Door Lock Plug With Dynamic Deadlock For Tamper Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking systems are susceptible to tampering, which compromises their security by allowing unauthorized access or exit from secured rooms.
Innovation Solution
A lock system featuring a first housing, a plug, and a deadlock system or actuation system that moves between positions to inhibit or allow movement of the plug, ensuring secure closure and preventing tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional door locking system is used, then the door can be opened by authorized individuals, but the system is susceptible to tampering and forced entry
Solution Approach 1:
The plug is positioned to protrude from the housing and block the opening before any tampering attempt can occur. This preliminary blocking action prevents unauthorized access by stopping the tamperer's tool or force from reaching the locking mechanism components, thereby countering potential harmful actions in advance
Solution Approach 2:
The plug serves as an intermediary element between the housing and the external environment. It mediates the interaction by physically blocking the opening and preventing direct contact between tampering tools and the locking mechanism, thus protecting the system from harmful external factors
2Reliability
If the plug is always in the plugged position to prevent tampering, then security is improved, but the door cannot be opened by authorized individuals
Solution Approach 1:
The locking system transitions from a static to a dynamic state through the actuation mechanism. The plug dynamically changes position between protruding (secured) and retracted (accessible) states based on authorization, allowing the system to adapt its security level while maintaining both security and operational accessibility
Solution Approach 2:
The actuation mechanism is pre-configured to automatically move the plug between positions based on authorized input. This preliminary programming ensures that when authorization is provided, the plug automatically retracts to allow door opening, eliminating the need for manual intervention and maintaining ease of operation
3Object-affected harmful factors
If the plug protrudes from the housing to block the opening, then tampering is prevented, but the device complexity increases
Solution Approach 1:
The plug, actuation mechanism, and locking mechanism are merged into a single integrated assembly. This combination reduces device complexity by eliminating separate components and their associated mounting structures, while still achieving the dual function of tampering prevention and authorized access

AI summary
A lock system includes a first housing, a plug, and a deadlock system. The first housing including a first side defining an opening. The plug is disposed within the first housing and is configured to move within the opening between an open position and a plugged position. The deadlock system is disposed within the first side of the first housing and coupled to the plug. The deadlock system is configured to move between a first position and a second position. The deadlock system (i) inhibits movement of the plug in the first position and (ii) allows movement of the plug in the second position.
