Door Lock Anti-Drill Disc Rotation Sensing for Early Drilling Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locks fail to detect break-in attempts by drilling the cylinder rotor in a timely manner, leading to significant damage before detection.
Innovation Solution
A door lock system equipped with an anti-drill pad and a break-in detection device that measures the rotation of the anti-drill pad to quickly identify drilling attempts, triggering alarms or countermeasures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive tracks are used to detect drilling attempts, then detection reliability is improved, but detection timing is delayed until the cylinder is already seriously damaged
Solution Approach 1:
The patent applies preliminary action by placing the break-in detection device at the anti-drill pad surface, which is the first point of contact during a drilling attempt. This allows detection to occur before the drill bit penetrates deep into the cylinder rotor, enabling early intervention while maintaining high reliability through the conductive track damage detection mechanism.
2Strength
If the anti-drill pad is made robust to prevent drilling, then protection effectiveness is improved, but the lock becomes more vulnerable to other attack methods
Solution Approach 1:
The patent implements feedback by continuously monitoring the integrity of the anti-drill pad through the break-in detection device. When drilling is detected via conductive track damage, the system immediately triggers an alarm and can activate countermeasures. This feedback loop allows the system to respond dynamically to threats, compensating for the static nature of the physical anti-drill pad and addressing vulnerabilities to other attack methods through active surveillance and response capabilities.

AI summary
The lock includes a break-in attempt detection device comprising: - a unit (150) for measuring the rotation of an anti-drilling disc located in front of the entrance of a key channel, and - a break-in attempt detection module (92) configured to: - acquire the measurements of the measuring unit (150) and deduce the rotation speed of the anti-drilling disc, - compare the rotation speed of the anti-drilling disc to a predetermined maximum threshold, and - automatically trigger the report of a break-in attempt as soon as the measured rotation speed exceeds this predetermined maximum threshold and, otherwise, not trigger this report of a break-in attempt.
