Gate Lock Shell and Base Design for Emergency Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrically operated locking devices for gates lack emergency opening capabilities during power failures and require cumbersome maintenance processes, especially for battery replacement and internal component access.
Innovation Solution
A locking device with a movable base part and a shell mechanism that allows mechanical emergency unlocking, secure battery access, and maintenance without removing the base part, featuring a mechanical locking mechanism to switch between applied and removed positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base part is fixed to the frame for secure locking, then the locking reliability is improved, but the ease of maintenance deteriorates because battery access and processor adjustments require removing the entire base part
Solution Approach 1:
The base part is segmented into two functional sections: a fixed portion attached to the frame for maintaining locking reliability, and a movable portion that can be accessed independently for battery replacement and processor adjustments. This segmentation allows maintenance operations without compromising the secure attachment of the locking mechanism.
Solution Approach 2:
The battery compartment and processor access points are extracted as separate accessible components from the main base part structure. This allows maintenance personnel to access and service these components independently without removing the entire base part from the frame, thereby improving ease of repair while maintaining locking reliability.
2Reliability
If the locking device requires physical removal for emergency access during power failure, then the security is improved, but the emergency response time deteriorates and requires specialized training
Solution Approach 1:
A manual override mechanism is pre-configured within the locking device that authorized personnel can access during power failures. This preliminary action enables emergency opening without requiring removal of the base part or specialized training, reducing emergency response time while maintaining normal security conditions through the electrically controlled locking mechanism.
3Ease of repair
If the base part is made accessible for maintenance, then the ease of repair is improved, but the security against unauthorized access deteriorates
Solution Approach 1:
Different security levels are applied to different parts of the base part. The battery compartment and processor access points are designed with localized access mechanisms that can be opened by authorized personnel for maintenance, while the main locking mechanism remains securely attached and protected. This local quality differentiation allows easy repair of maintenance components without compromising the security of the critical locking function.

AI summary
An electrically operable locking device configured for the locking of a gate wing (402), by electrically extending a drop bolt from a base part (300), the locking device comprising: • a frame arranged for being fixed to the gate wing, • the base part supported on the frame, wherein the base part is arranged mechanically movable with respect to the frame in a length direction between an extended position, and a retracted position whereby if the drop bolt (302) is extended from the base part, the drop bolt is disengaged from the fixed bolt reception element and the gate wing is released, and • a shell (100) arranged mechanically movable in the length direction with respect to the base part between an applied position and a removed position, wherein the locking device further comprises a mechanical locking mechanism fixed in the shell and provided for locking the shell to the frame, and wherein the shell and the base part are releasably interconnected by means of a releasable connection member.
