Embedded Door Lock Assembly for Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency exit door locks are vulnerable to theft and damage due to their external placement, which makes them susceptible to long-term misuse.
Innovation Solution
A door lock device with a lock assembly comprising a driving member, an acting member, and a main lock member, where the driving member drives the acting member to swing, displacing the active member and synchronously the main lock member, allowing the lock assembly to be buried within the door frame, thereby protecting it from damage and theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lock is arranged outside the door with its lock head extending or retracting at a door position, then the lock is easily accessible for operation, but it is easily stolen or damaged during long-term use
Solution Approach 1:
The patent extracts the vulnerable lock head from the external door surface and relocates it to the interior side of the door. The lock body is embedded within the door structure, with only the operating handle exposed externally. This extraction of the lock mechanism from its traditional external position eliminates its exposure to theft and damage while preserving operational accessibility through the interior-mounted components.
Solution Approach 2:
The lock assembly is nested within the door structure, with the lock body housed inside the door thickness rather than protruding externally. The operating mechanism is integrated into the door's internal volume, creating a nested configuration where the functional lock components are contained within the door itself. This nesting protects the lock while maintaining operational capability through the door's interior surface.
2Reliability
If the lock assembly is buried in the door frame, then it is protected from being damaged or stolen, but the structure becomes more complex
Solution Approach 1:
The patent merges the lock assembly with the door frame structure by embedding the lock body directly into the door's internal volume. The lock housing is integrated with the door's structural elements, and the operating mechanism is combined with the door's existing framework. This merging eliminates the need for separate external lock housings and mounting structures, reducing overall structural complexity while achieving embedded protection.
Solution Approach 2:
The door structure serves multiple functions: it provides the primary barrier function, houses the lock assembly, and integrates the operating mechanism. The door frame acts as both a structural support and a mounting structure for the lock components. This multi-functionality reduces the need for additional specialized components, thereby reducing structural complexity despite the embedded configuration.

AI summary
A door lock device is provided and includes a lock assembly and an operation assembly interlocked with the lock assembly so as to bury the lock assembly in a door frame, thereby protecting the lock assembly from being damaged or stolen.
