Door Safety Device with Remote Actuator and Hidden Locking Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety devices for doors and windows are either limited to actuation from one side, prone to damage from external forces, or vulnerable to tampering and key cloning systems, lacking structural simplicity and cost-effectiveness.
Innovation Solution
A safety device with a movable locking member actuated by an electric motor and worm screw, controlled remotely, which is invisible and tamper-proof, featuring a cylindrical pin that can be rotated to prevent cutting and a containment body with a battery-powered actuator for secure and versatile operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional locks are used that can be actuated from both sides of the door, then the door can be locked from either side, but the lock becomes vulnerable to damage from external forces and tampering
Solution Approach 1:
The locking mechanism is extracted from the traditional visible lock structure and relocated to an invisible position within the door edge. The locking member is contained within a containment body that is integrated into the door, removing the vulnerable external lock components while preserving the ability to lock from both sides.
Solution Approach 2:
An intermediary containment body is introduced between the external environment and the locking mechanism. This containment body protects the locking member from external forces and tampering while still allowing the locking function to operate from either side of the door.
2Ease of operation
If visible locks are used on the door, then the locking function is provided, but the lock becomes visible and susceptible to tampering and break-in systems
Solution Approach 1:
The visible lock components are extracted and removed from the door surface. The locking mechanism is concealed within the door edge, making it invisible to external observers and immune to visual tampering attempts while maintaining the locking function.
Solution Approach 2:
The containment body acts as a protective shell that encloses the locking mechanism. This shell protects the internal components from external access and tampering while allowing the locking function to remain operational.
3Stability of the object's composition
If armoured locks with sliding bars are used, then the door stability on the jamb is improved, but the lock becomes easier to tamper with using forcing systems
Solution Approach 1:
The traditional mechanical forcing systems are replaced with an electric actuator controlled by control means. The locking member is moved by an electric motor rather than manual mechanical force, making it resistant to external forcing attempts while maintaining door stability.
Solution Approach 2:
An intermediary containment body protects the locking mechanism from external access. This containment body prevents forcing systems from directly accessing the locking components while still allowing the locking function to operate through the controlled actuator.
4Device complexity
If simple manual bolts are used, then the device is structurally simple and cost-effective, but the device can only be actuated from the inside of the door
Solution Approach 1:
The locking system is designed with multi-functionality to operate from both sides of the door. The actuator and control means are positioned to allow actuation from either side, providing universal operation while maintaining relative structural simplicity through the integrated containment body design.

AI summary
A safety device for doors, windows, mobile doors and the like, comprising: a locking member(2) movable between a first position in which it obstructs the movement of a respective door (100, 200) or window or mobile door, and a second position in which it does not obstruct the movement of said door (100, 200), window or mobile door; an actuator (3) associated to said locking member (2) to move the element itself in the first and second position; a containment body (4) for said locking member and said actuator, which can be positioned at a zone of passage (A) of the door, window or mobile door; and control means (5) of said actuator, arranged externally to said containment body for activating and/or deactivating the actuator from a remote location.
