Adjustable Window Security Device with Sliding Magnet Track
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window security systems lack flexibility in allowing users to select a preferred partially open position for venting, as the pre-set vented position may not align with the user's ideal choice.
Innovation Solution
A security device with a magnetic member housed in a track system that allows adjustable positioning along a window, enabling the magnetic member to be slid to different locations for varying venting positions, while maintaining anti-intruder protection by using a contact switch to transmit closed or open signals based on the magnetic member's proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two magnets are attached to the window at fixed positions, then the security device can detect closed and vented positions, but the end user cannot adjust the preferred vented position
Solution Approach 1:
The magnetic member is made adjustable rather than fixed, allowing it to be repositioned along the window jamb to different vented positions. The housing contains a magnetic member that can be moved to different locations and secured at desired positions, providing dynamic adaptability while maintaining security functionality.
2Adaptability or versatility
If the magnetic member housing is made longer to allow adjustment, then the magnetic member can be positioned at multiple locations, but the device occupies more space on the window
Solution Approach 1:
The housing is segmented into functional zones: a magnetic member reception area, an elongate body providing structural support and housing for the magnetic member, and mounting features. The elongate body extends along the window jamb to provide adjustment range, but the magnetic member itself remains compact within the housing structure.
3Length of stationary object
If the magnetic member is made smaller to reduce housing size, then the device is more compact, but the magnetic field strength may be reduced
Solution Approach 1:
The magnetic member is positioned at specific locations within the housing to optimize its function. The housing contains the magnetic member in a reception area that positions it effectively for detecting window positions. The magnetic member's size and position are optimized to provide sufficient magnetic field strength for reliable reed switch activation while maintaining a compact overall device size.

AI summary
A security device that is adapted to be affixed along a window to provide anti-intruder protection while providing the ability to open the window a variable amount for venting an area. The security device comprises a magnetic member, located in a housing, and means for mounting the magnetic member at a desired location along the housing. The means for mounting the magnetic member may comprise a track extending substantially along the length of the housing and means for slidingly engaging the magnetic member along the track, whereby the magnetic member may be engaged at a desired location. The security device further comprises a contact switch adapted to provide a closed signal to a security system when the contact switch is in proximity to the magnetic member and an open signal when the contact switch is not in proximity to the magnetic member.
