Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing property monitoring systems lack an effective mechanism to detect attempted entries and respond appropriately, especially in enhancing security for both occupied and unoccupied properties.
Innovation Solution
The implementation of an attempted entry detection system using smart locks equipped with sensors such as lever position sensors, pressure sensors, and vibration sensors, which can detect and respond to attempts to enter a locked door or window by alerting residents, activating surveillance cameras, and simulating occupancy through lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional monitoring systems are used without attempted entry detection, then the system structure remains simple, but security effectiveness is insufficient
Solution Approach 1:
The patent combines multiple sensor types (lever position sensors, pressure sensors, vibration sensors) into an integrated smart lock system that detects attempted entries through multiple physical parameters simultaneously, resolving the contradiction by merging detection capabilities while maintaining unified system operation
Solution Approach 2:
The smart lock system performs multiple functions: it serves as a conventional lock, a detection device with multiple sensor types, a notification system, and an interface for monitoring systems, thereby improving security effectiveness while the multi-functionality justifies the increased complexity through consolidated design
2Measurement precision
If multiple sensor types are integrated into smart locks for comprehensive detection, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The patent segments the detection system into distinct sensor modules (lever position sensors for rotational detection, pressure sensors for force detection, vibration sensors for shaking detection), each optimized for specific detection tasks, thereby improving overall detection accuracy while managing complexity through modular architecture
Solution Approach 2:
Different sensor types are strategically positioned at specific locations within the smart lock mechanism to detect local physical changes (lever rotation at the handle, pressure at the bolt interface, vibration at the deadbolt), enhancing detection precision for each specific attempted entry method while keeping each sensor's function specialized and manageable
3Reliability
If monitoring systems activate multiple response actions upon detecting attempted entry, then security response effectiveness improves, but system complexity increases
Solution Approach 1:
The system pre-configures multiple response actions (sending notifications to mobile devices, activating surveillance cameras, triggering alarms, notifying monitoring services) that are automatically executed upon detection, improving response effectiveness while the pre-programmed nature of these actions manages control complexity through established protocols

Function Achieved in This Case
This solution provides an additional layer of security by alerting residents to attempted entries, deterring unauthorized access, and enhancing the security of both occupied and unoccupied properties by simulating occupancy and activating surveillance.
Implementation Method 1
vibration sensors may be positioned on or near a deadbolt, in order to detect vibration of the deadbolt caused by a person shaking the locked door
Implementation Method 2
pressure sensors that can detect pressure of a person attempting to rotate a locked door lever or doorknob
Implementation Method 3
lever position sensors that can detect rotation of a door lever or doorknob
Data Source
AI summary
Methods, systems, and apparatus for attempted entry detection are disclosed. A method for monitoring a property includes receiving, from a smart lock of a door located at a property monitored by a monitoring system, smart lock data that reflects a condition of the smart lock; receiving, from a sensor of the monitoring system, sensor data; analyzing the smart lock data and the sensor data; based on analyzing the smart lock data and the sensor data, determining that an attempted door entry is occurring; and in response to determining that an attempted door entry is occurring, performing a monitoring system action. Determining that an attempted door entry is occurring can include determining, based on the sensor data, that a person is located near the smart lock; and determining, based on analyzing the smart lock data, that the smart lock data satisfies criteria for an attempted door entry.
