Lifting-Member Door Locking Mechanism for Forced-Entry Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional deadbolt locks are easily defeated and provide insufficient resistance against forced entry, as they apply force across a small area and can be overcome with minimal effort.
Innovation Solution
A locking apparatus with a lifting member that translates force across a larger area, incorporating a strap to flex and transfer energy into the mounting surface, and a control circuit to automate operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional deadbolt lock is used, then the locking mechanism is simple and easy to install, but it provides insufficient resistance against forced entry and can be easily defeated
Solution Approach 1:
The locking apparatus is divided into distinct functional components: a lifting member for engagement, a strap for force distribution, a actuator for operation, and a control circuit for automation. This segmentation allows each component to specialize in a specific function, improving overall strength while keeping individual components relatively simple and manageable.
Solution Approach 2:
The locking mechanism transitions from a traditional linear deadbolt to a vertically movable lifting member that engages with a strike plate. This dimensional change from horizontal to vertical movement allows the lock to distribute force across a larger area of the door and frame, significantly increasing resistance against forced entry while maintaining operational simplicity.
2Force
If a deadbolt is mounted within the door, then the installation is straightforward, but it applies force across a small area and can be overcome with minimal effort
Solution Approach 1:
The strap component is designed with varying local properties - it is flexible in some areas to allow movement and rigid in others to transfer force effectively. This local quality variation enables the strap to adapt to the door and frame geometry while distributing force across a larger contact area, increasing resistive force without requiring complex installation.
Solution Approach 2:
The locking apparatus uses composite construction combining metal components for strength, flexible materials for the strap, and durable materials for the lifting member and strike plate. This composite approach allows the system to apply force across a larger area while maintaining high resistive force capability, overcoming the limitation of traditional single-material deadbolts.
3Reliability
If traditional lock mechanisms are used, then the device is simple to operate, but it provides insufficient security against modern entry methods like lock bumping
Solution Approach 1:
The control circuit automatically detects attempted entry methods (such as lock bumping) and responds by engaging or maintaining the locked state without requiring user intervention. The system monitors strap tension, lifting member position, and other parameters to autonomously maintain security, providing reliable protection while keeping operation simple through automated response to threats.
Solution Approach 2:
The locking apparatus incorporates feedback mechanisms through sensors that monitor the state of the lifting member, strap tension, and actuator position. This feedback loop allows the control circuit to detect forced entry attempts and adjust the locking state accordingly, maintaining high reliability against modern entry methods while requiring minimal user input for operation.
