Cylinder Lock Segmented Scanning Unit for Break-in Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock cylinders with rotatable and lockable cylinder cores face challenges in precise adjustment to door thickness, leading to security vulnerabilities due to protrusion and increased logistical and production efforts from accommodating safety tumblers, which compromise security and require multiple stock versions.
Innovation Solution
A modular locking device integrated in a separate scanning unit that detects the presence or absence of the lock cylinder module, engaging a blocking mechanism in a core extension rather than the cylinder core, with a predetermined breaking point in the axle to prevent unauthorized access without altering the housing or core pin arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety tumbler is integrated into the cylinder housing, then security against break-in attempts is improved, but device complexity and production effort increase due to multiple housing versions
Solution Approach 1:
The locking device is divided into separate functional components: the scanning unit with tracer pin is separated from the cylinder housing, and the locking bolt is integrated into the cylinder core. This segmentation allows the safety tumbler function to be added without redesigning the entire housing structure, eliminating the need for multiple housing versions.
Solution Approach 2:
The scanning function is extracted from the housing and placed in a separate scanning unit that can be independently attached to the cylinder. This extraction allows the safety feature to be added modularly without altering the base housing design, reducing production complexity.
2Reliability
If the cylinder housing is modified to accommodate the safety tumbler, then security is improved, but the housing strength is reduced due to additional bores and recesses
Solution Approach 1:
By separating the scanning unit from the housing, the invention avoids creating additional bores and recesses in the housing structure. The scanning unit operates independently, eliminating the structural weakening that would result from housing modifications.
3Adaptability or versatility
If multiple versions of the cylinder housing are produced to accommodate different safety tumbler configurations, then adaptability is improved, but manufacturing complexity and inventory requirements increase
Solution Approach 1:
The scanning unit is designed as a universal module that can be attached to standard cylinder housings without modification. The tracer pin scans for the locking bolt in the cylinder core, providing a universal safety tumbler function that works with existing housing designs, eliminating the need for multiple specialized housing versions.
4Ease of manufacture
If the locking device is integrated into the existing cylinder core structure, then ease of manufacture is improved, but the ability to block unauthorized access is reduced
Solution Approach 1:
The tracer pin acts as an intermediary element that connects the scanning unit to the locking bolt in the cylinder core. It detects the presence or absence of the locking bolt and triggers the blocking mechanism, providing an effective security function while maintaining compatibility with existing cylinder core structures.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for easy retrofitting of existing locks with enhanced security, reducing production complexity and logistical burdens while maintaining security against break-in attempts by ensuring the axle breaks instead of the housing, thus preventing unauthorized access.

AI summary
The cylinder (1) has a cylinder core (3) rotatable in a lock cylinder module (27), and a safety bolt (12) for blocking a core extension (11) formed at the core during interruption of the cylinder module. The safety bolt is arranged at a scanner unit (34) in the cylinder module, and has a scanning pin (10) for scanning position of the cylinder module and a locking bolt (20) for blocking the core extension. The cylinder module has a housing part (2b), and the scanner unit has a housing extension (7) that accommodates the safety bolt, where the core extension has a coupling extension (13).
