Window Guard Release Mechanism for Emergency Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door protection systems are not easily removable in emergency situations, such as fires or earthquakes, posing a risk as they require complex operations and special training, and may hinder evacuation processes.
Innovation Solution
A protection device with a release mechanism integrated into the window frame, allowing users to easily remove the guards using a simple and accessible mechanism, ensuring safety while maintaining structural integrity and minimal impact on the building.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed protection system is used to prevent falls, then safety is improved, but ease of removal in emergency situations deteriorates
Solution Approach 1:
The protection system transitions from a completely fixed structure to a dynamic system with a release mechanism. The bars remain fixed during normal operation to ensure safety, but can be quickly released when needed for emergency evacuation, allowing the system to adapt between two states: secure and removable.
Solution Approach 2:
A release mechanism acts as an intermediary component between the fixed protection bars and the window frame. This intermediary element enables easy removal of the bars while maintaining their secure fixed position during normal use, resolving the contradiction between fixed safety and easy removal.
2Ease of operation
If a movable protection system is used to allow removal, then ease of operation is improved, but reliability deteriorates due to risk of easy manipulation by children
Solution Approach 1:
Different parts of the system have different properties: the protection bars maintain a fixed, secure quality to prevent manipulation by children, while the release mechanism provides a localized area of ease of operation accessible to adults. This spatial differentiation of qualities resolves the contradiction between security and ease of removal.
Solution Approach 2:
The release mechanism changes the operational parameter from requiring significant force or complex manipulation (secure against children) to a simple release action (easy for adults). The mechanism transforms the interaction between user and protection system, allowing easy removal only when the correct release action is performed.
3Reliability
If a complex release mechanism is used to ensure security, then reliability is improved, but device complexity increases
Solution Approach 1:
The release mechanism is segmented into simple, discrete components rather than a complex integrated system. This segmentation allows the mechanism to provide reliable security functionality while keeping each component simple and the overall device complexity manageable.

AI summary
The present invention refers to a protection device for windows, doors or open spaces with release arrangement (1) which maintains a mechanism that allows the generation of an opening in windows, doors or open spaces that have protections where these can be displaced in a situation that so requires allowing the generation of an additional output that in case it is not required provides a window of normal appearance.
