Solution Overview
Problem
There is a need for an improved attachment system for sensors to determine the condition of door or window locks or latches without manual intervention, allowing remote monitoring and tamper detection.
Innovation Solution
A module with first and second sensor units and a magnet that moves along a magnet path, detecting changes in magnetic field polarity to determine the lock or latch condition, and an attachment system using a securing member to secure the module to the frame, with tamper detection capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a sensor is attached to the door or window frame to determine lock or latch condition, then remote monitoring capability is improved, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical sensing mechanisms with a magnetic field-based detection system. A magnet is attached to the lock or latch mechanism, and sensor units in the module detect the magnet's position and polarity changes to determine lock/latch status. This substitution of mechanical sensing with magnetic sensing simplifies the overall system while enabling remote monitoring capability.
2Measurement precision
If multiple sensor units are used to detect magnetic field polarity changes, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor units within a single module housing, integrating them into one unified component that attaches to the frame. This merging approach allows the system to detect magnetic field polarity changes from multiple angles or positions simultaneously, improving measurement precision for determining lock/latch status while presenting a single integrated unit rather than separate components.
3Ease of operation
If a securing member with resiliently biased clip is used to attach the module, then ease of installation is improved, but reliability of attachment may worsen
Solution Approach 1:
The patent employs a resiliently biased clip in the securing member that provides dynamic attachment. The clip can flex and adjust to accommodate variations in frame dimensions and positioning tolerances, making installation easier by allowing the module to be secured without precise alignment. The resilient nature maintains reliable attachment through continuous contact force while accommodating dynamic conditions in the installation environment.
