Door Lock Drive Bolt Latching for Fast Installation and Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for door assemblies require complex installation and maintenance processes, often necessitating full disassembly and reassembly due to the need for screw-based coupling of drive bolts.
Innovation Solution
A locking device design featuring a coupling means with a receptacle that allows drive bolts to be automatically coupled and uncoupled without screws, utilizing a locking element that can be displaced between coupling and release positions, facilitated by a spring mechanism and actuated via a threaded section for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drive bolts are coupled to the locking device using screws or traditional installation methods, then the connection is secure and reliable, but the installation process becomes time-consuming and complex disassembly is required for maintenance
Solution Approach 1:
The locking device is divided into modular components: a coupling means with receptacles that can independently receive and secure drive bolts without requiring disassembly of the entire locking device. This segmentation allows individual drive bolts to be installed or removed independently, reducing installation time while maintaining secure connections through the receptacle-coupling mechanism.
2Reliability
If the locking device is fully pre-assembled for installation, then the locking function is complete and reliable, but maintenance or replacement of lock components requires removal and partial disassembly of the entire locking device
Solution Approach 1:
The locking device incorporates a coupling means with receptacles that can independently receive and secure drive bolts without requiring disassembly of the entire locking device. This segmentation allows individual drive bolts to be installed or removed independently, reducing installation time while maintaining secure connections through the receptacle-coupling mechanism.
Solution Approach 2:
The coupling means includes a locking element that can be displaced between a coupling position (where it engages the receptacle) and a release position (where it releases the receptacle). This dynamic mechanism allows drive bolts to be easily installed or removed by simply moving the locking element, facilitating maintenance without disassembling the entire locking device while maintaining reliable locking when engaged.
3Reliability
If traditional screw-based coupling is used for drive bolts, then the connection is secure, but the coupling process cannot be easily automated
Solution Approach 1:
The locking device is divided into modular components: a coupling means with receptacles that can independently receive and secure drive bolts without requiring disassembly of the entire locking device. This segmentation allows individual drive bolts to be installed or removed independently, reducing installation time while maintaining secure connections through the receptacle-coupling mechanism.
Solution Approach 2:
The coupling means incorporates a spring element that automatically moves the locking element to the coupling position when a drive bolt is inserted, creating a self-securing mechanism. The spring element provides automatic engagement without requiring manual intervention or complex automation systems, enabling easier automation of the installation process while maintaining secure connections.
