Wireless SST Safe Lock Drive Eliminates Drilled Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ATM safes are vulnerable to theft due to the need for expensive locks and drilling holes, which increases manufacturing costs and complicates security decisions for distributors and operators.
Innovation Solution
A wireless-secured safe with a lock drive that operates inside the safe, receives cryptographically authenticated codes for locking or unlocking, eliminating the need for external handles and holes, using a secure microcontroller and Bluetooth communication for secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locks with handles and spindles are installed in safe doors, then security is improved, but manufacturing cost increases and drilling holes create vulnerability points
Solution Approach 1:
The patent extracts the lock mechanism from the traditional external installation method and relocates it entirely inside the safe. The lock drive, motor, and control electronics are housed within the safe interior, eliminating the need for external handles, spindles, and drilled holes in the safe door. This extraction resolves the contradiction by maintaining security functionality while eliminating manufacturing complexity and vulnerability points.
Solution Approach 2:
The patent replaces the mechanical lock system with an electromagnetic motor-driven lock mechanism. Instead of traditional mechanical spindles and handles that require drilling holes, an electric motor (150) drives a lock drive (103) that engages with the safe door from the inside. This substitution eliminates the need for external mechanical components and drilled holes, reducing manufacturing cost while maintaining security.
2Reliability
If expensive locks with handles and spindles are integrated into safe doors, then security is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple components into a single integrated lock mechanism housed inside the safe. The motor (150), lock drive (103), control electronics, and power supply are combined into one compact assembly that replaces the complex external arrangement of handles, spindles, and separate lock mechanisms. This merging reduces device complexity while maintaining security functionality.
Solution Approach 2:
The internal lock mechanism serves multiple functions: it can lock the safe door, unlock it with authorized codes, and is controlled entirely from within the safe. The single integrated mechanism replaces multiple external components (handle, spindle, lock body, keyhole), reducing overall device complexity while providing comprehensive security functionality.
3Reliability
If drilling holes into safe doors for lock installation is performed, then lock integration is achieved, but vulnerability points are created for thieves
Solution Approach 1:
The patent extracts the entire lock mechanism from the safe door exterior and relocates it inside the safe interior. By removing the lock components from the door surface, no holes need to be drilled, eliminating the vulnerability points that thieves could exploit. The lock mechanism is accessed and controlled entirely from within the safe through wireless communication.
Solution Approach 2:
The patent introduces wireless communication as an intermediary between the control system and the lock mechanism. Instead of requiring physical connections through drilled holes, the lock is controlled wirelessly via Bluetooth or other wireless protocols. This intermediary eliminates the need for physical penetrations in the safe door, removing vulnerability points while maintaining lock integration.

AI summary
A Self-Service Terminal (SST) safe that includes a lock drive adapted and configured to i) operate inside the SST safe, ii) receive a wireless code sent from outside the SST safe, and iii) determine whether to lock or unlock the SST safe from inside the SST safe in response to the wireless code, and wherein the wireless code is cryptographically secured and authenticated prior to any unlock or lock operation.
