Lock Sensor Assembly for Door Panel Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock sensing systems for doors and windows fail to accurately determine the locked state by considering both the position of the locking member and the panel, leading to incorrect determinations of the door or window's locked status, and are often complex to retrofit.
Innovation Solution
A sensor assembly is integrated into the door or window system that senses the position of the locking member and transmits signals indicating whether the panel is locked in a closed or intermediate position, using inductive sensors and a transmitter to provide accurate locked status information to users, including wireless communication options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a lock sensing system only detects the position of the locking member, then the sensing arrangement is simpler, but the locked status determination becomes inaccurate when the panel is not in a closed position
Solution Approach 1:
The patent combines two sensing functions into a single sensor assembly: detecting both the locking member position and the panel position. This merging allows the system to accurately determine locked status by evaluating both conditions simultaneously, resolving the contradiction between system simplicity and measurement accuracy.
Solution Approach 2:
The sensor assembly acts as an intermediary that correlates the position of the locking member with the position of the panel. By using this intermediary device, the system can distinguish between a locking member in position when the panel is closed (true locked state) versus when the panel is open (false locked state), thereby improving determination accuracy without significantly increasing complexity.
2Adaptability or versatility
If a lock sensing system is integrated into existing door or window systems, then the functionality is added, but the installation becomes complex and difficult to retrofit
Solution Approach 1:
The sensing system is divided into separate functional modules: a sensor assembly that can be independently installed on the panel or frame member, and a control unit that processes the sensor signals. This segmentation allows the sensing functionality to be added to existing door or window systems without requiring complete system redesign, making retrofitting easier and more adaptable.
Solution Approach 2:
The sensor assembly is designed with universal mounting capabilities that can be applied to various door and window configurations. The sensor can detect both locking member position and panel position across different system architectures, providing adaptable lock sensing functionality that works with existing diverse door and window designs without requiring complex custom installation for each case.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sensor assembly accurately determines the locked status of doors and windows by considering both the locking member and panel positions, preventing incorrect determinations and allowing for easy integration without complex retrofitting, enabling users to monitor the locked status effectively.
Implementation Method 1
the sensor assembly comprises a sensor, wherein one of the panel or frame member comprises a locking member and the sensor is positioned on the other one of the panel or frame member
