Element for Signalling Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light and/or acoustic signalling apparatuses in anti-theft systems are vulnerable to tampering and removal during break-in attempts, as they can be easily dislodged from walls using tools like crowbars and subsequently neutralized by short-circuiting.
Innovation Solution
Incorporation of an anchoring anti-removal elastic element that deforms to exert a return force towards the wall when the apparatus is attempted to be removed, combined with anti-tampering devices that trigger an alarm signal upon forced opening or detachment, enhancing the apparatus's resistance to removal and tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fixing means (screws) are used to mount the signalling apparatus to the wall, then the apparatus can be easily installed and positioned, but the apparatus can be easily removed and tampered with during break-in attempts
Solution Approach 1:
The patent employs dynamic elements including an elastic anchoring element that deforms under load to provide progressive resistance, and a movable rod that transitions from a retracted to extended position to engage with the wall structure. This dynamic behavior allows the system to adapt to removal attempts by increasing resistance as force is applied, rather than relying solely on static mechanical fastening
Solution Approach 2:
The patent implements preliminary anti-action by positioning the elastic anchoring element and movable rod in advance to create obstacles against removal. The elastic element is pre-tensioned and the rod is positioned to engage with the wall before any removal attempt occurs, so that when a break-in attempt happens, the resistance is already in place and activates immediately without requiring additional actions
2Reliability
If the apparatus is firmly anchored to prevent removal, then tampering resistance improves, but the complexity of the fixing mechanism increases
Solution Approach 1:
The patent introduces an elastic anchoring element as an intermediary between the apparatus and the wall structure. This elastic element serves as a mediator that provides both mechanical connection and resistance to removal attempts through its deformation characteristics, simplifying the overall system by replacing complex multi-component anchoring mechanisms with a single elastic element that performs multiple functions
Solution Approach 2:
The patent utilizes a flexible elastic anchoring element that can deform under load while maintaining its connection function. This flexible element absorbs and distributes forces during removal attempts, providing tampering resistance through its elastic properties rather than through rigid mechanical interlocking, thereby reducing the complexity of the anchoring mechanism
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
The solution significantly hinders the removal of the signalling apparatus from its wall mounting, reduces the effectiveness of tampering attempts, and ensures continued operation by triggering an alarm signal upon unauthorized access, thereby enhancing the security and reliability of the anti-theft alarm system.
Implementation Method 1
an anchoring anti-removal elastic element which is arranged to deform and to exert on the box-shaped casing an elastic return force towards the plane support surface when the apparatus is assembled and mounted on the plane support surface and when the box-shaped casing is moved away from the plane support surface
