Lock Encapsulated Modular Unit Assembly Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks are vulnerable to manipulation through insertion of objects into the lock housing and can be compromised by external blows or kicks, with separate components making assembly laborious and time-consuming.
Innovation Solution
An integrated encapsulated modular unit housing the second follower, blocking element, and latching member within the lock housing, which is arranged on the rear side and features a robust modular housing, making manipulation more difficult and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the second follower, blocking element and latching member are arranged as separate parts in the lock housing, then the lock can be assembled with individual components, but manipulation of the lock by insertion of objects into the lock housing becomes possible and assembly becomes laborious and time-consuming
Solution Approach 1:
The second follower, blocking element, and latching member are merged into a single integrated modular unit that is fitted as one piece into the lock housing. This combination prevents manipulation by insertion of objects and simplifies assembly, directly resolving the technical contradiction between security and assembly ease.
2Ease of operation
If the blocking element and latching means are accessible through the lock housing, then they can be operated independently, but manipulation by thin objects such as feelers or steel wires becomes possible
Solution Approach 1:
The blocking element and latching member are nested within the encapsulated modular unit, which is itself fitted into the lock housing. This nested arrangement protects the operational components from manipulation by thin objects while maintaining their operational functionality through the integrated unit.
3Ease of repair
If the lock components are arranged separately in the lock housing, then individual replacement and repair is possible, but the fitting process becomes laborious and time-consuming
Solution Approach 1:
The lock is segmented into modular units, with the second follower, blocking element, and latching member forming one replaceable module. This segmentation allows the entire module to be quickly replaced as a single unit, reducing assembly time while maintaining ease of repair through modular replacement.

AI summary
Lock comprising a lock housing (10) in which are accommodated: a first follower (13), at least one coupling member (16, 17), which by means of the first follower is movable between a locked and an unlocked position for actuation of a lock bolt, a second follower (40), and a blocking element (50), which by means of the second follower is movable between a blocking position, in which the coupling member is blocked in its locked position, and a release position, in which the coupling member is movable at least from the locked into the unlocked position. A latching member (60) is arranged to allow latching of the blocking element in its blocking position. The second follower, the blocking element and the latching element are accommodated in an encapsulated modular unit (30) which is fitted as an integrated unit in the lock housing.
