Secure Window Assembly With Key-Locked Ventilation Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Secure windows often require a configuration that balances heat retention and ventilation while maintaining security, and existing locking mechanisms can be easily bypassed, compromising security during maintenance or cleaning.
Innovation Solution
A secure window design featuring a removable element secured by a latching lock that requires a key for removal, ensuring ventilation without compromising security, and a method of assembly that integrates a latching lock to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable element is used to facilitate maintenance and cleaning, then ease of operation is improved, but security is worsened because the element can be easily removed without proper authorization
Solution Approach 1:
A removable element acts as an intermediary component between the first and second window assemblies. This element requires both a latch mechanism (for secure attachment during normal operation) and a key (for authorized removal during maintenance), thereby mediating between the need for easy maintenance access and the need for security against unauthorized removal.
2Ease of operation
If a latch mechanism is used to secure the removable element, then ease of operation is improved, but security is worsened because the latch can be released from the inside without a key
Solution Approach 1:
The locking mechanism is segmented into two distinct functions: a latch portion that engages with a latch recess for secure attachment during normal operation, and a key-operated locking portion that prevents unauthorized removal. The key interacts with a keyway and locking mechanism separate from the basic latch, dividing the security function into layers that address different operational needs.
3Ease of operation
If ventilation is provided through the ventilated security panel, then ease of operation is improved, but security is worsened because objects can potentially be passed through the open window configuration
Solution Approach 1:
The security panel is designed with localized ventilation apertures that allow air passage while maintaining overall security. The removable element with its specific geometry (including the T-shaped cross section and internal face plate) provides ventilation in specific localized areas while the surrounding structure maintains security properties, allowing ventilation without compromising the overall security function.

AI summary
A secure window is shown that provides ventilation, having a first window assembly 101, a second window assembly 102, a ventilated security panel 201 and a removable element 812 locatable between the first window assembly and the ventilated security panel. The first window assembly is attached to a first frame component and the second window assembly is slidable between a closed configuration and an open configuration, such that ventilation is provided through the ventilated security panel when the second window assembly is in its open configuration. The ventilated security panel is removably retained by a second frame component and the removable element, and the removable element is secured to the first window assembly by means of a latching lock 501. The latching lock extends from the first window assembly and is arranged to be inserted into an opening 802 in the removable element without a key, to become locked in position. The latching lock is only removable from the opening upon the deployment of a key, thereby becoming unlocked to facilitate the removal of the removable element.
