Multi-Point Door Lock Assembly with Wedge-Shaped Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional door entry systems have a single or dual point of locking connection between the door panel and frame, making them susceptible to forced opening, and often fail to effectively seal against environmental elements like noise, weather, and insects due to inadequate sealing mechanisms.
Innovation Solution
A door lock assembly with a movable locking element that locks and seals the door to the frame, featuring a rail-style, wedge-shaped locking mechanism and a resilient member to enhance sealing and reduce noise during operation, along with a system for user registration and access management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional latch mechanisms with single or dual point locking connections are used, then the door can be easily locked, but the door is susceptible to forced opening and inadequate sealing
Solution Approach 1:
The locking system is divided into multiple locking points distributed along the door edge, transforming a single-point latch into a multi-point locking system. This segmentation increases security by requiring simultaneous failure of multiple locking points for forced entry, while maintaining simple operation through a single actuator that engages all points.
Solution Approach 2:
The locking mechanism transitions from a single-point engagement to a distributed linear array of locking points along the door edge. This dimensional expansion from point to line provides both enhanced security through multiple engagement points and improved sealing along the entire door-perimeter interface.
2Object-affected harmful factors
If traditional weather stripping is used between door panel and frame, then sealing is attempted, but the seal becomes disjoined and ineffective
Solution Approach 1:
The sealing function is merged with the locking mechanism itself. The locking elements serve dual purposes: securing the door at multiple points and maintaining continuous contact with the frame to prevent environmental element penetration. This eliminates the need for separate weather stripping that can become disjoined.
Solution Approach 2:
The locking elements are designed to perform multiple functions simultaneously: mechanical locking to prevent door opening and sealing to block environmental elements. This multi-functionality ensures that the same structural components providing security also maintain seal integrity, preventing noise, weather, and insect penetration.
3Reliability
If multiple locking points are implemented, then forced entry resistance improves, but device complexity increases
Solution Approach 1:
The locking system is designed to automatically engage multiple locking points through a single actuation action. The mechanism self-distributes the locking force along the door edge without requiring manual intervention at each point, reducing operational complexity while maintaining multiple secure engagement points.
Solution Approach 2:
The patent replaces complex multi-component mechanical locking systems with a streamlined mechanism that uses a single actuator to engage multiple locking points. This substitution reduces the number of moving parts and mechanical components while achieving the same or improved security performance.
