Captive-Latch Access Control for Multi-Unit Authorization Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-unit facilities face challenges in efficiently managing access authorization changes, often requiring manual processes such as lock rekeying and key distribution due to frequent user and authorization changes.
Innovation Solution
A locking mechanism with a hasp and captive latch pin system, integrated with an actuator assembly and processor, allows for electronic control and management of access, including a telescopic hasp design to enhance security and reduce manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual lock rekeying and key distribution processes are used, then access authorization changes can be implemented, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces manual mechanical lock rekeying and key distribution processes with an electronically controlled locking mechanism. The system uses electronic actuators to control hasp movement and electronic authorization credentials (keycards, keycodes, biometrics) instead of physical keys, enabling remote and automated access authorization changes without manual intervention at the lock itself.
Solution Approach 2:
The locking mechanism incorporates local memory devices that store authorization credentials and can independently validate access requests without requiring connection to a remote server. This self-service capability allows the system to autonomously grant or deny access based on locally stored authorization data, eliminating the need for manual rekeying when authorization changes occur.
2Reliability
If traditional locking mechanisms are used, then access control is provided, but the system lacks resistance to tampering and power loss scenarios
Solution Approach 1:
The patent incorporates local memory devices that store authorization credentials locally within the locking mechanism itself, providing a backup authorization source that functions independently of remote server availability or network connectivity. This preliminary cushioning ensures the system can maintain security and authorization capabilities even when external systems are unavailable or compromised.
Solution Approach 2:
The system employs multiple authorization credential types (keycards, keycodes, biometric data) with different security parameters and validation methods. This diversity in authorization parameters provides redundancy and resistance to various tampering scenarios, as compromising one authorization method does not necessarily compromise the entire system.
3Extent of automation
If electronic control systems are implemented, then manual processes are reduced, but the system requires power and becomes vulnerable to power loss
Solution Approach 1:
The patent employs multiple authorization credential types (keycards, keycodes, biometric data) with different security parameters and validation methods. This diversity in authorization parameters provides redundancy and resistance to various tampering scenarios, as compromising one authorization method does not necessarily compromise the entire system.

AI summary
A locking mechanism includes a hasp having a tongue disposed along a first side of the hasp, and a captive latch pin protruding from the hasp disposed away from the tongue. The locking mechanism includes an actuator assembly with a captive latch and an actuator configured to manipulate the captive latch. The captive latch may receive the captive latch pin of the hasp. A body locking mechanism can obstruct access to at least a portion of the hasp and the actuator assembly, wherein the hasp may slidably move when the captive latch pin is not retained by the captive latch, and wherein a retention of the captive latch pin by the captive latch arrests the slidable movement of the hasp.
