Strike Plate Bolt Sensing via Integrated Sensor Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door security systems cannot accurately determine if a door is fully latched, as they fail to provide exact location information about the bolt within the strike box, and their installation is time-consuming and aesthetically unpleasing.
Innovation Solution
A sensor assembly is integrated within the strike box of the strike assembly, utilizing various types of sensors such as optical, mechanical, continuity, inductive, and ultrasonic sensors to detect the presence and position of the bolt within the strike box, ensuring the door is securely latched.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing sensors are installed separately on the door and molding to detect door orientation, then door position detection capability is achieved, but installation time increases and aesthetic appearance deteriorates
Solution Approach 1:
The patent combines multiple sensing functions (magnetic sensor, optical sensor, and door position detection) into a single integrated sensor assembly that is installed in one location on the molding. This eliminates the need for separate magnet and sensor installations on both the door and molding, reducing installation time while maintaining detection accuracy through the coordinated operation of multiple sensors within the unified assembly.
2Adaptability or versatility
If multiple separate components (magnet and sensor) are installed on door and molding, then door orientation detection is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The sensor assembly integrates multiple sensing components (magnetic sensor, optical sensor, and processing circuitry) into a single unified device that performs door orientation detection, bolt position detection, and latching status determination. This consolidation reduces the number of separate components that need to be installed and configured, thereby reducing installation complexity while maintaining full detection versatility.
Solution Approach 2:
The integrated sensor assembly performs multiple functions: detecting door orientation (open/closed), monitoring bolt position (retracted/extended), and determining latching status (secured/not secured). This multi-functional design eliminates the need for separate specialized sensors for each detection task, simplifying the overall system while maintaining comprehensive monitoring capability.
3Measurement precision
If existing sensors are installed separately on door and molding, then detection capability is achieved, but aesthetic appearance deteriorates
Solution Approach 1:
By consolidating all sensing components into a single sensor assembly installed in one location on the molding, the patent eliminates the visual clutter of multiple separate magnets and sensors distributed across the door and molding. The unified assembly presents a cleaner, more streamlined appearance while maintaining accurate bolt location detection through the coordinated sensing of multiple parameters from the integrated component set.

AI summary
A sensor assembly includes a sensor located within an opening formed in a strike box of the strike assembly. The sensor, which could be an optical, mechanical, continuity, inductive, ultrasonic, and/or mechanical sensor, is configured to detect whether the bolt of the bolt assembly is encompassed by the strike box. The sensor assembly is configured to interact with a surface of the bolt when the bolt is located within the opening.
