Movable Bolt Closure System for Door Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bolt lock systems face challenges in maintaining high security with minimal installation and maintenance efforts, particularly due to inaccuracies in door leaf positioning relative to the door frame, which can lead to reduced security over time as the door 'sets' due to gravity, requiring frequent adjustments and inspections.
Innovation Solution
A bolt closure system where the locking element is movably mounted along a first axis parallel to the frame part axis, allowing it to compensate for deviations and apply force to ensure the locking hook engages fully, with a detection device to monitor the locking status and a prestressing device to maintain contact without requiring complex initial alignment or regular maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking element is fixed in position, then the assembly structure is simple, but assembly inaccuracies and door settling cause reduced security over time
Solution Approach 1:
The bolt element is made movable along the first axis parallel to the frame part axis, allowing it to dynamically adjust its position to compensate for door settling and assembly inaccuracies. This dynamic capability ensures continuous optimal engagement between the locking hook and bolt element, maintaining high security without requiring complex adjustment mechanisms.
2Reliability
If the locking element is made movable to compensate for position deviations, then security is maintained over time, but the device complexity increases
Solution Approach 1:
The bolt element is designed with movable mounting along the first axis, enabling automatic position compensation for door settling and assembly variations. This single-degree-of-freedom movement provides continuous optimal engagement without requiring complex multi-axis adjustment mechanisms or frequent manual intervention.
3Reliability
If high assembly precision is required for optimal locking engagement, then security is maximized, but assembly effort and cost increase
Solution Approach 1:
The movable bolt element compensates for assembly inaccuracies automatically during operation, eliminating the need for high-precision assembly procedures. The system adapts to position deviations through the bolt element's movement capability, significantly reducing assembly skill requirements and manufacturing costs while maintaining optimal locking engagement.
