Automated Door Lock Magnet Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated door locks lack a discreet and reliable method to detect when a door is fully closed, which is essential for automatic locking and notification systems, often relying on external sensors that are visible and not always accurate.
Innovation Solution
Incorporating a magnet and reed switch sensor system within the lock plate assembly, where a magnet on one plate interacts with a sensor on another, allowing the control logic to determine the door's closure state without visible external sensors, enabling automatic locking and notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external sensors are used to detect door closure, then detection function is provided, but the sensor becomes visible and less discreet
Solution Approach 1:
The sensor is merged with the lock plate assembly, combining the detection function with the existing structural component. This integration allows the sensor to be positioned internally within the lock mechanism rather than externally, maintaining aesthetic appearance while preserving detection functionality.
Solution Approach 2:
The sensor is nested within the lock plate assembly structure, placing the detection component inside the existing lock housing. This nesting approach hides the sensor from external view while maintaining its operational effectiveness for detecting door closure state.
2Shape
If a magnet and sensor system is integrated within the lock plate assembly, then the sensor becomes hidden and discreet, but the device complexity increases
Solution Approach 1:
The lock plate assembly is designed to serve multiple functions: it provides structural support for the lock mechanism, houses the sensor component, and contains the magnet for detection. This multi-functionality reduces the need for separate components and minimizes overall device complexity despite adding detection capabilities.
Solution Approach 2:
The magnet and sensor system within the lock plate assembly operates autonomously to detect door closure without requiring external power sources or additional control mechanisms. The existing lock plate structure serves as the mounting platform, eliminating the need for separate mounting hardware and reducing assembly complexity.

AI summary
An automated door lock includes a bolt and bolt housing. A lock interior part is attachable to an inside portion of a door. The lock interior part includes control logic that controls operation of automated door lock including movement of the bolt into and out of the bolt housing. A first lock plate is attachable to a door frame. The first lock plate includes a magnet. The second lock plate is attachable to a door. The second lock plate includes a sensor electrically connected to the control logic. The sensor detects magnetic field strength. The magnet is located on the first lock plate and the sensor is located on the second plate so that when the door is closed, the sensor and the magnet are aligned to maximize strength of the magnetic field detected by the sensor.
