Two-Part Lock Bolt Assembly Against Unauthorized Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks are vulnerable to unauthorized manipulation and lack versatility in control options, leading to potential security breaches.
Innovation Solution
The lock is designed with a two-part bolt assembly where the connecting rod is connected to a lower part of the locking mechanism, held by a button, allowing independent control of the bolt and slide, and features a clearance between parts to decouple the gearbox, preventing unauthorized unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single bolt assembly is used, then the lock structure is simple, but the control options and security levels are limited
Solution Approach 1:
The bolt assembly is divided into two independent segments: a first segment connected to the drive rod for primary locking control, and a second segment for additional locking mechanisms. This segmentation allows each segment to be controlled independently by the locking cylinder, providing multiple control options and security levels while maintaining a manageable structural complexity through modular design
2Reliability
If the locking mechanism is integrated as a single unit, then manufacturing is easier, but wear and malfunction risk increase during operation
Solution Approach 1:
The locking mechanism is segmented into a first bolt segment and a second bolt segment that can operate independently. The drive rod connects to the first segment while the second segment has its own control pathway through the locking cylinder. This segmentation reduces wear on individual components by distributing operational stress and prevents total malfunction if one segment experiences issues, while the modular structure facilitates easier manufacturing and assembly
3Ease of operation
If the bolt can be driven freely in both directions, then operation is easier, but unauthorized unlocking becomes possible
Solution Approach 1:
The locking mechanism employs dynamic control through the locking cylinder that can selectively engage either the first segment or the second segment based on the direction and extent of cylinder rotation. The system transitions between different operational states: normal locking through the first segment, enhanced security through the second segment, and controlled unlocking. This dynamic behavior allows easy legitimate operation while preventing unauthorized unlocking attempts

AI summary
A lock with a bolt mechanism (6) has two segments (10, 11) driven by a locking cylinder, one of the segments (10) driving the bolt mechanism (6) to lock and the other of the segments (11) driving it to unlock. Furthermore, a locking device (32) is actuated, which blocks the bolt mechanism (6) in the locked position. This provides the lock with a high level of protection against manipulation.
