Electronic Safe Lock Local Override for Emergency Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic safe locks in a blocking mode cannot be unlocked from the installation location in case of communication network failures or power supply issues, leading to inconvenience, especially in emergency situations like a fire.
Innovation Solution
A method that allows unlocking of the electronic safe lock in the blocking mode by generating three signals in the local controller, enhancing protection against unauthorized access, and utilizing the lock's wiring without internal modifications, using a local controller to override the remote blocking signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blocking mode of the lock unlocking is activated from a remote controller, then the lock cannot be unlocked in any manner, but this provides enhanced security against unauthorized access
Solution Approach 1:
The blocking mode is made dynamic and reversible through the introduction of a local unblocking code that can be entered via the local controller. The blocking state can be deactivated locally without requiring remote communication, allowing the system to transition between blocked and unlocked states based on user needs.
Solution Approach 2:
A local unblocking code acts as an intermediary mechanism that bridges the remote blocking signal and the local controller. This intermediary allows the local controller to override the remote blocking signal when the unblocking code is entered, enabling selective local access while maintaining remote security.
2Reliability
If the blocking mode remains active due to communication network failures or power supply issues, then the lock cannot be unlocked, but this ensures continuous security protection
Solution Approach 1:
The local controller provides self-service functionality by enabling the user to deactivate the blocking mode and unlock the lock independently without requiring external remote communication or assistance. The local unblocking code can be entered directly on the local controller to override the blocking signal.
Solution Approach 2:
The system prepares for emergency situations by providing a local unblocking mechanism that activates when communication failures or power issues occur. The local controller can independently deactivate the blocking mode using the local unblocking code, ensuring continuous access capability without relying on external systems.
3Reliability
If the lock requires remote control for unblocking, then security is maintained, but the system becomes dependent on external communication infrastructure
Solution Approach 1:
The local controller is given multi-functionality by enabling it to both receive local control signals and override remote blocking signals. The local controller can function independently for normal operations and also serves as the unblocking mechanism when remote control is unavailable, making it a universal control device.
Solution Approach 2:
The local unblocking code serves as an intermediary that allows the local controller to mediate between the remote blocking signal and the lock mechanism. This intermediary capability enables the system to operate independently when needed while maintaining security through the remote blocking function.

AI summary
A method of controlling an electronic safe lock (1) with an electronic unit (2) of the lock (1) and with an electronic remote control unit (3) wherein the blocking mode of the lock (1) unlocking is activable/deactivable from the remote controller (4), when an blocking signal (21) / remote unblocking signal (22) is generated in the remote controller (4) and this signal is transmitted via the electronic remote control unit (3) to the electronic unit (2) of the lock (1), where it blocks/unblocks the unlocking of the lock (1). Wherein in the blocking mode of the lock (1) unlocking, the lock (1) can also be unlocked from the local controller (5) by generating a local unblocking signal (23) and transmitting it to the electronic unit (2) of the lock (1), where it cancels the effect of the blocking signal (21). Subsequently, the internal unlocking signal is activated.
