Multi-Point Locking Device Independent Secondary Lock Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices with main and secondary locks are vulnerable to operational failures due to warping or unauthorized manipulation, as they are coupled together, leading to compromised safety and reliability.
Innovation Solution
A locking device design where the main lock and secondary locks are coupled via separate drive rods with connecting pieces, allowing independent operation and distribution along the door or window height, ensuring secure locking even if one secondary lock is damaged or manipulated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main lock and secondary locks are coupled together by connecting rods, then the locking device can be operated together with simple structure, but if one lock blocks during closing due to warping or manipulation, the other locks cannot be closed completely, compromising safety and reliability
Solution Approach 1:
The locking device is segmented into independent locking units (main lock and secondary locks) that are spatially separated and can operate independently. Each lock has its own locking element and drive mechanism, allowing one lock to function even if another is blocked or manipulated, thereby improving reliability without requiring a completely complex interconnected structure.
2Reliability
If the main lock and secondary locks are spatially separated and can be operated independently, then security is maintained even if one lock is compromised, but the structural complexity increases with separate drive rods and connecting pieces
Solution Approach 1:
The locking system is divided into independent locking units with separate drive mechanisms. Each secondary lock has its own drive rod that can be actuated independently from the main lock, allowing spatial separation and independent operation. This segmentation ensures that compromise of one lock does not affect the others, maintaining security reliability.
Solution Approach 2:
Connecting pieces serve as intermediaries that allow the drive rods to pass through the forend structure. These connecting pieces with passages enable the drive mechanisms to transmit force through the forend without direct connection between locks, facilitating independent operation while maintaining a relatively simple overall structure.
3Reliability
If multiple secondary locks with different locking elements are used, then unauthorized manipulation is made more difficult and security is enhanced, but the device complexity and number of components increase
Solution Approach 1:
Different locking elements are assigned to different secondary locks based on their specific functions and positions. The first secondary lock has a locking element of the first type (e.g., hook-shaped) while the second secondary lock has a locking element of the second type (e.g., ball-shaped). This local differentiation enhances security against various manipulation methods while keeping each individual locking element relatively simple.
Solution Approach 2:
The locking device employs a composite approach by combining different types of locking elements (hook-shaped, ball-shaped, or other variants) within the same system. This diversity in locking element types creates multiple barriers against unauthorized manipulation, enhancing overall security reliability without requiring each individual element to be overly complex.
