Window Handle With Integrated Sensors And Electromechanical Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current window and door handles lack efficient monitoring and locking mechanisms, leading to potential unauthorized openings and manual locking/unlocking requirements, which can result in security vulnerabilities and inconvenience.
Innovation Solution
A handle with a rotatable second part, a coupling element, and an electromechanical locking element, along with integrated sensors (3D acceleration, magnetic field, and contact/proximity sensors) for condition monitoring, enabling detection of handle and door/window positions, and an alarm system for enhanced security and automation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional locking mechanism with key is provided, then burglary protection is improved, but device complexity increases and manual operation is required for each handle
Solution Approach 1:
The patent replaces the traditional mechanical key-based locking system with an electromechanical locking mechanism controlled by an actuator. The locking element can be actuated electrically through the handle's integrated circuit, eliminating the need for physical keys and enabling remote or automated locking operations while maintaining security functionality.
Solution Approach 2:
The handle is designed to perform multiple functions: it serves as both the operating mechanism for opening/closing the door and as the control interface for the electromagnetic locking system. The integrated circuit board within the handle coordinates both the mechanical actuation and the electromagnetic locking control, reducing the need for separate key-based systems.
2Loss of information
If detector transmitters are attached separately to monitor window/door position, then monitoring capability is improved, but device complexity increases and visual appearance is degraded
Solution Approach 1:
The patent integrates the monitoring functionality directly into the handle assembly. The handle contains sensors and an integrated circuit that detect the door's open/closed state and locking status, combining the operating mechanism and monitoring system into a single unified component rather than requiring separate detector transmitters attached to the door and frame.
Solution Approach 2:
The handle serves dual purposes: it is both the mechanical operating element for the door and the monitoring device for detecting door position and locking status. The integrated circuit processes signals from sensors within the handle to determine whether the door is properly closed and locked, eliminating the need for separate monitoring components.
3Ease of operation
If manual locking/unlocking of each handle is required, then ease of operation is worsened, but device complexity is reduced
Solution Approach 1:
The patent replaces manual key-based locking operations with an electromechanical actuation system. The actuator, controlled by the integrated circuit, automatically moves the locking element between locked and unlocked positions based on signals received or commands issued through the handle, eliminating the need for manual key insertion and turning operations.
Solution Approach 2:
The locking mechanism is designed to operate automatically through the handle's integrated system. When the door is closed and latched, the system can automatically engage the locking element without requiring user intervention, and can be unlocked through the handle's interface, reducing manual operational steps.
